被动运输

被动运输的通路称离子通道，主动运输的离子载体称为离子泵。

Passive transport pathway was called ion channels , active transport vehicle was called ion pump of ions .

研究背景：离子通道是各种无机离子跨膜被动运输的通路。

Backgroud : Ion channels are all kinds of inorganic ions of passive transport across a cell membrane .

生物膜对无机离子的跨膜运输有被动运输（顺离子浓度梯度）和主动运输（逆离子浓度梯度）两种方式。

The passways of inorganic ions across the membrane have passive transport ( along the ion concentration gradient ) and active transport ( inverse ion concentration gradient ) .

用拉格朗日模型和滑移通量模型及将颗粒当作被动运输标量处理的方法对三维通风小室内颗粒的扩散分布进行了数值模拟，并将模拟结果与相关文献中的实验数据进行了对比。

3个种群酯酶基因多态性的产生可能是携带不同抗性酯酶基因的小菜蛾被动运输的结果；

It is not likely that esterase gene polymorphism of the diamondback moth with different resistance are comes from their migration between provinces , as living larvae and eggs of the diamondback moth often found on the transported vegetables .
