electric charge 電荷。

electric circuit

This paper intends to illustrate by the calculation of concrete examples that conductors are different in their electric charge intensity although they are identical in their surface curvature 摘要通過具體實例計算表明,在靜電平衡的條件下導體表面雖然曲率相同,但電荷面密度卻不一定相同。

Matter and antimatter are perfect opposites ; for each of the basic particles of matter , there exists an antiparticle , in which properties such as the electric charge are reversed 物質和反物質是理想的對立事物;對于每一種基本物質粒子而言,存在一種反粒子,它具有象電荷顛倒那樣的特性。

Defining “ similar ” with regard to amino acids can be complex : the 20 amino acids differ from one another in all sorts of properties , from size to shape to electric charge 要定義相似的胺基酸,恐怕是很復雜的事情,因為20種胺基酸的特性,無論是分子大小、形狀或電荷都各不相同。

Kirchhoff ' s current law is applied to describe the relationship of branch currents that flow into or out a same node and it reveals the essential law of conservation of electric charges 基爾霍夫電流定律用來描述流入或流出同一個節點支路電流的關系;它揭示了電荷守恒定律的本質。

That ' s why a lightning bolt striking an airplane is unlikely to take the airplane down ; the aircraft will distribute the electric charge over its entire surface , protecting what ' s inside 這就是為什么閃電擊中飛機,飛機不會掉下去,飛機將電荷分布到整個飛機的表面,保護了內部。

This machine shatters tiny amounts of a sample into its component atoms , ionises those atoms in order to give them an electric charge , and then uses that charge to attract the atoms along a tube 這個機器將微量樣品粉碎成原子,電離化使其帶電荷,然后順著管道利用電荷吸引原子。

A hypothetical particle postulated to be the quantum of gravitational interaction and presumed to have an indefinitely long lifetime , zero electric charge , and zero rest mass 引力微子一種假想粒子,被假定為引力相互作用的量子,并被推測為具有無限長壽命、零電荷和零靜止質量

We could imagine that the force was balanced by an electromagnetic force generated by the electric charges in the other stars through an electromagnetic field around the stars 我們可否想象成,這是由于附近其他星體所帶電荷,在兩星周圍產生的電磁場在起作用,抵消了這個力。

Langevin is noted for his work on paramagnetism and diamagnetism , and devised the modern interpretation of this phenomenon in terms of electric charges of electrons within atoms 朗之萬以他的順磁性及反磁性的研究而聞名,他想出了用現代的原子中的電子電荷去解釋這些現象。

To generate electric charges . if you tilt the disk and slowly run your hands over it , the statically charged balls will organize themselves into branching patterns 如果你將圓盤傾側,并用手在上面緩緩掃過,帶有靜電的鋼珠會形成分支的圖案,就像木星及地球大氣層中的閃電。

Between these two tiny particles , the proton and the electron , there is a powerful attraction that is always present between negative and positive electric charges 在質子和電子這兩個微粒之間有一個很大的吸引力,而這個吸引力總是存在于正、負電荷之間。

When a big rain - cloud becomes electrically charged , and the electric charge lumps between the cloud and the ground , there is a flash which we call lightning 一大塊積雨云載電時,電荷在云層和地面之間掠過,就會產生我們稱之為閃電的閃光。

The effect on cellular pressure , which was given by the electric field force produced by electric charge on the plant cell membrane , was analysed through this formula 利用該公式分析了植物細胞膜上電荷產生的電場力對細胞內壓力的影響。

When placed on a special turnrable they vibrated or hummed in an unusual rhythm as thought an electric charge was passing through them 當放置在特別的轉盤之上時候,它們振動或依一個不尋常的旋律嗡嗡響就像一個電荷正在通過它們。

Do not tamper with or damage grounding systems ; they are provided to prevent the accumulation of static electric charges which could act as a source of ignition 不得損壞或破壞接地系統,它們可防止靜電積累,靜電也是點火源。

We now focus attention on electron 1 and regarded electrons 2 , 3 … n , as being smeared out to form a static distribution of electric charge 我們現在把注意力集中在電子1 ,而把電子2 , 3 … , n看成是彌散開形成一個穩定的電荷分布。

Electrostatics - part 2 - 1 : measurement methods ; ability of materials and products to dissipate static electric charge iec 61340 - 2 - 1 : 2002 ; german version en 61340 - 2 - 1 : 2002 靜電學.第2 - 1部分:材料和產品消耗靜電荷能力測量方法

Those conventional electronic devices move electric charges around , ignoring the spin that tags along for the ride on each electron 這種傳統電子元件只會移動電荷,卻忽略了電子與生俱來的自旋特性。

In other words , the two stars have positive and negative electric charges and therefore they are attracted each other electronically 也就是說,這兩顆星帶有相反的電荷,因而會產生靜電引力。
