现在，虽然这一切听起来很简单，在理论上，明显有相当数量的实际问题之前，必须克服偏微分方程的工作，可建。

Now while this all sounds pretty simple in theory, there are clearly quite a number of practical problems to be overcome before a working PDE can be built.

你什么有效的偏微分方程做的是不断掀起一小负责高科技金属管内爆炸。

What you're effectively doing with a PDE is repeatedly setting off a small charge of hi-explosive inside a metal tube.

加州理工学院也纷纷发表自己的偏微分方程研究的一些优秀的信息。

CalTech have also published some excellent information on their own PDE research.
