查询词典 harmonic analyzer

In this condition, the parallel transformer can exhibit nearly zero impedance to harmonic current and very high primary self-impedance to fundamental current and thus lead harmonic current in power systems to flow into the transformer branch. With a step-down transformer, the power semiconductor switches of the active power filter are always worked in relatively low voltage, which ensure the security and reliability of the active filtering device.

然后详细地介绍了三相铁磁谐振电路，对其所产生的谐波谐振、基波谐振、分频谐波谐振建模，做了进一步的分析。

Total harmonic distortion, another ADC specification you need to watch, is the ratio of the rms sum of the powers of the harmonic components, or spurs, to the input-signal power

总谐波失真，另一个要注意的ADC指标，定义为谐波成分的均方根和，或者是输入信号功率的比值

Toccata reveals a mixed image, having in mind the style imitations, and rasembles toccatas of 20th sentury - from the music of Bartok, Stravinski, Prokofiev's harmonic style, Pancho Vladigerov's texture and harmonic originality, and even Chopin's etudes texture.

托卡塔揭示了一个混合的图像，同时具有风格的模仿，并rasembles20香榭舍托卡塔-从音乐的巴托克，斯特拉文斯基，普罗科菲耶夫的谐波风格，潘乔Vladigerov的质地和谐波原创性，甚至肖邦的练习曲纹理。

Every tonality we hear has a different harmonic structure, and that harmonic structure changes over time.

通过对电网谐波和瞬时无功功率理论在谐波检测中应用的分析研究，作者给出了基于瞬时无功功率理论的检测方法在电网电压不对称、存在畸变时的电流检测方法。

The electron beam current measured by the beam current monitor (BCT3) is almost in direct proportion to the induced voltage of the fundamental harmonic. When the parameters of the pre-buncher and buncher are adjusted greatly while the beam current being unchanged, the fifth harmonic signal has a great change, but the fundamental signal changes gently. The test results are all in good agreement with the theoretic analysis.

根据不同时刻的记录，基频腔峰值电压与束流流强探测器BCT3所测流强值近似成正比关系；当大幅改变预聚束器和聚束器参数而束流流强不变时，反映聚束质量的五倍频腔信号也随之大幅改变，而反映流强信号的基频腔信号则变化不大，这些试验结果与理论分析完全一致。
