This article by Max Slater on differential programming does this particularly well.

Max Slater 撰写于微分文章这方面做得特别好。

They derived and solved the differential equation of pipeline deformation under high-fill conditions.

他们推导并求解了高填充条件下管道变形微分方。

Many differential equations students among you might enjoy thinking about how you solve this.

你们中许多微分方学生可能会喜欢思考如何解决这个问题。

To obtain the governing differential equations for the actual nodes near circumferential joints, virtual nodes are specially added near the joints.

为了获得圆周节附近实际节点控制微分方，节附近专门添加了虚拟节点。

Combining Equations (8), (9), and (17a, 17b, 17c, 17d), the governing differential equations of all actual nodes of the tunnel can be obtained.

结合方 （8）、（9） 和 （17a， 17b， 17c， 17d），可以得到隧道所有实际节点控制微分方。

An ordinary differential equation for the longitudinal deformation of an existing tunnel subjected to ground surcharge was established, and the analytical solution of the longitudinal deformation was obtained.

建立了地基附加作用下既有隧道纵向变形常微分方，得到了纵向变形解析解。

So if you could imagine all those differential equations that economists write down, with all the squiggles and the swirls, to say this is what's going to happen to the economy.

因此，如果你能想象经济学家写下所有微分方，以及所有曲线和漩涡，那么这就是经济将会发生情况。
