We have fabricated and tested high-T SQUID planar gradiometer patterned from YBCO thin film deposited on a SrTiO3 bicrystal substrate.

我们在10×10平方公厘的SrTiO3双晶基片上，设计并制备了YBCO双晶结dc-SQUID一阶平面式梯度计。

This system consists of a light source chamber, a grating spectrometer, a DC voltage regulator and a piampere current meter.

该系统由专用光源室、光栅光谱仪、直流稳压电源、皮安电流计4部分构成。

However, this modulation mode would not prevent the injection of DC current into the grid.

在双极性脉宽调制方式下，全桥逆变器的共模电压恒定，不产生共模电流。

The DC/AC inverter performs MPPT and delivers low distortion output current to the grid.

直流/交流逆变器演奏的MPPT和提供低失真的输出电流，以网格。

Anyway, I figured it was DC on the AC line, Ground loop, etc...

不管怎样，我想这是特区的AC线，接地环路，等等。。。

Using DC and AC poling methods, three groups of polarized PZT/P 70/30composites have been prepared by poling only the ceramic phase(1), both ceramic and polymerphases in the same(2) and opposite(3) directions. Piezoelectric coefficients of group 1 compositesincrease as the PZT content increasing, while for group 2 composites, the piezoelectric coefficientschange the sign with increasing PZT content because piezoelectricity of copolymer is increasinglycompensated by that of PZT, and PZT content for zero-〓 isn't that for zero-〓. The experimentdata of both group 1 and 2 composites agree well with EMT-Shin model.

对复合材料的压电性能：只极化PZT粒子相的复合材料的压电系数随陶瓷分数的增大而增大，PZT粒子相与共聚物基体同向极化的复合材料的压电系数由于两相效应的部分抵消，随陶瓷含量的增大，发生符号的改变，且〓和〓零点不重合，它们与EMT-Shin模型都符合较好；而两相反向极化的复合材料的压电系数由于AC反向极化会导致陶瓷相极化程度的下降，导致实验值和理论预期偏差较大，尤其在PZT粒子高含量区。

According to Sigma, its GTE prototype is more innovative than other offerings on the market due to its twin DC motor design.

根据六西格玛，其肾小球原型更具创新性比其他产品在市场上由于其双直流电动机设计。

Specially, in allusion to winding"s DC resistance test, a measure named gyrator is promoted which realized the resistance"s fast and accuracy test.

特别针对绕组直流电阻测试，提出了用"回转器法"实现绕组的直流电阻的快速、准确测试。

Unless Micheletti does something incredibly outrageous or stupid, I still think he has won this," says Peter Hakim, of Inter-American Dialogue, a think-tank in Washington, DC."

除非Roberto Micheletti做出某些不可思议或愚蠢的事情，我仍认为他会是赢家」，华府智库「美洲对话」的Peter Hakim表示。
