Positive analysis of floating population and illegal drug diffuseness in Yunnan;

Based on the fact of the toxic gas diffusion from gas explosion, Gaussian puff model was improved, and the formula in accord with the diffusion rule of toxic gas from gas explosion in mines was set up.

BASS model is an important method of the application of the product diffusion, and various expanding models have also provided great convenience in today s economic analysis and forecast.

Under the framework of decision theory, this paper presents a multi-stage innovation product diffusion model with the theory of dynamic analysis, which includes the effect of price and advertising.

Considering the factor of price, the paper analyses product sampling level with the theory of innovation product diffusion theory, especially discusses the problem under price strategies of market skimming and market penetration.

This thesis has done some researches on how the companies can make the production diffusion successfully by guiding and controlling the behaviors of the market agents.
