It shows that slime of different concentration have difference in combustibility. Combustibility of slime which concentration is about 67% is better than others. Lots of datum of combustibility can be obtained using thermal analysis technology. It can be used for improving burning methods of slime and designing boiler.

Theoretical Part: Through theoretical analysis of chemothermodynamics, combustion and engineering thermodynamics, factors that affect explosion limit were determined, which include temperature, pressure, spark ignition energy, electrode shape, direction of flame propagation and size of explosion vessel.

理论部分：根据化学热力学、燃烧学和工程热力学的基础理论，从本质上定性地分析了爆炸极限的影响因素，包括温度、压力、爆炸容器的大小、点火能量大小、以及火焰传播方向等，得出了这些影响因素对爆炸极限的影响规律，以确保实验有完整的理论基础指导；在此基础上本文提出了一种新的推算在常温常压下可燃性纯质和混合工质制冷剂爆炸极限浓度的理论方法，该方法由可燃性气体的化学组成来推算上下限浓度，不需要其它条件；对混合工质制冷剂，只要再知道混合配比，即可以推算出爆炸极限，使预测爆炸极限的工作更简单、方便。

It"s considered that the algae blooms control function in the algae"s growth dynamics model is influenced mostly by the water temperature, sun illumination, water flow speed and the concentration of the nutriment in water. A function including the four elements was built. By using cell mapping algorithm and contacting with the practical water condition of the Wujiang river and the Hanjiang river we analyzed and computed the algae blooms in the two areas and found the result was very near to the practical result. And we found that the ascend of water temperature and the descend of the water flow speed will contribute to the growth of algae and the nutriment is the substance basis of the algae blooms but not the only element. It must be under the condition of condign water temperature, enough sun illumination, slow water flow and abundant nutriment that algae blooms may break out unexpectedly.

本文认为藻类生长营养动力学模型中的水华爆发控制函数主要受水温、光照强度、水流速和营养盐浓度的影响，构建了包含水温、光照强度、水流速和营养盐浓度的水华爆发控制函数，通过对乌江、汉江的水华爆发进行胞映射分析，得到的计算结果与实际监测非常吻合，并认为水温升高和水流速下降将有利于藻类生长，营养盐是水华爆发的物质基础，但不是唯一因素，必须在适宜的水温、光照、缓慢的水流和充足的营养盐条件下，藻类才可能出现突发式的"疯长"，即水华爆发。
