Chapter 855

Dahua's core technology is basically provided by Wu Changqing.

However, the scientific and technological progress in this world is not only promoted by Wu Changqing, others are also working hard.

Dahua's scientific researchers naturally did not have any breakthrough inventions in a short period of time, but they did a lot of improvement work in the original scientific and technological inventions.

Take the steam engine, for example, after Wu Changqing provided some core technologies, the rest of the improvement work was handed over to the staff of the steam unit.

There is a lot of improvement work. There are dozens or hundreds of parts on a steam engine. The improvement of any one part can improve the performance of the steam engine.

Dahua's science and technology star Feng Xianzhong has been devoted to the research of steam engines and has never changed.

The parts that he has improved are not one hundred, but eighty.

Even though Dahua now has various more advanced technologies such as internal combustion engines, he is still researching steam engines.

After all, a single steam engine project will require his life's energy.

The hard work pays off. In April of the sixth year of Yongxing, the steam unit led by Feng Xianzhong produced a steam engine that can generate a pressure of up to 5 MPa.

Compared with the early steam, it is dozens of times higher.

The image point to describe is that the speed of the previous steam engine was only a few dozen per minute.

And now Feng Xianzhong's improved steam engine, the speed has reached 300 per minute, five or six times the previous speed.

With this new steam engine, a ship of the same weight can be propelled two or three times faster.

The increase in power also means that larger ships can be built.

In the past, only ships with a displacement of 5,000 tons could be built, which could not be propelled by steam engines.

Now, Dahua has theoretically possessed the ability to manufacture 10,000-ton ships. If you don't consider the cost performance, install a few more steam engines, and even a ship of 20,000 to 30,000 tons can barely get it out.

The 10,000-ton giant ship is exciting just thinking about it.

In the future, the speed of the train can also be greatly improved, and all kinds of machines using steam can reduce the size, increase the speed and improve the efficiency.

Its progress is comprehensive, and the promotion of industry is also comprehensive, which is of great significance.

After Wu Changqing learned the news, he gave the people in the steam engine research group the honorable title of first-class collective merit.

Some people who have made outstanding contributions have also won many awards, including titles.

And Feng Xianzhong was also promoted from the original marquis to the duke.

This is quite remarkable, one must know that Li Shaobin is just a duke at present.

This award has greatly encouraged Dahua researchers.

More and more people are starting to invest in scientific research. This is the easiest and safest way to get a title.

It's not just the steam engine group who are working hard.

The person in charge of the internal combustion engine project also succeeded in miniaturizing the engine, and then made a motorcycle.

Compared with cars, motorcycles are cheaper and more flexible, and can be shuttled on various trails.

Motorcycles are also an option for some people who can't afford a car.

In previous years, bicycles were fashionable.

But soon, this fashion trend will be led by motorcycles.

For some teenagers, speeding down the road on a motorcycle is the happiest thing. As for safety, some people really don't care.

The people in the rubber project team have also successfully synthesized rubber.

They are forced to make progress. There is too little natural rubber, and the acquisition of Brazilian rubber alone cannot meet Dahua's huge demand.

In this case, the project team tried to cooperate manually according to the properties of rubber.

After many failures, they finally succeeded in their research.

Although the current synthesis technology is still rough and the cost is high.

But this is not a problem. After solving the problem of starting from scratch, the next thing is easy to handle.

As long as we continue to study, we will soon find a way to reduce costs and solve the problem of lack of rubber in Dahua.

With the increasing use of petroleum, Dahua has more and more knowledge about petroleum.

When refining the oil, Dahua also gets a lot of derivatives.

such as asphalt.

Asphalt is the residue after the distillation of crude oil and can also be produced when coal is coked.

The role of asphalt is also very wide, can be used in coatings, plastics, rubber and other fields.

Of course, its main function is to build roads, which is commonly known as asphalt roads.

Compared with the concrete road, the asphalt road is softer, the vehicle is more comfortable and the noise is lower.

The adaptability is also stronger for the road sections where the foundation is not firm enough.

Although it is slightly more expensive than cement roads, those asphalts are not used for road construction, so they can only be thrown away, causing waste.

So, this bitumen is basically used to build roads.

In terms of medical treatment, Dahua has also achieved considerable results.

Wu Changqing came up with a lot of medical theories and even some samples of medicines. Those doctors groped based on these theories, and thus mastered a lot of treatment methods.

Based on the samples of those medicines to infer their ingredients, many advanced medicines have also been successfully imitated.

The development of medicine is also thanks to the development of microscopes.

With the increasing magnification of microscopes, people are more

The better the understanding of bacteria, the better.

Once the pathology is mastered, the treatment will have a clear direction.

All walks of life, in fact, complement each other.

A breakthrough in one industry can often promote the rapid development of another industry.

These are relatively major advances, and those small improvements, enhancements, and inventions are even more numerous.

A more convenient light switch, a better brake, a fan that turns itself are all inventions.

Although the impact of these small inventions on society is not particularly large, they cannot be held in large numbers.

Countless similar little inventions jointly promote the progress of this society.

Wu Changqing did not go out of the palace to take a look at the current Nanjing city, otherwise he would definitely be surprised.

In the current Nanjing, there have been many daily necessities that have been born in later generations.

The whole society presents a very strange scene.

On the one hand, there are people riding in carriages, which feel like they have traveled to the Middle Ages.

On the other hand, there are people who ride bicycles and feel like they have traveled back to the nineteenth century.

There are still people driving cars, and there are street lights on the side of the road.

In the history of the original time and space, there is no place where a scene like Nanjing is now formed.

This kind of scene will make a later generation see it as absurd and awkward.

At that time, for the Nanjing people of this era, they were very used to it.

In their eyes, the development of the world should have been like this.
