热消散

In the 1930s, the Russian geochemist/biologist Vernadsky wrote,"The property of maximum expansion is inherent to living matter in the same manner as it is characteristic of heat to transfer from more heated to less heated bodies, of a soluble substance to dissolve in a solvent, and of a gas to dissipate in space."

1930年代，俄罗斯地理化学/生物学家沃尔纳德斯基写道："最大化扩张的属性是活物与生俱来的，就如同热之从温度较高的物体传到温度较低的物体，可溶性物质之溶入溶剂，以及气体之消散入天空。"

And the feasibility of the two measurement methods is demonstrated.3 Computer simulation is performed in the situation of air passing by a heating columned thermistor through a round pipeline. The fluid velocity and temperature distributions under different mass flowrate are shown. They reflect the impact the heating thermistor has on the fluid. The velocity distribution on the surface of the heating thermistor is studied and the impact of natural convection is revealed. The lower limit of measurement based on the simulation result is given.
