In the magnetic fluid magnetic particle even distribution does in the liquid does not have the rule the Brownian movement, after sur- is parallel to the optical transmission direction gradient magnetic field, as a result of the magnetic field and the magnetic particle mutual function, the optical transmission rate can have the remarkable change.

磁性液体中的磁性微粒均匀的分布于液体之中做无规则的布朗运动，当外加1个平行于光透射方向的梯度磁场后，由于磁场和磁性微粒的相互作用，光透射率会发生显著变化，同样加垂直光路的磁场也会影响其光透射率。

An unmagnetic material which permanent magnetic distance and single electron are zero is selected as magnetic diluter system.

It uses the rheological characteristics of liquid-magnetic abrasive tool to finish surface of parts. It has typical fluidness when there is no external magnetic field around it. But when a strong magnetic field is applied, the viscosity of liquid-magnetic abrasive tool will increase quickly, and it will show the characteristics that resemble to solid.

该技术是利用液体磁性磨具的流变特性来实现对零件表面光整加工的，液体磁性磨具在没有外部磁场的情况下表现为一般的流体状态，具有良好的流动性，而一旦施加外部磁场它的粘度会迅速增加，表现出类似固体的特性，这就是液体磁性磨具的流变性。

Then it is gradually used to replace the optical encoder of a servomotor. However, the resolution of a magnetic encoder is not so good as that of an optical encoder. When the magnetic drum was magnetized the required pole pitch is needed very small in size, in order to satisfy the requirements of the resolution in a servomotor.

然而，磁性编码器的解析度尚不及光学式编码器，为了磁性编码器可满足伺服马达机构中所要求的解析度，因而当将磁性编码器内的磁环充磁时，其极间距必须尽可能地缩小，以使得可充磁的极数增加。

The operating range suitable for three-phase reaction was obtained and a mathematical model established. The results show that MSB formed by fine magnetizable powder and fliudizing flow can be operated stably in a wide range. MSB has three kinds of regimes: particulate, chain, and magnetically condensed. In these regimes, the chain regime is the best for three-phase reaction. When Ni-RE-P catalyst particles mixed with some iron powder, magnetically stabilization is easily achieved; therefore, it is possible that NiRE-P catalyst can be controlled in the bed for reaction more easilly if adding certain percentage of iron powder.

研究结果表明：细粉铁磁性颗粒形成的磁稳定床可在较宽流速范围内稳定操作，该磁稳定床有三种操作状态：散粒状态，链式状态和磁聚状态，其中有利于进行气液固三相反应的操作状态是链式状态；当磁稳定床在最小流化速度和带出速度之间操作时，床层处于链式状态；最小流化速度和带出速度可用（1-24）、（1-25）、（1-27）、（1-33）式计算；弱软磁性Ni-RE-P非晶催化剂中混入定量铁粉颗粒后便可形成磁稳定床，因此利用混入铁粉颗粒在外加磁场作用下控制弱磁性非晶催化剂颗粒进行反应的方法是可能的。

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。

From this study, it could be inferred that by connecting different bio-functional molecules to the MB, we can endue the compounds both abilities of bio-functional molecules and MB, which were the recognize ability and the super paramagnetism.

There are different content of Ni, Fe deposed on waste catalysts, which make them receive inequivalent force in magnetic field, catalysts with high content are selected from non- or lower magnetic active mass.

该磁分离方法主要是利用镍、铁等重金属元素在催化剂上沉积量的不同导致它们在磁场中所受的磁力大小不同，可从非磁性或弱磁性催化剂颗粒中选出吸附了较多金属的磁性催化剂颗粒。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.
