net loss of heat的意思|示意

Results showed that the net heat loss on the downstream side of the jet nozzle could reach 20 ~ 30% of total heat flux. Therefore it can not be neglected in calculating the wall temperature.

结果表明，喷管下游端的壁面辐射损失高达壁面总热流的20 ~ 30%，在壁温计算时不容忽略。

Thermal heat loss tends to be used to express the net thermal efficiency of insulation effect.

热损失一般用热网热效率来表示其保温效果。
