Based on the surveu of commercial frame structures after fire especially after a long time conflagration, the damage that arise and the characteristics of the structural members are discussed in this paper. And the reasons that caused the damage are also analyzed.
This paper analyzes causes of 7·29 conflagration subjectively and objectively and raises tactics to put out the fire of this kind based on lessons from 7·29 conflagration.
Two governing factors for integral firmness of building structures, that is the structure safety and structure durability, were analyzed from the accident of building collapse caused by Hengyang big fire.
The research shows that the excellent cooking effect of thick crucian carp soup can be achieved when the proportion of fish to water is 1:4, the appropriate length of time of laying up is six hours and the temperature should be controlled within the range from medium to big fire.
《Design Technical Regulation of Thermal Power Plant》(DL5000-2000)the scope of application is "turbine generator unit capacity 125MW~600MW condensing power station 600MW class upwards act accordingly".
The debate surrounding peacekeeping missions and humanitarian intervention has become particularly poignant with the conflagration of violent conflict and incidents of genocide, presenting States with a moral and legal dilemma.
Transmission personnel desired to know whether the line had failed and resulted in the structure fire or whether the structure had caught fire and the subsequent conflagration resulted in the failure of the transmission line.
By the end of the year 1956, 84 commercial samples of different botanic origin named "Pai-Tou-Weng" (白头翁) were collected from 18 provinces and municipal districts in China, among which 16 species in the following table are identified. № Scientific Name Family Sourcos 1.

Based on the last 500-year data of volcanic eruptions, the statistical relation between large volcanic eruptions and the surface air temperature and precipitation in China is investigated. It is found that the effects of volcanic eruption on temperature are more significant than on precipitation. Two lowerings of temperature in China after a large volcanic eruption respectively occur on the eighth month and the eighteenth month. Moreover, the second temperature-decrease is more severe than the first. It is ...
This paper inquires into the experiment of Copperoxide reducted with carbon.The Spirit Lamp with big fire is used for heating.But it will bemore important for the charcoal to be elected strictly,grin- ded,stored,blended in accurate rate and put into a thin-tube.This experiment shows clearly that it is done in shorter time for classroom demonstration,with clearer exothermic appearance,bigger grains of copper,better re-appearant properties.It is well suited to the demon- stration in teaching.
