Chapter 291 (2/2)
”I have been doing this work all the time. I know better than you Team leader, you see you are all busy all night. Take a rest now. ”
”I am on a break when the new man just came?”
When they are fighting for nothing.
Li Zheng has already taken a chair to sit at the desk, and he should be steady in setting up the manuscript, notebook and calculator.
I didn't have time to find something to learn. This information hit me.
It must not be learned to die!
……
Li Zheng's study is full of 40 minutes.
When he returned to find hezhongrui, he just finished the document for Lin Passover Jing and was about to narrow down in the lounge.
When Li Zheng came over, he Zhongrui was tired and smiled: ”I said it, I can't understand it In this way, I have explained the document to Xiao Lin. you should organize with her first and get familiar with the work. ”
”No, I understand it basically.” Li Zheng waved expectantly, ”come and come, and have a big job.”
“？？？” He Zhongrui was stunned and looked at the eye table again. ”You Just looking at two pages, I feel like I'm ok? ”
”I still saw a lot.” Li Zheng explained with a hard head, ”just a lot of knowledge I have been in touch with before, and I can jump past.”
”No...” He Zhongrui grabs his scalp and says, ”space engine knowledge, you teach me where to contact?”
Li Zheng is not good to say anything, only raising eyebrows and saying: ”good brother, come to some big work first try it.”
He Zhongrui saw his face frolicking and smiling, and he was a little impatient: ”Li Zheng, how much can I do so much, so you are in this situation, can I give you work?”
”Ah, this...” Li Zheng is in a dilemma.
He is not to blame him Zhongrui, and it is true that he has problems in the words that are reasoned.But how can this be explained
At this time, a cold smile came out of the blue.
”Test him.” Lin Yue sat in front of the computer, scanning the document and said, ”he will not be allowed to take any examination.”
”Wonderful.” Li Zheng stared at him again, and then he pointed out, ”test me.”
“……” He Zhongrui is lazy to waste this time naturally, let alone being sleepy. But considering the complexity of these two identities, he nodded. ”Li Zheng, the work is really tight now. If you can't answer it, either go back to study, or do the document work with Xiao Lin, at least not to increase our burden.”
”Sure.” Li Zheng's look is also gradually grim, ”teacher he asked directly, save time.”
”I'm in a dilemma.” The forest Passover stood by and coaxed.
”Ha ha...” He Zhongrui said with a bitter smile, ”I really want to give you face But since Xiao Lin said that I'm not welcome. ”
”Please...”
He Zhongrui knead his forehead and thought about it.
Several people in the office were also frantically stealing.
It's just high school level, and it's just a field of master's degree.
It's time to show dignity, leader.
Let Lin Passover Jing also take a good look at the level of the test group.
The five words ”aerospace engineer” are not in white.
As for he Zhongrui, although he was asked to have a difficult problem, he was a doctor level existence after all. On the first hand, he would not answer the delicate problems that the other party would not answer, and it is inevitable that some bullying the younger generation.
On the other hand, he also wanted to take the opportunity to examine the level of Li Zheng.
Therefore, he raised a question of stability.
”Main failure mode of pump engine.”
Li Zheng replied immediately.
”There are 12 summary items in total.”
”1. Joint leakage.”
”2. The initiator is abnormal.”
”3. Hot gas leakage.”
……
”12. Valve is abnormal.”
He Zhongrui was surprised and asked: ”where are the corresponding failure modes?”
”Leakage, corresponding joint, weld, crack, rotating seal...”
……
”Foreign matter, corresponding injector, turbine pump, air flow hole.”
He Zhongrui stared at Li Zheng for a long time, and asked, ”have you ever carried it before?”
Li Zheng had to laugh back.
Who's the fucking one to carry this?
”This one doesn't have to be backed.” ”After a comprehensive understanding of engine structural components, a fault is proposed, and the possible parts can be analyzed naturally, and it is good to understand,” Li explained
Not only is he Zhongrui, even the crazy steal of other people have some looks.
Go to your mother, just to back, understand a hair ah.
They don't know, after two races of tests and a series of thinking tempering Li Zheng
The brain, has become strange.
“……” He Zhongrui asked after a moment of entanglement, ”please list several main fault characteristic value parameters.”
”Flow, pressure thrust, temperature, vibration, speed, stress, torque...”
”Enough.” He Zhongrui raised his hand and said, ”let's simply say how to choose the characteristic value.”
”N feature parameters XK are selected from the existing n feature parameters Xi, and the optimal feature subset is formed in the sense of a certain index function J, and all the possible alternative eigenvalues...”
He Zhongrui interrupted Lizheng again and asked again, ”what is awssa?”
This time, Li Zheng thought for a while and said, ”adaptive weighting and average algorithm, based on engine characteristic signal analysis fault, prediction of one of the algorithms.”
He Zhongrui suddenly returned, took up the paper pen on the desk, and wrote down the formula that the two lines of hair volume was more than 60% and could not be understood.
”Above is the mean of the test parameter, and the variance below. Can we calculate the grabbs statistics?”
”Wait a moment...” Li Zheng took over the pen and thought about it. He wrote down a formula that is simple, but how to send a formula that the talents with a volume of less than 70% could understand. Then he took out the calculator and rubbed his hand and said, ”teacher, you should take a rest first, and I will start to calculate slowly.”
”No more...” He Zhongrui held down Lizheng's arm, and his face showed a kind of innocent suspicion of life. ”Why do you even understand fuzzy mathematics?”
”Just...” Li Zheng hesitated to say, ”I understand it a little.”
“……” He Zhongrui looks at Li Zheng, and it seems that there are three words ”why” in his eyes.
After a long time, he let go and rushed to the back.
”You'll teach him the process of analyzing engine test data.”
“…… Good... ”
He Zhongrui looked at Li Zheng and then looked at the table information, and finally asked, ”why...”All of a sudden, there was another no smile.
”Uhha...” Lin Qijing covered his mouth and said with a smile, ”now I know how difficult I am Who has learned that? ”
