avalanche noise造句

• That is the reason that all over the countries have never stopped researching for mask jamming technology of radar . at present , the mask jamming source mainly comes from the thermal noise and zener avalanche noise of semiconductor devices . but the noise ’ s quality isn ’ t stabile because of the differences of semiconductor devices each other and the changes of exterior conditions
  目前采用的遮盖性干扰的噪声源主要来自半导体器件本身的热噪声或齐纳雪崩噪声,但各器件本身的不一致性和外界条件变化等因素使噪声输出质量不稳定;同时由于此类信号不能再生,不利于科学研究。
