分析了大量缺陷漏磁场数据，选取了量化缺陷外形的漏磁场特征，给出了缺陷外形和漏磁场特征的关系曲线。

Effect of SMF on Microorganisms (1) The influences of magnetic induction in SMF on microorganisms were studied.

以细菌、酵母和霉菌为对象，研究液体中不同强度静态磁场对微生物的影响，获得磁场作用24h后微生物的存活率与磁场磁感强度的拟合方程如下：(1)啤酒酵母〓(2)黑曲霉〓(3)枯草杆菌〓 2。

We got that,the charged particles be binded in this field,and canonly move along the magnetic line of force as spiral motion and the positive charges andnegative charges moved in opposite direction which be fromed the big molecular groups thatbe hardly absorption,by means of incrustation preventing.

讨论了轴对称非均匀磁场对带电粒子的作用，分析了"磁约束"对防垢、除垢的微观机理，指出满足磁约束理论的轴对称非均匀磁场的防垢，除垢效果好的原因，正是由于在这种磁场中，带电粒子的运动被约束在一定磁面上的某一磁感应线附近做以该磁感应线为中心的螺旋运动，且正、负离子的回旋方向相反，从而形成内部相互作用较弱的大分子簇团不易吸附在管壁上，达到防垢目的；磁化水的渗透压较大，可起到除垢效果。
