计算了高斯型脉冲宽度在色散缓变光纤中的传播特性和初始啁啾对脉宽演变的影响。
The propagation characteristics and the influence of initial chirp on Gaussian pulse width were discussed.
结果表明 ，激光脉宽是影响焊接接头性能的主要工艺参数 ，通过控制激光脉冲宽度可以获得高质量的镁合金焊接接头。
The results showed that the pulse width was the main parameter affecting properties on the joint and the high quality joint can be obtained by controlling the pulse width.
在相同的平均功率、峰值功率和脉宽比下，脉冲宽度是影响切缝宽度主要参数。
In the same of average power, peak power and duty cycle constant, pulse width is the primary parameter which affects the kerf width.
但作用距离的分辨率却与发射脉宽成反比，脉冲宽度越窄，则频谱越宽，测距越精确。
But the resolving power of radar is in inverse proportion to the pulse-width. The pulse is the narrower in width , then the wider frequency spectrum is, it is the more accurate to find range.
