"You little sir, you don't know that it's because a small gun has a different size, so the harm is so great."

Wang Youzhen listened to the fact that he was there to ask for credit for his grandson, and he didn't seem to have any expression, but in fact he was so shocked that he couldn't speak.

He never expected that the eldest disciple Jiao Xu had only learned the knowledge of mathematics, physics and chemistry in junior high school, and invented the vernier caliper and micrometer.

What made him even more incredible was that standardization was invented two hundred years earlier than the West.

Standardization is the basis of all industries.

It is more important for flintlock rifles. After pouring gunpowder and lead bullets into the flintlock rifle, it must be inverted.

The purpose is to completely hold the air in the gun chamber. If the air leaks, the explosive gas produced by the gunpowder will cause silence when it is pushed.

This is a situation that often occurs in bird guns. After igniting the gunpowder, it makes a muffled sound and cannot fire the lead bullet.

The fact that the change brought about by this standardized invention is too huge.

I want Wang Youzhen to see the contributions of his grandson Jiao Xu, so that the young gentleman will pay more attention to Jiao Xu.

Because after standardization, the flintlock rifle will never be in a silence again, and it can be done successfully every time.

If the incident of getting angry every time is successful, if it reaches the ears of the border military officers at Shanhaiguan, they will definitely think that someone is telling the crowd.

Even if you kill me, I won’t believe that the bird gun can fire successfully every time.

But in fact, it can indeed ensure that you get angry every time.

What brings all this change is a standardization.

Wang Youzhen felt so much sigh because he knew the greater significance behind caliber standardization and lead bullet standardization.

Before he returned to the Ming Dynasty, countries had tried their best to formulate 5G standards.

Something has risen to the national level, and it has also made all countries compete for it.

It can be seen that the great significance of formulating standardization.

Each type of firearm, shotgun, sniper rifle, submachine gun, etc. has the most reasonable standard caliber according to factors such as recoil range.

As long as this standard caliber is formulated, any country in the future will have to pay patent fees to China if it produces firearms of this caliber.

The benefits involved are enough to make people feel numb to their scalp.

Wang Youzhen clearly remembers that the Internet fee paid by China to the United States every year has reached a shocking one trillion yuan.

And just today, in this year and sixty years.

Jiao Xu had already invented standardization, two hundred years earlier than Western countries.

Not to mention Wang Youzhen, even if the Chinese nationals from the Chinese Academy of Sciences come together, they will be so shocked that they can't speak because of this incident.

Because of this incident, Wang Youzhen felt even more regretful for the Ming Dynasty and those who had exploded in the late Ming Dynasty.

If it weren't for the invasion of the Qing Tartars, the Ming Dynasty, which had already sprouted the industrial revolution, would have embarked on a brand new path.

I am even more grateful that I have traveled through time and will bring these talents to make up for the biggest regret in history.

After walking the unfinished path of the Ming Dynasty.

Wang Youzhen has not recovered from the shock of standardization yet, and Jiao Xu gave him another surprise, which is also his research results over the past period of time.

Clan Chief Jiao knew why Wang Youzhen came here, so he should come to check out the newly built flintlock rifle.

Clan Chief Jiao walked out of the general to serve as a supervisor and walked into a warehouse in this small yard.

Open the heavy iron chains and take out a new flintlock rifle from the warehouse.

When Clan Chief Jiao saw that Wang Youzhen had not spoken, he couldn't help but feel a little worried.

After he took out this new flintlock rifle, he couldn't help but smile and said: "Mr. I don't know the role of caliber standardization, that's what it should be."

"After all, the young man has never fought with Jiannu in Shanhaiguan."

"Mr. Come and see this. This is also a firearm created by my grandson Jiao Xu."

The leader Jiao was stuck again when he said this. After thinking for a long time, he continued: "It's just a set of service life."

When Wang Youzhen heard a word of service life, he wanted to hug Jiao Xu, who was there and was eating stiffly, and kissed him fiercely.

The most important thing in the manufacturing of modern guns is its service life.

After a firearm is used for a few times, a blow-off will occur.

There are three types of lifespans of firearms, the first is the design lifespan.

Before designing a new firearm, firearm designers hope to achieve the service life.

The second is the maximum life span. There is always a certain gap between the designed things and the final finished products.

The maximum life span is when a firearm is developed and the maximum number of times it will cause a blow-off after it is developed.

The third is the service life, and set a number of times for the firearm to be used. For example, if the firearm is exploded after five hundred times is used.

This service life is generally set to about 400 times, and at most it will not exceed 450 times.

In this way, the biggest harm to the firearm is avoided.

Blasting the chamber.

Long before the explosion, the soldiers had replaced new firearms, which prevented the palms and eyes from being injured due to the explosion.

Wang Youzhen never expected that the eldest disciple Jiao Xu had so many research results during this period.

Not only did we start to standardize firearms, but we also studied the service life.

Wang Youzhen quickly asked: "How many times does this newly built flintlock rifle last?"

Jiao Xu smiled dumbly and said a number: "Two hundred times."

When the head of the Jiao clan saw his grandson Jiao Xu, he simply said something, "It's not painful and it doesn't reflect the hard work in it at all."

He glared at his grandson with a grudge and continued to speak for his grandson with a smile: "You little sir, you don't know, in order to make this service life for more than half a year."

"Jiao Xu has spent so much effort, but he just selected the right steel and tinkered with it thousands of times."

"That's fine, it also involves the pounds of gunpowder and the size of lead bullets."

Speaking of this, the voice of the Clan Jiao clan leader trembled: "Old man, I'm worried that my grandson will be exhausted."

Wang Youzhen himself is a scientist, so why can't he know the hard work of doing experiments? It can almost be said that he has worked hard.

Wang Youzhen took over the flintlock rifle that had designed a service life from the leader Jiao. When he took it, his palms even shook.

Because of the standardized and service life flintlock rifle, it is of too great significance to the Mao Society and even to this era.

It can almost be said to be a milestone in world history.

Because as long as you have this service life, it marks the arrival of something.
