通过对摆辗加工中摆头与圆柱实心工件接触面积的分析，给出了计算其接触面积率的近似公式。
By analyzing the contact area between the Upper Die and cylindrical solid workpiece during Orbital Forming process, an approximate formula for calculating the contact area rate is proposed.
较低的封装分率下，组件壳程对流作用明显，有利于减少死区，充分利用膜接触面积。
Under low packing density, convection is significant in shell-side flow, which is preferable for the reduction of dead zone area and the higher utilization of contacting area.
本文考虑到接触面积大小的影响，并让四根探针排列成任意形状，导出了测量电阻率和薄层电阻的关系式。
In this article, we drive the equations of measuring resistivity and surface sheet resistance, taking into account the contact dimension and putting the location of the four probes arbitrary.
