对共振和非共振情形下尾波场效应与相对论效应对强激光脉冲在稀薄等离子体中传输的影响作了详细比较。
The relativistic effect and wakefield effect on the propagation of an intense laser pulse in plasma are compared in the resonant and non-resonant cases in detail.
同时发现在稀薄等离子体中激发的尾波势场与等离子体的密度几乎无关，而激发的尾波场最大电场强度与等离子体的密度有关。
In rare plasma, the strength of the wake-field depends on the background plasma density, while the maximum wake potential of wake-field is dependent on it.
日冕的电离气体（又叫等离子体）不仅非常炙热，而且异常稀薄，其密度还不到组成太阳主体的氢气密度的十亿分之一。
As well as being very hot, the ionised gas of the corona (called plasma) has a superthin consistency. It is less than a billionth of the density of the hydrogen that makes up the main ball of the Sun.
