On the other hand, Let M~n be an z-dimensional complete noncompactoriented submanifold with finite total curvature in an-dimensional simplyconnected space form F~ of constant curvature c. In this thesis, we provethat if M satisfies one of the following: n≥3, c=0 and integral from n=M H~n＜∞;n≥5, c=-1 and H＜1-2/n~(1/2); n≥3, c=1 and H is bounded, where Hdenotes the mean curvature of M. then the dimension of the space of L~2 harmonic1-forms on M is finite.

本文还证明：若具常曲率c的完备单连通空间型F~中具有有限全曲率的n维完备非紧可定向子流形M满足下面条件之一：n≥3，c=0且integral from n=M H~n＜∞；n≥5，c=-1且H＜1-2/n~(1/2；n≥3，c=1且H有界的，则M上L~2调和1-形式空间的维数是有限的，这里H为M的平均曲率。

While, it is the II mechanism that plays the main role in the therapy, that is the producing of cytotoxin singlet oxygen affected by the oxygen.

When used in LAB complex unit with multi-step hydrogenation process,DSH-1 selective hydrogenation catalyst,which contain noble metal Pd,can transmit diolefin s to olefins effectively,and has good activation and selectivity.

DSH -1型含贵金属Pd双烯选择性加氢催化剂与多段加氢工艺结合，应用于脱氢法生产直链烷基苯的联合装置中，能有效地将脱氢过程产生的双烯烃转化成单烯烃，具有很好的反应活性和选择性，且操作弹性大，工艺过程简单。

It indicates that the N—O bonds in the singlet dimer adsorption configurations are weaker than any other structures, and this is propitious to the NO direct decomposition. 7. Unlike NO molecules interaction with copper atoms, when two NO molecules interact with the adjacent silver atoms, the non-planar structures are more stable than the planar.

同时，单重态的二聚体与相邻的金属铜和银原子作用时，由于电子从金属原子转移到二聚体上的数量最多，因此在这种吸附构型中，金属原子被离子化的倾向最大，同时使得二聚体中N—O键被削弱的程度也最大，有利于NO的直接分解； 7。
