After the workers were dismissed, some of them ran back to the workshop to take out wooden or bamboo utensils and lined up at the small table. Others stood in the doorway and waited. After a while, I only heard a rumbling sound, and the workshop supervisor pushed it with a few people

A small car is back. The people waiting at the door quickly surrounded them, watched the supervisor take out the key, open a large bamboo cage placed on the car, and took out lunch boxes from it and handed them to the people around them. And as soon as these people got the lunch box, they were also quickly there

There is a queue in front of the small table.

The people who came to deliver the food were actually guys from a restaurant in Dongmen City. The indigenous workers in the optical workshop use a subsidized contract system, and choose one each month - either a canteen run by the industrial zone or a qualified restaurant in Dongmen City. The

The supplier is responsible for providing nightly meals to all workers during the month. Generally speaking, people who do not have a family want to save trouble and choose all-inclusive meals, while those who have a family only buy vegetables, and the rice brings their own rice and steam it in the factory's steaming cabinet. It's also not a hassle to do so, go to work

The lunch box filled with rice and water is sent to a special cage in the optical workshop in the steaming cabinet, and the supervisor is responsible for locking it. When the time comes, someone will be responsible for opening the valve and putting the industrial steam into the steaming cabinet, and the rice will be steamed in no time.

Lin Hanlong looked at today's dishes, as usual, there should be meat today. When the guy who delivered the food saw him coming, he quickly stood up and said respectfully: "Chief Lin! Today's delivery is bean curd fish and fried carrot shreds. The soup is a seafood offal soup. In addition, there are a few small refreshing things

The dish was delivered from the counter. ”

Lin Hanlong saw a vegetable bucket cooked red, which indeed looked like tofu and fish fillet. He took a spoon and stirred it in the pot, confirming the ratio of fish to tofu inside, and nodded. Fish fillets are more common now. Since there is cold storage, cover again

A fish processing plant was set up, and every fishing flood would be open to purchase, and there was a lot of inventory. The cold storage will often clear the old goods and make room for new ones. Needless to say, these old goods have been warmly welcomed by the vast number of indigenous people and caterers. Lin Han

Long looked at the shredded carrots in another bucket, which looked shiny and lovely in the light. Lin Hanlong sneered this time and did not speak. The fellow chuckled dryly, his expression rather embarrassed.

Lin Hanlong understood that this shredded carrot must have been "fried" in salted water, and it cooled for a while after coming out of the pot, and then added some oil and stir-fried it slightly. In this way, the oil can only hang on the surface of the shredded carrots and cannot penetrate into the dish, which of course looks oily and lovely. He rummaged through the soup bucket again, glanced at the pickled radish skin, old vegetable stalks and other "refreshing side dishes", and walked away without saying anything

Finish.

He heard someone behind him whispering, "Your chief is really a good man." He didn't look back, and walked straight back to the workshop. A wry smile appeared on his face. Carrots are rich in vitamin A and are a precision machine that needs good くなのしか to work

Mechanics are vital nutrients. However, the vitamin A of carrots is oil-soluble, and the nutritional value of such shredded carrots with "bright oil" is greatly reduced.

Speaking of which, he was the only one who really cared about the food of the indigenous workers. The workers themselves don't care about the quality of the food, as long as they can eat brown rice, they are very happy, and the dishes belong to the food. Even if it is a daily supply of pickles

People will also be satisfied. Lim's reason for caring about food is simple: people in this era are generally malnourished and often unable to concentrate on delicate work for long periods of time. Especially when the optical workshop starts at night, the light is not as good as during the day, and many people can't even see the workpiece clearly. Lin Hanlong can enhance the lighting in the workshop, but that would consume precious gas and increase the fire hazard. So he prefers to pay for his workers to eat better. The problem is that Lin Hanlong has limited funds and cannot cover all their meals. So he came up with a subsidy method, so that the workers could work together to make a one-to-one subsidy according to the food expenses paid by the individual. In this way, the situation has improved, but the responsibility of the canteen is limited, and the interest of the outside merchants is to maximize the profit as much as possible. Although Mr. Lam personally sets the menu – for example, the fried carrots – there is always a way to save money. He knew that some things couldn't be taken care of too carefully, but next time he did this, he would have to consider changing suppliers.

Lin Hanlong walked a few steps and turned around, and ordered the apprentice who was following him to give him a hot meal. Seeing that the apprentice nodded in agreement, he walked into the office, went around to the back and unlocked a door, entered his own cubicle, and closed the door. In the cubicle were a few of the professional books and a large amount of scratch paper, as well as a laptop. This ruggedized Panasonic toughbook was purchased specifically for the crossing and has been used for several years without any problems. However, for the sake of prudence, Lin Hanlong still removed the battery for separate storage, and replaced it with a simple rectifier UPS powered by mains power and a set of lead-acid batteries under the computer desk. He turned on his computer and waited for a while, watching Ubuntulinux boot up quickly. Without his hands, the computer automatically opened the internal forum and video-on-demand server of the crowd after it was started. Lin Hanlong didn't have time to review the film and television works he brought now, so he simply looked at the forum. Tonight, as usual, a number of active (or big-mouthed) IDs put forward a bunch of unreliable proposals, and a bunch of people replied to the post, started a war on the forum, and added more chats, farts, wharts, complaints, etc. Lin Hanlong hurriedly skimmed through it, replied briefly to a few more posts, and closed the forum page. He then opened a terminal and connected to the main server of the Traveler.

