Ⅳ. 段落翻译 ⑴变压器的初级绕组是馈有交变电流的线圈，而次级绕 组是通过变化的磁通传给有功率的线圈。初级和次级 的名称只取决于变压器连接的方式；任一个绕组均可 是初级，于是另一个就是次级了。 译文：The primary winding of a transformer is the coil which is fed with an alternating current, and [或： while] the secondary winding is the coil to which power is transferred via the changing flux. The designations of the primary and the secondary depends only on how the transformer is connected; either winding may be the primary, and the other is then the secondary.

what is science 科技英语写作答案
what is science 科技英语写作答案First, then, what is science? Surely there can be no difficulty in answering this, and yet I fear that, if I should pass through this or any other audience with the question, I should get many different answers.A certain lady, whom I know better than any other, has told me that, should she ever be permitted to marry a second time, she would not marry a scientific man, because scientific men are so terribly accurate. I often hear the same general idea expressed, and it is clear that accuracy is one attribute of science according to prevailing opinions. But accuracy alone is not science. When we hear a game of baseball or of whist spoken of as thoroughly scientific, I suppose the idea here, too, is that the games are played accurately; that is, to use the technical expression, without errors.Again, there are those who seem to think that science is something that has been devised by the Evil One for the purpose of undermining religion. The idea is not so common as it was a few years ago, when the professors of scientific subjects in our colleges were generally objects of suspicion. The change which has come over the world in this respect within my ownmemory is simply astounding. In general terms, an agreement has been reached between those who represent religion and those who represent science. This agreement is certainly not final, but it gives us a modus vivendi, and the clash of arms is now rarely heard. Religion now takes into consideration the claims of science, and science recognizes the great fundamental truths of religion. Each should strengthen the other, and in time, no doubt, each will strengthen the other.。
