Development of ac - switch voltage current frequency adj - ustable power amplifier 交流开关式电压电流频率可调功率放大器的研制
We found that the visible light - induced switching voltage decreases about 70 % at maximum with intensity increasing 并实现了利用可见光对晶体畴反转进行可控操作和实时监测。
But majumdar explains they dropped the switching voltage to a sufficiently low one volt by thinning the channel walls 但马强达说明,他们在通道壁减薄后,已将开关电压降低至一伏特。
The relation of light intensity and the domain switching voltage of the near - stoichiometric mg - doped lithium niobate was studied 摘要研究了在可见光诱导条件下的近化学计量比掺镁铌酸锂的反转电压与光强之间的关系。
