This paper analyzed the fire data,evaluated the fire losses of 31 provinces in China by the cluster analysis and discussed the relationship between development of a province's economy,fire protection devotion and fire loss.

The establishment of fire spread model, determination of mathematic expectation and square deviation of building fire loss .

Accuracy of fire disaster has great influence on developing of the whole economy as well as the level of economic development on the fire, fire accident and fire loss increased rapidly because of great raising in social wealth.

Analysis and prediction on the time trend of fire cost in China;

A non-destructive testing and synthetic evaluation method based on evaluation of the load-carrying capacity for fire damages of concrete structures were proposed.

This paper summarized the evaluation methods, domestic and abroad, for fire damage of concrete structures.

Accirding to the principles of infrared thermal imaging and electro chemisty testing,and taking advantages of infrared thermal imaging and electro chemistry methods,the fire temperature,the strength loss and the fire damage depth of reinforced concrete members were tested and analyzed from surface toinner,then the damage grading of structures were evaluated synthetically.

Mathematical model of exergy loss based on signal flow diagram theory for thermal system of 200 MW units;

Equations of rate of exergy loss for shell and tube exchanger are derived.

It calculates the exergy loss of 2 sets of typical regenerative systems(200MW & 600MW)by the software MathCAD, based on the generalized exergy loss distribution matrix equation of regenerative systems of coal-fired power unit; then compared with the results which calculated by the traditional calculating methods.
