Water cannot resist(反抗) a pressure(压力) exerted on it in only one direction, the way, for example, a block of steel(钢块) can when it resists being squeezed(挤压) in a vise(台钳).
举一反三

- Taking hollow fiber membrane module as an example, according to the way of water inflow, it can be classified as outside-in type: raw water enters from the outside of membrane, and purified water flows out from the inside of membrane. On the contrary, it is inside-out type. The working pressure of the inside-out type is higher than that of the outside-in type.
