Possession of trawl net , spear gun , explosives , chemicals or devices using electric charge which may be used for fishing 持有拖网、鱼枪、炸药或可用作捕鱼的化学剂或电殛装置
In other words , the two stars have positive and negative electric charges and therefore they are attracted each other electronically 也就是说，这两颗星带有相反的电荷，因而会产生静电引力。
Those conventional electronic devices move electric charges around , ignoring the spin that tags along for the ride on each electron 这种传统电子元件只会移动电荷，却忽略了电子与生俱来的自旋特性。
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 静电学.第2 - 1部分:材料和产品消耗静电荷能力测量方法
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 我们现在把注意力集中在电子1 ，而把电子2 ， 3 … ， n看成是弥散开形成一个稳定的电荷分布。
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 不得损坏或破坏接地系统，它们可防止静电积累，静电也是点火源。
When placed on a special turnrable they vibrated or hummed in an unusual rhythm as thought an electric charge was passing through them 当放置在特别的转盘之上时候，它们振动或依一个不寻常的旋律嗡嗡响就像一个电荷正在通过它们。
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 利用该公式分析了植物细胞膜上电荷产生的电场力对细胞内压力的影响。
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 一大块积雨云载电时，电荷在云层和地面之间掠过，就会产生我们称之为闪电的闪光。
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 在质子和电子这两个微粒之间有一个很大的吸引力，而这个吸引力总是存在于正、负电荷之间。
