In the previous article "P/NP problems in dongye's Novels", I mentioned that dongye's reasoning novels were filmed as the series of Japanese series "probe Galileo". By the way, I would like to gossip about their predecessors, if you haven't read the previous data, stop it now.
The provisionic series later included a set of predicate, which told us that Fukuyama found that the suspect remotely detonated the special shape of the explosive, causing high temperature to melt the front-end metal plate of the explosive, in the course of flight, metal plates are turned into metal jets that look like arrows, thus killing target people remotely.
In the play, this theory was introduced many years ago. Indeed, this is a very old technique, at least one hundred years. Only for civil use, especiallySecret Room perfect murder, Is indeed refreshing.
In physics, the corresponding name is 『Monroe Effect"Or 『Clustering Effect"; Used for weapons, called 『Hollow chargeTechnology:
『
The so-called"Hollow chargeIt refers to the cracking head with a cavity in the warhead.
The front of the warhead containsConical metal hood(Usually copper alloy), the cone mouth toward the front, the cone tip toward the back (as shown in the legend in the second row, the left "cone tip" is the back, the right is the front ), the metal cover is filled with explosives and the front is empty. When a warhead explodes, the metal hood is melted into a high temperatureHigh-speed Liquid Metal Jet,Focus like a lens to the center of the hollow part, Shot at the armor of the enemy tank and rushed out of a hole. This is just as if we used a high-pressure faucet to punch out a hole in the sand.
Its charge is very knowledgeable and must be made into a hollow cylinder with conical holes. The conical charge method concentrates the energy of the explosion in one direction, otherwise it will explode in all directions like the legend in the first row.
It is mainly characterized by the energy of the charge itself, so it is not limited by the initial speed and shooting distance. Therefore, the target human body can be put into a hole like a Samurai knife, and the shape of the hole is like a blade, so the police initially thought it was a knife.

The Monroe effect was discovered by Americans in 1888. However, after being used in weapons practice, I went back to develop the world's first anti-tank-gun grenade, the world's first anti-tank weapon using the principle of hollow charge, after being seen by the British with the naked eye. But at this time, the object that breaks the armor is onlyStrong Air Flow Produced by initiationNo. In 1941, the Swiss sold the technology found by the American Monroe to the Americans, and then the United States developed the mi-type 72mm anti-tank rocket cylinder "bazuka" to show up on the battlefield in North Africa.
Later, some people added a thin layer of metal (such as copper) to the hollow part of the Oracle shell, as demonstrated in the previous article, and the metal melted to a high temperature (more than 1000 ℃) high pressure (more than 1 million pressure) high speed (about 8000 to 9000 per second) Jet Form forward, destroy everything.
