查询词典 magnet

Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.

法拉第定律指导体环路里的磁通量发生变化时，在导体环路上产生电动势，而且服从围线积分律；麦克斯韦旋度理论指以太空间某点的磁场强度发生变化时，在以太空间的该点产生电场，即大家熟知的自由空间里"电场生磁场与磁场生电场"之互生场理论，而且服从微分律；洛伦兹磁力指金属电子切割磁力线时，金属电子受力沿着导体漂移而形成感应电流，其实，无论线圈运动或是磁铁运动，只要磁场与导体存在相对运动，则金属电子必然切割磁力线，即，"线圈静止而磁铁向左运动"与"磁铁静止而线圈向右运动"这两种情况是一样的，都属于金属电子切割了磁力线。

A magnet is a piece of iron which can pull other pieces of iron to itself.

从带有定语从句的表语，就可以清楚地理解magnet的意思是"磁铁"了。

Stoner metal could be campy and self-aware, messily evocative, or unabashedly retro; in any case, bands like Monster Magnet and Kyuss were perfect fits for the eclectic tastes of the early-'90s alternative metal movement.

Stoner metal 可以是装模作样而有自知之明的，能够唤起污秽与零乱的，甚或是一种泰然自若的对以往的回顾。无论如何，像 Monster Magnet 和 Kyuss 那样的乐队，完美地契合了90年代早期另类金属运动的电子乐口味。

主要常见产品有扁平电机磁钢，空心杯磁钢，UCM磁钢，手机受话器磁钢，核磁共振磁钢等等各类电子产品零配件；橡塑磁有磁片/裱pvc/双面胶、异性橡塑磁、橡塑软磁片、挤出磁条/裱双面胶、磁性打印纸等，产品可直接在无磁面上印刷或在裱在无磁面上的pvc上印刷、无磁面裱双面胶（这种产品客户可自己加工，比如贴彩纸），另外一面是充磁面，它直接可粘在带铁的东西上面(比如汽车、冰箱、或展架等)，使用起来比较方便、简单。

In MRI system, magnet system is the main part that generates imaging magnetic field. Its performance is an important factor to affect image quality. Therefore, the research on methods for magnet system has important theoretical and applied values. Magnet system is mainly composed of magnet and shimming component.

在磁共振成像设备中磁体系统是一个重要的组成部分，负责产生均匀静磁场，为磁共振成像提供基础物理环境，其性能的优劣是决定磁共振图像质量的重要因素，也是衡量整个成像系统性能的主要参考指标，因此具有重要的研究意义。
