In this paper, a uniform framework of feature model is presented from the aspects of basic structure, variability representation and constraint mechanism, and variability binding time.

从特征模型的基本组织结构、变化性的表现方式和限制机制、变化性的绑定时间等方面对特征模型的组织框架及剪裁机制进行了统一、抽象的描述。

The common SVD algorithm was briefly discussed and analyzed on the basis of vector space,and a new iterative scheme was proposed to achieve the nonnegative constraint.Based on this scheme,the SVD inversion algorithm was improved.

摘要介绍了核磁共振T2谱传统奇异值分解反演算法，从向量空间的角度对算法进行了分析，提出了一种新的实现非负约束的迭代方案，并根据这个方案改进了传统的SVD反演算法。

We first state general linear model, ridge-type estimator and general ridge-type estimator, and the constraint biased estimator. And then, we introduce some basic theory about matrix and some conclusion about the admissibility of estimator in Gauss-Markov model. In the third chapter, we discussion several equivalent characterization of the best linear unbiased estimation, we proved that admissible characterization of admissible of linear estimation is as conditional general ridge-type estimation in general linear model. A necessary and sufficient condition that homogeneous linear estimator is admissible estimator is obtained.

本文首先概述了一般线性模型，岭估计及约束岭估计的发展历史和研究现状，在第二章介绍了矩阵的一些基本知识和可容许性的一些基本结论，第三章讨论了一般线性模型最佳线性无偏估计的几个等价条件，以及线性估计的可容许性特征，得到了一般线性模型的可容许线性估计均具有条件广义岭估计的形式，给出了一个齐次线性估计为可容许估计的充分必要条件。

With the regional indexes of reference crown height and environmental factors including topographical, geomorphic, soil, climatic, geographic, standing condition and so on, by establishing GIS and with PCA and bidimensional step cluster with constraint condition, ecological region with the unit of town or land forest farm can be realized.

摘 要：采用红松基准上层高及环境因子地形、地貌、土壤、气候、地理、立地条件等为区划指标，通过建立地理信息系统和应用主成分分析、有约束条件的二维逐步聚类方法，实现了以乡为区划单元的生态区划。

Secondly, taking the constraint curve of spherical R-R binary as the unique element, kinematic synthesis for spherical mechanism is discussed.

其次，以球面机构R-R二副杆的约束曲线为综合要素，表述了球面机构综合理论与方法。

Having everyone read The Goal helped everyone understand that the basis for everything we do wasn't localized thinking anymore. So, for example, if a job had to spend a little more time in the bindery, that's okay, as long as that's what's most effective for the press, which we had identified as the major constraint. In the end we got the throughput that we needed.

大家都读过《目标》，就明白到我们所做的每件事，都不再基于局部效益的思维了，所以，比如说，有一项工作需要在装订部多花一点时间，没问题，只要这样做对主要的制约因素是有利的就行了，最终，我们就拿到了我们需要的有效产出。

Especially, the water-filling method with the integer bit constraint is researched and a modified greedy method and a bisection bit allocation method are proposed, respectively.

重点研究了在实际系统中整数比特约束下的注水法则，提出了一种改进的贪婪算法和对分比特分配算法。

A new random CSP (constraint satisfaction pro blem) model is proposed in this paper.

In this paper, we put forward a 2.5D model based on the hexahedron and developed an inversion method of constraint gravity-vertical fault. The inversion result is better than that the 2D model through the model tests. Based on this model, we quantitatively interpreted the Bouguer gravity anomaly of the Sierra Nevada Region in the USA.

本文从六面体模型出发，将二度体模型修改为似二度体模型，建立了一个带约束的重力－垂直断层反演模型，经过理论模型试验，证明效果要优于二度体模型的反演结果，在此基础上对美国内华达州的圣安德烈斯地区的布格重力异常资料做了定量解释。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
