The rainstorm process is a complex and stochastic multi-dimensional process.A correlation exists between the maximal annual period-storm and the rainfall duration,with overlooking many factors,the parameterwill not be a constant.Since 1980s,heavy rain and flood of small basins can be calculated by auto-recording rainfall observation system,and 20-year's self-recording rainfall data can improve the calculation accuraey.

暴雨过程是一个复杂的多维随机过程，年最大时段暴雨xt，p与暴雨历时t的暴雨公式属于经验相关关系，忽略了不少影响因素，因此，公式中参数n值不会是稳定不变的。20世纪80年代以后，随着自记雨量观测应用，到目前已经有20多年的资料系列，小流域暴雨设计的计算就可以直接利用时段实测降水资料系列进行计算，设计洪水时，可根据实测雨量时段资料，计算该设计流域的n值，可提高计算精度。

In the study of the stochastic chaos in simple pendulum, the random Melnikov process is derived and the mean-square criterion is used to determine the threshold amplitude of the bounded noise excitation for the onset of the chaos or random chaos in the system. For the coupled simple pendulum and harmonic oscillator, the Melnikov function is used to determine the condition for the onset of chaos in the case of Hamiltonian perturbations. In the case of non-Hamiltonian perturbation, the generalized random Melnikov process and mean-square criterion are used to determine the threshold amplitude of the bounded noise for the onset of random chaos.
