cold hardening 加工硬化。

cold hardiness

During the winding of magnetic pole coils used in synchronous electric motors , cold hardening is induced by press bending at 90 , by which the coils are hard to be pressed and shaped , thus local resistivity increases and results in influence on the coil lifetime 摘要同步電動機磁極線圈在編繞加工時, 90角處因壓彎而產生的冷作硬化現象使線圈無法裝壓成型,且局部電阻率增大,甚至影響磁極線圈使用壽命。

Cold hardening ( cold acclimation ) processes taking place in plants before the onset of winter that prepare them to withstand low temperatures 低溫鍛煉(低溫馴化) :在冬季來臨之前植物體內發生的一些生理變化,目的是為了經受即將來臨的低溫。
