On the NiO/SiO〓 catalyst prepared by IM, the main hydrogenation product of MA was SA, the activity and selectivity were almost no relation with the nickel content and nickel species 3. Summarizing the characterization and activity evaluation of the catalysts, we concluded: On nickel based catalyst, when NiO was crystallite, and the Ni〓 that was prepared by reducing, hydrogenation of the MA could lead to SA but not to γ-BL; when NiO was cluster and had a properly interaction with the support, the Ni〓 prepared by reducing, could hydrogenate MA to SA then to γ-BL. When NiO cluster and crystallite were both existed on the catalyst, the hydrogenation products were mixture of SA and γ-BL, and the amounts of SA and γ-BL were related with the ratio of cluster and crystallite.

综合催化剂的表征和活性评价得出：当镍基催化剂上氧化镍以结晶态存在，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到丁二酸酐，丁二酸酐难以进一步加氢为γ-丁内酯；当镍基催化剂上氧化镍以簇团形式存在，与载体之间有适当的相互作用时，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到的丁二酸酐进一步加氢为γ-丁内酯；若催化剂上氧化镍既有结晶态又有簇团形式时，随二者含量比例不同而得到丁二酸酐和γ-丁内酯的混合物。

Along with the shap of the cluster,the way in which it is owned is critical.If the pattern of ownership is not in accord with the physical properties of the cluster,the pattern will not take hold.Very simply,the cluster must be owned and maintained by its constituent households.The households must be able to organize themselves as a corporation,capable of owning all the common land they share.

随形的集群，以何种方式，它是国有，是critical.if格局的所有权是不符合物理性质的集群，这种趋势不会采取hold.very简单地说，集群必须国有并维持其组成households.the户必须能够组织起来，作为一间公司，能够拥有所有的公用地，他们的份额。

In this paper, firstly, it used word for the demonstration of the qualitative relationship between logistics and industrial cluster, any more, the paper analyzed the role that modern logistics in industrial clusters interior, exterior and in the cluster chain by figure,. It also reasoned the quantitative relations between them by grey correlation theory combined with amount of time series. So it could systematically demonstrate the relation between industrial cluster and modern logistics, and found out the point of penetration.
