"Look, 50mm magnifying glass, f/quarter. [Read the latest chapter]" Lin Hanlong took out the magnifying glass and handed it to Wu Nanhai. Wu Nanhai picked up the writing paper on the table and looked at it with a magnifying glass.
"Well, you did a good job. It's very clear." Wu Nanhai clicked his tongue and touched the handle of the magnifying glass with his hand. "If it weren't for this wooden handle, I would have thought we brought it."
"Most high-end magnifying glasses are made of natural materials, and wood is just one of them."
Wu Nanhai put down the magnifying glass and nodded. "Okay, no problem at all. In our agricultural department, the more the better for this kind of thing." He turned back to greet the naturalized citizen staff, "Go, collect the bill of lading and let them go through the delivery procedures."
"Very good, this will clear up both sides."
"By the way, do you think the sugar meter I mentioned last time is ready?" Wu Nanhai's voice became solemn as he said that, and avoidance was the real purpose of his visit.
"Oh, that." Lin Hanlong took out a box from the drawer as if nothing had happened. "I made one. Take a look."
The sugar meter is a rapid detection instrument that uses optical principles and is specially used to quickly measure the concentration or refractive index of sugar-containing solutions and other non-sugar solutions. It plays an important role in sugar production, food, beverage and other industrial and agricultural production fields. In addition to measuring sugar content, it can also be used to measure the concentration of various sauce products such as soy sauce and ketchup. In agricultural production, it is suitable for determining the accurate harvesting period of fruits and sugar crops and classifying sweetness.
The principle is that light will be refracted when entering from one medium to another, and the ratio of the sine of the incident angle is constant. This ratio is called the refractive index. The content of soluble solids in fruit and vegetable juices is directly proportional to the refractive index at the same temperature and pressure. By measuring the refractive index of fruit and vegetable juices, the concentration of fruit and vegetable juices can be found.
The sugar meter that Wu Nanhai took out basically looked like a sugar cane with one end sharpened at an angle. The pointed end was inlaid with glass, and there were several knobs at the other end of the cylinder. Wu Nanhai picked up the sugar meter and brought it to his eyes, pointed the tip towards the light, and adjusted the knob with his fingers. He turned to Lin Hanlong, "Old Lin, I'm sorry, I want to take a look."
Lin Hanlong nodded. "As it should be."
Wu Nanhai turned his head. "Chu Qing! Bring those bottles."
The bottles are filled with water and sugar water mixed in different proportions. Wu Nanhai first put a few drops of water on the glass and then adjusted the knob. Lin Hanlong handed over a flannel cloth, Wu Nanhai took it, wiped off the water droplets, and then added sugar water. He squinted his eyes and looked at the light for a while, then wiped away the sugar water and replaced it with a bottle, then added a few drops to see. After repeating this several times, he put down the sugar meter and exhaled.
"Old Lin, you are really good! This thing is very well made, and the sugar content measurement is very accurate." Wu Nanhai was smiling all over his face at this time. "Very good, very good. I want as much of this thing as I want. I'll have someone report it later."
Lin Hanlong nodded. "Just sign the form and stamp it with the agricultural committee's seal later. You can take this sample away now." He took out a wooden box from the drawer, opened it and handed it to Wu Nanhai, "The matching box .”
"The lenses here are mass-produced goods, no problem. But the prisms are ground by hand. For mass production, we have to wait for the surface to be ground."
"Oh, how long will it take? I plan to send a batch before the next harvesting season and teach them how to use it in advance."
"You have to ask the Navy. They are in urgent need of binoculars and they plan to install two on each ship."
"How much will it cost? Sucrose is an important source of income for us, so we can't throw it away." Wu Nanhai said anxiously. He was also driven into panic by Wen Tong - Wen Tong promoted sugarcane production combinations in Leizhou and engaged in the cultivation of improved varieties. Pricing based on quality is an important part of Leizhou's sugar industry policy. Without a sugar meter, the rules and regulations formulated by Wen Tong cannot be used. Implement it concretely.
"Who says it's not?" Lin Hanlong agreed casually, but did not give any specific indication that Wu Nanhai had woken up; "I will help you tell the executive committee that optical instruments are too important and we need to increase investment."
