    • A crystallization method includes: actually measuring a particle number of the crystals precipitated from the saturated solution and a concentration of the saturated solution, while cooling the solution according to a cooling temperature profile; calculating an absolute particle number of crystals precipitated from the saturated solution according to a mass balance, based on an actual measurement value of the particle number and an actual measurement value of the concentration; heating the saturated solution when the absolute particle number exceeds a threshold to perform heating control so that the absolute particle number becomes a set value; and cooling the saturated solution again according to a preset cooling temperature profile after controlling to dissolve excessive crystals in the solution so that the absolute particle number returns to the set value.
    • 结晶方法包括:根据冷却温度曲线实际测量从饱和溶液中沉淀的晶体的颗粒数和饱和溶液的浓度,同时冷却溶液; 基于粒子数的实际测定值和浓度的实测值,计算从饱和溶液中析出的结晶的质量平衡的绝对粒子数; 当绝对粒子数超过阈值时加热饱和溶液进行加热控制,使绝对粒子数变为设定值; 并在控制溶解溶液中的过量晶体之后,根据预设的冷却温度曲线再次冷却饱和溶液,使得绝对粒子数返回到设定值。
