| 摘要: |
| 高速飞行器重返大气层时，在其表面形成高温等离子体鞘套，它在某一个飞行高度范围内会引起飞行器与地面之间的通讯中断，即“再入通讯中断问题”。目前国外减缓中断的手段较多，然而各有利弊。本文从原理上探讨了加电场减少鞘套边界层内电子密度方案的可能性，以期作为一种较简单的克服再入通讯中断的物理手段。 |

| The Research of Problem about Diminishing the Electronic Density in the Plasma Sheath by Using Electric Fields |

| Abstract: |
| When a high velocity vehicle reenters the atmosphere，its surface is Surrounded by a plasma sheath with high temperature. In the region of a certain altitude，the communication between the vehicle and the ground will be discontinued，which is the problem of communication discontinuity in reentry. Some methods to diminish discontinuity have been tested abroad; each of them has its advantages and disadvantages.This paper discusses the possibility to，diminish electronic density in the plasma sheath by using electric field. It is expected to be a simpler physic method for overcoming the communication discontinuity in reentry. |