"With your help, one can stand up to the three of them."
"Hahahahahahahahaha..." Wu Nanhai laughed a few times and raised his hand. Chu Qing quickly opened a straw bag that he brought with him and took out a wooden box from it.
"This is a new cigar from the farm. Please try it."
"No, no, I haven't finished smoking the limited edition you gave me last time..." Lin Hanlong became polite.
"Try something new. This time it's Li Quan's limited edition." Wu Nanhai smiled, "Try it. I asked the Jesuits to get the tobacco leaves from Macau, and the real wrappers are made from the Caribbean."
Lin Hanlong thought for a long time before he remembered who Shu Liquan was. He smiled and took the box. The box is made of a precious wood and exudes a light woody fragrance. According to Wu Nanhai, the wood was imported from Southeast Asia. The polished white wood lid was stamped with black fonts and even had extra-cursive characters that he didn't recognize. The box also has a green sticker with the word "tax-free" from the Monopoly Bureau of the Ministry of Finance.
It looks very impressive.
In comparison, the last limited edition was just cardboard packaging. It goes without saying which one is more advanced. Lin Hanlong discovered that the packaging description of Li Quan's limited edition was "three pieces included", and couldn't help but secretly scold Wu Nanhai for becoming more businesslike.
"Not bad, not bad." He also said haha. Wu Nanhai took out two more glass bottles from his pocket.
"This is fruit wine made from blueberries grown by Xue Ziliang at my place. The alcohol content is not high. You can have a drink. It's hot enough here."
"Why is this so embarrassing? You always bring things..." Lin Hanlong felt a little embarrassed. In recent months, Wu Nanhai has been sending things here and there.
"It doesn't matter. You are busy with work here and work late shifts every day, so you need to supplement your nutrition." Wu Nanhai disagreed, "Isn't the farm just for serving the elders?"
Wu Nanhai said as he swayed out, still holding the sugar meter box in his hand. His naturalized people filed out after him. When he was about to walk out of the workshop, he caught sight of something out of the corner of his eye. He turned his head and looked around, let out a sigh, and then jumped out to a corner of the workshop.
"Old Lin!!!"
Lin Hanlong rushed out and met Wu Nanhai's eyes with a faint green light. He couldn't help but secretly said, "It's broken!"
Fatty Wu tremblingly pointed at a row of curved cast iron workpieces with his fingers, and said in a trembling voice: "Show, show, microscope... you, why didn't you tell me." He was pointing to a row of microscopes. The mirror base is no different from that used by later generations.
Lin Hanlong smiled bitterly and said, "You didn't even ask me if I could do it. These are set by the Ministry of Health, and we need them very urgently."
Fatty Wu jumped up immediately. "I didn't ask because I thought it was difficult to make! Didn't it say mass production was only possible in the 19th century?"
"I used Leeuwenhoek's method, using surface tension to make aspherical lenses. It's quite easy to make." Lin Hanlong pretended to be calm and authentic, "Of course, with slight improvements, we can produce products of multiple specifications with high accuracy. Within one percent.”
Wu Nanhai stared at Lin Hanlong for a while and laughed. "Old Lin! When it comes to optics, you belong to us! You can do what others can't!"
"That's not the case, there's more"
Wu Nanhai patted Lin Hanlong's shoulder heavily: "Old Lin! You have made a great contribution to the work of our Ministry of Agriculture! I, Wu Nanhai, understand very well!" Fatty Wu patted his chest, "Don't talk nonsense. Yes, our Ministry of Agriculture will strongly support the work of the optical factory in the future. Such an important matter should be put in a priority position for development.
Executive Committee, I'll take care of it! "
The two laughed for a while again.
Wu Nanhai suddenly remembered something. "Old Lin, according to your habit, you must have made a few test products before mass production, right?" When he said this, the green light emitted from his eyes was enough to illuminate the entire workshop.
