运动学模型中把悬架简化成杆系结构，而各个杆件看成是绝对刚性的，铰点处也认为是只有纯转动而无任何橡胶件的变形，这样所得的结果就有一定的误差。

Based on teaching function for generation of workpeice process program, this paper suggests an interpolation algorithm of space line and arc and the transformation of space absolute coordinates to machine motion coordinates.

摘要在示教生成零件加工程序的基础上，讨论了空间直线和圆弧的插补算法以及空间绝对坐标到机床运动坐标的变换，并对插补算法的误差进行了分析。

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.

当工作频率小于1GHz时，法拉第旋转是影响低频星载极化SAR图像定标的一个重要因素，论文分析了受法拉第旋转影响的波段范围和误差模型，提出了一种校正通道不平衡度、法拉第旋转和绝对幅度增益的极化定标算法，仅使用一种点目标——三角反射器作为定标体，应用于受法拉第旋转影响的极化SAR图像定标； [2]深入研究了三类用于SAR图像极化特征提取的目标分解理论。

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。
