Using homogeneous projective coordinate,this paper presents a researches of the dual of projective space and reveals the essence of dual fundamentals of projective space the same coordinate represents both point and plane,and there is a dual relation in the point and plane.

射影空间是对偶结构，用齐次射影坐标研究了射影空间的对偶原理，从而揭示出射影空间里互相对偶的点与平面的坐标之间的内在联系

For the infective subsystem, we obtain the existent condition of the subsystem equilibrium point and the uniqueness of the positive equilibrium point by the no infectious subsystem's conclusion and the image analysis. The partial stability of the subsystem equilibrium points is discussed by analyzing eigenvalue. The condition that the system has no limit cycle is obtained by the Dulac function.

对染病子系统，利用无病子系统所得结论及图像分析法，得到了系统平衡点的存在条件，正平衡点的存在唯一性；利用特征根方法判断了系统平衡点的局部稳定性；利用Dulac函数得到了系统不存在极限环的条件；利用极限方程理论得到了系统疾病消除平衡点和地方病平衡点的全局稳定性。

When the value of critical threshold larger than 1, the disease and insect pests equilibrium point is locally asymptotically stable An appropriate Dulac function should be choosed and Bendixson-Dulac creterion is used to prove that the limit cycle in this model does not exist. It explains that the disease and insect pests equilibrium point is globally asymptotically stable.

选取适当的Dulac函数，利用Bendixson-Dulac判别法证明了极限环的不存在性，说明局部渐近稳定的病虫害平衡点也全局渐近稳定。

In addition, spot color screen angle in software will normally be preset to 45 ° c (45-degree, is considered the most comfortable utilizinghuman-aware, so that the angle of the dot is arranged in horizontal and vertical lines to equal rotation, you can reduce the human ability to mesh point detection), if a Duotone image or data file into the existing business card printing and membership card making four color black%(General in the four-colour screen business card printing and membership card-making Black mesh point-and-drop, in a 45-degree is 0 degrees for yellow, magenta to 15 degrees, 75 degrees), and spot color, or with more than two spot colors, the color screen is to a 45-degree output, so use the spot color, while if it is possible with other screening to overprint colors, you must open the output color separation software color settings or the print dialog box, on the halftone angles to make modifications.

另外，专色的增网角量在软件洋凡是城市预撤为45量（45量均被觉得是人眼感知最安适的角量，让网不背摆列在与程量和垂直线不败不等角量的标的目的上可以裁减人眼差网不背的发现本领），若是一个单色调影像或是数据文件洋既有制卡和会员卡制息四色暗不败外（凡是在四色增网制卡和会员卡制息洋，不兵暗网不背不收在45量，黄为0量、品赤为15 量、青为75量），又有专色，或者是有两个以上专色，则在分色增网时城市以45量输入，所以在差专色搁置浅网时，如果有不定与其他增网颜色有叠印，则务必在分色输入时开放软件颜色撤定或打印撤定的差话框，差专色增网角量举动编削。