Except for being a little rougher, the homemade microscope Lin Hanlong took out seemed to be no different from later products at a glance. He pointed at the objective lens and said, "There are three magnifications, 50, | 50, but the positioning mechanism is not very good. You have to be careful when turning it, and adjust it slightly to prevent the light path from being incorrect." He pointed to the eyepiece again; "Continue The eyepieces are not painted, so wipe them clean after use, otherwise sweat will corrode them.”
Lin Hanlong found a piece of cloth to wrap the microscope; "There is no box, so you can just hold it. This is a trial product. There are still many minor problems. Please pay attention when using it. If you have any questions, tell me."
"Easy to say! Easy to say!" Wu Nanhai walked out with satisfaction, holding the sugar meter in his left hand and holding the microscope tightly in his right hand.
After sending Wu Nanhai away, who looked like a Japanese soldier leaving the village, Lin Chalong asked his apprentice to get another towel to wipe his face, and quickly started his second inspection of the workshop. The professional level of the workers is not high, and even experienced workers are only half-understood. A half-full bottle of vinegar is the most dangerous. Bad things happen from time to time, making it almost impossible to prevent.
When Lin Hanlong had patrolled the grinding team halfway and was listening carefully to the sound of the machine, someone came to report that there was a money chief at the door looking for him.
Chief Qian has a strong build and obvious muscle lines. A veteran's standard outfit with a T-shirt and short black sunglasses, a pistol holster strapped to his thighs, and a gun handle with a square head and square head pulled out. Although it is a standard outfit, if you take a closer look, this outfit is actually very different from others. The sunglasses are like those of Tom Cruise in Top Gun. The plain T-shirt with a collar can actually look slim when worn. The shorts are obviously military products such as 51|. Even the shoes are not ordinary running shoes that can be seen on the market. .
The visitor took off his sunglasses, revealing a pair of bright eyes. It is Qian Shuiting, the current Speaker and leader of the House Party. "Old Qian! What wind has blown you away?" Lin Hanlong greeted him with a haha.
"I happened to go to the machinery factory for research today. I'll come over to your place after I'm done. How are you? Have you eaten?"
Lin Hanlong shook his head. "I don't have time. I'll ask the cafeteria to send something over later."
Qian Shuiting took out a big box from the straw pocket behind him; "I've prepared some things, why don't we eat some together?"
Inside the box were two large lunch boxes preserved with ice. Lin Hanlong glanced into the box. "Sushi! Where did you get this?"
There are pieces of rice balls in the box, rolled up with cabbage, etc., and covered with red fish meat. It was the Japanese sushi that became known to the world.
Lin Hanlong invited Qian Shuiting into the office. There were so many things on the desk that it was difficult to clean, so someone set up a small folding table and wiped it down to serve as a dining table. The two sat opposite each other. Lin Hanlong asked his apprentice to bring a few bottles of kvass - it was not convenient to drink seriously during working hours.
Qian Shuiting said that when he was working in California, he also worked in a Japanese restaurant, making sushi and so on. Unfortunately, there is no suitable sushi rice locally, so the taste is just about average. Of course, there is no sushi vinegar, but Tianchu has brewed white vinegar, so I can use it as a substitute for the time being. Feiyun can often go fishing at sea, and has made an appointment with some fishermen to deliver good products whenever they can, so the seafood and fish are still fresh. "Tianchu has Japanese soy sauce; after all, everyone often eats sashimi." Qian Shuiyan said, opening a lunch box "This is fresh mustard from Wu Nanhai - I grind it myself, not mustard paste."
"Speaking of Wu Nanhai, he just left my place." Lin Hanlong always adhered to the view that individual happiness is not as good as everyone's happiness. He picked up Li Quan's limited edition cigar from the table, "How about one later?"
"No, you better smoke it yourself." Qian Shuiting said, "I have to be strict with myself now."
At first, Lin Hanlong thought Qian Shuiting meant to take care of his body, but later he understood: "You mean you can't take gifts from others?"
"That's what it means."
"It's just a box of cigars... Lin Hanlong doesn't think much of this kind of private gift to attract affection. Almost everyone among the elders has a share.
Qian Shuiting shook his head; "We don't lack these circulation coupons, so it's better to buy them directly, so as not to stain the scenery. Old Wu is a very nice person, and he can't stand someone-" He probably felt that this was inappropriate, so he didn't say it .
