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.

实时检测并联变压器一次侧的谐波电流，根据谐波补偿条件，得到谐波补偿电流的指令信号，通过电力电子变流器跟踪产生谐波补偿电流注入到二次侧补偿绕组中，使得并联变压器对谐波电流呈现近似为零的低阻抗，对基波电流呈现很大的一次侧自阻抗，从而输导系统中的谐波电流流入并联变压器支路。

He swung it once and twice and again.

他抡了一次，两次，又一次。

Methods From January 1988 to March 1999, 24 cases of congenital syndactyly were treated and classified by fusion tissue combined with the degree of fusion as follows:①simple complete syndactyly (4 cases).

结合并连的组织和程度分为：(1)单纯性完全性并指 4例，2指并指一次手术，3指并指分二次手术。(2 )单纯性不完全并指 9例，一次手术。(3 )复杂性完全并指 4例，分期手术。(4 )复杂性不完全并指 0例。(5 )复合性并指 7例，单纯行并指分指术。

Ma Yun points out when summary ABAC job: Our mainest 2008 job was to organize peak of medium and small businesses to meet, be in Hangzhou, be in Peruvian, gained huge success twice this.

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
