非线性振动
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)

上三角或下三角矩阵也有大部份的元素不储存值(为0),我们可以将它们使用一维阵列来储存以节省储存空间,而对称矩阵因为对称于对角线,所以可以视为上三角或下三角矩阵来储存。(Upper or lower triangular matrix or a large majority of elements are not stored value (0), we can use them to store a one-dimensional array in order to save storage space, and because the symmetrical diagonal symmetric matrix, it can be regarded as the or lower triangular matrix storage.)
