Within this context, four specific areas are addressed:(1) By means of finite integration technique, a new kind of the first order partial difference equation is derived from the original disperse transmission line equation of the uniform waveguide's. As it is the kind of one dimension Dirichlet's boundary problem, it is convenient for us to solve this equation from the leapfrog scheme. Because computation is carried out in one dimension, both high calculation efficiency and precision have been obtained in this method. Meanwhile, this method provide us a different selection to simulate the transient response of waveguide with non-simplical, for examples cylinder and elliptic waveguide, and avoid solving the second order equation, or using finite difference time domain to simulate a three dimension problem, sometimes the latter precision is not satisfied with the need, or low efficiency.

在这一研究内容下，主要研究四个方面的问题：(1)在完成金属波导传输线方程时域形式的基础之上，应用有限积分技术，把波导特征模式的色散传输线方程，化简为一组新的一阶偏微分方程组，该边值问题属一维Dirichlet边值问题，从而便于用蛙跳格式求解，由于是在一维中计算，该方法具有很高计算效率和精度，从而避免了以往为得到金属波导中特征模的时域响应特性，须要求解二阶方程，或用时域有限差分方法求解三维问题的方法，对于后者来说，计算有时是不准确的，或是很耗时的例如计算诸如圆波导、椭圆波导等其它复杂形状的波导。

First of all, ink is the packaging business card printing and membership card to make the most basic requirements, the balance as a result of offset printing and ink-and-ink, therefore emulsibility ink consistent offsctdruckereien became a universal problem, and that is the strength of the Conference and, secondly, packaging design has a color swatch, icons, offsctdruckereien in addition to the Phantom of the Opera problem, the deposit in the event also had extensive 专色色 you have to print twice or even three times, and the printing business card printing and membership card deposit made it much more than offset printing.

首先，墨色一致是包装物制卡和会员卡制作的最基本要求，而胶印由于有水墨平衡和油墨乳化的问题，因此墨色一致便成了胶印的大难题，而这正是柔印的长处；其次，包装设计有着大量的色块、图标，胶印除了有鬼影的问题外，墨层也不够厚实，遇到大面积的专色色则不得不印两遍甚至三遍，而柔版制卡和会员卡制作的墨层厚度却远远超出胶印。
