Firstly, the connection matrices are strongly connected Boolean matrix, it is shown that the maximum length of limit cycles for FBAM is the period index of the product of the connection matrices. Thus, the maximum limit cycle is reachable. Secondly, two strongly connected components are connected by walks, it is proved that the maximum length of limit cycles for FBAM is the max. of the period index of the two strongly connected components if they are prime, otherwise, it is the least common multiple of the two period index. Finally, n strongly connected component are connected in succession, the method for computing the maximum length is described. By different patterns are presented to the networks, diminishing the number of the strongly connected components until only two components.

第一，连接权矩阵为强连通布尔矩阵，此时模糊双向联想记忆网络的最大极限环长度为连接权矩阵乘积的周期指数，从而极限环具有可达性；第二，两个强连通分支有路径连接，此时如果两个强连通分支的周期指数互素，那么网络的最大极限环长度为其最大者，否则，网络的最大极限环长度就等于二者的最小公倍数；第三，n个相邻强连通分支有路径连接，给出了计算最大极限环长度的方法，通过激发模式的变化，逐渐减少强连通分支的个数，直到只有两个分支。

Purification and analysis of AT-toxin Firstly, we detected the components of protein and nonprotein, the results showed that AT-toxin is a nonprotein. We have carried out the liquid chromatogram analysis of the toxin. The result indicates that there are many components in this toxin and there are four kinds of components which content is more than others. At last, we have the experiment of separating the cpmpositions with the silica gel and we get four components which are active.

AT-毒素的初步纯化与分析为确定AT-毒素的组分，首先对毒素的蛋白质和非蛋白质组分的毒性进行了测定，结果表明：AT-毒素活性组分为非蛋白质；对毒素进行硅胶G薄层层析，初步分离得到10种组分，其中四种组分具有活性：组分Ⅵ、Ⅶ、Ⅷ、Ⅸ，初步说明了该毒素含有多种组分；进一步对该毒素进行液相色谱分析，也发现该毒素含多种组分，其中四种组分峰高和峰面积较大，含量较高；其致毒活性可能是由这些组分协同作用的结果，它们之间可能存在正协同或负协同作用关系。

System speaking of the Master CAM, first must establish the components the geometry model, according to the components actual size, draws its processing part the contour line, does not need to draw the entire components the model, guaranteed the computation production the cutting tool way coordinates accuracy, and may use the Master CAM Chinese Library level the function, when determination cutting tool way, transfers or the hideaway, the selective treatment needs contour line; Next, the formulation processing craft and the definite craft parameter, chooses the cutting tool, the processing semi finished materials, the work piece origin of coordinates again and so on, establishes the work piece coordinates system, definite work piece coordinate system and engine bed coordinate system relative size, thus obtains the components processing correct cutting tool way; Finally, the simulation function which system provides using the Master CAM, the realization simulation processing.

对于Master CAM系统而言，首先要建立零件的几何模型，根据零件的实际尺寸，画出其加工部分的轮廓线，无需画出整个零件的模型，以保证计算生成的刀具路径坐标的正确性，并可利用Master CAM中图层的功能，在确定刀具路径时，加以调用或隐藏，来选择加工需要的轮廓线；其次，制定加工工艺并确定工艺参数，再选择刀具、加工毛坯、工件坐标原点等，建立工件坐标系统，确定工件坐标系与机床坐标系的相对尺寸，从而得到零件加工的正确刀具路径；最后，利用Master CAM系统提供的仿真功能，实现模拟加工。
