Fang Changxing directly called the leaders of the Physical Education and Research Department of Central University to apply for electronic timing equipment, after all, the manual error is large, and the wind speed cannot be measured.

And the latter was stunned for a moment when he heard Fang Changxing finish talking about the cause and effect, 9.97 seconds?

The 100-meter dash in less than 10 seconds may sound like nothing unusual, but if you want to run in, it's too difficult!

The world has a population of 7.5 billion, but only about 10 people can run in about 10 seconds every year.

Of the more than 220 countries in the world, only 22 countries have ever run the 10-second mark. So far, no woman has been able to run under 10 seconds.

The most important thing is that the vast majority of runners who run 10 seconds in the 100 meters are of West African descent.

At present, there are only more than 100 earthlings who run 10 meters in 10 seconds, but more than 500 people have been in space!

It is not too much to say that 100 meters in 10 seconds is more difficult than going into space.

At present, there are no 100 players in China who can run into 10 seconds, that is, "Flying Man" Liu Xiang, who can't run 10 seconds in the 100-meter sprint.

How is it possible for a student who is not a track and field major and has not undergone professional training?

Therefore, the first reaction of the leaders of the teaching and research department was that Fang Changxing was joking.

A little displeased: "Xiao Fang, this April Fool's Day has passed, it's not appropriate to make this kind of joke!"

Fang Changxing hurriedly said: "Leader, I'm really not joking with you, Su Zhensheng, you know, the 100-meter sprint champion of the National University Games, I just measured him to be 10.51 seconds." And Lu Yan's advantage is quite obvious, even if there is some manual error on my side, but I believe it will not be too big, I dare to guarantee the ticket, he can definitely run within 10 seconds. ”

The leaders of the Physical Education and Research Department heard Fang Changxing say this, and then thought of his past style, and felt that the authenticity was not small.

I think that if the central university can really produce a 100-meter dash runner who can win glory for the country in the summer world championships, they will also have a share of credit!

I was a little excited when I thought of this, because in a comprehensive university like Central University, which focuses on academic research, it is not easy for those who engage in sports to make some achievements.

Immediately said: "Okay, since you dare to guarantee the ticket, then our teaching and research department will not be busy with anything else in the afternoon, and take a good look at the student you said!"

After hanging up the phone, more than a dozen teachers of the track and field group, and even national coaches, brought electronic timing equipment.

In this era, sprint timing equipment is very advanced and complex.

Once the runner has their feet on the starter and is ready to start, the timing referee pulls the trigger of the starting pistol, sending electricity through the copper wire to the starter and the separate chronograph station.

The current activates the quartz crystal oscillator on the timette, while the sound of the starting pistol is amplified by the speakers of each runner's starting gear, so that all competitors can hear the starting pistol at the same time, achieving a truly fair race.

At the other end of the track, the laser signal travels from one end of the finish line to the other, and the light sensor at the other end receives the beam signal from the laser.

When a competitor crosses the finish line and the beam is blocked, the electronic eye immediately sends a signal to the timing station to record the runner's race time.

At the same time, a high-speed digital video camera mounted parallel to the finish line scans the image into a narrow profile at an astonishing speed of 2,000 times per second. As each runner crosses the finish line, the camera sends an electronic signal from the body part that first touches the finish line to the chronograph to record their race time.

There are a bunch of steps to follow, in short, to make the observed and recorded data more accurate.

In comparison, just relying on Fang Changxing to wave his hand just now and press the stopwatch record is simply unprofessional to the extreme.

Fortunately, Su Zhensheng is not an idle person, although he is not the best 100-meter sprint champion in the National University Games, but after all, his strength is there.

Lu Yan was able to outrun this, which finally gave Fang Changxing some confidence.

Otherwise, he would never have believed that Lu Yan could run for more than nine seconds.

During the short break, several leaders of the Physical Education and Research Department of the Central University, together with more than ten teachers from the track and field group, brought a bunch of equipment to the sports field.

Some people go to install starters, high-speed cameras, and some measure wind speed.

In international competitions, in track races of 200 meters and below 200 meters, as well as long jump and triple jump, the average wind speed of more than 2 meters per second when downwind is valid but not listed as any record.

Since it depends on Lu Yan's real strength, the wind speed also needs to be considered.

"0.9 meters per second, leader!" reported the teacher who measured the wind speed.

Xie Guotian, deputy minister of the Ministry of Education and Research, is not yet fifty years old, he is in the prime of life, and he looks very bold, and said: "Okay, hurry up and get the timing device ready, and students can watch it, but they can't be so messy all the time, and the impact is not good!"

The main reason is that Lu Yan and Su Zhensheng are both celebrities in the school, which is equivalent to two traffic stars facing each other, for many college students who feel bored every day, such an activity is too exciting.

One by one, in the class group, fellow group, roommate group, call friends and companions!

"Shocking news, Lu Yiyi and Su Zhensheng faced off in the 100-meter sprint at the Xuanwu Stadium, the leaders of the Physical Education and Research Department are here, come and see, students!"

"Damn, is it really fake?"

"This is fake news, Lu Yan is practicing martial arts, Su Zhensheng is practicing sprinting and kicking, they don't have any intersection, they are better than sprinting, and they also recruited physical education teachers, it's too!"

"For two such excellent men to face each other, it must be because of women, is it because of Ruan Xiaoxiao?"

"I heard that Su Zhensheng's girlfriend Ye Tingcheng admires Lu Yan very much, and the two of them have quarreled because of Lu Yan, it must be because of Ye Tingcheng!"

"Damn, isn't it, the news is so exciting!"

"But why do you want to sprint?"

"Because Su Zhensheng is the best at this, better than money, it must not be as much as Lu Yan. In terms of appearance, the two are comparable. If you want to talk about force, it must be Lu Yan to win, it can't be compared to football, right?"

"I think it's okay, Su Zhensheng has a school team, but Lu Yan has money, please ask a few foreign aids, play in our school, it's exciting to think about it!"

On the campus of Central University, many students went to Xuanwu Stadium while guessing nonsense in the QQ group on their mobile phones.

Ruan Xiaoxiao, who was originally decorating her own company, also received a call from Qi Xueli.

said that Lu Yan was sprinting with Su Zhensheng at school, and now everyone is passing it on. The two competed because of a woman, and I don't know if it was because of her Ruan Xiaoxiao or Su Zhensheng's girlfriend Ye Chengcheng.

When Ruan Xiaoxiao heard the news, her first reaction was stunned.

Her boyfriend competed with someone else's 100-meter sprint, and she actually found out after being reminded by her roommate that this person's heart is too big, right?
