In this region , and the oversaturation of solution was going from up to down . When the relaxing speed of oversaturation increased to be equal to the growing speed , crystal process changed to the chemical reaction region controlled by Mo 8O 4 - 26 polymerization .
当过饱和消除速度增大到与生成速度相等时，过程转变为由Mo8O4-26聚合反应控制的化学反应区域，此区域L和ΔC处于稳定不变的状态。
