1、The effects of stoichiometric proportion and ambient gas on crystal SiC, especially on the defects of SiC, were analyzed.
2、When a massive proto-star approaches the main sequence, its surface temperature is low and it can not ionize the ambient gas.
3、The study of burning under the influence of small amplitude disturbances in ambient gas is a logical starting point for understanding the unsteady burning phenomena.
4、The model has been used to investigate the influence of different laser irradiance and ambient gas pressure on the laser ablation and the expansion of plume.
5、And the ejection into ambient gas of one thousandth atmosphere or so is special, the 'snowplow' phenomenon is observed and the plume plasma splits into fast_ and slow_moving parts.
