The discrete choice of parking location and the continuous choice of parking duration take place at the same time and are influenced by many common variables. Therefore, treating parking duration as an exogenous variable in parking location choice model would result in inconsistent estimates.

其中包含了间断性选择与连续性选择，此二选择决策系同时发生，且受到许多共同变数的影响，视停车延时为停车区位选择的外生变数，将使得模式校估所得的参数值产生偏误。

The dissertation in depth analyzes the inner relationship between hedging and risk diversification, finds out that the relevance among prices or returns of different assets is the common basis for hedging and portfolio selection,and presents the notion of hedging portfolio selection referring to portfolio selection theory,which means that hedgers choose optimal hedging portfolio from a set of feasible hedging tools considering risky elements and hedger\'s real requirements during the course of hedging.

本文深入分析了套期保值与风险分散化思想的内在联系，指出资产之间价格的相关性是套期保值问题和资产组合选择问题的共同基础，提出应该在真正的资产组合选择理论意义上研究套期保值问题的研究思路，即在充分考虑套期保值过程中各种风险因素和套期保值者实际要求的基础上从可供选择的套期保值工具集合中选择最优套期保值组合，并称这种研究套期保值的方法为套期保值组合选择。

In the first study, 847 subjects were selected as seronegative for both HSV-1 and HSV-2, whereas in the second study the 2491 selected subjects were selected only on the basis of HSV-2 seronegativity.

在第一研究中， 847 个主题象seronegative 被选择了为HSV-1 和HSV-2，但是在第二项研究中2491 个选择的主题被选择了只根据HSV-2 seronegativity 。

Envisioning what life would have been like with an alternate spouse becomes difficult and increasingly irrelevant as you settle into the life you've selected."Once you make a choice in life, the unchosen alternatives evaporate," he says.

想象和你的选择之中的一个伴侣生活会是什么样子可能很困难，这会日益偏离你要习惯和你选择的新环境的主题，他说，&一旦你在生活里做出了一个选择，那么就让没有选择的那些选择慢慢蒸发&。

Chapter two gives a deep analysis on sex selection and attributes its root to the influence of the Confucian culture. Sex discrimination is the social origin of sex selection, and its economic reason is due to the backward of agriculture economy and the unsounded social security system. The conflict between the "birth control" policy and people's partiality of boys is the direct cause of sex selection. And the current science development provides the possibility of technology for sex selection.

第二章主要对生育性别选择的深层次原因作了进一步讨论，提出传统儒家文化的影响是性别选择的文化根源，性别歧视是性别选择的社会根源，农业经济的落后和社会保障体系的不健全是其经济根源，计划生育基本国策和强烈的男孩偏好之间的矛盾是性别选择的直接原因，而当代科学技术的发展为实现生育性别选择提供了技术可能。

They fail to define clearly the dimensions along which they are prepared to allow their customers to individualise their purchase. This leads to unnecessary cost and complexity. Dell and Swatch do not offer consumers infinite choice. They are not trying to be all things to all customers. In any case, consumers generally prefer to be told what their limits are, and then to be allowed free rein within them. Successful mass customisers first find out what limits their customers are happy to live within, and then organise their operations accordingly.

公司在明确允许其客户在多大尺度上定制他们的商品存在困难这带来了额外的成本和复杂度戴尔和Swatch对顾客提供的选择是有限的他们没有试图让顾客进行无限选择总之，客户大多喜欢被告是什么是可以选择的，而什么不能，然后在可选择的范围内自由发挥成功的大规模定制公司首先要找出在不剥夺其客户选择乐趣的限制范围，然后在根据这个范围来进行下一步

The Inverse option lets you select all the clips and shots that are not selected, and deselects all selected clips and shots.

反向选项让你选择当前没有被选择的片段或快照，而已选择的则取消选择。

The Principal componants analysis shows that the main gene of the red crane to habitat selection is the food, veil water and vegetation, for the white crane, food and veil are the main gene, for the white nape crane, the main gene are food ,water and vegetation, for white head crane are veil water and vegetation, however, food, veil and vegetation are the main gene for the common cranes habitat selection.

对五种鹤的主成分分析表明丹顶鹤对生境选择的主因子为食物因子、隐蔽因子、水因子和植被因子；白鹤对生境选择的主因子为食物因子和隐蔽因子；白枕鹤对生境选择的主因子为食物因子、水因子和植被因子；白头鹤对生境选择的主因子为隐蔽因子、水因子和植被因子；灰鹤对生境选择的主因子为取食适宜性因子、隐蔽因子和植被因子。

Consulting the relevant information, the engine CZ4102Q made in Changzhou Diesel Engine Factory is chosen according to the full-load speed characteristic. The clutch adopts dry single-plate diaphragm spring one which is operated by hydraulic pressure system. The choices and arrangements of rear axle, steering gear, propeller shaft, differential and brake, etc is referred to the related parts on BJ1041 light truck.

发动机的选择是经查阅资料在其现有的外特性曲线上选择的常州柴油机厂CZ4102Q 发动机；离合器的改装设计选择了膜片弹簧液压式操纵机构单片干式离合器；后桥、转向器、传动轴、差速器和制动器等部件的选择和布置参照了BJ1041 轻型载货汽车的相应部件选择和布置设计。

As PTDT does in threshold traits, PTDT is valid not only for different QTL effect level, but also for maker with multiple alleles and multiple tightly linked markers.(2) Under an appropriate selection ratio s (in this study, s is 0.2, 0.4, 0.6, 0.8, respectively), the power of PTDT can be improved and the genotying individuals can be decreased using selective genotyping design. However, the power of PTDT is related with population size and population structure, an appropriate selection ratio can be defined by simulation based on the existing data.(3) Among the three transforming methods, mixed-family selection is the best, full-sib selection has same power to mixed-family selection in many parameter combinations, and Estimated Breeding Value selection is inferior to them.

数量性状QTL定位的模拟研究结果表明：(1)数量性状经有效转化后，PTDT对数量性状QTL定位保持了阈性状QTL定位的稳健与高效，对不同效应大小的QTL(10％，30％，50％)PTDT都是一个有效的分析方法；(2)在多等位基因标记、多标记方面，PTDT的检验功效与阐性状分析时一样高效；(3)在合适的选择率下(本研究的分别为0.2，0.4，0.6，0.8，1.0)，选择性基因型测定不仅可以减少基因型测定的数量，而且可以提高PTDT的检验功效，但选择性基因型测定的PTDT检验功效很大程度上与群体大小和结构有关，这个可根据具体情况通过模拟找到一个合适的选择率；(4)三种转化方法的转化效力结果表明，家系内混合家系选择的转化效力最高，家系内全同胞选择次之，估计育种值选择的转化效力较差。
