查询词典 ohm

The article focuses on the teaching of circuitry,from the basic concept,discusses the direction of the voltage or the electric current in different situations such as Ohm′s law,Kirchhoff′s law,Superposition theorem and so on.

结合在多年的教学，本文针对不同的情况电压和电流的方向做了探讨。1电流电压的实际方向和参考方向习惯上把电流的方向定义为正电荷运动的方向或负电荷运动的相反方向，而把电压的实际方向定义为电位降的方向。

On the basis of Ohm's and Kirchhoff's law, The mathematic model that can be used to caluculate the 3—D current distribution in alumina reduction cell was derived, and the computer program was compiled by finite differential method.

根据欧姆定律和基尔霍夫定律，用有限差分法导出了求解铝电解槽内三维电流分布的数学模型，编制了计算程序，在国内首次较准确地计算了铝电解槽内三。。。

If we use Ohm's Law we can calculate the voltage of this circuit at 12 volts .

如果我们使用欧姆定律，我们可以计算出这个电路的电压是12伏特。

For more information on the calculations please see the Ohm's Law page.

Note that Ohm's law holds true for DC as well as for AC circuits. However

要注意，欧姆定律不仅对直流电路有效，对交流电路也同样有效。

Given the voltage and the current, the resistance can be determined according to Ohm's Law.

已知电压和电流，根据欧姆定律，就可以求出电阻。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
