摘要
用解析和数值方法研究了薄随机泵层的阿诺扩散系数,与厚随机泵层类似,当各种参数较小时,解析和数值计算两种方法结果相符合,而参数较大时出现了差异,同时分析了解析理论不适用的原因。
The Arnold diffusion of thin stochestic layer is investigated by the analytical and numerical method. The result of which is the same as it is investigated on thick stochastic layer. For the small paramerter, the theoretical predication agrees well with the numerical findings. For the large parameter, however, deviation emerges and the reasons for it are given.
