Co - producer rick porras ' s wedding ring was the template for the one ring
剧中的至尊魔戒，是用制片人里克?波拉斯的结婚戒指作的模铸出来的。
Chapter 2 : the basics equations and the complex analytical signal theory are introduced
第二章：首先介绍了porras提出的超短脉冲光束表达式和复解析信号理论。
If assuming the chirped parameter is equal to zero , our results deduce to that of porras
令啁啾系数为零，则我们的结果可以演化为porras等人关于无啁啾脉冲光束的结果。
Porras and fu et al proposed that slowly varying envelope approximation and the complex amplitude envelope do n ' t fit anymore for the ultrashort pulsed beam shorter than or even near to one oscillation optical period , because they lead to a spatial singularity
结果表明，对于脉冲宽度较长(相对于一个光学周期)的超短无啁啾脉冲光束可以使用缓变包络近似和复振幅包络表达式。
