Then, a hypothesis of "double force source" for tectonism is put forward, its main points are: the tectonism is not only the result from the action of tectonic stress, but also the result from the action of "double force source", namely, the tectonic stress and subsurface fluid force including force produced by precipitation, etc.

提出了&双力源&构造变动假设，即构造变动不仅是构造应力作用的结果，而且是构造应力与地下流体力共同作用的结果；二者共同作用因方式不同而产生不同的构造变动；在构造变动孕育与产生过程中，构造应力的作用是第一位的，地下流体力则是调制性的，只有那些能与构造应力增强过程产生力学耦合的地下流体力，才能调制与诱发出构造变动异常并促进构造变动。

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.
