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.

The analysis indicates that the vertical motion in the WPSH area is mainly caused by the latent heat release of mons.

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.

By means of HRR 3 heat release rate system of American ATLAS Electric Devices Company and according to Airworthiness Approval Tag of Federal Aviation Administration FAA.

A set of experiment system is used for measuring heat release rate of fire in ISO 9705 standard room.

Analyzes the method and principle of fire detection,discusses the atrium fire detection technology and the establishment of the computer supervision system,The supervision system is mainly usde to test the two important parameters in the fire:heat release rate and temperature.
