因此，针对声源方向感受此一课题，以两反射音之模拟声场进行实验探讨，研究方法不仅以数理解析，并针对人们实验的心理感受进行调查分析，心理实验时采用配对比较法及恒常性图解法统计分析，试图藉由若干变因的控制进行量化，实验结果发现声源方向感度的变化，主要受制於双耳互函数级数及全反射音振幅的大小，双耳听觉互函数主要与反射到达测听者的方向和反射的幅度有关，证实声源方向感度与双耳互函数级数为正比之关系存在。

In this dissertation, many works have been done on the basis of the summarization of the merits of all kinds of meshless methods after a large number of relevant references are read and studied. The basic ideas, principles of meshless methods and their development in the recent years are introduced synoptically. Applications of Element-free Galerkin method in elastic foundation plate are studied deeply and some useful conclusions are obtained as follows:(1) Comparisons between numerical solutions and analytical solutions for several different styles of weight functions, including Gaussian weight function, spline weight function and singular weight function etc, are performed. The results show that Gaussian weight function is the best one.(2) Ranges of relevant parameters for Gaussian weight function are given.(3) Influences of nodal distribution schemes and the number of Gaussian integrated dots on computational results are discussed.

For the first patern, elastic dynamics is adopted to study the steady state rolling contact, elastic dynamics incorporating with rigid dynamics is adopted to study the non-steady state. For the steady state, the analytical solution is obtained, and for the non-steady state, the variational formulation to solve the problem numerically is derived For the later patern, the function type friction coefficient is introduced.
