In the Booming Era, I Earn Foreign Exchange for the Country

The writing is good, please update it. Cancel the English learning test for me later, and change English to majors related to foreign trade. Don't take major foreign language subjects.

The first thing I wanted to do was meet the teacher in person.

Integrated circuit chips were produced at the beginning. I was really convinced that at that time, the country could not even produce printed circuit boards, because there was no material, not even transistors, and the Americans did not have them.

The two paths of that era were to go to the state departments for construction. Otherwise, major manufacturers will conduct research. Others cannot protect people in turbulent times. Needless to say, the first one is that if the country wants to advance, it must not take people down. Second, some large companies themselves have enough status to protect people. If you have a high enough rank and have some law enforcement powers, you can survive hard resistance. Schools were the first to be liquidated. Because those students will be in many important positions later on, they must be pure.

The author structure is small. They are engaged in scientific research and have made huge contributions, but there are no great people. Mr. Zhou's interview, condolences, and no communication with other meritorious figures lacked a sense of reality.

If you fall in love, you will be expelled. If you write an article to shock the professor, you cannot shock the professor immediately. You must be notified by the school where you are expelled before you come to the rescue. The professor was shocked and could not let the talent go, so he asked the school to take back the punishment, showing that the protagonist was important. No, buddy, do you write fantasy? You can't write without showing off, can you? Get some character design, write about the technological progress of domestic methods, and then write about the protagonist inventing new technologies. Wouldn't it be more shocking and have a stronger sense of immersion? There are no technical details, just a 50,000-word paper, and no comparison. You don't want to suffer at all from searching for information.

How did you get into Sanjiang? This book lowered the standard of Sanjiang in this issue.

I couldn't stand the research on five-axis machine tools. I checked some information and found that the machine tool bed must be aged to remove stress, otherwise it will deform. That is, after the machine tool bed is cast, it must be left outside in the wind, sun and rain for at least three years, or it can be thrown into the sea. After the aging period, it can be processed. Then there is an automatic compensation system for thermal expansion and contraction. The machine will generate heat when running, and thermal expansion and contraction will directly affect the machining accuracy. There are many problems.

Ruipian is not a single product, it is an entire industry chain.

A half step ahead in technology is a genius; a step ahead is a monster; two steps ahead is a bastard; the industrial system is a whole set; single items stand out in the past, which is pure nonsense.

If you are the first to develop integrated circuits, your programming language will be based on Chinese language.

Even if this kind of article is a cool article, you have to talk about the most basic logic. If you don't talk about logic at all, it is recommended not to write this kind of thing. The era you set was in the 1950s when the People's Republic of China was just founded. Do you think your currency stuff is logical? I finally understand why we need to control related literature, because some authors have no logic at all, and what they write is simply slandering their ancestors.

To be honest, it is very amateurish and stupid to issue military orders for scientific research work, and this state of affairs has lasted for decades~

It was identified as a junk book. In those days, there was a shortage of electricity, steel, food, and semiconductors. Anyone who dared to criticize resources would get out.

The writing is incomprehensible and completely out of step with the times. Those who write about technology should first look at the history of integrated circuit development and then look at what they are writing about.

You can actually write material! ! Materials are the foundation. Without materials, you can't do anything! ! How do you solve the problem of integrated circuits with your materials! ! How to solve the problem of instrumentation! ! You can't make anything without materials, and you don't even know what you're making without instruments! !

To see this, you need to deposit it first🧠, it costs one yuan per pound

Dropping out of school is toxic at the beginning, but you can still watch the follow-up for the time being, so watch it first

First check what are the prerequisites for integrated circuits. Did China realize these conditions at that time?

At that time, the domestic industrial foundation was too weak. Even early semiconductors and early chips had a large amount of high-purity materials, fine chemical materials, precision measuring tools, and precision machining, and almost the entire system could not be completed. In addition, the talent base is even worse. Intellectuals are very valuable. Expelling for dating in college is different from expulsion for counter-revolutionary activities. Talents are already in short supply after being admitted to college in high school. There is no problem at all in returning to your hometown to become a secretary of the county party committee. The principal of my elementary school just graduated from elementary school and became a teacher in a village school.

After being reborn, he is still an experimenter with chip implantation. He always has countless knowledge and has been engaged in industry. He doesn't care about the material basis of life, and he doesn't care about hybrid rice. Basically, the protagonist has not changed anything, and disasters are still happening, even if you write it down and leave it to others. There are also those who have been engaged in high-tech finishing. With the technology of that era, they couldn't make much money, so why not engage in things like washing machines that can be mass-produced?

