该曲线的极值点就对应了从聚式流化转变为散式流化的临界转换点。
In fact, as the transition of the children with a bed, a baby bed size is very important.其实，作为孩子的过渡用床，婴儿床的尺寸非常重要。
When the second derivative of the bubble number in unit bed volume with respect to gas velocity equals zero, the flow regime transition occurs. The model fits fairly well with the experimental data.导出了当单位床层体积中气泡数目对气速的二阶导数为零时发生流型转变，该模型的计算机结果与实验数据吻合良好。
