Second, proceeding with the fact thatthe constructing vector wave functions of conventional circular cylindrical and sphericalvector wave functions are linear independent solutions to the electromagnetic field waveequations in biisotropic medium,spectral impedance boundary conditions are proposed forinfinitely long perfectly conducting circular cylinder and sphere coated with biisotropic media,respectively,which generalize the applicable range of planar structures and are suitable toanalyze the electromagnetic problems involving their counterpart structures.

所用的方法是在Fourier变换谱域中的一阶线性微分方程组理论和矩阵技术，提出了适用于Chiral媒质半空间辐射问题的耦合镜像原理(即镜像电流的振幅和相位是由Chiral媒质中的本征左、右旋圆极化波相互耦合来确定的)和适用于研究平面分层Chiral媒质电磁问题的一般性更高的分析方法。

Should adopt the left decubitus, such supine increased uterus dextral correct, can reduce the uterus to the abdominal aorta and iliac artery of oppression, to improve blood circulation, increase blood volume for the fetus and is conducive to growth and development of the fetus .

宜采取左侧卧位，此种卧位可纠正增大子宫的右旋，能减轻子宫对腹主动脉和髂动脉的压迫，改善血液循环，增加对胎儿的供血量，有利于胎儿的生长发育。

The collisional absorption of the right circularly polarized wave and the left circularly polarized wave propagating parallel to the magnetic field by inhomogeneous magnetized plasmas is discussed, and the attenuations are calculated under different conditions.

讨论了不均匀磁化等离子体片对平行于磁场方向传播的左、右旋圆极化电磁波的碰撞吸收，计算了不同条件下衰减率。计算表明，当电磁波的频率接近电子碰撞频率时，磁等离子体对电磁波的吸收达到最大值。

It was like rushing down an endless, slimy, dark hole. He could see more pipes branching off in all directions, but none as large as theirs, which twisted and turned, sloping steeply downward, andhe kne wthat he was falling deeper below the school thatn even the dungeons...and then...the pipe leveled out, and he shot out of the end with a wet thud, landing on the damp floor of a dark stone tunnel large enough to stand in.

那好像沿着一条又黑又黏，没有尽头的地洞，他可以看到四面八方都有管道伸展开去，但是都没有像他们所在的这个大，而这条管道左转又旋，陡然直落，他知道他们现在已经落到学校下面，比地下室还深的地带……然后……下水道忽然平了，他从管道尽头&砰&地一声滑了出来，掉在潮湿的地板上，这是一间足够高得能站人的漆黑石道。

In this literature, expert interviews is based on observation,experiment and mathematical statistics to the point of view of new innovative moves to martial arts foot Tornado Mabuchi 900 ° access to the analysis,The so-called new perspective is that in this paper has opted for the left and right hip three-dimensional coordinates and speed of analysis, a more intuitive grasp of a more accurate body rotation and the rotation axis and the location of the changes in the body's adjustment to posture .

本文采用文献资料法、专家访谈法、观察法、实验法、数理统计法以全新的角度对武术创新动作旋风脚900°接马步进行了分析，所谓全新的角度是指，在本文中选择了对左、右髋三维坐标和速度进行了分析，能更直观更精确的掌握身体的转动情况和旋转轴的位置变化情况及身体姿态的调整情况。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
