频率转换

The designed controller can operate at fixed frequency without an internal oscillator,which has better output voltage ripple.

AOT控制保证了转换器在无需内部振荡器的条件下，工作于固定频率脉冲宽度调制模式，并改善了输出电压的纹波特性。

We get the relations of system frequency, load resistance and electromechanical coupling coefficient to the conversion efficiency of piezoelectric transducer.

经过分析讨论后，得到了压电发电系统的工作频率、负载电阻和机电耦合系数与压电换能器能量转换效率的关系。

The lead-in voltage and out-of-line voltage of switchbox are detected and converted into frequency signal. The arc voltage signal can be obtained by measuring the two signals. The arc voltage signal and arc light intensity signal are sent to the advanced single-chip microcom puter, PIC16F877, to do synthetic analysis – judgment.

提取配电箱的进线电压和出线电压，分别转换成频率信号进行比较，获得电弧电压信号，并将其和弧光信号一起送入性能先进的PIC16F877单片机，做综合分析判断。

Seismic amplitudes can be correlated to log lithologies using 90°-phased seismic data, and, consequently, seismic traces can be interpreted as wireline lithologic logs.

地震沉积学在高频率层序和沉积体系研究中有着特殊的优势。90°相位地震资料的振幅可以和岩性测井曲线对应，对地震资料进行90°相位转换后可以通过地震振幅分析岩相。

Finally, it is easy to move form the Laplace domain into frequency domain.

最后，从拉氏域转换到频率域也很容易。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
