| 1. | For proper operation the forward and reverse direction-control inputs must always be complementary .
要使计数器正常工作，正向和逆向控制输入电平必须始终相反。 |
| 2. | Special gain controls are used to regulate the amplitude levels at the beginning and end of the record .
为了调节记录的开头部分和尾端的振幅电平，通常采用专门的增益控制。 |
| 3. | Because the larger the event, the larger the number of oscillations of the transducer before they decay below the trigger level .
因为事件越大，传感器在它衰减到低于触发器电平之前的振荡次数越多。 |
| 4. | If this output does not switch between h and l anymore a hard-ware reset is produced and the processor is initialized again .
如这个输出不再在高电平和低电平间作切换，硬件复位就会产生，并将处理器再次初始化。 |
| 5. | The distance between the acoustic-emission source and the receiving transducer, and the background noise level are primary factors in selecting a particular frequency band .
声发射源与接收讯号传感器间的距离以及环境噪声的电平是选择频带的主要依据。 |
| 6. | Application of multilevel converter to power system
多电平技术在电力系统中的应用 |
| 7. | Four way high rf output , output level 110dbuv
四路独立高电平输出，输出电平110dbuv |
| 8. | Relative audio - frequency intermodulation product level
相对音频互调产物电平 |
| 9. | The full scale digital level of the digital audio equipments
数字音频设备的满度电平 |
| 10. | Television - measurement of luminance signal levels
