My biological black technology

From Cheng Xiang's solemn expression, Wen Ziqiang and Zhao Ronghao understood that this man must have discovered something, and it must be something very serious.

How can we not be worried when such an abnormality occurs at such a critical time?

Cheng Xiang's solemn expression alone made the already nervous laboratory even more nervous.

Everyone consciously avoided Cheng Xiang's position when walking around the office, for fear that their careless actions would disturb his thoughts.

"Director Wen, what exactly did Chief Cheng discover?"

"It has been almost six or seven hours since then." Zhao Ronghao glanced at the time on the big screen, took a deep breath and whispered.

"Wait." Wen Ziqiang gritted his teeth and held back one word. They had already taken the initiative to report Cheng Xiang's abnormal situation a few hours ago, and the message above only contained one word, "wait." At this time, no matter how anxious he was, he could not interfere. Calculation work of scientific researchers.

What they can do is maintain a better environment so that Cheng Xiang's calculation work is not disturbed.

"Are you still waiting? In less than two hours, the battle on the front line will begin."

"The superiors have also come here to ask for opinions several times."

"Why don't we go and ask about the general situation first, so that we can feel more confident."

"To be honest, this is the first time I see Chief Cheng so serious."

"I'm anxious." Zhao Ronghao said bluntly.

"Who is not in a hurry?" Wen Ziqiang looked at Cheng Xiang again. The situation is urgent now, but at this time, he needs to stay calm. If Cheng Xiang's important analysis work goes awry because of their interruption, that is Really bad. Too anxious to eat hot tofu, Wen Ziqiang took a deep breath and said, "Keep waiting."

"Eh..." Zhao Ronghao nodded helplessly.

Time flies by like a white horse, and the flow never stops.

At the moment, the target frame marked by the red dotted line on the big screen seems to have passed the orbit of Jupiter, and is only one to two astronomical units away from the orbit of Mars.

In the vast space of the universe, such a distance can be called extremely close.

The nervous palms of Zhao Ronghao and others began to sweat.

"The public communications request has been sent for over thirty minutes."

"Based on the estimated time, the other party should have received the information we sent."

"But so far, there has been no response from them."

"Except for the gradual decrease in speed due to the large changes in the space-time curvature of the planetary system, the course has not changed at all and is still pointing directly in the direction of the earth." Zhao Ronghao looked at the intelligence of the department he was in charge of and selected the important ones for presentation.

Refuse to communicate, which means there is no room for discussion.

The situation is critical and the task is arduous.

At this time, Wen Ziqiang suddenly realized that Cheng Xiang had finally stopped checking his calculations, and immediately walked over in a hurry.

"Chief Cheng." Wen Ziqiang said.

Cheng Xiang nodded, and of course he understood what the two people who came quickly were worried about.

The matter was serious, so Cheng Xiang immediately opened a small window on the big screen to display the abnormality he noticed.

What the screen showed was an abnormal signal that the two of them were very familiar with.

After more than a month, this is the thing that I have seen the most. It is a curve with twists and turns. They are not at the level to analyze so much information from such a curve.

However, this does not affect their familiarity with this curve.

Therefore, seeing Cheng Xiang take out this curve again, he suddenly felt a little confused, "Chief Cheng, is there anything wrong with this abnormal curve?"

Cheng Xiang nodded, "There is a problem, and the problem is very big."

Cheng Xiang's affirmative answer made Wen Ziqiang's heart skip a beat.

Facing everyone's confusion, the curve projected on the big screen changed rapidly. A curve marked with a dotted line was displayed on the big screen at the same time. The two curves, one real and one virtual, had basically the same trajectory, with only a few parts showing subtle differences. difference.

"Did you see it? This solid line is the actual abnormal signal we continue to capture."

"And this dotted line is the predicted trajectory of the supercomputer that is gradually approaching the real trajectory based on continuous enrichment of data training."

"As you can see from the picture, the two are very similar." Cheng Xiang said quickly.

Wen Ziqiang, Zhao Ronghao and others looked at the image and found from the trajectory alone that although the two curves mostly overlap, there are indeed some differences.

"They are very similar." Wen Ziqiang didn't understand the meaning behind the images, but it was still possible to simply look at the geometric meaning.

"So, that's the problem."

"The graphic just now was from seven hours ago."

"Look at this graph now. This is the abnormal signal curve captured six hours ago."

"Do you see the difference?" Cheng Xiang asked.

In the two graphs, the curves generally follow the same direction. The solid lines and dotted lines have undergone some changes, and it seems that the degree of overlap has become higher. However, there are still some places that do not completely overlap.

"There are more overlapping places." Wen Ziqiang said with a frown.

"That's right, there are more overlaps."

"This analysis curve of abnormal signals. As the target continues to approach us, the abnormal signals we receive will become more and more accurate as time goes by. In theory, predictions and reality will become more and more accurate."

"In other words, these two trajectories will gradually overlap and eventually be completely consistent."

"But something unusual happened."

"For everyone's convenience, I have created a Cartesian coordinate system based on the similarity between the model and the actual observed abnormal signals in nearly seven hours."

After that, all the original graphics in the large screen and small window disappeared, replaced by a rectangular coordinate system. In the coordinate system, the positive direction of the X-axis is the distance between the enemy target and the Mars Observatory. The origin is at the maximum value of the X-axis, and beyond Going in the positive direction, the distance becomes smaller. The positive direction of the Y-axis represents the similarity between the two. The higher the similarity, the greater the Y value. The similarity range ranges from zero to one.

Zero, of course, means no similarity at all, and one means 100% similarity.

Such a picture explains everything very clearly. In this similar image, at the origin, the position of X is the position of the enemy target from Mars seven hours ago. At that time, there was already considerable similarity in the Y value. About ninety-five percent.

The entire complete graph is first a long straight line diagonally upward, and then the slope change becomes unstable. It changes from a straight line diagonally upward to a curve that is constantly shaking horizontally, but the Y value does not reach one, and from the overall Looking at it from above, the slope of the entire curve development has been infinitely equal to zero, indicating that the rate of change has no longer changed.

Wen Ziqiang and Wen Ziqiang didn't understand it very well, but after working in these years, they also had experience in these mathematical geometric diagrams. That kind of intuition is just like recognizing characters. You can recognize half of a long character and half of a wide character.

For data graphics like this, you can judge whether the change is smooth. If you encounter non-smooth changes or abrupt changes, there must be something wrong.
