The stability of aloin decreased with the increase of temperature and heating time. However, the absorbency of aloin did not change with time under room temperature (20℃). The aloin was sensitive to light, and the aloe juice showed a yellowish green sediment in 2 hours after exposed to sunlight. The stability of aloin declined when the pH value arose. The aloe juice was more stable under lower concentration of sodium chloride and sucrose.

结果表明：加热的温度越高，时间越长，芦荟苷的热稳定性越差，而在室温下(20℃)芦荟苷的吸光度基本不随时间改变；芦荟苷具有光敏性，在太阳光照射下，2小时后便出现黄绿色沉淀物；芦荟溶液随着pH的升高，其稳定性下降；低浓度的氯化钠和蔗糖对芦荟汁液稳定性的维持比高浓度的效果明显。

According to the change of the enemy\'s quantity and the qualitative theory of the differential equation, we research the spruce aphides and its predator system. At the same time, we discussion the spruce aphid multiplication model when the natural enemy quantity is a certain value and the periodic oscillating model whose the quantity of the natural enemy changes along with the time. Obtains the stability condition of the balance point and the limit-cycle existing condition, the system presents the dissipative structure\'s character. Finally it explains that this theoretical analysis has certain practical significance regarding the preventing and controlling harmful insect.

第五章，松毛虫与其天敌的关系是食饵和捕食者的关系，根据天敌数量的变化，利用微分方程定性理论，研究松毛虫与天敌系统，讨论天敌数量为一定时的松毛虫增殖模型和天敌数量随时间变化的周期振荡模型，得到正平衡点全局稳定性和极限环的存在条件，通过计算机模拟，说明周期振荡的捕食模型能够呈现典型的时间耗散结构特征，对于防治害虫有一定的实际意义。
