Studying between Genetic Arithmetic of Digital Human Body and SARS Epidemic Disease

The authors have had an introduction, through linking with SARS epidemic disease, mainly from the basic concepts,the achieveing methods,the scheme theorem and building block hypothesis of genetic arithmetic of digital human body,and so on.Genetic arithmetic of digital human body is a kind of group type operation.The operation makes all of individuals as objects.The genetic arithmetic of digital human body includes three kinds of genetic operation,i.e.,selection,exchange and catastrophe.It provided a theoretical basis for studying of digital human body and SARS pathological changes mechanism.
