此外，由于气体的分子运动依赖于温度，在木星行星的低温下，即使是最轻的气体也不可能获得逃逸所需的速度。
Also, because the molecular motion of a gas depends on temperature, at the low temperatures of the Jovian planets even the lightest gases are unlikely to acquire the speed needed to escape.
温度表置放于远离障碍物的百叶箱中，以便取得自由运动空气的标准值。
Thermometers are placed in shelters far away from obstacles so as to get free-moving air standard values.
物体温度升高后就会辐射出热量，但由于原子的无规则热运动，在物体表面附近还会产生电场。
As an object heats up it radiates heat, but it also generates an electric field near its surface as a result of the random thermal motion of its atoms.
