1.
Based on the approximate descriptions between the frequency-width Δν and coherent τc time about light source time-coherence by using Newton iterative method, the more precise relations is derived between them.
针对光源时间相干性中频谱线宽Δν与相干时间τc的关系(Δν≈τc)的粗略表达,运用牛顿迭代法对两者的关系进行了较精确的推导,并对其误差及范围进行了讨论。
2) Spectral bandwidth
频谱宽度
1.

频谱宽度
1.
Influence of the spectrum width on the ultrashort pulsed beams;
频谱宽度对超短脉冲光束的影响
2.
The spectrums of the ultrashort pulsed unchirped and chirped cosine-Gaussian beams are given,which draws a conclusion that the broad spectrum width is the original reason for the spatial singularity.
结果表明不同脉冲宽度的无啁啾余弦高斯脉冲光束的频谱以及相同脉冲宽度下啁啾余弦高斯脉冲光束的频谱有着很大不同,直观地看出了脉冲宽度和啁啾对超短余弦高斯脉冲光束频谱宽度的影响,说明了频谱宽度对超短余弦高斯脉冲光束空间奇异性有很大的影响。
4) wide frequency range
宽频谱
1.
To make the evaluation easy to perform in wide frequency range, th.
在此基础之上,引入耦合长度随来波方向的分布概率,进而提出了超过一定概率的耦合长度Lth来评估微带天线在宽频谱内的受扰特性。
补充资料：IC工艺线宽
线宽:4微米/1微米/0.6微未/0.35微米/035微米等,是指IC生产工艺可达到的最小导线宽度,是IC工艺先进水平的主要指标.线宽越小,集成度就高,在同一面积上就集成更多电路单元.
