摘　　要：用LKB2277生物活性检测系统，测定了水稻线粒体代谢的产热曲线，研究了水稻线粒体体外代谢的热力学和动力学，建立了线粒体代谢活性增长期的热动力学方程，得到了一些热力学和动力学参数．The metabolic thermogenesis curves of the metabolism of the mitochondria isolated from rice have been determined by using an LKB2277 Bioactivity Monitor. The thermodynamics and kinetics of the rice mitochondrial metabolism out of the cell have been studied. The metabolic thermogenesis curves of the rice mitochondria appeared four different phases. If the rice mitochondria have been laid up for different time, the metabolic thermogenesis curves and the kinetic behaviours of the rice mitochondria are different. Some thermodynamic values and kinetic paramters, as well as some new experimental thermokinetic equations in the activity increasing phase of the rice mitochondria,have been calculated and established.
