Following this weakly first order phase transition, the temperature dependence of enthalpy near the transition indicates that the lowest supercooling temperature of the isotropic phase T~*, the N-I phase transition temperature T _C and the highest superheating temperature of the nematic phase T~(**) are very close to each other.

By analyzing and diagnosing the process of internal high temperature overheating fault in 110 kV main transformer, expounds the chromatogram analysis method of transformer oil, through disassembling test and repair in locale, verifies the correctness of diagnosis.

The maximum temperature and supreme pressure in the accident are calculated on the hypothesis that the combustible substance is TNT and it burns in an adiabatic and .

For the terrestrial ecosystem, the daily maximum temperature is the important factor determining the normal photosynthetic mechanism control,fruit quality and glaciers melting.

Based on the daily maximum temperature of mid-summer(June to August)from 1950 to 2005,T213 grid wind data,and vertical velocity from June to August in the year of 2002 and 2003 in Wuhan,the climatic characteristics of mid-summer high temperature,high temperature processes and characteristics of the western Pacific subtropical high activities are studied.
