Because of the mid course correction of one arbitrary constant in each step, the accuracies of the formulas are maintained at around 2%. 由于在每一步都有一个任意常数进行中段校准,所以所有这些公式的精度可以保持在2%左右。
By obeying the smallest side-to-side distance routing rule and keeping the center-to-center distances between arbitrary two of three lines ( microstrips and the guard trace) constant, the guard trace inserted should be as wide as possible. 在满足线间距布线规则的前提下,将防护线适当加宽而又维持三条线(防护线和两条微带线)中两两之间的中心距不变,就能够有效减小线间的远端和近端串扰。
Dynamic Behavior of Soliton in Optical Fibre with Arbitrary Perturbation of the Dielectric Constant 在介电常数正弦扰动的光纤中的孤子动力学行为
A method to calculate the propagation parameters of optical fibers with arbitrary index profile is introduced. The propagation parameters of three different optical fibers, for example the normalized propagation constant, the chromatic dispersion and the mode field diameter, is calculated and analyzed. 介绍了具有任意折射率分布的光纤传输特性参量的计算方法,利用这种方法计算并分析了三种不同折射率分布的光纤的归一化传播常量、色散和模场直径等传输特性参量。
