Firstly, cross donor and recipient lines to produce F1; secondly, repeated backcross the F1 individuals and the subsequent progenies with the recipient to recover its genetic background; and thirdly, intercross the backcrossed progenies to fix the introgressed genes in the population.

在标记辅助导入过程中，标记信息既可用于辅助前景选择，即对目标基因携带者的选择，以保证目标基因的正确导入，也可用于辅助背景选择，即对受体基因组的选择，以加快受体遗传背景的恢复。

In order to improve the resistance to bacterial blight of high quality rice male sterile line Jinshan A , in this study, the Jinshan B and IRBB21 that carried gene Xa21 were used as parents to make backcrosses, and both foreground selection and background selection were carried out by means of marker assisted selection in the backcrosses.

本研究以IRBB21为Xa21基因的供体亲本，以金山B为轮回亲本进行回交，并应用分子标记辅助选择技术对回交各世代同时进行前景选择和背景选择，得到如下结果：(1)利用Xa21基因内的STS标记MXA21对各回交世代进行前景选择，得到了44个带有Xa21基因的BC_1单株和40个带有Xa21基因的BC_2单株。

The preference soil pit was contour line pit, the second choice was soil digging at slope bestriding ridge, and the last selection was soil digging at slope without striding over ridge. And the preference residue pit was low-lying, next was flat pit, and the last choice was ditch or slope pits.

提出了借土场和弃渣场的优先选择方法：借土方式应优先选择沿等高线借土，跨山脊坡面借土次之，最后考虑不跨山脊坡面借土；弃渣方式应优先选择填洼弃渣，平地弃渣次之，最后选择沟道弃渣或坡面弃渣。

The optimum technical parameters were obtained as follows:bromating temperature is 15℃,solvent is methyl arcohol, bromating agent is BrCl,the molar ratio of 4-hydroxy-benzaldehyde to BrCl is 1:1.15,reaction time is 2.5 hours.

其工艺参数优化如下：溴化时反应温度选择15℃，溶剂选择甲醇+乙酸甲酯，溴化剂选择氯化溴，对羟基苯甲醛与氯化溴之比为1∶1.15，反应时间选择2.5个小时，滴溴时间约半个小时。

The utility function of the integrated model was divided into two stages, choice set and alternative choice. The specification of factor structure was used to capture the individual heterogeneity and marketing positioning of the alternatives in the second stage, and the effects of new modes on choice behavior and market structure were studied by hypothesizing coefficients' specifications in the joint estimation process.

整合性模式的效用函数区分为选择集合及方案选择两阶段，而於方案选择效用函数中以因素结构的指定方式，考量个体偏好的异质性与方案的市场定位，并藉由联合估计过程中的系数假设，分析新运具对於旅运选择行为及市场结构的影响。

There is new option called 'Enable Localizes Clusters' , which when selected can carry out more advanced calculations when you add and subtract using the selection eyedropper tools to refine a Color Range Selection.

有新的选择所谓的'启用查找集群，这时候选择可以开展更先进的计算时，加减使用选择滴管工具，以完善彩色范围选择。

One analogy is labyrinth, although you will face multiple choices from time to time, you can only choose one at a time without knowing where the other routs leading to.

因为在经典的设计过程中，对于每个阶段的选择方案你都需要做一个决定，只能选择一个然后向下发展，就像走迷宫，虽然你也会不断地发现很多选择，但每次你只能选择一条路走下去，永远无法知道其他路通到哪里。

By Panzhihua Steel Vanadium today announced that, in order to encourage more of Panzhihua Vanadium Steel shareholders have the right to choose to choose to continue holding company stock, to encourage more climbing the Great Wall shares of Chongqing Titanium and shareholders have the right to choose to participate in convertible , Anshan Iron and Steel Group to make further commitments: Anshan Iron and Steel Group will "on the right to declare the cash option exercise period of the deadline for undeclared cash to exercise the right to choose have the right to choose shareholders," added the right to declare a cash option to the right line.

由攀钢钢钒今天宣布，为了鼓励攀钢钢钒的股东有更多的选择权，选择继续持有公司股票，以鼓励更多攀登长城重庆钛和股东的股份有权选择可兑换，鞍山钢铁集团公司参与做出进一步承诺：鞍钢集团将&对有权宣布现金选择了未申报行使现金期限内行使选择权的有选择权股东，&将有权宣布现金选择正确的路线。

The yarn change device for selecting a yarn at a location between a plurality of kinds of feeder packages of different color or the like and the feeder of a knitting machine and feeding the yarn to the feeder of the knitting machine while piecing the selected yarn and a yarn being knitted, comprises a suction means (28) for suction-holding a plurality of yarns collectively, and a clamp means (29) for clamping the plurality of yarns collectively at a location between the suction means and the feeder packages, wherein the clamp means comprises first and second clampers (29A, 29B) arranged at two positions along the thread handling area and operating selectively.

该纱线切换装置在颜色等不同的多种喂纱筒子和织机的喂纱装置之间选择纱线，并把被选择了的选择纱与织成中的织成纱进行接头，从而向织机的喂纱装置喂纱，具备：将多根纱线一并吸引而保持的吸引机构(28)、以及在上述吸引机构与上述喂纱筒子之间将多根纱线一并夹持的夹持机构(29)，上述夹持机构沿着纱线道而被配置成两处，包括选择地动作的第一夹持器(29A)和第二夹持器(29B)。

The paper concludes that:in addition to the influences from the factors of corporate and auditor,the corporate's auditor selection is influenced by the interlocked corporates' selection;the mechanism of influence is two aspects:the one is that the interlocking directorates is just the deciders who select the audit...

本文认为：企业在选择会计师事务所时，除了受到事务所和企业两方面因素的影响外，还受到联结企业事务所选择的影响；受联结企业影响的机制有二：一是形成联结企业关系的连锁董事和选择会计师事务所的决策者为同一主体；二是尽管有时主体不同，但在企业选择会计师事务所时，会受到联结企业的信息影响和社会影响。
