圆边

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。

A new method relying on the Stroh formulism and the theory of the surface impedance tensor was developed to investigate the dynamic instability of interfacial slip waves.The concept of the surface impedance tensor was extended to the case where the wave speed is of a complex value,and the boundary conditions at the frictionally contacting interface were expressed by the surface impedance tensor.Then the boundary value problem was transformed to searching for zeroes of a complex polynomial in the unit circle...

On the first day, when, getting up early in the morning, he came out of the shed into the dawn, and saw the cupolas and the crosses of the New Monastery of the Virgin, all still in darkness, saw the hoar frost on the long grass, saw the slopes of the Sparrow Hills and the wood-clad banks of the encircling river vanishing into the purple distance, when he felt the contact of the fresh air and heard the sounds of the rooks crying out of Moscow across the fields, and when flashes of light suddenly gleamed out of the east and the sun's rim floated triumphantly up from behind a cloud, and cupolas and crosses and hoar frost and the horizon and the river were all sparkling in the glad light, Pierre felt a new feeling of joy and vigour in life such as he had never experienced before.

第一天，他一大早就起了床，走出棚子，头一眼就看见新圣母修道院开始还发暗的圆屋顶和十字架，看见覆盖着尘土的草上的寒露，看见麻雀山的丘陵，看见隐没在淡紫色远方的，长满了树木的，蜿蜒着的河岸，他觉得空气清新，沁人肺腑，可以听到从莫斯科飞越田野的乌鸦的啼叫声，一会儿，在东方天际边，突然喷射出万道霞光，一轮红日从云层里渐渐显露出来。于是，圆屋顶，十字架、露水、远方和那条小河——所有这一切都在阳光下闪烁，这时，皮埃尔感觉到一种从来都没有经历过的，全新的，生活的喜悦和力量。
