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。

Pararosaniline was the most accurate and sensitive method of determining SO2 residue, and it was fit for the samples of any SO2 content. Improvement pararosaniline method was only fit for the samples of high SO2 residue. Iodometry was not fit for the deep color samples and low SO2 residue samples. The fast determination method could be used the quality and semi-quantitative determination of SO2 residue in edible fungus.
