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。

In the light of unbiasedness and validity of model, we identify the rigidity rotation model and rotation with strain model.

基于模型的无偏性、有效性等概念，对块体的刚性旋转运动模型、旋转应变模型进行了辨识，结果表明：同时考虑块体刚性旋转运动和应变的模型比单独考虑刚性旋转的模型更符合实际，模型的适用范围更广。

Healthy volunteers participated 6 experiments that were designed to test the sensory conflict theory of motion sickness, to observe the effect of the outside proprioceptive input on motion sickness and to make sure the influence of motion sickness susceptibility, automatic nerve activity and breed on experimental nausea and vomiting. The results were as follows: 1. Different intensity of visual and vestibular sensory conflict effected the onset of vection and rotation toleration time and the symptoms of nausea and vomiting, the more intensive of confliction, the more quickly onset of vection, the more short rotation toleration time, and the more serious symptoms of nausea and vomiting.

本研究针对上述问题设计了6个实验，以200名健康成年志愿者为被试，以转椅和转鼓作为诱发实验性晕动的装置，采用恶心评定量表、恶心问卷和晕动敏感史量表及自我运动错觉和旋转耐受时间为指标，旨在考察：（1）实验性恶心、呕吐症状的时间变化规律；（2）不同强度感觉冲突、不同体位因素对实验性恶心、呕吐的影响，验证晕动的理论假设；（3）晕动敏感史差异、人格因素、种族因素与实验性恶心、呕吐的关系。
