摘要
基于力网系综理论,给出了两种不同的力空间中分布函数的一般形式,并且分别采用直接积分法和付立叶变换法计算分布函数的积分。通过对比发现直接积分法在K值比较小时有优势,而付立叶变换法在N值较小时有优势,两种方法都能解决一般性的积分问题。
Based on the force network ensemble theory, a general form of probability density function for force network ensemble is formulated in two different kinds of force phase space. The direct integration method and Fourier transform method are proposed to solve the integral problem of the probability density function. By comparing these two methods, it is indicated that they all can effectively solve this problem, and the direct integration method is more convenience when K is small, while the Fourier transform method has an advantage when N is small.
