英语翻译
When the heater was some distance above the floor and there was no air change in the room ,there was practically no convectional motion below the heater ,where the air temperature remained constant- On the other hand,above this level,a complex convective circulation was observed which led to a temperature rise throughout the space.If the heater was placed on the floor,the circulation reached right up to the ceiling.
Experiment shows the air temperature gradient (from floor to ceiling) when the heater was 0.75 and 1.75 m from the floor.It will be seen from the diagram that the position of the temperature jump moves with the source of heat.
