查询词典 magnetic

The above multiple changes will produce 2 kinds of waves, Matter waves and mechanical waves that spread at the same time. Because the electromagnetic wave is a matter wave, it is the medium. Since the multiple exchanges of the electrons state can be regarded as electrical vibration, and the vibrated electrons have magnetic fields and electrical fields at the same time, the electromagnetic wave will be produced. Then, because the electron itself is a matter micro particle, it can produce mechanical waves which can propagate outside with electrical magnetic waves.

这种状态改变的多次往复，就会产生两种波，一种物质波，即电磁波；一种机械波，并且这种机械波是以同次产生的电磁波为媒质进行传播的，，这是因为本种状态的多次往复，可以看作是一种电子振动，振动的电子同时具有磁场和电场，所以能够产生电磁波，又因为电子本身是一个物质微粒所以他能够产生机械波，并且是横波，并随电磁波进行向外传播。

分析了传统卧式往复压缩机活塞连杆运动的规律，设计了一种集磁悬浮和线性驱动技术为一体的往复磁悬浮式压缩机机构，该机构利用作用于活塞连杆上的磁场力，使其力偶矩与连杆活塞的重力矩相平衡，使活塞对缸体的正压力趋向于零或等于零的理想状态，从而使摩擦副间的摩擦力达到最小。

Owing to the drawbacks of analytical shimming, this paper puts forward the concept of passive numerical shimming for searching a method of compensating Bz'easily to a high level and with a low cost. Based on the magnetic field caused by a magnetic moment, the distribution of moments in a superconducting NMR imaging megnet can be determined through some pseudoinversion algorithm directly from Bz'. The moments are used to compensate Bz'.

无源数值匀场的出发点直接是不均匀磁场的磁场偏差B〓本身；无源数值匀场的基础为磁性材料的磁矩所产生的磁场；由已知B〓，通过某种逆运算，确定磁性材料的磁矩在主磁体中的分布，实施此分布，以磁性材料的磁矩所产生的磁场直接对B〓进行补偿——这便是本文提出的无源数值匀场的概念。
