Relationship between reference point potential and potential distribution of normal electrocardial field on the thoracic surface of healthy individuals;

Electromagnetic tomography of two-phase flow is forward simulated by finite element method(FEM) to model potential distribution in different flow types and measuring combinations,meantime,influences of amount and size of electrodes to the potential distribution are sought simply,then 6 kinds of typical sensitive fields are simulated.

The factors effecton the potential distribution in the electrode are described theo- retically.

The characteristics of foamed metal electrodes are investigated to study electric potential distribution in electrolytes on foamed metal cathodes and the mathematical models are proposed.

The electric field of a linear charggd and a grounding right angle conductor is calculated by using the conformal mapping on the coordinate system of the complex number,and its electric potential distribution and electric field intensity distribution are obtained.

This paper analyses the electric potential and field intensity around the conducting spheroid in even electric field,and deduces the distribution low of induction electric charge on field intensity and surface of conducting spheroid.

The potential profile on the diametral line on uniformly charged petal-like plane is deduced by means of potential formula of point charges.
