Applying ai and gis the paper studied systemically landslide hazard zonation on the base of gis . the paper involves several innovations as follows : 1 . on the base of former study work the paper research systemically factor system and the method to number these index and math model of landslide hazard zonation 第11页西南交通大学博士研究生学位论文本论文的创新之处在于: ( 1 )在前人研究工作的基础上,更系统的从滑坡危险度区划的因素体系及其量化、数学建模等方面做出了较全面的研究; m将模糊集理论的综合评判方法全面的引入滑坡危险度区划理论中。
The equation for the quasi - continuous atom laser beam wave - function is given by schrodinger equation , the beam width , divergence curvature radius and quality factor were introduced to represent the atom laser beam whose transverse potential could be separated . for the conservative quality factor system in some direction , we can ge t the propagator of abcd formulation 本文在含时量子系统传播子的abcd形式理论的基础上,引入某一方向的束宽、发散角、曲率半径和品质因子等光束传输参数来表征横向势能满足x和y分量相互独立的原子激光的传输。
As to the part of the affection of the intangible factor upon the regional economy , this thesis takes an original research over three aspects , that is , the intangible factor ’ s effect on the factor system of economic growth , on the regional economic growth modes change and on the economic growth efficiency accounting , and achieves a conclusion that the intangible factor has a wide and everlasting affection upon the regional economic growth 在“无形要素对于区域经济增长的影响”部分,论文从无形要素影响经济增长的要素体系、影响区域经济增长方式变更和影响经济增长绩效核算三个方面进行了独立的研究,认为无形要素对于区域经济增长的影响是深刻而全面的。
In mathematics, a factor system is a function on a group giving the data required to construct an algebra. A factor system constitutes a realisation of the cocycles in the second cohomology group in group cohomology.
