Meanwhile,the hair-style play a important role in Chinese folk s daily life,such as:the original religious function,the taste function,the indication function.

The creactive design of mechanism in the process of mechanical scheme based on function principle;

Analysis of the function principle in the creactive design of product by the cigarette automatic machine's design and the evaluation of the cigarette automatic machine's creative design scheme,help to get a good principle scheme.

Utilizing the designing method of systematic functional principle and creation theory,the design of principle scheme has been carried out for the mechanical system of production line of thin piece punching from coiled materials.

This paper has better given some explains of mechanism of swing swaying more and more higher in the air by functional principle.

The functional principle and key technology of each part was described in detail.

Based on ameliorative experiment about swelling energy measurement of Nanning expansive soils,new technique of making soil samples and principle of work-energy,experimental investigation and theoretical derivation are done from the perspective of the energy.

In this paper we derived mass-energy relation by comparing the two methods:theorem of kinetic energy and the principle of work-energy,then indicated the error in mass-energy relation derived from the theorem of kinetic energy in relativity.