The apprentice knocked on the door outside the cubicle and told Lin Hanlong that the meal was ready. He opened the door and took his meal, then went back to his computer. Logging in to the "National Computing Service Center", entering his identification number and the authorization number of the Computing Service Center, he ran a few more programs, and a large number of graphs began to appear on the screen. Lin Hanlong studied the charts while eating the maid cooked for him and the apprentice gave him a hot "lunch". These charts are part of Lim's work. He used the free time of the server in the middle of the night to run the large design program brought by the pre-traversal on the server, analyzing and optimizing various optical designs.

The computing server of the Senate is a combination of 86 systems, after all, it is not easy to purchase a small or medium-sized computer in the old time and space, and money is only one aspect.

In contrast, the array computing server built using the 86 system has a simple structure and is not bad in function.

Lin Hanlong didn't know where the computer room of the main computing server was, but it should be in Bairen City, and the communication lines of the traverser were not enough to be luxurious enough to set up a computer room in the high mountain range.

This "National Computing Service Center" provides large-scale computing services for various departments, but because there are so many departments that need to calculate, they have to queue up in advance to get computing time. However, in the middle of the night, as usual, few people use this system, so Lin Hanlong always uses computing services in the middle of the night.

What is being done now is to use the Monte Carlo method to investigate the tolerance of various design options to manufacturing tolerances and changes in heat and cold. Due to the originality of Lingao Optics production and the difficulty of quality control, Lin Hanlong felt that it was necessary to start from the design aspect, and to tolerate all kinds of production errors as much as possible while maintaining a certain level of accuracy. While the computers he brought with him were still functional, he planned to analyze as many common optical system configurations as possible, and then make the results into complex tables and print a book, which he planned to use as a basis for future computer failures to produce an "optical design manual" that could also be used by indigenous people.

Looking at the results of the computer, Lin Hanlong couldn't help but nodded. When he crossed, he brought a lot of professional books on optics, and there were also some related materials in the big library. Over the past few days, he has done a lot of simulations of various classic designs introduced in several design manuals, and he feels that his understanding of these designs has been greatly deepened. There are essentially only a few kinds of optical instruments that the traversers need at this stage, and even fewer need to be mass-produced, and he feels that it is not a problem to meet his needs at his current level. After he has collected all the data he needs, it is not too difficult to make some more demanding designs.

Of course, being able to design is not the same as being able to reliably build it. Thinking of this, Lin Hanlong sighed again. It is difficult to set up the entire process, and it is even more difficult to teach illiterate indigenous workers by hand. It will be at least a year or two before they can become teachers and operate basically independently. Lin Hanlong thinks that he is not a very patient person, but if he doesn't want to die of exhaustion, he can only teach others patiently.

It was getting noisy outside. After the workers finished eating, they returned to the workshop one after another. Before the start of work, many people sat or stood, gathered together to talk and laugh casually. Some people squat in the smoking area outside the door smoking and drinking tea. Lin Hanlong looked at the computer, the time was almost up. He got up and opened the door and went out, beckoning his apprentice and a few supervisors to come over and check the results of the morning's work together. Seeing that the processing quality of the workpiece was acceptable, he instructed the apprentice to write down a few things that needed to be adjusted, and he returned to the computer room.

He minimized the window for the simulation and opened SOLIDWORKS again. An image of a nautical sextant appears on a computer screen. It was a project he had collaborated with several other veterans who were working on mechanics, led by him and assisted by others. This is an important scientific research project proposed by the Navy, and like the navigation clock, it is an important equipment for measuring latitude in the open sea, and it is of great significance to the Navy and the shipping department.

The sextant on the screen is already complete.,There is no problem with the simulation of the optical path.,The mechanical problems have also been improved.,Just wait for Zuihou to confirm the practice of the scale to make a real thing.。

There were two rings outside, which was the workshop supervisor ringing the bell to remind everyone to go to work. Lin Hanlong sat and didn't move, just pricked up his ears to listen to the movement outside. Over the past few months, he has become familiar with the noise emitted by the operation of various machinery, and he can know the state of the machinery as long as he listens carefully. If he doesn't come forward, he can also look at the actual level of the natives. It seems to be a bit of luck tonight, and all the machines sound like they're working properly. He turned his attention back to the computer.

