On the basis of the plasma conditions in LEO. We adopt plasma thin sheath model and calculate ioncollection current.
本文根据LEO中等离子体温度低、密度高、德拜长度小的特点，采用薄鞘层近似，计算了离子收集电流；

The charge exchange and elastic collision between ion and neutral atoms and the collection and Coulomb scattering of ion on dust grains are considered.
Is located in the Julu County city industrial park, is the collection branch, the labor, the trade in a body "s large-scale specialized polymer lithium ion battery Manufacturer."
