Admittedly, at an average density of 100-1,000 molecules per cubic centimetre ( compared with 100 billion billion in air at sea level), it is a pretty thin gas. 诚然,分子平均密度10^2-10^3/cm^3的气体非常稀薄(海平面处是10^26/cm^3)。
The analysis is based on a cubic centimetre of soil scooped up by the lander's robotic arm and introduced into one of its eight ovens, where it was gradually heated to1000C. 探测器机器手臂在火星上挖掘了一立方厘米土壤并将其放入烤炉,在那里逐渐被加热到摄氏千度。在此基础上对土壤做出分析。
