However, these advantages may be outweighed by the flow restriction the element creates in the intakeline and the negative effect this has on pump life.
但是问题是滤芯会对吸入管线中流量造成限制，泵的寿命也会收到影响。

The maximum resistance allowances of the intake system and air filter are gained for the D9-220 engine. This provides a basis for the intakeline design and the air filter selection of the engine.
得到D9-220柴油机进气系统和空滤器的最大阻力限值，为进气管路的设计和空滤器的选择提供了依据。

The most promising line of all, though, is to control an animal's intake of iron.
