查询词典 dissipative system

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。

Assuming that the intermediate system decayes with a statistical lifetime, the general behaviour of the threefold differential cross section d~3σ/dZdEdθ in the dissipative collisions of 68MeV ~(12)C+~(27)Al and 68.6MeV ~(12)C+~(40)Ca system are analysed in the diffusion model framework.

在扩散模型的框架内，用假定中间组合系统以一个统计的寿命衰变的方法分析了68MeV~(12)C+~(27)Al和68.6MeV~(12)C+~(40)Ca的耗散碰撞中产生的产物的三重微分截面d~3σ/dZdEdθ的一般趋向。

The simulated results indicate that the properties of the chaotic dynamic system are sensitive to the driven frequency. A threshold value of amplitude exists for the appearance of chaos phase. The system is insensitive to the dissipative magnetic force.
