On the basis of the conclusion above, the nonlinear weak controllable vectors can be obtained, which compose the second class of weak controllable matrix, by means of matrix transfermations of the first class of weak controllable matrix. Furthmore the second criterion of weak controllability, accessibility and strong accessibility, which is more standard, more succinct and more practical, is obtained. On the basis of the first criterion and the second criterion, several important problems about nonlinear controllability are discussed, which include 1 local controllability; 2 three classes of local controllable decomposition, separately by means of local coordinate changes in the neighborhood of a nonsingular point, a point on a singular surface or a designated point x〓 with a designated input u〓; 3 the character of controllability of the ith state variable x〓 in different controllable areas and their boundaries.

Based on the shortest path matrix of 20 cities, we have quantitatively evaluated the highway network development level of the region by the accessibility index, extension index, conglomeration index, and etc. The result shows that in the space structure the highway network development level is a "core-margin" model. The cities with higher accessibility indexes gather around Zhengzhou City, while those with lower ones distribute in the margin. The order among conglomeration index is accordant to that of accessibility index.

以通达指数、伸展指数、趋中指数等为衡量指标，以20个入网城市的最短路径矩阵为基础，对中原城市群区域高速公路网络的发育程度进行定量评价，结果显示：中原城市群高速公路网络在空间格局上呈现明显的"核心－外围"模式，通达指数最高的城市集中在中心城市郑州周围，较低的城市分布在外围地区，且趋中指数排序与通达指数排序相吻合。

Taking the active network as a research task, the input accessibility, the Coates graph of matrix and graph transmission etc are used to analyze the relation between reducibility of the coefficient matrix of the state equation and the electric separability of the network or the electric accessibility of the network for the first time, acquiring sufficient and necessary conditions that coefficient matrix of the state equation is reducible. Network Graph Theory, Matrix Theory and System Theory over F etc are used to derive the structural controllability criterion of the passive network over F for the first time. Then according to these theoretic results, the structural controllability problems of the active network over F are studied, acquiring several structural controllability conclusions of the active network.

The case of a bus route in Qinghuangdao was studied. The analysis results show that the efficient way to improve bus accessibility is to keep bus headway not more than 5 min, so that the optimum bus-stop spacing is below 600 m no matter how much the bus passenger demand is. But on condition of higher bus headways, optimum bus-stop spacing should be in the range of 900 to 1400 m and the bus accessibility would drop more remarkably compared with lower bus headways.
