说明：  comsol仿真的学习教程，有助于初学者深度掌握comsol的 基本使用(Comsol simulation course is helpful for beginners to master the basic usage of COMSOL)

该程序实现的功能是给定两个整数n和m，0<n< m< 200，你的程序要计算第n个素数到第m个素数之间所有的素数的和，包括第n个素数和第m个素数。(The function of the program implementation is given two integers n and m, 0 < n < m < 200, your program to calculate the NTH prime number between the first m prime and all the prime Numbers, including the NTH prime number and the first m a prime.)

这是用于求解精确求解zoeppritz方程的程序，可用于AVO反演，合成地震记录等(This function computes the particle displacement reflection and transmission coefficients (the relative displacement amplitudes) for a solid-solid interface, a liquid-solid interface, a solid-liquid interface, and a liquid-liquid interface. The medium on each side of a given interface is perfectly elastic. The output is the value of the reflection or transmission coefficient, specified by the user at the incidence angle anginc (see input parameters). )
