本课题研究用天然紫荆花色素对纸进行染色是可行的，染色液适宜pH值为3.5，加入少量氯化钠可明显提高染色纸的色彩热稳定性，纸渗水的不褪色性好，染色效果好；天然紫荆花色素代替或部分代替合成色素生产儿童用品和食品包装用彩色纸可明显减少合成色素对人体造成的危害，符合环境对包装材料的要求。

In the paper, an optimal method for node labels in the finite element is presented, which is an inductive and deductive method. By the analysis to the order features of the nodes when the network bandwidth is the minimum value, we can induce three regulars. Testing a large number of examples, which show that the presented scheme can reduce bandwidth for arbitrary mesh by renumbering the nodes, proves the correctness and reliability of the regulars. Thus the memory of computer is saved and the compute efficiency is improved.
