| 摘 要： | 波与粒子的环形漂移共振作用导致一些与等离子体色散函数有关的高阶共振积分。通过适当的复变换可以将它们化成有限区间中的正常积分,它特别适合于复参数虚部很小时的积分值的计算。

| Abstract: | The resonance interaction of plasma waves with the toroidal drifts of particles leads to the occurence of a class of high order resonance integrals, which are related closed with the plasma dispersion function. Ordinary integral forms of them in finite region have been obtained by suitable complex transformation, that is very useful for their numerical calculation in case of the imaginary part of the complex parameter being small. |
