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。

After introducing the basic knowledge of geometric algebra such as outer product,inner product and geometric product,this paper focused on the CGA description and computation with graphic reflection,rotation,translation,rigid body motion and screw motion,and gave the experimental demonstrations.

在简单介绍外积、内积和几何积等基本概念之后，重点论述了共形几何代数在图形反射、旋转、平移等变换和刚体运动、螺旋运动等方面的描述和计算方法，并给出了实验示例。

Depending on the axis being spacelike, timelike or null, there are three types of screw motions, the third case, i.e., cubic screw motion, is most particular because it is not a rotation together with a translation along the null axis, but a rotation together with a translation along a null curve with non-zero curvature.

依据旋转轴的向量类型，三维Minkowski空间中的螺旋运动可分为三类，其中第三类螺旋运动，即三次螺旋运动，是最特殊的。
