本文的研究目的是经由消费者人口统计变量、购买影响因素、AIO生活方式变量和购后评价情况的调查统计分析，来探讨绿色食品的消费者行为，找出影响消费者选择购买绿色食品的主要相关因素和生活方式变量因子以及人口统计变量，建立主要评价变量指标并比较其自身和购后行为的差异性及影响效果，最后为绿色食品企业制定营销组合策略和品牌形象的树立提供参考依据。

Secondly, in our methods, the essential geometry of the image single axis geometry may be specified by six parameters and this may be estimated from one conic and one fundamental matrix (a total of 12 parameters) or may be minimally estimated from two conics (a total of 10 parameters).

本文证明了单轴旋转运动的不变量可以通过一个基本矩阵和一条二次曲线来确定，在这种情况下，由于基本矩阵的自由度为7，二次曲线的自由度为5，所需确定的参量个数仅为12，大大减少了不变量的计算量；本文同时证明单轴旋转运动的不变量可以通过最少两条二次曲线来确定，在这种情况下所需确定的参量个数仅为10，该方法是目前同类算法中参数最少的；本文提出了用多条二次曲线求解单轴旋转运动的不变量的最大似然估计算法，其所需确定的参量个数为6+2n，其中n为二次曲线的个数，该公式更深刻地反映了二次曲线与不变量的参数关系。

To reduce the sensitivity of conjugate initial values, the initial values of control variables are used to replace the initial values of conjugate variables based on the transformation between conjugation variables and control variables.

为了降低共轭变量初值选取的敏感性，引入共轭变量与控制变量之间的变换，用控制变量初值代替了共轭变量初值。

That not only could be extended to the continuous random varia- ble,but also the theorem of maximum information measure could be extended to the continuous random variable, which unified the measurement arithmetic of information between distributed random variable and continuous ran- dom variable,and gave two validating models to the information entropy of the continuous random variable in the last.

用公理化的方法，推导出了有限分布列的离散型随机变量的信息量系，不仅将它推广到连续型随机变量，而且将信息量系的最大信息量定理推广到连续型随机变量，统一了离散型和连续型随机变量的信息度量算法。最后利用得出的结论对连续型随机变量信息熵给出两个验证性算例。

When outcome variable is measured in the dichotomous form, the descriptive indices are often indicated for frequencies, percentages or proportions, correspondingly, the statistical inference methods are mainly χ2 test or the two-variable relationship analysis.

分组变量和结局变量均为二分类变量的研究在医学研究中是比较常见的，结局变量表示为二分类的形式，研究者通常采用频数、百分比或比例等统计指标描述，相应的统计推断方法主要为χ2检验或两变量之间的关联性分析。

For example, Keyfitz made the classification of the bifurcations in one state variable, without symmetry up to codimension 7; Golubitsky and Schaeffer obtained the classification of the bifurcation problems in one state variable with Z_2 symmetry, in one parameter up to codimension 3; Golubitsky and Roberts studied the classification of degenerate Hopf bifurcation in two state variables with dihedron D_4 symmetry, in one parameter up to topological codimension 2; Melbourne obtained the classification of bifurcations in three state variables with octahedral symmetry, in one parameter, up to

需要指出的是以上研究均没有考虑分歧参数的对称性，Futer，Sitta和Stewart的工作虽然考虑了分歧参数的对称性，但仅限于分歧参数与状态变量具有相同的对称性，他们得到了状态变量与分歧参数均关于二面体群D_4对称，拓扑余维数不大于1的分歧问题的分类。高守平和李养成则讨论状态变量和分歧参数均具有对称性且对称性可以不同的分歧问题，并给出了状态(来源：A770707BC论文网www.abclunwen.com)变量关于二面体群D_4对称，分歧参数关于S~1对称，拓扑余维不超过1的分歧问题的分类。本文第一章讨论两个状态变量关于二面体群D_3对称，两个分歧参数关于O(2)对称的分歧问题，给出了该类分歧问题在非退化条件q(0)≠0下所有情形的分类与相应的识别条来源：AdadaBC论文网www.abclunwen.com

According to that the eigenstates of applied quantum systems, are with discrete or continuous spectrum construction, quantum information is divided into two types of discrete variables and continuous variables. They have different features and application potentials. Both of them are parallelly developing.

量子信息科学根据所利用的量子变量的本征态具有分离谱或是连续谱结构区分为分离变量与连续变量两大类，连续变量和分离变量量子信息有着不同的特点与应用前景，各具特色，目前正在平行发展。

Correlation analysis and factor analysis indicated that two principal components were derived with each comprising 3 variables. The first principal component include the width of metatarsal trochlea II, III and IV; and the second principal component includes the relative height and anterior projection of metatarsal trochlea II compared to that of III, and relative anterior projection of metatarsal trochlea IV compared to that of III.

对现生鸟类跗跖骨5组（12个）变量进行分析，研究各变量间的相关程度，对变量进行主成分分析提取出2个主成分，其中第1主成分包括第II，III，IV三个跖骨的宽度变量；第2主成分包括：第II跖骨滑车相对于第III跖骨滑车的上下及前后位置两变量，以及第IV跖骨滑车相对于第III跖骨滑车的前后位置变量。

It points out the exterior impaction of export departments on non-export departments and the impactions of primary products export and industrial products export and reveals the essential characteristic of China's economic operation through the empirical results, thus analyzing the impact of export trade on China's economic growth objectively.

为了避免谬误回归的产生，本文从非平稳的实际变量来考察，将名义变量合理地转化为实际变量，然后利用ADF单位根检验各变量的平稳性，对于非平稳的实际变量，利用协整理论来分析变量之间的长期关系。

The problem with temps is that they are temporary and local.

临时变量的问题在于他们的生命周期都是临时的而且作用域是局部的，因为只在那些应用这些变量的方法的上下文中，他们才是可见的，所以临时变量更应该被封装成一个长一点方法，这是你延伸这些临时变量应用范围的唯一途径，通过用一个类似查询的方法来替换临时变量，类中的任何方法都可以访问临时变量所携带的信息，这对获得更清晰的代码有很大的帮助。
