Based on the practice of Ship′s Physical Field course innovation in recent years and the analysis of the relation between course teaching contents and naval weapon equipments,a new idea is put forward that Ship′s Physical Field course should be reoriented.

Combined with practical teaching activities,the teaching patterns of Ship′s Physical Fields course are discussed in this paper,which include the combination of teaching with scientific research and production,the combination of teaching with learning based on solving problems,and the combination of teaching with modern teaching techniques.

Property monitoring and condition-based maintenance for ship physical field;

The result of magnetic measuring experimentation is time-serial data-set,which could not been used to model warship magnetic field directly.

Magnet simulation is often used in calculating a vessel′s magnetic field,but the precision is affected by this positions of the magnet that often depend on human experience.

On the basis of analyzing the time frequency of a ship magnetic field by using short time Fourier transform, this paper discusses the time frequency distribution characteristics of the ship magnetic field.

This paper uses standardized correlation coefficients as the standards balacing the degree of simularity of multi channel signals On the basis of comparing measured data with simulated ones, it analyzes and sums up the degree of simularity of the passing characteristic curves of ship magnetic fields and hydro dynamic fields in unmerical quantities with the help of a new method .

The conclusions prove that the electric field of warship has obvious characteristics and can be detected easily.
