For example their understanding of the phenomenon of self-induction is not deep, so questions are often wrong, then they put out the fault in this matter and important topics together in practice and reflection, I found to know but did not understand the physical laws, to find a general way to answer this problem, such as from where to start with, what are the formula and so on.

比如们对自感现象理解不深，做题常常出错，那么就把们在这个问题上出过错的和重要的题目集中起来，在练习和思考中，发现知道但是并没有理解的物理规律，找到解答这种问题的一般途径，如从什么地方下手，用什么公式等等。

When the effect of inductance is such as to cause an induced voltage in the salne circuit in which the changing current is flowing, the term self-induction is applied to the phenomenon.

当电感效应在变化的电流流过的同一电路里足以引起感应电压时，我们就用"自感"这个词来描述这一现象。

When the effect of inductance is such as to cause an induced voltage in the salne circuit in which the changing current is flowing,the term self-induction is applied to the phenomenon.

当电感效应在变化的电流流过的同一电路里足以引起感应电压时，我们就用"自感"这个词来描述这一现象。（such as引导的不定式短语to cause。……表示结果。）转贴于：口译笔译考试

A phenomenon called self-induction is at work here: as the current oscillates, the magnetic field around the wire changes, too, inducing voltages that slow the oscillation.

这里运用了一种「自感现象」：当电流振盪时，金属线周围的磁场也会改变，产生使振盪减慢的电压。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
