As long as the root of the characteristic equation is within the unit circle of z-plane and the corresponding PID parameter is got, the closed loop control system is sure to be stable. Although the root of the characteristic equation can vary within the unit circle of z-plane,different value may affect the control property differently.

本文所采用的这种确定PID参数的方法，虽然可以使特征方程的根在z平面的单位圆内任意取值，但各种取值情况对变风量空调系统的控制品质的影响却不同，因此，要对各种特征方程的根的取值情况进行寻优，本文采用遗传算法对特征方程的根进行寻优，从而使控制器的参数得以优化。

The results were as follows, the total cultivated area of Liaoning province has declining tendency in recent 26 years, the total grain yield and the grain yield per unit area increased in "wave" style; the grain yield per unit area and total planting area had the great effect on total grain yield, and the effect of yield per unit area on total grain yield is bigger than that of planting areas; the yield and the planting area of different crops also affected total grain yield greatly, and maize, rice, durra, wheat affect the total grain yield by grain yield per unit area, while millet, maize, wheat affect the total grain yield through planting area changing.

得出如下结论，辽宁省近26年粮食总播种面积呈下降趋势，粮食总产量和平均单产受气候条件影响呈波动式增加；粮食总播种面积和平均单产均显著影响着粮食总产量的变化，并且粮食平均单产的变化对总产的影响要大于粮食播种面积的影响；各种作物的产量和播种面积变化都影响粮食总产量的变化，但各种作物对粮食总产量影响的方式不同，其中玉米、水稻、高粱和小麦主要是通过单产的变化影响粮食总产量，谷子、玉米和小麦则是通过播种面积的改变来影响粮食总产量的变化。

The concept of G unit interval and the definition of separable degree between elements on G unit interval are given, and some properties are discussed. Based on this concept, it determined a metric p, and ([0, 1], p) becomes a metric space (It is called G unit logical metric space). In this paper, the properties and structure of G unit logical metric space are discussed in detail, and get some good results.

给出了G单位区间[0， 1]的定义并在其上引入了元素间的可分度的概念，讨论了其基本性质，并在此定义的基础上确定了一个度量P，从而([0， 1]， p)成为一个度量空间（文中称"G单位逻辑度量空间"），并对G单位逻辑度量空间的性质及其结构进行了详尽的讨论，并得到一些好的结果。
