true electric charge

It is agreed that the interaction energy of a charge system involving image charges equals those of a real charge syste

:赞同与象电荷有关的系统的相互作用能和真实电荷系统的相互作用能之间的关系应是等值关系的观

It is pointed out that the interaction energy and interaction force of a charge system involving image charges equals those of a real charge system respectively and the self energy and total energy of a charge system involving image charges not equals those of a real charge system.

指出与象电荷有关的系统的互能、互作用力和真实电荷系统的互能、互作用力分别相等，自能、总能一般分别不

This paper fully analysed the noise sources,mainly discussed two extra sources – Spurious Charge and Excess Noise Factor,and calculated the SNR of EMCCD.

详细分析了其噪声来源,重点讨论EMCCD相比普通科学级CCD特有的乱真电荷和噪声因子,计算信噪比。

The vacuum load,the structure of the guide tubes and the pumping system for 30_barrels pellet injector were introduced.

最后介绍了根据推进剂用量确定的真空负荷、导管结构和抽气机
