查询词典 erratic current

This thesis chooses B spline wavelet that adapts to the analysis of power system signal, and uses the wavelet transformer to analyze the magnetizing inrush current and inner fault current.

而小波变换具有多尺度分析和良好时频域局部化分析特性，适合提取信号边缘和峰值突变的特征，能够很好的检测信号奇异性。

The waveform of differential current in each data window is divided into four parts averagely according to time, and the area-ratio among the four parts can be used to distinguish magnetizing inrush from internal fault current.

该算法以工频一周波为数据窗长，将数据窗内的差流波形按时间均分为4份，根据各份面积之间的比值来识别励磁涌流和内部故障电流。

In the transformer differential protection, it is a congenital and difficult problem that cant be avoided how to distinguish the magnetizing inrush current with the internal fault current. It has become the focus studied for many years. The existing transformer protection principles all have certain defects and the main reason lies in inadequate understand of the transformer fault mechanism.

在变压器差动保护中，如何区分励磁涌流与内部故障电流是一个先天性的、不可回避的难题，多年来一直成为研究的热点，而且现有的变压器保护原理也都存在一定的缺陷，其主要原因在于对变压器内部故障的机理认识不够。

Part One Research on Measuring of Resistive Current Passing Through XLPE Cable With Applying AC Voltage: By many tests,It is found that mains frequency is not sensitive to the mechanical fault of power cable main insulation.Accordingly,a new method that the fault of power cable main insulation is measured by measuring the resistance component of leakage current is put forward.

第一部分对XLPE 电力电缆施加工频交流电压时阻性电流的检测研究：通过大量的试验发现工频交流耐压试验对电力电缆主绝缘的机械损伤不灵敏，从而提出了通过检测泄漏电流的阻性分量来检测电力电缆主绝缘缺陷的新方法。

就模型本身而言还需进一步的完善，最新的研究发现在许多种属的心肌细胞中Ik都有两种成分Ikr与Iks［4～6］，这无疑将使对Ik的理解更全面和完善。

An extremely high temperature of anode humidification is also unreasonable; as a result, when the current density is high, the liquid water should be injected directly into anode gas channel to guarantee both high inlet H〓 concentration and well-humidified membrane. 4. The utilization of Pt in the cathode catalyst layer will decrease with the increasing current density; as a result, based on the principle of maximal Pt utilization, the catalyst layer can be designed much thinner or not uniformly in the catalyst distribution.

而在此截面上，交指型流场燃料电池阳极侧的液态水饱和度的极值位置并不确定；在电池阴极处，液态水饱和度的极值总是出现在z=0.002m处的气体扩散层和膜的界面上，并且该处的液态水饱和度沿x方向存在一个最大值，与此相应的氧气的质量浓度分数在该处达到极小值，因此极限电流密度将首相出现该处，但总体来说液态水饱和度沿x方向的分布较为均匀。4。

Under the terms of the contract, ABB will add one additional high-voltage regulating transformer (rectiformer, used to convert alternating current to direct current) rated at 100 megavolt amperes, to increase capacity in two smelting potlines.

根据合同条款，ABB将添加另外一个额定100兆伏安倍的高压调节变压器（整流变压器，用来把交流电转换为直流电），以增加两个冶炼电解电池列的产能。

Your current school network account will remain active only until the end of the Michaelmas Term, following which your access to the school main server, current email account and any personal web space you may have will be closed.

意思相同，因此，同第3题一样，这道题也是同义词替换，问题句只是用不同的词汇对原文进行了paraphrase。所以，问句与原文意思相符，应该选择T。

Tom: You are right, he worked hard all the time.

你是对的。他一直都是努力工作。

Take shortcomings,failures,and mockings of others as commonplace and a drive to complete oneself,hold your own opinion over the evalution and disscution divested from others,afterwards sink into the state of eliminate mistakes if any or encourge oneself being not being influenced by the sayinngs of others or having no ideas to do.

把缺点、失败及别人的耻笑等看成是一种常事，当成完善自己的动力，对别人的评价和议论自己心中有主见，做到&有则改之，无则加勉&，不为人言所左右或无所适从。
