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100 V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。

Output powers and beam quality factors M2 are measured under two different coiling radii. 217 W with M2 of 2.96 can be obtained for coiling radius of 165 mm and 160 W with M2 of 1.38 for 52 mm.

将光纤缠绕至两种不同半径，实验测量了相应条件下激光器的输出功率和光束质量因子M2。缠绕半径为165mm时，输出功率为217W，M2为2.96；缠绕半径为52mm时，输出功率为160W，M2为1.38。

r+ And let's say that sodium has a radius, r plus, r- and chlorine has a radius, r minus, when r is very large in comparison to the radii of the ions, I don't need to draw them this way.

让我们假设钠有半径，是，氯也有半径，是，当r比离子半径大很多的时候，我不需要这样来描述。
