First of all,we have given some of the basic concepts of differential equations, described the constant coefficient linear ordinary differential equation solution, for a class of second-order variable coefficient linear ordinary differential equation initial value problem, an approximate solution, the method is first unknown function of a definition for N sub-interval, and then in between each district within a constant coefficient ordinary differential equations similar to the replacement, the solution has been the problem as similar to the original analytical solution, and then gives a detailed second-order change order coefficient of linear homogeneous ordinary differential equation solution examples, the examples of the approximate method proposed in this paper is valid.
首先给出了微分方程的一些基本概念,讲述了常系数线性常微分方程的解法,针对一类二阶变系数线性常微分方程初值问题,提出了一个近似解法,本方法是先对未知函数的一个定义区间作N等分,然后在每一个小区间内用一个常系数常微分方程近似替换,所得到的解作为原问题的近似解析解,随后详细给出了一个求二阶变系数齐次线性常微分方程的解的实例,该实例说明本文提出的近似方法是有效的。

Rather let it be named from the fishes that swim in it, the wild fowl or quadrupeds which frequent it, the wild flowers which grow by its shores, or some wild man or child the thread of whose history is interwoven with its own; not from him who could show no title to it but the deed which a like-minded neighbor or legislature gave him ——him who thought only of its money value; whose presence perchance cursed all the shores; who exhausted the land around it, and would fain have exhausted the waters within it; who regretted only that it was not English hay or cranberry meadow —— there was nothing to redeem it, forsooth, in his eyes —— and would have drained and sold it for the mud at its bottom.
这个湖还不如用在湖里游泳的那些鱼的名字,用常到这湖上来的飞禽或走兽的名字,用生长在湖岸上的野花的名字,或者用什么野人或野孩子的名字,他们的生命曾经和这个湖交织在一起的;而不要用他的名字,除了同他志趣相投的邻人和法律给他的契据以外,他对湖没有什么所有权,——他只想到金钱的价值;他的存在就诅咒了全部的湖岸,他竭尽了湖边的土地,大约还要竭泽而渔呢;他正在抱怨的只是这里不是生长英吉利于草或蔓越橘的牧场,——在他看来,这确实是无法补偿的,——他甚至为了湖底的污泥可以卖钱,宁愿淘干湖水。
