well-off consumption structure 小康型消费结构
Problems with high on-resistance that are seen in traditional vertical structure DMOSFET still appear in LDMOSFET and phenomena of turn-off delay and latch-up are seen in LIGBT as well.
传统垂直式dmosfet高导通电阻的缺点在LDMOSFET中依旧存在,而垂直式igbt关闭延迟和闩锁的现象,也在LIGBT中发生。
Well, imagine if that change in structure could be switched on and off by addition of a phosphorous; and in fact it can in many proteins.
那么,想象一下,只需引入磷酸基团,就能导致蛋白质的结构发生变化,事实上很多蛋白质就是如此
