The thermoreversibility of phenol formaldehyde resin - borate hydrogels as a function of polymer concentration, sodium tatroborate concentration and KOH concentration was investigated by the gel - melting temperatures.

Numerical simulation of heat transfer enhancement by inverting thermal storage cells during melting;

Performance analysis of CO_2 melting process during releasing through safety valves;

Establishment and Melting of Charge Ordering in La_(0.3)Ca_(0.7)Mn_(1-x)W_xO_3 System;

Based on the several year data of permafrost in the region of Fenghuoshan Mountain,this paper not only studied the transformation of upper limit of permafrost in natural ground and roadbed but also the thawing of permafrost,and analysed quantitatively the status of heat which have entered permafrost.

Construction of the Qinghai-Tibetan Highway will change the heat exchange between atmosphere and ground surface, destruct the original heat balance, resulting in a heat accumulation in highway embankment and underlying permafrost and permafrost thawing.

The raw compositions,thaw condition,emulsifier,stabilizer and additional level were studied,we confirmed the formula and professing technology of smear process cheese.

The thawing of permafrost will surely result in the instability of the railway roadbed and its settlement etc.

To echo the International Polar Year (2007~2008) that the UN set, moreover, to awaken people's awareness of economizing and energy saving when man's survival is being threatened by the melting ice from the climate warming, UNEP set this theme.
