The laser output energy, dynamic to static ratio, pulse bandwidth ana spectral line width etc. by Q-switching ware measured and analysed theoretically.
测量了调q后激光输出的能量、动静比、脉宽、谱宽等，并从理论上进行了一些分析。
MDI's WF series waveguide Bandpass and Harmonic Filters excel in applications where high frequency, narrow bandwidth and high 'Q' are essential.
MDIWF系列波导通频和谐波滤波器，擅长应用与高频，窄带宽和高Q频率。
The common expression for bandwidth in terms of 1/Q is neither logical nor helpful in clear exposition.
因此天线的带宽和Q 综值之间的关系在当时的确是个没有搞清楚的问题。
