Basing on the traditional definition about trip-chain, the paper has defined a start point and end point standard in the commuters on-off duty trip-chain, and by utilizing the analysis method which based on trip-chain, the paper presents the discrepance about trip-chain type selection behavior as the commuter has different socity and economy background.

在传统出行链定义的基础上，界定了通勤者上、下班出行链开始和结束的标准，利用基于出行链的分析方法，比较了不同社会经济背景下通勤者对出行链类型选择的差异。

A novel hybrid algorithm, which combines predictor-corrector primal-dual interior point method and genetic algorithm, is presented for dynamic and static reactive optimization in this dissertation. The algorithm fully make use of the advantage of interior point method in solving successive optimization problem and the advantage of genetic algorithm in solving discrete optimization problem. The original problem is divided into three parts: total successive problem, discrete problem and successive problem.

结合内点法和遗传算法，本文提出了一种新颖的混合算法用于求解动、静态无功优化问题，算法充分利用了内点法易于求解连续优化问题和遗传算法易于求解离散优化问题的优势，将原优化问题分解为初步的连续优化问题、离散变量优化问题、连续变量优化问题这三个子问题分别求解。

Point clouds are discrete data points without the topology relationship between them. So, to facilitate and expedite the extraction of contour points for the late NPR style, firstly we should simplify the point cloud data. In other words, non-contour points should be eliminated but their contour points and feature points should be retained .

点云数据本身是无拓扑关系的离散数据点集，所以，为了方便和加速后期非真实感绘制风格化所需轮廓点的提取，首先对点云数据进行了"粗略"地简化处理，即剔除点云数据中非轮廓点保留了其轮廓点和特征点；然后应用判定准则提取出所表示物体的轮廓点并对其进行"归并"形成便于NPR风格化处理的特征轮廓线；最后再对得到的轮廓线进行NPR风格化效果"加密"处理。

Agricultural non-point source pollution is entirely different from that of point sources in their generation and transportation, so special methods have to be derived to internalize its external diseconomy.

农业非点源污染是典型的负外部行为，但非点源污染的发生与点源污染有着显著不同的特征，这就决定了非点源污染外部性内部化方法的独特性。

B The bearing and distance of the course altering point and from the course altering point to the target.

到转向点的距离和从转向点到目标的距离。

Or simply just measure the distance between point A and point B.

它还可以直接测量出点A和点B之间的距离。

The bearing and distance of the course altering point and from the course altering point to the target.

到转向点的距离和从转向点到目标的距离。

The set of points surrounding a specified point,each of which is within a certain ,usually small distance from the specified point.

邻域定点周围的点的集合，其中每个点离定点在一定的，通常是很小的距离内

We use the Taylor series expansion method to get the second-order approximate expression of the confidence region of the parameters, and then according to the principle of minimizing the volume of the confidence region, this paper carries out experimental design for the regression model, and then fixes the point range in the domain of definition of design variable for the model function so as to select the designing point, which can minimize the volume of the confidence region.

文章首先计算指数族非线性模型的回归参数β在1-α置信水平下的置信域的体积，为了便于计算，需把置信域投影到切空间中去，投影后的置信域是一个椭球体，用Taylor展开方法对此椭球体的体积进行二阶近似，推出原参数置信域的体积的近似表达式，然后对回归模型进行试验设计，根据置信域体积最小准则，在模型函数的设计变量的定义域上确定点列，选取使置信域体积达到最小的设计点。

I thought once--I meant once to--to make her an offer by and by, when this horrible mystery about George Talboys should have been cleared up and everything peacefully settled--but now-- His thoughts would ordinarily wander away at this point of his reflections, carrying him where he never had intended to go; carrying him back under the pine-trees in Dorsetshire, and setting him once more face to face with the sister of his missing friend, and it was generally a very laborious journey by which he travelled back to the point from which he had strayed.

我一度想到过——我的意思是我一度想到过将来慢慢的要向她求婚，那时候关于乔治·托尔博伊斯的可怕的秘密搞清楚了，一切都和平解决了——可现在——他的思想考虑到这一点时，往往游离开去，把他带到了他最不想去的地方；把他带回多塞特郡梨树下，让他跟他失踪的朋友的妹妹面对面地相会；而他要回到已经游离的这一点上来，通常总要经过一段辛苦艰难的路程。

You can buy sweetened beverages, if that suits you.

你若喜欢的话，可以买些含有糖精的混合饮料。

As many of you are probably aware, Nick and Vanessa were recently faced with an embarrasing sex scandal after naked pictures of the two getting jiggy with it in a hot tub surfaced the net.

正如很多你可能知道，尼克和 Vanessa 最近面临一个尴尬的绯闻事件后，赤裸裸的图片两个越来越jiggy与它在浴缸中的一个热点浮现净。
