The text give some measures to prevent freeze bulge on road such as: replacement method, insulate temperature method and tranquilization transact measure.

The use of Magnesite Heat Insulation Technique in Grain Storage for High & Large Flat Storages;

It was fund in usage that the heat insulation function of the roofs of these flat storehouses was poor,which was a serious disadvantage for realization of low temperature grain storage.

Because of having heat insulation effects to some extent,it could lower granary temperature and decrease the rising trend of the temperalure of grain bulk surface effectively in summer.

SiO_2 aerogel flexible heat insulation film;

Polyurethane foam is a kind of hard-foamed plastic with the functions of waterproof and heat insulation produced by combination reaction between materials of group A (white agent,mainly composed of such additives as polyatomic alcohol and foaming agent) and group B (black material,main ingredient of which is isocyanate).

In this article,authors analyze comprehensive performances of traditional heat insulation materials,and introduce some aspects of a new inorganic compound silicate heat insulation material,the FHP\|Vc board,such as performance,features,constitution as enclosure structures and practical application examples.

The property of the heat insulation characteristics of the single and two complex phase change material systems depends on the number of their output power.

Taken small-sized hollow concrete block as example reasons caused the common quality defects of block masonry buildings such as wall cracking, leakage,unfavorable thermal insulation performance and earthquake resistant effect and so on are analyzed,at the same time corresponding prevention measures are proposed in order to ensure the normal service performance of block masonry buildings.

And it has more advantages compared with other insulating materials and is more applicable to the external wall and roofing thermal insulation system for buildings in areas with adverse weather conditions.

From usable function, cost, thermal insulation, sound insulation, seismic performance and other aspects the characteristics of hollow concrete beamless floor are introduced as well as its application scope and engineering principle.

This paper discusses the design of cooling and heat insulation method combined with climate feature in Nanchang,from various aspects such as planting green vegetation,putting an interlayer for ventilation and heat insulation in rooftop,mounting solar energy facility and utilizing the reflection principle of light,and so on.
