- 1
The density, mass, and size compare favorably to that of Earth. But, the atmosphere and surface features differ markedly. 它密度、质量和大小都和地球差不多，但大气和表面却截然不同。 - 2
The variation of the mass loss, packing density, surface area, distribution of pore diameter, amount of ash with the cyclical Numbers were researched. 考察了活性炭的失重率、堆密度、比表面、孔径分布及灰分含量随活化次数的增加而变化的情况。 - 3
This difference in surface gravity is due to a number of factors - mass, density, and radius being the foremost. 地表重力的差异源于很多因素的影响——质量，密度，半径(这是最重要的因素)。
