举一反三
- For a neutral-unearthing system, during a bolted single line-to-ground fault, the non-fault phase voltage and the fault phase voltage are ()respectively. A: phase voltage and zero B: phase voltage and line-to-line voltage C: line-to-line voltage and phase voltage D: line-to-line voltage and zero
- At first, the __________ of color pictures over a long distance seemed impossible, but, with painstaking efforts and at great expense, it became a reality. A: transaction B: transmission C: transformation D: transition
- WDM 波分复用（WDM，Wavelength Division Multiplexing）是指，在1根光纤上承载多个波长（信道）系统，将1根光纤转换为多条“虚拟”纤，每条虚拟纤独立工作在不同波长上。
- When the small dose of toxic drug mixing with several times the volume of diluents, we should use times mixing.