Time always flies in front of the computer. By the time he finished reviewing the design of the sextant and uploading the design file to his colleagues, it had been more than an hour. After turning off the computer, he came out of the small room with his lunch box and locked the door casually. His apprentice was reading a book at his desk in the office outside.

Lin Hanlong looked at the content of the book, which was a primary mathematics textbook written by the people themselves.

"Junjie," the apprentice looked up at him. "In the explanation to the day shift, make a note that the belt of the No. 2 grinder is to be checked."

The apprentice nodded busily. "Yes! Master, I don't think that voice is quite right. It seems that a few nail heads are loose. ”

Lin Hanlong snorted and stretched out his hand again. "Have you done your physics homework?" He spent more than a year teaching his apprentice basic arithmetic, and let him go to school to recognize more than 1,000 Chinese characters. After the optical factory was changed to a night shift, the apprentice worked with him every day. So Lin Hanlong arranged for him to listen to two classes in the morning every morning, mainly mathematics, physics and chemistry courses from high school to junior high school. When he has time, Lin Hanlong will also give him extra lessons. Some time ago, he was responsible for rewriting the "Beginner of Light Theory" issued to the outside world, and he used the principle of convex lens and concave lens at the junior high school level to analyze several optical instruments that already had rudimentary forms in time and space. His apprentice became the first reader of the book. Because he heard and saw it every day, and had a little mathematical foundation, the apprentice roughly understood this book. However, Lin Hanlong privately thinks that even if this book is sent out, it can make people read it in a fog at most, and it is difficult for people who do not have a junior high school mathematics level to understand the calculation process. The level of his apprentices was far superior to that of any native of his time.

Lin Hanlong took a quick look at his apprentice's homework, and while holding a pen or hook or fork, he drew circles in more critical places.

"Here, and here, I don't think you understand it yet. I'll tell you about it after work. He looked up again and turned, "Also, you can take two of those jars on my desk and go home." Remember that the jar is going to be sent back. ”

"Master!" The apprentice exclaimed, "This, I can't stand this." Those cans are "trial products" sent by Wu Nanhai, which contain Lingao's homemade fried dace, which is quite similar to the classic canned products that have endured for a long time in later generations.

The apprentice knew that this was a "super high-end food" that only the patriarch could enjoy, not to mention the naturalized apprentices, even a few rich masters in the Dongmen City who didn't know how to spend it couldn't buy it.

Lin Hanlong glared at him: "Let you take it, you and your brother will have one can each." Eat well to have the energy to study, understand? And your brother's math and physics homework, which I will bring to see tomorrow. "Choi's younger brother, Zeiss, is a full-time student at Parkview Green and has good grades. After interning in the optical factory several times, Lin Hanlong felt that his understanding was good, and he had the heart to train him to become a jishu personnel in the optical industry.

"Yes, I'll bring it tomorrow night."

He waved his hand, "Put on your coat and let's go on a patrol." ”

By three o'clock in the morning, the workpieces processed on each grinding machine had completed the current process. Lin Hanlong watched as the workers used Lingao's self-made knife edge measuring ring to check the radius of curvature of the workpiece one by one. The workers of the grinding machine shift work in pairs, one is responsible for reporting the number and the other is responsible for recording. When a person finishes measuring, they switch roles and repeat the measurement process. After they were all done, Lin Hanlong himself stepped forward to spot check a few to see that there were no problems before letting them sign off from work. After a while, someone came over with a few boxes and put them in front of Lin Hanlong, which was a batch of newly assembled telescopes in the assembly workshop. Lin Hanlong picked one casually, looked at the standard calibration pattern posted on the wall, and then handed the telescope to the apprentice for careful acceptance.

There is already a faint light in the sky. The grinder shift is cleaning the piece he is responsible for with a broom and a rag, and the mechanical squad is busy oiling and maintaining the machinery. Lin Hanlong held a cup of strong tea in his hand and yawned as he watched the remaining workers finish the finishing work. At six o'clock, the day's work in the optical workshop came to an end. In accordance with the 4S standard formulated by Lin Hanlong, the workers received all the workpieces into the designated cabinet, the machinery was set to the state of shutdown, and all kinds of supplies were also placed in the designated position. Lin Hanlong didn't bother to lecture again, and then let them disband and go home directly.

"Junjie, what else do I have for this morning?" After leading the supervisors around the empty workshop, Lin Hanlong asked people to lock the door of the workshop and asked.

"Master! After the regular meeting at 8 o'clock in the morning, there is a meeting with the head of the exhibition, which is between 8:30 and 9 o'clock. Would you like to go back to eat and rest first? The apprentice followed Lin Hanlong and reminded.

Lin Hanlong nodded. After a while, the group of three people walked out of the factory gate and walked down the street. The sky was already bright, and there were already many pedestrians on the street. Fortunately, the weather was still cool, and it was quite comfortable to walk on the road. He was going to get a bite to eat when he got back and squint. The night in the optical workshop is over, and his day is not over yet.
