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。

First, mathematical foundation of synchronization, i.e. the theory of parameter estimation is introduced. Then, DA/DD or NDA timing synchronization methods based on the ML estimation of timing parameter are presented. They are all widely applied in actual digital communication systems. Interpolation theory in digital signal processing has application in timing synchronization, which makes the sampling clock independent of the timing control so that timing adjustment is realized completely through digital disposal. The issue of interpolation in timing synchronization is discussed.

首先，介绍了定时同步实现的数学基础，即信号参数估计理论；从定时参数的最大似然估计出发，介绍了基于数据辅助的定时同步方法和基于非数据辅助的定时同步方法，他们在实际的数字通信系统中均有广泛应用；论文探讨了数字信号处理中插值理论在定时同步中的应用，它使得接收端的采样时钟独立于定时控制，定时调整完全通过数字处理方法得以实现。

For example,speaking 555 timer flakes and intergrated operate amplifier CA3140 to control,it is a normal thing that the timer is coming out,But today this timer adopt 555 timer oscillatory circuit as at time base signal pulse input,choise magnificated intergrated flake CA3140 to manger ,make the timing of 555 steady state time lagmay be increase one hundred multiple.

由于集成块集成度高，功能强，功耗低，速度快，价格便宜，实用灵活，开发周期短等优点，从上个世纪开始，随着各种各样的集成芯片的问世，比如说555定时器芯片和CA3140集成运算放大器芯片，定时器的形成已经是很普通的事情，但今天这个定时器采用555定时器振荡电路作为时基信号脉冲输入，选择可放大的集成运算放大器3140控制器，使555的稳态延时范围可以增加100倍。

One of the wine regions to have developed this century is just eight degrees south of the equator, in northern Brazil, in what is, basically, tropical desert where vines would be expected to stand no chance but, thanks to cunningly timed irrigation from the nearby S?o Francisco river, are tricked into two full growing seasons a year, thereby halving production costs per bottle.

本世纪已经开发出的葡萄酒产区之一就位于南纬8度巴西北部，在这片基本上属于热带的沙漠里，人们想不到葡萄在那里有生存的希望，但来自附近圣弗朗西斯科河定时的灌溉，使得这里每年有两个完整的葡萄生长季节，这令每瓶葡萄酒的成本降低了一半。
