Accumulation,release potential and spatial variation of heavy metals in urban soils of Hangzhou City.;

In this study, we measured chemical forms, adsorption capacity and release potential of phosphorus in wetlands in the urban and edge areas of Hangzhou city, southeast China.

In this study forty-nine soil samples from different residential areas in Hangzhou city, Zhejiang province were collected for analyzing forms and saturation degree of P, and investigating the accumulation and release potential of P in the soils.

The results show that the tropopause and isothermal surfaces were raised by latent heat release in the upper level,and the disturbance trough was formed at the upper level:due to the adiabetic cooling of the ascending flow.

Latent heat release and horizontal temperature advection were main forcing terms at the early developing stage, and latent heat release was mostly responsible for the almost explosive development of the cyclone, while horizontal absolute vorticity advection became the primary forcing term at the late developing stage.

Study on residual stress release in numeral control manufacture of aluminum-alloy pre-stretching board;

Evaluation for existing truss-cable composite continuous steel bridge based on stress release method;

Static loading-unloading test of sand and stress release model

The event is ore earthquake of rock burst type related to coal mine exploitation and mining activity,the micro-earthquake swarms belong to occasional local stress releasing.
