To introduce two kinds of temperature control modes and system composing for induction heating in oil tempered steel wire production line. The open loop control has bigger effect on the property of steel wire and its operation requirements are strict. 介绍油淬火回火钢丝生产线感应加热温度控制的2种方式及系统组成,开环控制对钢丝性能的影响较大,对操作要求严。
The radiation heat is mainly spent on the soil heating and evaporation in the forest, but mainly on the air heating and evaporation on the open ground. 林内得到的净辐射主要用于土壤增热与蒸发,林外得到的净辐射则主要用于空气增热与蒸发;
