在NX内没有逆求曲线的功能，因为NX无法知道你的原点及起始点是什么，也不知道你的X，Y的方向。如果你想要做出此曲线的方程，或者说这个曲线的解析式，必须使用其他软件来做：
1、将NX中的曲线给定一个坐标系；
4 Z& L, X% T% ^  K2、将曲上尽量多的点的坐标求出；
3、将这个点的坐标做成数组矩阵，放到Matlab软件中，使用离散点，做曲线拟合。
' L1 h, z- |! Y这样可以得到一个很接近原来曲线的曲线方程，可能这是一个比较好的办法；

偶然看到神舟又在促销1999元的Jewelry笔记本，并保证说不是上网本，仔细一看配置，呵呵，居然同我5年前的asus mp4 player爱本S5000差不多。
cpu、硬盘、内存、屏幕大小都差不多，除了芯片组比我的intel915 wholesale mp4略差之外，而我的s5000 china phone，2004年9000大洋买的，现在居然又以2000元的价格出新版，真是经典中的经典啊！！
