After spring foundation are used for the turbine generator units the dynamic load is isolated and vacuum suction eliminated, which has greatly reduced the sectional size of the column.

该电厂汽轮发电机组使用了弹簧基础后，既隔离了动载荷，又消除了真空吸力，大大减小了立柱截面尺寸。

In addition to that, we have that epsilon nought value, remember that's the permittivity constant in a vacuum, and basically that is what we use as a conversion factor to get from units. We don't want namely coulombs to units, we want that will allow us to cancel out in this equation.

这是电子的电荷，此外，我们有epsilon零，记住这是真空的介电常数，这是我们用来转换单位的转换常数,我们不想用库伦单位，我们希望这个可以在方程中约去它。
