- Here are some references for nrqcd & nrqed : renormalization group scaling in nonrelativistic qcd on the multipole expansion , the qcd heavy quark potential to order v * * 2 : one loop matching conditions on matching calculations
11下面是非相对论性量子色动力学和非相对论性量子电动力学的一些参考资料：关于多极展开的非相对论性量子色动力学中的重整化群定标，关于匹配计算的v * * 2阶的量子色动力学重夸克势：单圈匹配条件。 - The major work is as follows : solution of two dimensional radiation or diffraction fluid field . this thesis extends multipole expansion method to adapt to disturbed fluid fields of 2d floating bodies with asymmetric forms , which is applied with symmetric forms originally . and given the solution of potential velocity and hydrodynamic pressure of radiation and diffraction fluid fields , which is incited by a 2d arbitrary form , actual application field of the multipole expansion method has been enlarged
关于二维扰动流场的求解：将通常仅适宜求解具有对称形状二维物体扰动流场的多极展开法(保角变换方法)扩展至非对称形状二维物体，给出了任意形状二维物体的辐射和绕射流场的速度势及水动压力的频域解，进一步扩大了多极展开法的实际应用范围。 - In this paper , the method of small parameter is used to calculate the multipolar expansion of gravitational radiation in classical situation , and the general expression on multipolar gravitational radiation is obtained . then the angle distribution characters in an arbitrary direction are given . this expansion method can avoid the higher order tensors when dealing with the gravitational radiation higher than quadrupole
本文采用小参数法作为经典引力辐射的研究方法对引力辐射作多极展开，得到各极引力辐射的一般表达式，并给出了沿任一方向引力辐射的角分布的严格证明，这种展开法在处理四极以上的高阶引力辐射时却可以不涉及更高阶的张量计算。 - Secondly , proportional arc length method is used to conformal mapping process of asymmetry sections so as to solute the 2d radiation problem with the method of multipole expansion . on the basis of above , 3d hydrodynamic coefficients are given and motions of the container ship flokstra are predicted considering the initial heel
然后，采用比例弧法对全剖面进行保角变换并在此基础上用多极展开法计算非对称剖面的辐射流场，进而采用切片理论合成全船的水动力系数并对flokstra集装箱船进行了考虑横倾影响的运动响应预报。
