查询词典 system function

Since the multiple scattering should be considered, the scattering problem of many-cylinders is more complicated than single cylinder. By using scattering matrix method to solve the scattering problem of many-cylinders, first we have to express the incident fieldand scattered field by special function（for example, Bessel function and Hankel function）under cylindrical coordinate, then use the addition theorem of special function to get a linear system of equations to relate the incident field coefficients and scattered field coefficients. The incident and scattered field coefficients for every cylinder can be solved from the linear equations by matching electromagnetic boundary condition pointwisely.

单颗圆柱散射体的散射场解析解很早就被解出，而多个圆柱阵列的散射场问题因为涉及到入射光在圆柱与圆柱间的多重散射，故散射行为较单颗圆柱的散射复杂，因此圆柱阵列的多重散射问题需要利用加法定理来处理；散射矩阵法的主要精神即是先用圆柱座标下的特殊函数对平面波和圆柱散射体的内外域电磁场做无穷级数展开，再藉由特殊函数的加法定理将所有圆柱散射体的展开中心移到同一个展开中心，最后可以得到一组连结整个散射系统的入射电磁场系数及散射电磁场系数的线性方程组，将该组线性方程配合电磁场在散射体边界的连续条件，便可分别求出圆柱阵列中各个圆柱体的内部电磁场与外部散射场，再利用线性叠加原理即可求得整个圆柱系统的全域电磁场分布。

As a result of conservative perturbations, the first order Melnikov function for a perturbed system is identically equal to zero, so the second order Melnikov function has to be considered. The perturbation parameters which make no use in the first order Melnikov function may be important in the second order Melnikov function.

此时一阶Melnikov函数恒等于零，必须考虑二阶Melnikov函数，而在一阶Melnikov函数中不起作用的扰动参数在二阶Melnikov函数中却起着非常重要的作用，因此扰动部分极为复杂。

From the narrow point of view, prenatal education mainly refers to the basis of fetal growth and development of the sensory organ the actual situation in a targeted manner, and actively take the initiative to give reasonable information to stimulate appropriate to establish a conditioned reflex the fetus, thereby promoting their brain function, somatic motor function, sensory function and sophisticated function of the nervous system.

从狭义上来说，胎教主要是指根据胎儿各感觉器官发育成长的实际情况，有针对性地，积极主动地给予适当合理的信息刺激，使胎儿建立起条件反射，进而促进其大脑机能、躯体运动机能、感觉机能及神经系统机能的成熟。

A better understanding of the function of spleen has been gained recently, owing to the in-depth studies on the structure, cellular function, secretion and innervation of spleen. It is generally accepted that the spleen is the important part of the regulation network between immune, nerve and endocrine system. The spleen has much more function besides blood filtering and storage, haematogenesis, and immunization, and its immune function has characteristics of \\\\\\\"two-way\\\\\\\" and \\\\\\\"phase\\\\\\\".

近年来，随着对脾脏组织结构、细胞功能、分泌功能和神经支配的深入研究，对于脾脏的功能有了更加深入的认识：脾脏是机体免疫-神经-内分泌网络调节中心的一个重要组成部分，其功能并不仅仅局限于滤血、免疫、造血和储血等，而且脾脏的免疫功能具有&双向性&和&时相性&的特点。
