The formation of the plasma channel, conical emission, supercontinuum and third harmonic generation are described.
文章对通道形成的机理、锥角辐射、超连续谱和三次谐波的产生进行了阐述 ,并介绍了目前等离子体通道形成的几种理论模型 。
Radiation angle and central deviation is important parameters of an X-ray directional flaw detector.
辐射角及中心偏移,是定向X射线探伤仪的重要技术指标。
The main differences between radiation angle and coverage angle are given, and the loudspeak′s directivity index is measured by two methods.
笔者对这些变化进行了解读,强调"辐射角"和"覆盖角"的区别,并用2种方法测量了扬声器指向性指数,从而说明新版标准中给出的用覆盖角计算指向性指数的方法简便易用。
