Field emission currents were calculated for different apex radii at the gate voltage of 100v, and the results indicated that the field emission largely depends on the apex radius.
计算了在100V门电压下不同顶端半径的场致发射电流。结果显示，场发射对顶端半径有很强的依赖性。
The geometric feature of the arc finger seal is analysed. The relationship between the finger stick arc radius and the stick arc center circle radii and their value scope are determined too.
