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℃.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
