The origin of "invisibility" and the origin and use of party emblem

The origin and use of "invisibility" The subtitle of the book "The Collapse of Bureaucratic State" recently written by Liu Panshi, the former director-general of the Liberal Democratic Party of Japan, is "What is the invisibility complex nested in the center of Japan", which is said to mean that the government and people's power with the privileged class and bureaucrats sticking to the rights and interests alliance as the core hides people's eyes and ears. However, the daily use of the military term "invisibility" is somewhat surprising. "Invisibility" comes from the noun "stealth" in English. The main meaning of "stealing" is not only "stealing", but also "quietly" and "furtively", among which stealing home plate in baseball is the most appropriate. But as a military term, it refers to "radar is difficult to capture" and "penetrating radar network".

The use of "invisibility" can be traced back to the late 1970s, and it first appeared in US military magazines. At that time, the manifestations were "stealth bomber" and "stealth plan", and the discussion about "stealth" became a hot topic among relevant people. However, it was then US Secretary of Defense Brown who officially announced the "stealth plan". He said at the press conference held on August 22nd 1980 that "the United States has developed an aircraft that cannot be captured by radar". He also revealed that in fact, a long time ago, the US Department of Defense began to develop the radar reflection cross-sectional area of aircraft and cruise missiles as "intrusion technology", and the result was "stealth plan". It is not difficult to see that Brown announced that the B-2 bomber and the F- 1 17 stealth fighter were developed by using the B- 1 bomber to reduce the radar cross-sectional area, and they have combat capability.

"Stealth" is technically composed of three elements. One is to use an electric wave absorber. The electromagnetic wave absorber completely converts the incident electromagnetic wave into heat energy and does not radiate it. Adding paint or pasting flaky objects on the surface of the structure; The second is the technology of preventing electric wave reflection, in other words, the material with poor current is used as the strength component of the aircraft. The things reinforced by epoxy resin such as boron, carbon fiber and polyamide were the early representative materials, and then the radio wave absorber composite material with precisely controlled thickness formed by carbon fiber appeared. The third is to avoid radar wave technology. Airplanes and ships are designed to avoid radar waves. Looking at the plane angle of F- 1 17, we can know that the surface structure of B- 1 is mostly curved, with a small radar cross-sectional area, and then a flatter shape with a large peak reflection but a small reflection range. Due to the appearance of F- 1 17, the word "stealth" began to expand from electronic warfare stakeholders to the outside and appeared as a common term.

There is a large desert in the north of Tucson, Arizona, USA, and an airplane museum is built in the desert. At the entrance of the museum, the cactus symbolizing Arizona lined up to welcome guests. Each cactus is hung with an introduction card, and the word "variety" on each card says "big". Can "big" be the age of a tree? From the age of 200 years, the length of more than ten meters to the miniature cactus, the species are complete and neatly arranged, but one section is empty on the way. "Is it dead?" While I was wondering, I saw the sign impressively saying "Variety: Invisible Cactus".

The fierce fighting in Kappa

Pan keqin

On August 5, 1944, the troops stationed in India captured Myitkyina, a major town in northern Myanmar, and completed the first stage of the counterattack mission. During my break in Myitkyina, I was transferred to the 89th Regiment of the new 30th Division as platoon leader.

The war in Myitkyina has been extinguished, but the Irrawaddy River is still busy, motorboats shuttle back and forth, and engineers are rushing to build the bridge across the river day and night. Soon, Ba Maw's assault war started.

1944, 10 in June, all the new 38th divisions crossed the river and moved forward with the army to become the first-line corps. In order to get through the China-India highway as soon as possible, the new 30 th Division crossed the steep mountains and advanced to Nankan, fighting fiercely with the peripheral enemies.

New Year's Day came quietly at 1945. The new 30 th Division 89 th Regiment emerged from the mountain forest in the west of Nankan and pushed it to the side of Ruili River to cross the river in the rain, which tightly blocked the gap in Nankan.

1 month 15, Nankan was filled with fog, and the troops passing through the camp rushed down like a flood, and Nankan was quickly liberated.

1 28th is the 3rd anniversary of 19 Battle between Shanghai and Shanghai/kloc-0. The Western Yunnan Expeditionary Force and the troops stationed in India chose this date to meet at Mangya, which is less than 10 from the border town of Wan Ding, Yunnan. Since then, the China-India Highway has opened an international route from Redo to Kunming, India, with a total length of 1566 km.

The salute to greet the troops just sounded, and the 89th Regiment of the new 30th Division was in action. Raiders raided Kappa, just north of Mangya. Kappa is an important stronghold leading to Lashio. The remnants of the 56th, 2nd, 49th and18th Japanese divisions all retreated here, ready to fight back. According to the deployment, my third battalion attacked the first line troops in Kappa, and my seventh company attacked the right wing.

February 4th is an unforgettable day. Before dawn, the whole company had dinner in advance, and the company commander ordered the first and second platoon to attack, and the third platoon was the reserve team, heading for a pine forest outside. It was sunny that day and we arrived at the scheduled place at noon. The enemy deployed fire on the ridge line to stop our army from advancing.

