I want to point out three methods I noticed Ghostbusters using.

我想指出我注意到捉鬼敢死队使用的三种方法。

Since this work uses the material point method, which is a hybrid simulation technique that uses both particles and grids, the delta x row denotes the resolution of the simulation grid.

这项工作使用了“物质点法”，即一种同时使用粒子和网格的混合仿真技术，Δx行表示模拟网格的分辨率。
