摘　　要：以测定硼泥及三种含碳酸盐类天然物质分解动力学参数实验数据为依据,推算了这四种物质在不同温度下达到不同分解度所需时间;讨论了在本实验条件下和实际条件下分解过程的限速环节。这四种物质在高温下均有较大的分解速率,在相同温度下,硼泥的分解速率最大。In this paper, on the base of experimental data of decomposition kinetics of borc-sludge and other three natural carbonate containing materials, the times needed in arriving defferent deccmpcsition ratios at defferent temperatures are deduced and calculated. Besides, the rate control steps in the processes of decomposition are discussed in the conditions of beth this experiment and reali ty. The results show that these four materials as a whole, have higher decomposition rates at high temperature, and bore-sludge has the highest at the same temperature.
