Magnetic working substance area is circular arc with certain radialthickness, and has certain gap with stator permanent magnetism block.
磁工质区域为圆弧形，有一定的径向厚度，与定子永磁块间留有一定的间隙。
2
The test consists of locating the gaps in a graduated series of sizes of incomplete rings whose radialthickness and gap are equal to one-fifth the diameter of the ring.
这种测试由固定的分等级系列的不完整环的间隙组成，这些环的径向厚度和间隙为环的直径的五分之一。

There are a lot of mode wave patterns near P-wave velocity line in 2-D spectrum, which have dense special distribution and large amplitude when the radialthickness of model well is thicker ;
