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.

The results were as follows:The unit-roots characters (weight, length etc.) and 15N absorption decreased progressively downward. 15N absorbed by any unit roots could be transported from root to tiller and from tiller to tiller, but the transporting ratio was different.The pattern was as follows: when 15N was offered to total roots of plant or only to primary roots, it was transported to main stem and then decreassingly to tillers from lower unit to upper one, when 15N was offered to n unit-root, it was transported to n unit tillers, then to n + 2 or n-2 unit tillers , followed by n + 1 or n -1 unit tillers , and finally to other unfeed roots.

In this paper, firstly using natural fatty acids including lauric acid, myristic acid, palmitic acid etc. and disproportionated rosin as starting materials, the acyl reaction of starting materials with SOCl_2 respectively, and then using Schotten-Baumann condensation: on the reaction conditions of alkalescence, condensation of acylchloride with amino acid (sarcosine, glycine, alanine etc.), and then acidification, saltation. A series of anionic surfactants of N-acyl amino: sodium N-fatty acyl sarcosinate (SFS-12, SFS-14, SFS-16); sodiun N-fatty acyl glycinate(SFG-12, SFG-14, SFG-16); sodium N-fatty acyl alaninate(SFA-12, SFA-14, SFA-16)and sodium N-disproportionated rosinoyl aminatewere prepared. During the preparation of N-acylamino acid, the reaction conditions of acylchloride with amino acid condensation were identified by optimizing the synthetic conditions of N-lauroyl sarcosine: mol ratio of amino acid to acylchloride 2:1, reaction taken place in a solvent composed by acetone/water 2:1, acylchloride and 20% NaOH were slowly added to the reaction mixture at the same time while maintaining the pH at 9~10, after completion of adding maintaining reacting for 2.5h at 25℃.
