quasi-fermi levels造句

• Because quasi - fermi levels of a laser diode ( ld ) vary with the carrier density , it is predicted that a new type of hysteresis loop should occur for the current passing ld while a hysteresis loop appears on the power - frequency curve of the ecld . an explicit analytical expression for the frequency width of the hysteresis loop and the condition for the formation of the hysreresis loop has been deduced
  预测了由于半导体激光二极管( ld )的准费米能级之差随ld内线流子密度的变化而变化，因而，在调谐外腔半导体激光器的输出功率?振荡频率曲线上出现双稳环的时候，通过ld的电流也应出现一个伴随的新型双稳环? ?电流双稳环。
