目前,一种新概念隐身技术——“等离子体隐身术”正在秘密开发中。所谓“等离子体隐身术”,是利用等离子体原理来规避探测系统的一种新技术。等离子体亦称“等离子区”,一般指电离的气体,由离子、电子及未经电离的中性粒子所组成;因正负电荷密度几乎相等,故从整体上呈现电中性。不带电的普通气体在受到外界高能作用后(如对气体施加高能粒子轰击、激光照射、气体放电、热致电离等方法),部分原子中的电子吸收的能量超过原子电离能,便脱离原子核的束缚成为自由电子,同时原子因失去电子而成为带正电的离子。这样,原中性气体因电 At present, a new concept of stealth technology - “Plasma Stealth” is under development. The so-called “plasma stealth” is the use of plasma to circumvent the detection system of a new technology. Plasma, also known as “plasma zone”, generally refers to the ionized gas, which consists of ions, electrons and non-ionized neutral particles. Since the positive and negative charge densities are almost the same, they are electrically neutral as a whole. After being exposed to high energy (such as high-energy particle bombardment, laser irradiation, gas discharge, thermal ionization and the like), the uncharged ordinary gas will have its energy absorbed by the electrons in the atoms exceeding the ionization energy of the nucleus Bound to become free electrons, while the atoms lose their electrons and become positively charged ions. In this way, the original neutral gas due to electricity
