另外一个小组则同时学习4个方程序，一组例题同时包括4种计算的类型习题。

The other half studied mixed problem sets, which included examples all four types of calculations grouped together.

而且，我们也会让第三方程序员能轻而易举地在系统中加入他们自己的对象类型。

But we'll also make it easy for third-party programmers to add their own object types to the system.

这些方程可以使用大范围的参数和属性，它们可以让你创建很多不同类型的约束。

The wide range of parameters and attributes available to these equations lets you create many different types of constraints.

You won't have to solve it in this class, you can wait till you get to 18.03 to start solving these types of differential equations, and hopefully, you'll all want the pleasure of actually solving the Schrodinger equation at some point. So, just keep taking chemistry, 18 03 you'll already have had 18.03 by that point and you'll have the opportunity to do that.

你们不用在课堂上就解它，你们可以等到得到18，03之后,再开始解这些类型的微分方程，希望你们都想得到,实际解薛定谔方程的乐趣,所以，保持来上化学课，你们在那个点将会得到,你们有机会做到的。
