  1. Second, the selectivity depends on the Coulomb interaction on the surface, not the lipophilicity.
    第二,选择性只与表面的库伦作用力有关。
  2. The Coulomb-force in a star is equal to 3.4 octillion times of universal gravitation (neglect the effect of electricity charge tending to the surface).
    因为这个斥力也会比万有引力大3400亿亿亿倍(忽略电荷的趋肤效应)。

原声例句
可汗学院:生物化学

The charges we talk about when we talk about electrons and protons, those are the coulomb forces.

当我们谈论电子和质子时,我们谈论的电荷就是库仑力。

可汗学院:生物化学

Or in the case of electrons, when they get further away from a high energy state, the coulomb force is weaker, right?

或者就电子而言,当它们远离高能态时, 库仑力会变弱, 对吗?

库仑

库仑英语:Coulomb)是电量的单位,符号为C。若导线中载有1安培的稳定电流,则在1秒内通过导线横截面积的电量为1库仑。

库仑不是国际单位制基本单位,而是国际单位制导出单位。1库仑=1安培·秒(1C=1A\cdot s)。一个电子所带电荷量e=-1.6021892\times10^{-19}库仑,即1库仑相当于6.24146\times10^{18}个电子(约1.04\times10^{-5}mol电子)所带的电荷量。

1\ \mathrm{C} = 1\ \mathrm{A} \times 1\ \mathrm{s}

此单位是为纪念物理学家查尔斯·奥古斯丁·库仑而命名的。

1库仑亦可定义为:

1\ \mathrm{C} = 1\ \mathrm{V} \times 1\ \mathrm{F}

Coulomb 库仑

The coulomb (unit symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: Q or q) transported by a constant current of one ampere in one second:

Thus, it is also the amount of excess charge on a capacitor of one farad charged to a potential difference of one volt:
