simple cast-on

I like the following way because it's simple and straightforward. It focuses on four personality types — and I think it describes the cast of characters running around this planet pretty well.

我喜欢下面的这种方式，因为它简单明了。

Dilute solutions of a simple, coil-like polymer in a volatile solvent are cast on a glass slide in the presence of moist air flowing across the surface.

简单的无规线团状态聚合物溶解在挥发性的溶剂配置成稀溶液，在有潮湿空气在表面流动时浇铸到玻璃片上。

In the scene with the ground I used the simple wall object to cast shadow on it.

我在这个场景中的草坪中用了简单的墙壁贴图在给他投了影子。
