学生的综合素质受多种因素影响,如何建立科学的评估体系是各大学多年来一直探索的问题。经 过分析各种因素建立了高校学生综合素质 模型,并对高校学生的综合素质进行科学地定性与定量分析,通 AHP 过模型计算表明:综合指数得出的结果能对学生的优点和弱点作出客观评价,有利于学生的全面发展,对当前进 行素质教育具有现实意义。-The overall quality of students affected by many factors, how to establish a scientific evaluation system of universities is to explore the issue has been. After analysis of various factors to establish a comprehensive quality model for college students and college students to carry out the comprehensive quality of qualitative and quantitative scientific analysis, Qualcomm AHP model calculations have shown that: composite index can be the result of the strengths and weaknesses of students to make objective evaluation, is conducive to the holistic development of students, carried out on the current quality of education has a practical significance.

简单的讲，所谓拟合是指已知某函数的若干离散函数值{f1,f2,…,fn}，通过调整该函数中若干待定系数f(λ1, λ2,…,λ3), 使得该函数与已知点集的差别(最小二乘意义)最小。如果待定函数是线性，就叫线性拟合或者线性回归(主要在统计中)，否则叫作非线性拟合或者非线性回归。表达式也可以是分段函数，这种情况下叫作样条拟合。-Simply speaking, the so-called fitting refers to a function known to a number of discrete function values (f1, f2, ..., fn), by adjusting the number of undetermined coefficient function f (λ1, λ2, ..., λ3), makes the function and known points of difference (least squares significance) the smallest. To be determined if the function is linear, is called linear regression or linear regression (mainly in the statistics), otherwise known as non-linear fitting, or nonlinear regression. Expressions can also be a sub-function, this case is called spline fitting.

对数据结构（李春葆版本）比较详细的讲解，里面还有ppt对理论比较详细的讲解，对于像对数据结构深入了解的人大有裨益。
