Furthermore, it has electrical light effect, magnetooptical effect or thermal light effect in outside field.

如果入射光是沿螺旋轴方向，那么布喇格反射是圆偏振的；在斜入射的条件下，反射光将是椭圆偏振光。

From Maxwell's equations, with material constitutive relation of optically active crystal and boundary conditions of electric field on the boundary between isotropic media and crystal, through coordinate transformation, the formula of the direction of refracted wave for arbitrary direction incident monochromic plane wave was derived. Furthermore, based on the unit vector of direction of refracted wave, eigen waves of electric field, electric displacement vectors and direction of energy flow can be easily obtained.

从麦克斯韦方程组出发，结合旋光晶体的物质方程以及单色平面波从各向同性介质入射到晶体界面时电场的连续性边界条件，通过晶体主轴坐标系和界面坐标系的坐标变换，推导了任意入射方向的单色平面波在晶体界面上的折射方向的求解公式，进而利用所得的折射方向求解晶体中折射波的电场本征模、电位移矢量本征模和光线方向。

The shortcoming of ordinary multimode Y branch optical power splitter is that the branch characteristic strongly depends on the excited modal distribution. Different input conditions including different input modes and different input positions will excite different modes and different intensity distribution of these modes in highly multimode waveguides. The interference of these modes will contribute to distribute unstably, i.e.

多模Y分支器件的设计中存在一个共同的问题，即随着光入射条件的不同(包括入射光的模式不同和输入进波导端面位置不同等)，多模波导中所激励起的模的数目以及各个模之间的功率分配也各不相同，激励起的多个模式之间总是存在着不同程度上的相互干涉影响，从而最终影响功分器的分束均匀性。

It can be concluded that, when the jet is injected at positive angles, the initial section of the jet increases and the region affected by the jet decreases in the vertical direction; moreover, the circumfluence toward the jet exit becomes more obvious, and the separation events in the lee of the jet weaken. When the jet is injected at negative injection angles, it disarranges the flow upstream and the curvature of jet trajectories varies smartly along the flow direction.

结果表明：射流正向倾斜入射时，射流起始段增加，在垂直方向对主流场的影响区域减小，射流喷口上游位置处的&孔吸流动&更为明显，射流出口下游背风侧的分离现象逐渐减弱；射流反向倾斜入射，对上游流场的扰动增加，射流在弯曲段内曲率变化大。

The results show that the noise of original image is effectively suppressed and ridded after the preprocessing treatment,and the intensity distribution is comparatively smooth.

在入射光束为基模高斯光束的条件下，随着入射光能量增大，受激布里渊散射光斑的空间光强分布由近高斯型转变为高斯型。

First, the background spectrum is subtracted from experimental one; Second, by the spectrum stripping, the counts came from partial energy deposition of incidence photon in HPGe crystal, such as Compton scatting or pair production; the next, transform the experimental spectrum to the incidence photon flux spectrum.

实验数据的处理过程有三步：1 从实验谱中减掉本底谱；2 实验谱中分离掉各种能量的入射光子在晶体中的部分能量沉积(康普顿散射、电子对效应)：3 处理过的实验谱转成入射光子通量谱。比较结果显示，在本实验中，模拟谱对实验谱的总计数相对偏差不大于20%，两者基本符合。

Ultraviolet light is made to projected successively to sample template, phase template and fiber or successively to diaphragm, shutter, phase template and fiber.

它是使紫外光依次入射到取样模板、相位模板和光纤上，或依次入射到光阑、快门、相位模板和光纤上。

G. it is up to 80 eV when the cluster plane is parallel to the surface. In addition, the impact induced adsorption of C〓 cages was studied in detail. After impacting, the normal incident C〓 was found to move laterally on the surface due to the anisotropic interaction between the dimerized surface and the cage. Finally, it resided on the top of a dimmer or in the trough, which are the energy favored adsorption sites.

在能量为10-20eV的C〓富勒烯表面吸附动力学过程的研究中，我们还发现表面结构的不对称性会引起团簇-表面相互作用的各向异性，从而导致入射团簇在表面上有与入射方向垂直的的横向运动，最后吸附在两个二聚体的中心点和谷点，这两个位置是能量最低的的吸附组态。

After eliminating the isotopic backgrounds using the AMS technique, the isobars can be distinguished with their emitted characteristic X-rays when the projectile ions collide with target.

Simulation results show that both the longitudinal and transverse wave are included in the reflected waves,the reflection coefficient of longitudinal wave augments with the increase of the incident angle,and the reflection coefficient of transverse wave augments first and then minishes,the transverse wave disappears when the incident angl.

主要研究了声波从粘弹性介质向流体介质斜入射情况下的声反射特性，分析表明：反射声波中有横波和纵波同时存在，纵波声压反射系数随入射角度的增大逐渐增大，横波的声压反射系数随入射角度的增加先增大后减小，在垂直入射时只有纵波，而没有横波存在。
