After a period of intense preparation, the battle of Mars hitting the earth officially kicked off in May of the fourth year of the establishment of Xingchen Technology.

The first to strike was the Jet Propulsion Laboratory.

As the world's top scientific research institution and a branch of NASA, Jet Propulsion Laboratory's global appeal is unprecedentedly strong.

Overnight, BB, Agricultural, NHK, Bild, The Times, The New York Times, Al Jazeera, Singapore's Straits Times, Facebook, Netflix, Twitter, and almost all the world's mainstream and online media gathered in Los Angeles to cheer for the Jet Propulsion Laboratory.

Unconsciously, the world has changed, and the birth of Xingchen Technology has forced most of the world to unite, forming a dangerous situation of Xingchen Technology VS the whole world.

At this moment, Huaxia, who has a fifteen-hour time difference with Los Angeles, Luo Jia is also nervously watching the situation on the other side of the Pacific Ocean.

Shen Lang held a Huawei brand folding screen mobile phone and read the features of major news media, the words used in these topics were quite unceremonious, trying to elevate the jet propulsion laboratory and belittle Xingchen Technology.

Luo Jia scratched his head, "Enron, do you remember?" When did we begin to be besieged by the world? ”

An Ran was stunned for a moment, and asked rhetorically, "Look at what I said, why haven't we been besieged by the West?" Ever since the company was founded, they've treated us like a thorn in the side. ”

Luo Jia shook his head, "It's not so exaggerated, in the past, at least some Western media would stand up and say two fair words, as for the academic community, we are often praised, and they want to give us awards, but we have all refused." ”

"April 13th." At this time, Shen Lang suddenly said.

Luo Jia and An Ran were both stunned and looked at him puzzled.

Shen Lang said lightly, "The teacher asked, when did we start to be besieged by the world, I think, it started on April 13 last year. ”

Luo Jia's eyes lit up, "Interesting, tell me your reasons." ”

Shen Lang raised his head and said unhurriedly: "On April 13 last year, our first Carmen vortex Street power generation array was officially launched near the Donghai Bridge, causing a global shock. ”

"I wrote a crawler and made statistics on the global news content on April 13 and the week after that, and the results are as follows."

"Seventy-six percent of the news media in North America use more than three negative terms such as hegemony, threat, and instability in their reports."

"The European region is slightly better, with a negative index of 62.83 percent, but Europe shows huge differences due to geographical reasons, for example, Serbia, which is located in the Balkans, has not shown much hostility from the media or the people, and even thinks that it is a good thing for China to master new energy technology."

"But at the same time, the negative index of western and central European countries has even reached 80 percent, which is higher than that of North America, and in Germany, more than 86 percent of the German media have shown great anxiety and distrust for China's mastery of new energy technology."

An Ran couldn't believe his ears, he grabbed Shen Lang's shoulder, "Last April? You didn't come to Etoile University at that time. ”

Shen Lang nodded, and said with a heartfelt voice: "But I was already admitted at that time, so I studied a little in my spare time, after all, I don't want to know nothing about the place where I study and live in the future." ”

"What about a negative index?" Luo Jia asked.

Shen Lang explained, "I designed a statistical model, first by screening keywords, to determine whether a news article tends to be positive or negative, and then to score the tendency, and finally accumulate and sum all the scores, and then add historical events to compare, you can get a relatively scientific public opinion index." ”

"If public opinion is positive, it is called a positive index, and if it is negative, it is a negative index, and the higher the index, the greater the influence."

This demon...

An Ran and Luo Jia glanced at each other, both of them were quite speechless, you know, Shen Lang is only twelve years old this year.

Los Angeles Exhibition Hall, Press Hall.

The staff set up tables and chairs, set up the lights, and the beautiful host, with long chestnut hair, and Dr. Denapp from the Jet Propulsion Laboratory, sat side by side.

Offstage, journalists from all over the world, Dr. Dennap will be here to answer the most important questions of the media at the moment.

"Dr. Denapp, I'm a journalist from the Financial Times of London." The bespectacled lady stood up and asked in a standard London accent, "I would like to ask, why are ultrasonic motors also called space motors?" What are the advantages of ultrasonic motors compared to traditional motors? ”

Dr. Denapp smiled, "From a scientific point of view, there is no such thing as a space motor in the world, whether it is a traditional magnetic motor or a new generation of ultrasonic motors, it can be used in space. ”

"But everyone knows very well that the cost of carrying out a space launch is very high, so the ultrasonic motor with smaller size, higher precision and more variable shape is obviously more in line with the requirements of space use, and because the ultrasonic motor uses voltage to generate torque, it will never be subject to electromagnetic interference, which is very important for space operations."

After a pause, Dr. Denapp said, "As for the advantages of ultrasonic motors, there are too many, but first I want to clear up a misunderstanding. ”

"The ultrasonic motor has nothing to do with sound, nor does it use the acoustic principle to generate torque, but it happens to have the same working frequency as the ultrasonic frequency, so it was given the name of ultrasonic motor by scientists."

"So it's more likely to be called an overclocking motor?" There were reporters in the audience shouting.

Dr. Denapp nodded slightly, "You're right, ultrasonic motors are a new generation of motors with incredible super high frequencies. ”

"So who is more powerful than the ultrasonic motor and the permanent magnet vector motor of Xingchen Technology?" Another reporter asked a question, his eyes glinting with excitement.

Dr. Denapp looked around the audience, the flashing eyes of the reporters, and the cameras pointed at him one by one, undoubtedly indicating that these people actually didn't care about the technical details at all, they only wanted to know one thing, who was better than the ultrasonic motor in the jet propulsion laboratory and the permanent magnet vector motor of Xingchen Technology.

Denapp straightened his back and said, "I can't answer this question. ”

"Why?" The reporters asked puzzled.

"It's like asking me who is faster in the train or the horse-drawn carriage, and it's a very stupid question, not at all a technology of the same era, and shouldn't be compared together." ”

"Although I also admit that the permanent magnet vector motor of Xingchen Technology has reached the apex that magnetic motors can reach, it is still a magnetic motor after all, which is like the most luxurious four-wheeled carriage in the world, no matter how exquisite, beautiful, and clever the craftsmanship is, it cannot be compared with a train."

"Do you understand? They are not products of an era, like kites and airplanes, canoes and steel battleships, abacus and computers, handwritten letters and e-mails, the gap is not big, but a whole generation. ”

Hahahaha~

The reporters burst into laughter, and all they were waiting for was this sentence, and countless writers quickly sent out live stories, using a lot of sensational headlines.

"Permanent magnet vector motors have been criticized as primitive tools!"

"Leading an era, Xingchen Technology's motor has just fallen behind on the market!"

"The Jet Propulsion Laboratory lives up to expectations, and the permanent magnet vector motor is about to enter the garbage heap of history!"

It turns out that journalists are always a group of people who are afraid of the world, they don't care about technical details, they just want to make big news.

Denapp said that ultrasonic motors were a full generation ahead of permanent magnet vector motors, and reporters took the opportunity to make a big fuss.

"Hello Dr. Denapp, I'm a reporter for the Washington Post." At this time, a man in a gray suit stood up, "It is said that Xingchen Technology Group is also preparing ultrasonic motor products, I don't know who is better between the products of the Jet Propulsion Laboratory and the products of Xingchen Technology?" ”

Swish~

It was a crucial question, and the room fell silent as everyone waited attentively for Dr. Dennap's answer.
