试谈测绘模拟静电场的等K面分布及多用途T型数字电桥盒

AN ATTEMPT TO DRAFT THE DISTRIBUTION OF ISO SURFACE K AND MULTI-PURPOSE TYPE DIGITAL BRIDGE CASE

目前我们往往测绘模拟静电场的电位绝对值分布图，但该分布不是唯一与稳定的。若引入相对电位Ｋ的概念，则使该分布模拟静电场的特征规律──决定各＂等Ｋ面＂的几何参数与两源电极间的总电势差的绝对值大小无关．＂Ｔ型数字电桥盒＂不仅能使测绘＂等Ｋ面分布＂实现＂数字化的直接显示＂，而且它还类同箱式电桥那样可用于＂惠斯登电桥＂实验，前者优胜于后者。

At present we usually draft the scatter diagram of electric potential absoelute value for analog electrstatic field.but this distribution is neither the only one nor the stable one If the concept, relative electtic potential K,is introduced, it makes no difference between paramcters determining each iso surface and absolute value of total electric potential. T-type digital bridge case not only makes the draftig of the distribution of iso surface K reclize the directly igitixed disolay butalso it is similar to box-trpe bridge which can be used in Wheatstone bridge experiment. The former is superior to the latter.
