非互易传输线问题中的保图变换法
非互易传输线 广义Smith圆图 保图变换
2007/6/7
提出了一种全新的能够处理复杂非互易传输线（NTL）问题的保图变换方法。该方法基于一种非线性映射关系，将NTL模型的参数转化到传统互易传输线模型的参数，从而可利用标准的Smith圆图完成NTL中的设计和参数计算等问题。为了验证方法的有效性和简便性，以NTL双支节并联匹配为例，给出了完整的设计与验证过程。
旋度、散度概念精确的推广到现代物理，指出曲率张量是旋度（据引进的绝对积分），Maxwell方程是二维流的旋度、散度，宛如经典力学。

Withdrawn. The results in the paper only work for a certain subclass of Boolean functions, in which block sensitivity has properties similar to those of ordinary sensitivity. They don’t work in genera...

It is shown, that Bose-Einstein statistical distributions can occur not only in quantum system,
but in classical systems as well. The coherent dynamics of the system, or equivalently
autocatalytic d...
