In the afternoon of the second day, the Building Disaster Prevention Laboratory of Jitong University.

"Professor Qian, Professor Qian?"

"Ah, Xiao Li, thank you, thank you, thank you for bringing us these good things......"

Li Huayong smiled secretly in his heart, he had been here for a while, and the purpose was naturally to send the materials that Lin Wei had brought back here. When Lao Qian first saw those things, to be honest, he didn't really care much at first. Just waited for him to open a magazine casually--- it was actually a journal of the University of Stuttgart, Germany, the original German edition, but here is Jitong University, which has a deep relationship with Germany, so it is not surprising that Lao Qian can read it.

After Lao Qian saw this, his attributes as a science and engineering technical man were directly reflected, and his eyes barely left the magazine, and he directly hung Li Huayong there, and he didn't react until Li Huayong called him himself.

"It's just a gesture, Professor Qian, don't be too polite. ”

"Hehe, I forgot Xiao Li, you are still a capitalist, but your effort has helped us a lot, so ...... other materials" Lao Qian pointed to the big box brought by Li Huayong with his hand:

"It's all about Carmen Vortex Street?"

Li Huayong smiled: "I don't know the specifics, you see that these are all some foreign language materials, where can I understand so much, I just asked a friend to help me collect these materials according to this keyword, whether it is useful or not, then you have to screen it yourself." ”

"Useful and useful, so useful, not to mention anything else, just the paper I just read, this has inspired me a lot, and it will be of great help to our research, Xiao Li, thank you, I believe that with these materials, we will be able to greatly accelerate the speed of tackling key problems this time, and the accuracy and safety will also be greatly improved." ”

Li Huayong accepted this thank you calmly, how important is the issue of "Carmen Vortex Street"? Laymen may not feel it, but in real history, an example of a project in our country may be very illustrative.

It was already after the new century, probably a few years ago, to build a bridge in the form of suspension cable-stayed structure in a certain province in the southeast of our country.

It is said that it is already after the new century, since the repair of the Shencheng Nanpu Bridge, our country has more than 10 years of technology accumulation in this regard, I think there should be no problem.

However, when the bridge was being built, a very serious incident occurred, when the bridge was not fully built and opened to traffic, a thick cable-stayed steel cable with the bowl mouth that carried the weight of the bridge broke.

Like most construction accidents, when this kind of thing happens, the first thing that comes to everyone's mind will not be anything else, it must be whether it is a quality problem? Did the construction party cut corners......

The bridge was no exception, so just after the accident: the project manager of the construction party was controlled, the chief engineer of the project was controlled, and the person in charge of the supervision party was controlled...... Then re-inspect all the materials that have been used or are going to be used to see if there are any problems with the building materials used in that project.

After checking for a long time, strange things appeared, the expert team organized by the state did not find much problem, including the broken steel cable, and after testing, it was found that even it met the design requirements.

So how did this steel cable break? In the end, it was an expert in another field who found the answer, that is, the guys from our national aerospace department, who pointed out a design flaw in the bridge through wind tunnel experiments and proved that the steel cable was actually blown off by the wind.

It seems a bit of a fantasy, right? But it's true.

Because of this design flaw, the direct economic loss of the accident was about 500 million RMB.

Well, in fact, it is a matter of adding a few wind dampers, and the construction cost will not exceed 500,000 yuan.

How can I say it? Use 500,000 yuan to avoid the risk of 500 million, this is the value of the box of materials that Li Huayong gave to Lao Qian.

It is precisely because he knows this value that Li Huayong accepts Lao Qian's thanks calmly. Because he knows that it is impossible for old money to give him money, in this case, he can only listen to old money say a few thanks, and then use it to enhance their friendship with each other.

"Professor Qian, in addition to delivering materials today, I am actually here to say goodbye to you. ”

"Oh, so soon, you're done with everything in the Planning Institute?"

Li Huayong nodded: "It's almost busy now, do you know that Nanjiang is in a hurry......

"Hehe, I know you're a busy person now, so I won't keep you, but you have to hurry up about your graduate school entrance examination......."

After Li Huayong chatted with Lao Qian for a few more words, he said goodbye to the other party. After staying in Shencheng for so long, he really needs to return to Nanjiang now.

With the completion of various preparations, the Nanjiang side has actually started construction on a small scale. And those who are engaged in construction know that during the initial start of construction, there were actually the most things, and now Lao Lu called Li Huayong several times a day to urge Li Huayong to go back.

After saying goodbye to Lao Qian, of course, you have to say goodbye to others. Leaving the laboratory, Li Huayong went to the Planning and Design Institute again, chatted with Lao Dong and them for a while, and then returned to the guest house.

There is now the third batch of people in the guest house who need to say goodbye to Li Huayong, and that is naturally Lei Yutong and her classmates.

"Oh Tongtong, you're getting more and more beautiful now, come, let my sister take a look......"

As soon as he returned to the guest house, Li Huayong saw Lin Wei and Lei Yutong performing sisterhood there.

Seeing Lin Wei hugging Lei Yutong affectionately and talking there, Li Huayong secretly pursed his lips, and said in his heart that his girlfriend is also hypocritical enough, looking at their current intimate appearance, who would have thought that it was because of Lei Yutong yesterday that he had suffered a lot, and the standard was a disaster. This woman is acting, and she is really a good hand.

"Brother Yong. ”

"Brother Yong is back?"

This is the standard room that was opened yesterday, and now Lin Wei's three sisters and brothers are here, and when Li Huayong came in, he was greeted by Lei Yutong's two classmates, Zhao Shujun and Su Qing, so when Li Huayong also came in, the small room seemed a little crowded.

Li Huayong smiled at the two girls first, then turned his head to Lin Kai and asked, "Xiao Kai, have you arranged it for the night?"

After Lin Kai replied "It's arranged", Li Huayong said to Lei Yutong and her two classmates:

"We're leaving tomorrow, thank you for your hospitality during this time, especially Xiao Kai, he said thank you for taking care of him during this time, so just when his sister came over, he wanted to invite everyone to dinner at night, please be sure to appreciate your face." ”

Of course, no one refused, in fact, everyone got along well during this time, and they were already relatively familiar friends, so there was no reason to refuse. After Lei Yutong agreed on behalf of her classmates, everyone turned on the chatting mode.

Since there are mostly women in the room, it is natural that the small talk is dominated by women. During the chat, Li Huayong found an interesting phenomenon, although Lin Lianhua was the most enthusiastic, but the eyes of the crowd were bright, Lei Yutong and even her two classmates felt her hypocrisy, so everyone was a little perfunctory to her, but they were all very interested in Lin Lanhua.

And Lin Lanhua doesn't know what's going on, she usually looks cold and rejects people thousands of miles away, but today she has been wearing a faint smile, especially for Lei Yutong, she seems to be very interested in Lei Yutong, and she has been chatting with Lei Yutong non-stop.

"Tsk, it's eye-catching, it's really eye-catching......"

During this period, Li Huayong didn't say anything, he was mainly looking at the scenery. Lin Hui and Lei Yutong are together, it is indeed a beautiful landscape that can make people forget to speak.

At this time, Li Huayong even thought of the music that might also be present at night, if the three best beauties got together, then I really don't know what kind of beautiful scenery in the sky.

Just when Li Huayong was enjoying the scenery, Lin Kai came over:

"Come, Brother Yong, come out, I'll tell you something. ”

"Oh?"
