在实际中,我们定义,效率为热与功的比值。
And in practical terms, we can define the efficiency as the ratio of the heat in to the work out.
振荡气体与板叠表面热交换进行声功泵热,系统通过板叠的冷、热端换热器与外界交换热量。
The heat is transferred between the oscillating gas and the surface of the stack and is pumped from the cold to the hot end.
结果表明:X70管线钢焊接接头热影响区冲击试样的冲击功与断口剪切面积基本成线性比例关系,冲击功越高,剪切面积越大。
The results indicated that impact absorbed energy of heat-affected zone in welded joint of X70 pipeline steel were proportional with shearing area on the whole.
