The lowest loss mode fields and the far field divergency angles of output beams of the UPCUR are calculated by use of Prony method. The relations between the mode discriminability, far field divergency angles and the parameters of the resonator are analyzed. And the theoretical results show that the output beams with diffraction limit quality can be obtained by using the UPUR with small magnification (M=1. 3), which is much better than the traditional unstable resonator under the same conditions.

采用Prony方法计算均匀相位输出耦合镜非稳腔的输出模场分布及远场方向性，分析了模式分辨率和光束远场发散角与系统各参数之间的关系，理论计算得到的结果表明，采用均匀相位输出耦合镜非稳腔，可以在小放大倍率(M=1.3)情况下得到质量达到衍射极限的输出光束，远远好于同等条件下的常规非稳腔，因此这种新型的谐振腔适用于在工业用千瓦级氧碘化学激光器。

The degree of twist distortion increases with pretilt angle.

同一种液晶分子在取向层的预倾角不同，在力场作用下扭曲变形的程度亦不同，预倾角较大可获得较大的扭曲角；对于不同的向列液晶，弹性常数较小的液晶可在较短的时间产生较大的扭曲变形

The results show that the fine-grained hypidiomorphic pyrite, with a crystal form of pentagonal dodecahedron, contains more Au than others. Since the areas yield pyrite with relatively lower contents of main components S and Fe, while a greater gross content of trace elements, such as Cu, Pb, Zn, Au, Ag, are closely associated with gold deposits, the authors propose that a middle-scale gold deposit might be found in Zhaojiapuzi area; and there is a remote possibility to find a large gold deposit in Shengjingao area, wih a prospect of finding a concomitant gold deposit.gold deposits;mineralogical.
