The paper describes the typical analogic analysis engineering and the BMP boundary element program based on this engineering, which provides a necessary technical condition for solving this bottleneck by combining.

In order to avoid the real estate market in developing countries like China from getting over flourished,this paper raises the procedure and the principle of the analogy analysis method that is used in the stage of the real estate operating.

The function and characteristics of analogy analysis in sci-tech editing are discussed in this paper.

Based on the analysis of the traditional inheritance mechanism, a new inheritance mechanism——soft inheritance is proposed, which enhances the traditional inheritance by providing analogy definition, analogy analysis and analogy derivation in object oriented programming.

This paper cites some analogous analysis methods used in recent and representative regional environmental assessment and programme.

The method of analogous analysis, which gives emphasis on physicalmeaning, is introduced.

Its feature is making use of the analogous analysis of single switch isolated type of basic PWM DC/DC converters.

Based on the theory of the electromechanical analogy and the special wave equation,the equivalent circuit of the exponential acoustic waveguide was derived,the formula of its impedance transformation was obtained.

By means of electromechanical analogy, the eigenfrequency equations and the formulas of corresponding eigenfrequency for a uniform massive spring system with several common boundary conditions are derived.
