Description: 小明是个小学五年级的学生，为了早点去看自己爱看的卡通，他想快点把作业做完。可是可恶的数学老师今天却布置了一道难题，小明想了很久也不知道该怎么做。你的任务就是帮小明解决掉这道数学题。
题目是这样子的，有一个整数a（-2^31<= a < 2^31-1），计算它的整数幂a^n，其中1<=n<=99。-Xiao Ming is a fifth-grade students, in order to see his early love to watch cartoons, he wanted the job done quickly. But the nasty math teacher has arranged a problem today, Xiao Ming like a long time do not know how to do. Your task is to help Xiao Ming out this math problem solving.
Topic is like this, there is an integer a (-2 ^ 31 <= a <2 ^ 31-1), calculate its integral power a ^ n, where 1 <= n <= 99.

Description: Ext rapolation operator of one2way wave field has great application in seismic migration imaging. According
to their implement , these operators can be classified into three kinds : Kirchhoff integral method , implicit definite
difference in space domain and Fourier t ransform method. They represent different operator expression methods. Dif2
ferent precisions will be got while using the operators in these methods in different t runcate order. Represent in sym2
bol in the method of derivation and accuracy analysis. Symbol of operator is the function of operator acting on sine
function. Symbol of operator is the extension of convolution operator’s Fourier t ransform. Fourier t ransform method
can be directly derived f rom symbol function’s separable approximation.

Description: 最近多种多样的电磁散射问题的研究集中在近似（数值）的解决方案。这些研究的出发点是对于电和磁域积分表示。在本文中，推导提出了一个必要的字段表示，从第一顺序麦斯威尔无追索权的二阶向量绿定理。方法
产生一个紧凑的表达式，涉及绿色的矩阵，其组件有一个简单的和直接的物理解释。制定包括科特勒线源在必要的地方没有额外的假设，并清楚地确定了不良的奇异性。-A wide vatiety of electromagnetic scattering problems have recently been studied by
rneans of approximate (numerical) solutions. The starting point for these studies is an
integral reptesentation for the electric and magnetic fields. In this paper, a derivation of
the necessary field representation is presented which proceeds the first order Maxwell
equations alone without recourse to the second order vector Green s theorem. The approach
yields a compact expression involving a Green s matrix whose components have a simple and
direct physical interpretation. The formulation includes Kottler line sources where necessary
without additional assumptions and clearly identifies the undesirable singularities.
