上面是我们得第四问,跟第一问是很不同的....不过也有联系第三问的,评分标准我已经看过了,对了,你的QQ是多少?我们正在筹划建立学校的数学建模协会,还有建了一个网站:华南农业大学 数学建模援助交际网(有准备改名)有时间看看我们做得怎样?

<>呵呵，刚发短信给你问你QQ呢</P>
<>这样吧，你回个短信给我，告诉我QQ吧，我加你</P>
<>不错啊，建网站不错，能促进建模发展</P>

是阿，我们理解需要处理的污水是在排放前就处理掉的

其实第一问我们在做的时候也没有什么头绪，但只我们队长用了一种比较先进的算法和软件，将所给的数据重新进行了分类，从而进行了定量的综合评价。

<>还有一点，我们在做地斯文的时候，只是考虑了处理污水的总量，并没有计算出在什么地点拍多少水。请问那文稿少可以指点一下。谢谢！</P>
