We have also presented the ω-circulant boundary condition and compared it with the helix boundary condition. Furthermore, we can also get another new boundary condition: the mixed boundary condition.

由此我们提出了ω循环型边界条件并将其与普通循环型及螺旋型边界条件作了分析和比较；进一步地，得到了一种新的边界条件：混合型边界条件。

Common Reflection Surface stack is a brand-new and special ZO imaging method, the theory of CRS stack stems from paraxial ray theory, the biggest difference between CRS stack and conventional ZO imaging method is that it consider a reflector R as a circular reflector segment Cr placed in the vinicity of reflector R, Cr can be seen as the second order approximation of the reflector. The CRS traveltime surface is the multi-coverage reflection response of the reflector mirror assigned to R.

共反射面元（CommonReflection Surface=CRS）叠加技术是一种全新的、特殊的零偏移距剖面成像方法，CRS迭加理论源于傍轴射线理论，它与普通的零偏移距剖面成像方法的最大区别是它认为地下反射层是由许多个小反射弧段互相叠合组成的，认为来自某反射点附近的一个邻域内的反射信息都可以对该反射点的成像作出贡献，因此对该反射点进行零偏移距成像时就应该聚焦更多的能量参与迭加。

The new antenna has the advantages of sim ple structure, easy feeding and a wide frequency range, and circular polarized wave. The characteristics are m uch better than a bifilarbackfire helicalantenna, a shortbackfire antenna and a backfire...

它具有结构简单、馈电方便、遮挡小、频带宽、增益高且易于产生圆极化波等优点，性能远优于带相同接地板的螺旋天线、普通短背射天线以及单线背射螺旋作馈源的短背射天线。

我的居所，比起一所大学来，不仅得宜思考，更得宜潜心阅读；虽然我置身于普通图书馆的流通范围之外，我确深受那些世界范围内流通书籍的影响，先前那些词句写在树皮上，如今只是偶尔被复制到亚麻纸上了。
