The random error-code is caused from disturb of inside electromagnetism emission.
均匀误码来源于内部信号的同步关系,随机误码来源于设备内部的电磁辐射干扰,突发误码来源于设备的电源或时钟条件被破坏。
The results show that introgen and argon which are as third bodies can get energy from free-atoms and radicals, thus decrease the OH e-mission; but certain argon atoms may increase the OH emission.
本文利用我们研制的棱镜谱仪探测技术研究了氢反应过程OH、O_2的激发辐射特性。
