Based on operation parameters of a three phase induction motor at duty type S1, this paper deduces the thermal state of this motor with constant output at duty type S7.

主要介绍一种依据一台三相异步电动机在S1工作制下的运行参数推断该台异步电动机容量不变时在S7工作制下发热情况的方法。

Thermal comfort exists if the human body in thermal equilibrium with its environment, implying a constant temperature of the body.

若人体与环境达成热平衡，以保持体温恒定，就谓之具有热舒适性。

Unlike large glass mirrors which are subject to the vagaries of humidity, thermal dynamics and constant deformation from gravity itself, liquid mercury which remains molten at room temperature can reflect as much as 75 percent of incoming starlight with little of the fuss associated with large conventional mirrors.
