As part of their natural defenses against viral infection, human cells have proteins that latch onto dsRNA, setting off a cascade of reactions that prevents the virus from replicating itself.
作为对病毒感染自然防御的部分，人类细胞的蛋白质会锁住dsRNA，引发级联反应，以阻止病毒的自我复制。
Clearing occurs as the held loop slips off the latch and onto the stem as the needle moves upwards.
在针向上运动时，被握持的线圈从针舌上滑到针杆上，为退圈。
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。
