The minimum possible density of the lunar atmosphere at the surface is shown to be essentially the value for the interplanetary medium. This value, when combined with the observed maximum, places the particle density between 10(3) and 10(6) per cubic centimeter, while the electron density must be about 10(3) to 10(4) per cubic centimeter. These results are markedly different from those recently obtained by Firsoff.
月球表面大气的最小可能密度显示基本上就是行星际介质的密度值。这个值与观测到的最大值相结合,使得粒子密度处于每立方厘米10³到10⁶之间,而电子密度必定约为每立方厘米10³到10⁴。这些结果与菲尔索夫最近得到的结果明显不同。
