用法例句

The results indicate that, even in case of high concentration of carbon dioxide, the flowmeter still maintains high measurement accuracy due to the techniques employed including zero-crossing detection of electrical level, averaging of multiple transit-time measurements randomly taken, and so forth.

文章设计了实验用以测试CO2的浓度含量对超声波气体流量计测量精度的影响,实验结果表明,由于在流量计中采用了"过零电平检测"、"随机多次测量声时后平均"等技术措施,即使在CO2的浓度较高的情况下,流量计依然可以保持在较高的测量精度。

A novel zero-voltage and zero-current switching (ZVZCS) three-level converter,and the drive circuit of the transistor were analyzed.

分析了一种新颖的零电压零电流 (ZVZCS)开关之电平变换器 ,以及功率晶体管的驱动电路。
