This paper analyses the biological effect of electromagnetic radiation to the cardiovascular system, introduces and carries on the comparison to the three different kinds of electrical models of the cardiovascular system, and changes the artery model based on one model in them, thus fixs on the new electrical models of the cardiovascular system--the circulation of left heart and artery.

06% product purity after simulating the PSA oxygen-making flow using electrical network model and optimizing operation parameters,using carbon molecular sieve to absorb most of the Ar and N_2 from air,then desorbing around 70% oxygen as the feed-in gas of 5A zeolite unit and taking out remained N_2 from it.

Using the electrical network model,the valve parameters are optimized in the process of making pure oxygen by pressure swing adsorption.

There are generally three major categories in smoke control models, which are zone model, field model and net model.

By applying Kohonen net model,new conception of weighted value is introduced,weighted values are determined based on entropy and statistical theory,weighted and normalized Minkowsky distance is computed,minimum distance is veried,and similar clustering centers are merged according to hypothesis testing theory.
