单词 Electron Charge
释义

Electron Charge

原声例句
CNN 10 学生英语 2018年11月合集

When energized wires strip negatively charged electrons from the air ionizing the molecules that move toward negatively charged electrodes at the planes tale.

当能量形成的导线剥离空气中带负电荷的电子时,就使平面上朝着带负电荷的电极移动的分子成为电离。

可汗学院:生物化学

Well, I said it's neutral, so the proton has an equal positive charge as the electron's negative charge.

好吧,我说它是中性的,所以质子的正电荷与电子的负电荷相等。

It traps electrons, or charges for years on end, and in order to read the information, the electron charge level is measured, and the amount of charge on the charge trap is unchanged.

它会连续多年捕获电子或电荷,为了读取信息,需要测量电子电荷水平,而电荷陷阱上的电荷量是不变的。

科技智慧坊

However, in order to erase the contents of a memory cell, all the electron charges are forcibly removed from the charge trap returning it to its lowest level, which is 1-1-1, and leaving no excess electron charges behind.

然而,为了擦除存储单元的内容物,所有电子电荷都被强行从电荷阱中去除, 使其恢复到最低水平,即 1-1-1, 并且不会留下多余的电子电荷。

基本电荷 Elementary charge

(重定向自Electron Charge)

基本电荷e,是一个质子所带的电荷,或一个电子所带的负电荷的量。它是一个基本物理常数,是原子单位和一些其它自然单位制中的电荷单位。

根据国际科学技术数据委员会所公布e的值,基本电荷的值大约为

在高斯单位制中,它的值为

自从1909年罗伯特·密立根的油滴实验中测量出基本电荷后,人们便认为它不可再分了。1960年发现了夸克,它们的电荷为3e3e,所以把“基本电荷”用来指电子的电荷便不完全正确了;然而单独的夸克至今没有探测到,都是两个以上的夸克聚集在一起,使得总电荷为基本电荷的整数倍。

Elementary charge 基本电荷

(重定向自Electron Charge)

The elementary charge, usually denoted as e or sometimes q, is the electric charge carried by a single proton, or equivalently, the magnitude of the electric charge carried by a single electron, which has charge e. This elementary charge is a fundamental physical constant. To avoid confusion over its sign, e is sometimes called the elementary positive charge. This charge has a measured value of approximately 1.6021766208(98)×10coulombs. In the cgs system, e is 4.80320425(10)×10 statcoulombs.
