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

Perhaps the giving up is the best choice, lets choice which oneself extricates; Let all become the tranquil choice; Let me return to the study choice, perhaps with is lets my happy choice

放弃或许就是最好的选择，让自己解脱的选择；让一切都变得平静的选择；让我回归到学习的选择，或许跟是让我幸福的选择…。

DiSEqC mode is for port selection of the four-way DiSEqC switch.

卫星项选择要设置的卫星，LNB类型所用高频头单双本振的选择，LNB电源选择开，选择高频头的本振频率，0/12V选择0V，22KHz 为22KHz切换器选项，DiSEqC模式为四切一端口选项。

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.

Rather than comfortably nibbled away by conventions and commonplaces in a familiar environment, it is far better to struggle to break out of it, bring new value to your life, and raise your professional standing.

不要指望人生道路或事业的选择能一锤定音。也许你第一次选择时以为是那样，而选择后你发觉并非那样，这时你得果断地进行再次选择。&选择&本身不是惟一，目标才是惟一的。

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。
