Be aimed at these complicated mechanism, Miao Xiyong put forward "three essential therapeutic methods for treating haematemesis": promoting blood circulations tonifying liver、 discending Qi, indicated deeply the dialectical relationship between regulating Qi circulation and dispersing fire、 promoting blood circulation an.

The Expansion Application of Three-Factor Method for First Order Circuit;

This paper puts forth the “three-factor method”for the first time to explain the forming mechanism of lift-off.

By asking the essence of the answer of the differential equand its mathematics-physics meaning,the common formula of the three-factor method has been deduced,and then the paper focuses on finding out a method for answering the steady state answer.

Researches on the application of three-element method for first order circuit;

This paper introduced Three-element method from two point of view and analysed the main point to solve transient state of the first-order circuit with Three-element method.

The applied range of three element method is extended for two cases:First,the excitation is ke-αt+U0 in the firstorder circuit,second,the excitation is direct U0 in the Secondorder circuit.

The zero state response to an arbitrary excitation in a fist order circuit can be solved by either the convolution integral or the three element method.