Chinese takes up too many bytes and the hardware performance is low This reason is valid on the surface, but it is untenable in the context of the story setting. · Ostensibly established: In the early computer era (memory is measured in KB, storage is measured in MB), a Chinese character occupies 2 bytes under GB2312/GBK encoding, while an English character only occupies 1 byte under ASCII. If the variable names and keywords are all in Chinese, it will indeed consume more storage space and processing time. · Reasons for being untenable: 1. The hardware was designed from scratch by the protagonist team - they could have designed a hardware that supports "Chinese compression encoding" or "custom symbol set". At the hardware level, defining a "Chinese simplified symbol" only requires 4-6 binary bits (up to 64 symbols), which is less than ASCII's 7 bits. 2. C language itself is not the most byte-saving language - C keywords (if, while, etc.) Occupy very little space at the source code level, but the size of the machine code generated by the compiler is the key. Using Chinese keywords or custom symbols has little impact on the final machine code size - because the source code will be compiled into instructions. 3. The performance bottleneck is not the number of bytes of the source code - In the 1950s and 1960s, the performance bottleneck of computers was the CPU speed and memory capacity, not the few Chinese characters written by programmers. A Chinese keyword occupies 2 bytes, and an English keyword occupies 1 byte. This difference in the compilation stage can be completely ignored. Conclusion: The author uses "hardware performance" as a reason to exaggerate the small compile-time differences as run-time bottlenecks, which is a stolen concept in technical common sense. If the protagonist is the only one from the local area, it can be explained as "he has a photographic memory" or "he brought a technical manual with him when he traveled through time". But the entire team is a local college student from the early days of the founding of the People's Republic of China, and no one has studied abroad, which means: · No one has ever seen a real computer · No one has read the original English technical literature · No one has ever been exposed to Western programming languages and operating systems In this case, to "invent" the C language out of thin air (a highly abstract, complex language based on English keywords that requires compiler support) is equivalent to asking a group of people who have never seen a car to draw the structure of a Ferrari engine on a drawing - and draw it correctly. This logical problem can be viewed at several levels: 1. The C language itself was not "imagined", but "evolved" The emergence of the C language has its historical path: B language → BCPL → CPL → Algol, each step is based on the actual application and problem feedback of the previous language. Concepts such as pointers, arrays, and stack frames in C language are abstractions of the hardware at that time (PDP-11, etc.). Without these hardware practices and the failure experience of previous languages, directly "inventing" the C language is like skipping the iron-making technology and directly building a high-speed rail. 2. The compiler/interpreter is a barrier that cannot be bypassed High-level languages ​​must have a compiler or interpreter to run. The compiler itself is complex software that needs a runnable environment to write it - this is the classic "chicken or egg" problem. In reality, the first C compilers were written in assembly, which in turn required machine code. How could a local team from the early days of the founding of the People's Republic of China possibly not even familiar with assembly write a C compiler that could correctly parse if-else, while loops, and function call stacks? 3. The English keyword itself is the threshold int, char, float, return - these English words were meaningless symbols for people with almost zero knowledge at that time. They need to learn the semantics of these English words before they can understand their usage in programming. A reasonable design should use symbols they are familiar with: Chinese, mathematical symbols, or even self-created graphics.

The most rubbish and unacceptable thing about this novel is the identity of the male protagonist. You can design it to be a college student who has returned from studying in the United States. In 1956, a rural person, a freshman, discussed photolithography machines, etching, photoresist, etc. What is the difference between this horse riding and the lighter designed by primitive people who drilled wood to make fire?

Talent, you can't give me poison. Starting a freshman. If you are a modern person, there is nothing to say. Where did you learn the knowledge and experimental data in the 1950s and 1956s? Hey, you start by writing an integrated circuit. Just write it down, you've even written down the process and how to do it. Doesn't this require experimentation? I know, you know, but if you don't experiment with this, where will you get the data? Ah, I really just write whatever I dream about.

Take a look at the beginning. Huh?

Looking at the introduction, the logic is confusing,

All I know is that humans can't imagine what they haven't seen

In 1956, we were reborn and built the world's first electronic calculator. Haven't you read this history? I'll go! The world's first general-purpose electronic computer, ENIAC, was developed in 1945 and officially announced to the public on February 14, 1946 at the University of Pennsylvania. It was developed for calculating artillery ballistics during World War II. It covers an area of ​​about 170 square meters, weighs 30 tons, and can complete 5,000 addition operations per second. It is a milestone in the development of modern electronic computers. They did it ten years ago, but you did it five or six years ago, ten years too late! Alas, he is also a human being

I thought you were an American spy and beat you to death.

It will be over after more than 300 chapters. You really have to write an egg!
