常見(jiàn)例句雙語(yǔ)例句In typical operation, the emitter–base junction is forward biased and the base–collector junction is reverse biased.在正常工作中，發(fā)射結(jié)正向偏置，基集電結(jié)反向偏置。At constant bias current, the simulation shows significant enhancement in optical bandwidth due to moving the quantum well in the direction of collector-base junction.模擬表明，在恒定的偏置電流下，沿集電結(jié)方向移動(dòng)量子阱能顯著提高光學(xué)帶寬。Regardless of type NPN or PNP-type tubes, the internal transistor has three areas, namely, the launch area , base, collector area, the three areas form two PN junction.無(wú)論NPN型還是PNP型管，三極管內(nèi)部均有三個(gè)區(qū)、即發(fā)射區(qū)、基區(qū)、集電區(qū)，三個(gè)區(qū)形成兩個(gè)PN結(jié)。 返回 base collector junction