The encounter in Kappa began, and even the commander set up a telephone at the foot of the hill to direct the battle. But our army is in the position of attacking from behind, and the terrain is very unfavorable. The first platoon charged, but they were all repelled. Yin Lianchang is a hothead. When the first platoon saw that he couldn't get up, they immediately transferred heavy machine guns to cover the second platoon's storm. Gunfire was loud and shouts were loud, but until dusk, there was still no progress. The wounded evacuated their positions in batches, and the two platoon leaders also lost contact and their whereabouts were unknown.

This time, the cooking soldiers brought dinner. I asked the messenger to deliver food to the wounded. The company commander and I squatted under the big tree for dinner. His eyes were bloodshot and his face was ugly. He is holding a steamed bread, and his hands are shaking. I couldn't eat this meal, so I begged the company commander: "company commander, let's go to the third row!" " "He sighed and replied," all right. "

I raised my submachine gun, ordered the assembly to prepare for the battle, and I gave instructions to the four squad leaders.

It was getting dark and the forest became blurred. Our party groped carefully, and when we heard the guns in the distance, we knew we had come to the enemy's rear. My hands felt cold, my feet slipped, and I fell into a big pit with thatch on my head. Then the messenger came to report that Class Seven had successfully reached the roadside. I ordered Class Seven to move on and quickly occupy the commanding heights for vigilance. Unexpectedly, as soon as Class Seven jumped across the road, the enemy's machine gun rang loudly, and Class Eight immediately covered with fire and retreated to its original position. I ordered two classes to build fortifications on the left and block the road with fire. At this point, the enemy knew that his retreat had been blocked, so he ordered heavy machine guns to shoot at my position desperately, which was very fierce. I transferred Class 9 to deal with the enemy. In an instant, the sound of machine guns and the explosion of grenades shook the silent mountain forest and a battle began.

I braved the bullets to the position of class seven, with many craters and smoke everywhere. The seven squad leaders and the machine gunners were covered in blood and shot at the enemy with hot machine guns. The casualties of these people are too heavy. The wounded were lying on the ground. A young man threw himself on the ground. The moon shone on his pale face and his mouth was bleeding. I used to pick him up, only to find that there was a big hole in his chest, and plasma suddenly poured out like burst water. My sleeves are all wet, and the grass on the ground is covered with the blood of soldiers. He died when his blood ran out.

I ran frantically to the machine gun position and shouted, "Bring the Grenade launcher!" " "Hold your breath, aim at the enemy's heavy machine gun fire and launch grenades. A red light pierced the night sky and sprayed at the man-eating black hole. Damn it, that guy is silent anymore!

The enemy's heavy machine gun position was destroyed, and three classes rushed across the road and built fortifications on the hillside to prepare for another battle. I ran to the front right to observe the enemy's situation, and as a result, there was a Japanese soldier squatting under the tree, which was completely unexpected. I was caught off guard and started shooting with a submachine gun, but the bolt got stuck. He stood up and rushed at me with a bayonet rifle. I quickly hid, and when he turned around, I had pulled out the broadsword at my waist and cut it at him. He failed in three sprints and was exhausted. I saw him panting, and a pair of dead fish eyes glared at me and hissed loudly, "Ah! ..... "Stumbling to sprint, at this critical juncture, I cut him open with a knife, and the ruthless blade split into his face at the same time. His face was covered with blood, and the gun fell from his hand and fell to the ground and died.

Yin Lianchang has reached the front line. We * * * are studying the operational deployment and think that this hill must be held. But at present, the strength is thin, and the enemy is going to fight back, which is bound to be irresistible. There are too many dead ends ahead, and direct weapons can't play a role. The company commander decided to go back and adjust mortars to help.

As expected, after the company commander left, the enemy began to fight back. 10, a group of death squads with explosive charges and bright bayonets crawled towards our position step by step. I was ordering all classes to concentrate on grenades, but when the enemy shouted, grenades fell on the ground like hail, and suddenly the ground broke and grenades blossomed everywhere on this hill. I look covered in dust and mud. I opened my eyes and there were three grenades that were about to explode, smoking. I grabbed two hand grenades and threw them at the shadows. Bang, the devil fell to the ground. At the same time, another Grenade exploded in front of my right, and with a bang, I couldn't see anything, my ears were buzzing and my mouth was open ... but my mind seemed to see the world where the enemy even shouted and killed, which was no good! I forgot my life and shouted, "Brothers, fight!" Grenades, machine guns and grenade launchers sounded together, and all the charged enemies were finally wiped out.

In this battle, our platoon suffered more than half of the casualties, leaving only 2 1 person in the whole platoon of 52 people. I don't know how long it took, but I began to feel pain in my right arm. When I touched it, it turned out that my right arm was bleeding constantly. My brothers advised me to go down and have a rest. No, I can't leave. I ordered the platoon leader to lead the brothers to hold their positions and quickly enter the artillery positions, ready to attack the enemy.

The company commander saw me like this on the ground and ordered the corpsman to give first aid. When dressing the wound, he found that there was shrapnel in it, so he ordered me to get off the line of fire and send it to the operating room for surgery. By this time, I had fainted. When I woke up and learned that the company commander had been killed, I couldn't help crying.

This day has really changed a lot, how fast you are going. Later, I was taken by helicopter from the front line to Magrida rear hospital for treatment.

1945 captured Kappa on February 8, and the fierce battle lasted for 4 days. According to Zhongjing Daily, our company, the new army, made outstanding achievements in the battle outside Kappa. I annihilated more than 50 people and killed the Japanese squadron leader 1 and the Japanese squad leader 1.
