偏角

The physical model of polarizing beam coupling and splitting system using altazimuth coude telescope is built up based on Mueller matrix and Stokes vector. The phenomena of the decreasing of the receiving efficiency are successfully explained by this model. Three dynamic phase compensation solutions are proposed: 1 Two quarter-wave plates are rotated to compensate the phase of the laser.

In the third part, the theory of thrust angle and unbalanced forces is studied andapplied to Xiluodu arch dam. some conclusions are obtained :(1) The thrust angle issmaller by elaso-plastic computation than elastic computation. For the non-linearcomputation, the thrust angles at different elevations all increase during overloading,which reveals the internal mechanism of good performance of arch dam in conditionof overloading;(2) The elaso-plastic theory always minimizes the actual unbalancedforces in the sense of a condition number in the norm ofcomplementary energy.

第三部分，通过对溪洛渡拱坝拱端推力角及不平衡力的研究，得出如下结论：(1)非线性计算较弹性计算的推力角大；对于非线性计算而言，拱坝超载过程中各高程段的推力角均有所增加，这反映了拱坝具有较高超载能力的内在机制；(2)在总余能范数的意义上，按弹塑性本构关系确定的不平衡力或加固力是最小的，弹塑性计算确定的加固力和真解相比偏于安全。

Because of the dependence of rotating dipole PA curve on layer of field lines, it avoids the degeneracy problem of conventional rotating vector model that all layers of field lines have the same PA curve with fixed inclination and impact angles, therefore it provides a useful way to identify the emission from different layers and constrain the location of emission regions in pulsar magnetosphere by fitting the observed pulsar radio PA data with rotating dipole PA curve.

其与磁力线层等参数的依赖关系避免了传统旋转矢量模型的简并问题－在给定磁倾角和碰撞角情况下所有层磁力线的偏振位置角曲线都一样，这为通过拟合射电偏振观测数据来分辨不同层的辐射，从而限定脉冲星辐射区部位提供了一条有用的途径。

By contrast with the spectral obtained under different incident geometry and polarized conditions, the experimental results show that the reflected light can be corrected completely with an incident zenith angle of 53 degree (Brewster's angle) and zero polarized angle.

结果表明，当探测角不满足布儒斯特角时，在偏振片的主消光方向能剥离绝大部分的水面反射光；当入射角越接近布儒斯特角，其剥离效果越佳；以布儒斯特角观测时，可以达到完全剥离的效果。

The many hybrid wheat combinations were bred by 4 male sterile types of alloplasmic wheat with Ae.kotschyi,Ae.variabilis,Ae.ventricosa and Ae.bicornis cytoplasms and some restoring lines,and their seed qualities were analysed.

At present, the location of the anti-lopsided wear centralizer used in fields is mainly based on the deviation angle. In fact, lopsided wear may be caused by the change of azimuth angle or by the vertical well section and hold angle section during the working of the bucket rod.

目前油田矿场主要根据井斜角来确定防偏磨扶正器下入位置，实际上方位角变化也能导致偏磨，抽油杆杆柱在运动过程中直井段和稳斜段也会产生偏磨。
