非线性振动
说明: 非线性振动.pdf 刘延柱编写
恢复力与位移不成正比或阻尼力不与速度一次方成正比的系统的振动。尽管线性振动理论早已相当完善,在工程上也已取得广泛和卓有成效的应用,但在实际问题中,总有一些用线性理论无法解释的现象。一般说,线性模型只适用于小运动范围,起出这一范围,按线性问题处理就不仅在量上会引起较大误差,而且有时还会出现质上的差异,这就促使人们研究非线性振动。(Nonlinear Vibration. Compilation of PDF Liu Yanzhu)

说明: 常用于分析降水、径流、气温等要素时间序列的趋势变化,其优点在于样本不需要遵循某一特定的分布,而且很少受到异常值的的干扰,计算简便。(It is often used to analyze the trend change of time series of factors such as precipitation, runoff and air temperature. Its advantage is that the sample does not need to follow a specific distribution, and is rarely disturbed by outliers, so it is easy to calculate.)
