Zhou Xing stood in front of the comprehensive experimental bench, busy with concentration, sometimes writing code, sometimes debugging instruments, sometimes modifying data... , the mind is well-thought, and orderly. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The four of them stood behind Zhou Xing, stopped talking, and quietly watched him do the experiment.

Ten minutes have passed, Zhou Xing confidently pressed the power supply, the power supply was turned on, the circuit board on the test bench was running normally, the indicator light flashed steadily, the hardware design and software programming were perfectly combined, and the experiment was successful.

Zhou Xing picked up the pen and notepad, pointed to the display screen, and began to record the experimental data and check the result data.

After recording the data, Zhou Xing shouted happily: "Uncle Liu, the experiment was successful, and you can proceed to the next item." ”

Zhou Xing turned his head to look for Liu Qiang, only to find that at some point, his father and two strangers were also standing behind him, looking at him with appreciative eyes.

"Xiaoxing, don't be busy with the next experiment, I'll introduce you to two professors, this is Professor Chen, this is Professor Wang, they are invited by your father to teach you other electronic field knowledge, you don't have a lot of questions, now you can 'test' them." It seems that there are two more objects that can throw off the burden, Liu Qiang smiled brightly and happily introduced to Zhou Xing:

Zhou Xing's eyes lit up, he looked at the two professors, introduced himself enthusiastically, and said, "Professor Chen, Professor Wang, hello! My name is Zhou Xing!"

Chen Jianbin glanced at Liu Qiang, looked at Zhou Xing and asked lightly: "Well, the experiment is good, but what knowledge have you learned? The content I teach is not generally difficult, have you read the book on optical engineering?"

"Well, Professor Chen, photoelectric detection, image transmitter information and communication, photonics, optical integration, optoelectronic devices,... I've read a lot of books on optoelectronic engineering. Zhou Xing nodded seriously:

"Yes, then I'll ask you one by one to test your learning foundation. Chen Jianbin nodded and said with a smile:

"Okay, Professor Chen, you ask!" Zhou Xing said without fear:

"A thin magnifying glass with a focal length and a clear aperture of 40mm, the pupil of the observer's eye is 3mm, the eye is located 20mm behind the magnifying glass, and the object is located 35mm in front of the lens.

"This problem is to test the knowledge of diaphragm technology, and the results can be obtained through three steps: 1. Each optical aperture is imaged into the object space, 2. The light is drawn from five points to the edge of the diaphragm image to find out the angle between the light and the optical axis, and 3. The diaphragm corresponding to the smallest angle is the aperture diaphragm. According to the definition of the inlet and the outlet, the result is very easy to find! Professor Chen, the result is ....... Zhou Xing met Chen Jianbin and said calmly:

"You don't have to count the results, you are very good!" Seeing Zhou Xing explain the idea of solving the problem in such detail, Chen Jianbin looked at him differently and interrupted:

"Thank you Professor for the compliment, can I ask you a question?" Zhou Xing asked eagerly:

"Don't worry, Professor Chen has finished the exam, and I will also take the exam for you! Have you also read the book on communication engineering?" Wang Quan suddenly interjected and asked Zhou Xingdao:

"Well, I have learned, Professor Wang, just ask. Zhou Xing looked at Wang Quan, nodded and said:

"What are the secure communication protocols of the WLAN system, and what are the advantages and disadvantages of each?" Wang Quan nodded and asked tentatively:

"WEP has obvious security flaws, WPA uses TKIP protocol encryption, which provides a key reset mechanism, and strengthens the effective length of the key, through these aspects to make up for the WEP protocol, WAPI uses bow key cryptography technology.... Zhou Xing didn't have to think about it, and replied directly:

"Well, the answer is very standard, but it's not enough to just endorse it! I'm asking you a question!" Wang Quan

"Okay, you ask!" Why are you so annoying! Zhou Xing said a little helplessly:

"An 8-channel communication network, each user M city traffic is 0.01Erl, service level B = 0.1, if a dedicated call channel is adopted, how many users can the communication network accommodate?" Wang Quan deliberately made it difficult for Zhou Xing, and chose a more difficult calculation problem:

“B=0.1N=7，… The number of users the system can accommodate: mn 462. Zhou Xing listed the formulas and said the calculation results on the spot without difficulty.

Chen Jianbin and Wang Quan glanced at each other, and they saw a hint of shock in each other's eyes.

Hell, Zhou Xing is still the top student in the college entrance examination at such a young age, has he been studying since he was in his mother's womb?

Just now I watched Zhou Xing independently complete the experiment of single-chip microcomputer development, so he should have a very solid knowledge reserve in this regard, however, they asked him a question that it is possible to answer it with a very solid knowledge base in the two fields of optoelectronic engineering and communication engineering.

"Professor Chen, Professor Wang, how is it, is it okay?" Zhou Wenhai looked at Chen Jianbin and Wang Quan, and asked happily:

"It's a bit unbelievable, but I can't find a reason to oppose it!" Wang Quan smiled bitterly:

"Yes, yes, very much, maybe this is a genius!" Chen Jianbin looked at Zhou Xing with envy and said with a sigh:

"Thank you, Professor Chen's praise, can I ask you a few questions?" Is it okay to ask questions? Zhou Xing thanked Chen Jianbin and couldn't wait to say:

Since you have to collect money from others, you still have to do some work, you only need to teach one student a month, this job is not too simple, Chen Jianbin said indifferently: "If there is any problem, you can just ask!"

"Professor, it's a matter of measuring an instrument measuring a diffraction angle with a width of... Zhou Xing asked unceremoniously:

"Well, that's the question, did you measure it from the angle between the diffraction pole lines? If so, then... Chen Jianbin pondered for a moment and answered Zhou Xing's question:

"I see, Professor, there is another problem, measuring the radius and divergence angle of the laser beam.... ”

"This measurement is a requirement for the width of the slit,...。 ”

"Eun, I know, I have a question. ”

“……。 ”

Soon, in the somewhat dull eyes of everyone, Zhou Xing and Professor Chen fell into the rhythm of one question and one answer, and Zhou Xing showed a sudden realization from time to time, and absorbed the knowledge points pointed out to him by Professor Chen like hunger.

In the blink of an eye, more than ten minutes passed, and Professor Chen Jianbin who solved the difficult problem for Zhou Xing was slightly sweating on his forehead, however, Zhou Xing's questions seemed to be endless, and the questions were one after another.

How much content has this guy learned, and how did he accumulate so many questions?

Wang Quan looked at Chen Jianbin who was tired of coping, and his face couldn't help but change, as if he had a premonition that he was going to end.

I thought that 100,000 yuan could easily be earned into my pocket, but who knew that this was the case, Wang Quan looked at Zhou Wenhai and said resentfully, "Mr. Zhou, you don't make this money well!"

can make Wang Quan say this, this money is too well spent!

Zhou Wenhai laughed, happy, and his original heartache for the high "tutoring fee" disappeared.
