| 6. | This paper put forward that credit estimation and guarantee of small and middle enterprise must pay attention to its characteristics , that is to say , stressing some estimations such as " future innovation , grown - up , . development " through normative analysis remonstrating analysis , comparing analysis and research . at the same time it must deal with whole credit and part credit combination of qualitative analysis and quantitative analysis and relative relations about methods of estimation and goals of estimation . according to characteristics of credit estimation , 1 choused index and form systems of multilayer index and select combination of delphi and ahp in order to avoid subjectivity and random for setup in the course of setup of estimation index . it should adapt flexibility of anti - guarantee setup and embody its supporting function for enterprises through qualitative analysis of anti - guarantee and estimation of risk with reason . in view of mature experience and criterion of science and technology estimation , this paper introduced into concepts about index of filtration and superior and established relative and traditional methods which are suitable for modes of small and middle enterprises for credit estimation and are applied by credit guarantee
本文运用规范分析法、实证分析法、比较分析法，通过研究提出，中小企业信用评价和担保信用评估应注重中小企业的特点，即强调“未来、创新、成长、发展”方面的评价。同时还要处理好整体信用和局部信用、定性分析和定量分析相结合以及评价方法和评价目的相对应的几方面关系。在中小企业信用评价指标体系的设置中要根据中小企业信用评价的特点，合理选择指标和形成多层次指标体系，并选择delphi法(德尔菲法)和ahp (层次分析法)相结合的方法避免权重设置的主观性、随意性。 |
| 7. | Meanwhile the evaluation method of estimation matrix and fuzzy matrix had been used to confirm the weightiness of each factor with the data collected by the ordinary and expert questionnaires . so an integrated index system of executive ability of virtual enterprise was constructed
并且通过普通及专家问卷调查的形式,采用判断矩阵和模糊一致关系等综合评价方法分别确定各级影响因素之间的重要性权重,从而有创新的构建了一个比较完整的虚拟企业执行力影响因素指标体系。 |
| 8. | By these basic theories , we give an explanation for the light variation of ( 469 ) . as long as the number of the samples is increased and the methods of estimation for the rotation and shape of the asteroids are improved continuously , this kind of research will help us to understand the evolution of the asteroids , and even the evolution of the solar system
目前，对直径125究仅仅是一个开始，公里左右的小行星的形状和自转参数的观测研随着观测样本的不断扩充和反演方法的不断完善，不难想象，这一工作的研究结果会让我们更好地理解小行星的碰撞演化，甚至太阳系的演化。 |
| 9. | This model is a class of ev model . in this model , regression function that variance yt is about is nonlinear , is not measureable directly and the measurable directly is x , that is errors - in - variance . the method of estimation is more difficult than the usual because x is not measurable directly
本模型属于一类半参数的ev模型，它表明变量y _ i关于( x _ i ， t _ i )的回归函数呈偏线性的形式，且变量x _ i不能直接观测到，所能观测到的是受了误差变量u _ i干扰的变量x _ i ，由于x _ i不能直接观测到，这使得估计的困难加大。 |
