"Mentor, I'm ......" In front of the mentor, Dong Jun, who had been trained once just now, was a little incoherent.

Professor Yu glared at him, after all, he was a cultivated person, even if he was angry, he would not make a cursing move.

"Do you remember the rules and regulations of the laboratory? These instruments are all high-tech from abroad, and if something goes wrong, they have to be responsible. Seeing that his students lowered their heads and did not speak, Professor Yu's tone was a little calmer.

In fact, he is not wrong in what he said, the more sophisticated the instrument, especially the scientific research instrument, the more demanding the conditions, and some need to establish a special laboratory in order to eliminate external interference. For example, in the field of medicine and biochemistry, when it comes to a series of problems such as viruses and experimental conditions, it is necessary to wear not only laboratory coats, but also special biochemical clothing, protective clothing, and so on.

The easing of Dong Jun's attitude does not mean that Lu Tao, a student who obviously looks stunned, will give a good face.

"You, which college?" looked at Lu Tao, and Professor Yu asked dissatisfiedly.

"School of Chemical Engineering, junior. Lu Tao replied honestly.

"What are you doing here? If you want to do an experiment with your brother, you can only get the teacher's permission. "In fact, students from various teachers in the university sometimes encounter problems, and they do go to the laboratories of other topics to do it, but they usually need to discuss with the teachers first, and some of the other research groups have to charge for the loss of instrument consumables.

Dong Jun looked at Lu Tao with some embarrassment, the mentor has not been in a good mood these days due to the problems of the project, and everyone has suffered, and he has been criticized, but he didn't expect Lu Tao to come over to deliver the goods today, and he just hit this muzzle.

At this time, he still didn't open his mouth to explain, but he really couldn't say it.

Summoning up the courage to look at his stern mentor, Dong Jun explained, "Teacher Yu, that, yes...... I asked Senior Brother Lu to come over and help take a look at this pour point detector. ”

Usually, most of the problems encountered in the experiment are solved by the students themselves, even if the instrument is broken, usually the user first communicates with the manufacturer and then reports to the teacher.

"He's a junior in college, what's the use of looking for him to see the instrument?" Professor Yu snorted coldly and walked straight to the instrument.

"It's only been a year and a half since I bought this instrument, what's the problem now?" Professor Yu is still quite confident in the quality of German products, thinking that either the operation is not standardized, or the experimental conditions are not suitable.

"The results made step by step according to the information in the literature are always not correct. Dong Jun said cautiously.

"If there is a problem, you have to find a way to solve it, find a student to do something, and tell the manufacturer when you have it, and see what it says. Professor Yu walked to the front of the instrument, looked at it, and didn't see any reason, so he said directly.

"I have asked the manufacturer, and they said that the machine has to be inspected on site, and it will take about a week to arrange for the engineer to come, and the price is ...... The price is at least 5000. ”

"What?5000?" Professor Yu's eyes widened when he heard the price. Even if he spends a lot of money on scientific research a year, he has a lot of places to spend money. Besides, it's just to invite the manufacturer's engineer to come and take a look, and in his mind, where to get so much money, isn't this taking himself as a big wrong.

"Didn't you just buy it for a year and a half? When you signed the contract, it was said that it would be a few years after sale?" Professor Yu lowered his head and pondered for a moment, then raised his head and asked.

"I've seen it all here, and the after-sales warranty is one year. ”

"These gringos, they really know how to count. When Professor Yu heard this, he whispered.

"Well, even if that's the case, you can't just bring people from other research groups in the future. ”

Dong Jun nodded.

Professor Yu thought for a while and continued: "Well, let's explore the experimental conditions first to see if it is an operational problem, and if it doesn't work at that time, I can only invite the engineer to come over." ”

In his eyes, he didn't take Lu Tao, a junior student, in his eyes anyway, and the student knew this instrument? Isn't that a joke? When he bought it, the manufacturer sent someone to train him in the operation steps.

As for repair, I am not a manufacturer's technology, and I am not an expert in instruments, so how can I understand? If you say a simple laboratory instrument, you know the principle or something, you can probably find out the reason, but this kind of hundreds of thousands of instruments have a problem, and he has no solution, which can not be seen by the naked eye alone, or people can sell it so expensive?

"Teacher, Lu Tao is usually familiar with instrument manufacturers, so I brought him over to see if there could be other solutions. ”

Dong Jun, who felt that he had been wronged by the teacher, reminded him on the side, before he only said that Lu Tao was a student, but he didn't say that he understood instruments.

Professor Yu paused, although his students explained so, but he was a teacher, so he would not apologize to the students, and said a soft 'um' in his nose, and asked Lu Tao, "Are you familiar with the manufacturer here?"

Lu Tao nodded and replied: "Mr. Yu, I am mainly working part-time to make some instruments and laboratory consumables, so I usually have contact with most manufacturers, and I still understand some instruments." ”

He is not stupid enough to hold a grudge just because of such a trivial matter, and play a so-called drama of pretending to slap his face.

After all, he is a tutor, he has strength in scientific research, and he is only a junior in college, I believe that at least ninety-nine out of a hundred people will think that they don't understand this instrument, and it is no wonder that Professor Yu is like this. What's more, if he wants to continue this business in school, it would be too stupid to offend a tutor who can speak well in the academy because of this little thing.

Many people always have a resentful attitude that they will be slapped in the face immediately after being said a few words, in fact, think about it calmly, where in the world are there so many boring people who come to slap you in the face all day long.

There is probably a reason why people can say that. In many cases, once things are thought through, it may not be like that, and maybe the enemies at the beginning will become their friends later.

Lu Tao once heard someone say such a thing. said that there was a salesperson who had been going to meet an academic bull and sell him products, but every time people refused, and later he was annoyed by his sales, and directly said not to bother him again.

Rao is so, that sale is still the same as always, and does not give up. It's just that the frequency has become a little less, and I have also changed my way of doing things, that is, I nodded after encountering it, said a simple greeting, and never mentioned the promotion and products.

Who knew that after more than half a year, the academic bull was moved by his perseverance, and even the millions of purchases in the back laboratory were directly handed over to him for the previous sales that seemed a little annoying.

The so-called upper-class people, people helping people, middle-level people, people comparing people, lower-class people, and people as a whole actually say this truth.

If you can't control even a trace of your anger, what else can you say?

Some people may say that why are you so temperamentless, you don't know how to be angry and angry, happy and vengeful?

In this regard, Lu Tao just wanted to say that harmony can make money, and you have to rely on these teachers to make money in the future. Wouldn't it be more refreshing to earn his money from someone who originally looked down on him than to slap him in the face?

Professor Yu looked at him, adhering to the attitude of a dead horse as a live horse doctor, and said: "Then you can take a look again, now the manufacturer is also troublesome to repair, and there are thousands of repairs at every turn. “

When Lu Tao heard this, he looked at Dong Jun, and then smiled at Professor Yu and replied, "Okay, if you get it right, Teacher Yu will have to take care of my business in the future." ”
