    In this paper some heat flow values the geothermal in the Bohai sea and adjacent region are described.The temperature distribution, geothermal gradient and heat flow in this region have a tendency of increasing gradually from the land to the sea. This tendency is well correlated to the geotectonic features and the structure of the crust and upper mantle, and approximately coincident to the features of other geophysical field in this region. It is suggested that the possible upwelling of the material from the upper mantle in this region, especially in some segments of Tangchen-Lujiang fault belt, caused the deep parts of the crust different in temperature and density, leading to high concentration of thermal stress.

    An improved linearized theoretical model has been developed for studing effects of cold plasma layer on instabilities. MHD perturbation equations with arbitrary conductivity at plasma edge are derived. As a result the effects of temperature and density on the growth rate are obtained, which reflect the main characteristics of the present Tokamak experiments. In the present work the cold-plasma edge plays a fundamental role, being directly responsible for the rapid growth of tearing modes through the introduction of a destabilizing effect. The surface kink instabilities of the modes 3/1, 2/1 and 3/2 are excited gradually one by one due to the increased cooling of the outer plasma region. Their growth rates can develop from the growth rates of tearing modes to these of free boundary kink modes, in accordance with the temperature and density of plasma at the boundary. As the temperature at the outer edge increases, the stable "window" will become wider and wider.Decreasing relative density ne of the outer region will lead to a deteriorated situa-tion for confinement. As ne ≤ 10-3 there no longer exists a stable "window".In view of above reasons the present work does provide a possible physical explanation of the major disruption. When the m = 2 island makes contact either with the limiter or an outer region of cold plasma, a disruption is initiated.
