摘　　要：（１）首次系统地和明显地给出了ＧＭＥ和ＣＴＲＷ在Ｌａｐｌａｃｅ－Ｆｏｕｒｉｅｒ表象的严格解以及时间－动量的一般解和渐近解；（２）讨论了上述各种形式的解的应用并给出了平均平方位移的各种表达形式．In this paper (1)exact solutions of Laplace-Fourier representation of generalized master equation (GME) and continuous time random walk (CTRW) and general solutions and asymptotic solution of time-wave-vector dependence of them are systematically presented explicitly for the first time. (2) Some application of the solution as mentioned above are discussed and certain forms of expressions for the mean-displacement and the mean-squared displacement are given.
