1. Thus electrons from external circuit must enter the device to neutralize the hole accumulation while the excess electrons inject from Emitter. The free electrons and holes accumulate at two sides of Emitter to change the continuity of band diagram for Base/Emitter junction and then attain high internal gain.
主要於基极/射极接面成长异质结构使得能带不连续形成能障，堆积由基极–集极吸收接面所激发之电洞，由基极–射极之能障高度的改变而由外部电路补偿额外电子於射极进而获得较高的电流增益。
2. The techniques of " grab start " and " hole enter " are the start techniques widely adopted from the seventies and eighties up to now.
抓台式起跳技术和洞式入水技术是七、八十年代至今广泛采用的游泳出发技术。
