However,the data on the increase in TH related fatalities,adversereactions,and the drug addiction presented in recent years have been obtained frompostmarketing surveillance and case reports,unfortunately,cellular and molecularmechanisms involved in neurotoxicity,dysfunction and addiction potential afterchronic and abused TH administration are not well documented.

The stress dependence of the dynamic modulus was analyzed during the cement-soil dynamic modulus test.

It is evident that the responses of subgrade soil are non linear and hence,with a large number of experiments and theoretical studies,this paper analyses the stress dependency model of the resilient moduli and modifies the foreign widely used model in existing deficiency and theorial inaccuracy.

This paper holds that the relationship between enterprises in the technological innovation network has become increasingly important,and considers the nature of inter-firm relations is power-dependence.