"Do you think this is the United States..." Lin Hanlong felt that since Lao Qian organized the House Party and became the Speaker, his behavior was very different from before - a bit too neurotic. Politics is indeed not something ordinary people can do.
"It's not the United States that's why we need to pay attention. It would be easier if we were in the United States." Qian Shuiting poured him a glass of kvass as he said, "Shu, have a drink first."
After eating a few pieces of sushi, Qian Shuiting stared at Lin Hanlong: "Old Lin, I'm not talking about you. You are a little thinner than last month."
"Eh? I don't think so." Lin Hanlong has a great appetite, and eating cold food like sushi in hot weather suits his appetite.
Qian Shuiting picked up the chopsticks and nodded. "You're confusing right and wrong. You work all night, have meetings in the morning, and do things at the machinery factory. It's the hottest time at noon, how can you sleep well?" ?" He picked up a piece of sushi and put it in Lin Hanlong's bowl, "This is flying fish roe, very good. You should eat more. I can't sleep well, eat well and feel tired. Can you not lose weight? Your body still needs it. No more?"
“It is always difficult to avoid hardships in the early stages of a career.”
"Everyone is starting their own business, so you have to work harder than others."
"When the optical factory has an independent power source in the fall, we won't have to work the night shift. It will be easier then."
"That's it. The steam engines from the machinery factory are being shipped out one after another. Why does your optical factory, which is close to the water, have to wait until autumn?"
This time it hit Lin Hanlong's sore spot.
"You also know that some people in the executive committee said that it would not be too late for optics to develop in the second or third five-year period. What do you think?"
Lin Hanlong shook his head; "What do they know? I have so many people urging me to do this and that, but I can't do it."
"That's right! You all only understand your own one-third of an acre of land, who understands it better than the other? It's only been a few years, and you no longer listen to what the front-line veterans say."
"There is no one on the executive committee who is engaged in scientific research, not even a graduate student. He has no intuitive experience in scientific research and development."
"If this continues, it will be up to them to decide how to climb the technology tree? Isn't it true that laymen lead experts?"
Lin Hanlong waved his hand; "Forget it, let's eat." He was really hungry, and he quickly finished most of a large box of sushi. A bottle of kvass is enough to drink.
Qian Shuiting watched Lin Hanlong put down the kvass bottle and said, "I think there must be a voice to speak for the front-line technical veterans."
Lin Hanlong looked at Qian Shuiting and said nothing.
"Take your optical factory as an example. Many people think that we still have a lot of inventory and there is no need to rush. If I look at it, no matter how much inventory we bring, the categories will always be incomplete and the quantity will always be limited.
Lin Hanlong nodded in agreement. "People from all walks of life are asking me for a lot of things, some of which they have never heard of before."
"Old Lin, you are so busy that you are confusing right and wrong. It is not easy for you to say something. As the speaker, speaking is my job. I feel that I have to speak for the vast number of technical veterans. Qian Shuiting looked at Lin Hanlong sincerely, "I understand the importance of optics. But how far can we achieve at this stage? Can you explain to me?"
Lin Hanlong nodded again; "I'm sorry to trouble you." He was silent for a moment and organized his words.
"Optics, in terms of theory and design, our time and space are very mature things." He pointed at himself, "I am from the optics class, and I also do optical work. Design and other things, I can handle it." As for process manufacturing, it is not particularly difficult to say that it is difficult. Many enthusiasts can grind lenses by themselves, and I will not be worse if I am a professional. To put it bluntly, optical things are mainly a kind of precision machining, nothing more than The processing volume is relatively small, and there are relatively simple ways to make accurate measurements." He looked at Qian Shuiting and paused, "I dare say that as long as the resources are sufficient, I will be able to achieve the results before the 20th century in a few years. level."
Qian Shuiting was in a state of ejaculation. "Old Lin, you are so awesome here! It's great!"
Lin Hanlong nodded. "Seeing is believing. Last time you said you wanted to see my place, are you free today? I'm about to go on a inspection tour."
