The frequency range and distortion model affected by Faraday rotation were analyzed. A kind of calibration algorithm was introduced, in which trihedral corner reflectors were used to calibrate POLSAR image subject to channel imbalance, Faraday rotation and RCS distortion. [2]Three kinds of target decomposition theorems used to extract polarimetric features of SAR image were studied in detail. A kind of POLSAR MLC image data decomposition method based on classical coherent decomposition theorem of POLSAR SLC image was introduced, which was used to extract polarimetric features of POLSAR MLC image.

Engineers can compare calculation results with the tunnel design curve in order to obtain deviation values of horizontal position, vertical position and angles of the shield machine, and can adopt these results to control tunneling operations of the shield machine.

隧道设计曲线是在城市三维坐标系中设计的，要得到盾构机掘进过程中的误差，就必须通过测量计算得到盾构机在绝对坐标系中的坐标位置和方位角。

Results The Mapcheck offers the dosimetric characteristics required for performing both relative and absolute dose measurements.

结果：Mapcheck在高能光子照射下剂量重复性和线性均满足临床要求，而Mapcheck所测的绝对剂量和相对剂量分布，与计划剂量分布的比较显示，也在可接受的误差范围内。

In order to calibrate the model, data of six typhoons such as the flood peak and the peak time are collected to compare with the result of the simulations. The result shows that the difference of the inflow hydrograph between them is very close. The average error of the flood peak is 5.21%. Furthermore, the error of the peak time is less than one hour but Wenny Typhoon is an exception by more than two hours. Therefore, the model could be applied to simulate the rainfall event at Shih-men watershed.

为验设模式模拟精确性，本研究以具代表性之六场台风降雨模拟，针对石门水库入流历线之观测流量与模拟值比较，结果显示模拟之水库入流历线与观测值差异不大，其尖峰流量误差绝对个平均为5.21%；另在预测洪峰到达时间方面，除温妮台风迟迟2小时外，其余均在1小时内，显示本分析模式可应用於石门水库上游集水区暴雨事件模拟。
