In Europe, AC is usually generated at 50 Hz.欧洲的交流电输出频率通常为50赫兹。A measure of sound intensity equivalent to one decibel at 1000 Hz.一种声强的量度单位,其值等价于1000Hz1分贝.The frame rate is then 60 Hz.这时,帧速率为60赫....
The frame rate is then 60 Hz.这时,帧速率为60赫.In this paper a hybrid fuzzy - repetitive control scheme for 400 Hz constant - voltage constant - frequency ( CVCF ) inverters is presented.针对400Hz恒压恒频 ( CVCF ) 逆变器,提出了一种模糊 - 重复混合控...
