The factors affecting the superprism effect have been analyzed . this greatly helps the design . the researches for superprism property in one - dimensional photonic crystals indicates that it is very difficult t
为了克服这个困难，根据空间位移与时间延迟的关系，本文对非周期的一维结构进行了深入的分析。
Because the feature size of subwavelength diffractive microlens is smaller than the incident wavelength , scalar diffractive theory cannot be used to the analysis . it also precludes rigorous vector coupled - wave theory for its finite and aperiod structure
由于亚波长衍射微透镜的特征尺寸小于入射波长，因此不能采用标量衍射理论来分析，又由于它是有限非周期的结构，严格的耦合波方法对它也不适用。
For a plc network , the length of the mac layer frame is associated not only with the method used in media access control but also with the nature of the interferences , since it suffers from a variety of interferences which are non - periodic and asynchronous
对于plc网络，由于信道存在严重的非周期的异步脉冲干扰，其mac层的帧长度不仅与采用的介质访问控制方式有关，而且与电力线上的脉冲干扰有关。
