Based on a thorough analysis of the experimental results, a coupling mechanism of the catalytic selective oxidation and non-catalytic partial oxidation in which the surface adsorbed 〓 species and the lattice 〓 species take part synergically.

在全面分析实验结果的基础上，提出了一个由表面吸附氧种〓和晶格氧种〓协同参与的甲烷催化选择氧化与气相非催化部分氧化相耦合的反应机理，催化剂的参与既在表面开辟了生成〓和HCHO的新途径，又可将气相反应中的强氧化型物种转移到催化剂表面，形成有利于选择氧化的表面活性氧种，同时避免了气相中强氧化型物种浓度过高而导致选择氧化产物深度氧化。

So, it is difficult to be explained by reasonal choice theory .but it has suited the perceptual regulation of perceptual choice theory .Look from its concrete recruitment behavior and incentive mechanism, they are not accord with reasonal choice theory, but embody such characteristics of choosing by tradition , choosing by experience and choosing by characteristic of goal totalization .

因为，国有企业的招工行为是对马克思主义理论的照搬照抄，是对苏联企业模式的模仿，同时它还是在计划场域制约下，遵循实践意识的行为选择；而国有企业选择统一工资政策和企业办社会的福利模式作为服务于用工的激励机制，其行为选择既受计划场域的制约，同时也受中国传统思想的影响。

There are two aims of the article: one is to trace the trajection of education and professional choice of those women doctors who were either migrant from China or bone locally and both worked in Taiwan in early 1950. Through the discussion of familiar influence on individual choice, it argues that individual choice is not real individual choice but a results of the constraint of cultural values, gender relations and educational and professional systems.

本文有二个目的，一是藉著追溯1950年代在台湾行医的台湾本地与中国移台女医师的教育与职业选择的过程，藉著讨论家庭影响个人所做的抉择，企图说明个人的教育与职业的选择其实不是个人的选择，而是受到当时的文化价值，性别关系，教育和职业制度的限制。

Also, a large array of options may diminish the attractiveness of what people actually choose, the reason being that thinking about the attractions of some of the unchosen options detracts from the pleasure derived from the chosen one.

同样，大量的选择也会减弱所供选择的商品对消费者者的吸引力，原因在于未被选择商品的诱惑会减弱消费者从已选商品中获得的快乐。

The essence of liberty has always lain in the ability to choose as you wish to choose,because you wish so to choose,uncoerced,unbullied,not swallowed up in some vast system;and in the right to resist,to be unpopular,to stand up for your convictions merely because they are your convictions.

译文是：自由的本质一直在于根据你选择的意愿去选择的能力，因为你愿意像这样进行选择，不受强制，不受胁迫，没有被一个庞大的制度所吞噬；为了你的信念而正确地抵制、不怕得罪人、挺身而出，做这一切只因为它们是你的信念。

The essence of liberty has always lain in the ability to choose as you wish to choose, because you wish so to choose, uncoerced, unbullied, not swallowed up in some vast system; and in the right to resist, to be unpopular, to stand up for your convictions merely because they are your convictions.

译文是：自由的本质一直在于根据你选择的意愿去选择的能力，因为你愿意像如许进行选择，不受强制，不受勒迫，没有被一个庞大的制度所吞噬；为了你的信念而正确地抵制、不惮患上罪人、挺身而出，做这一切只因为它们是你的信念。

With proper atomic coherence, the performance has the following advantages compared with that of the velocity selection of the ultracold two-level atoms by the micromaser: high resonant transmitted efficiency, low unresonant transmitted efficiency, and large velocity selection scale. The second part includes the fifth chapter.

原子透射几率只受到一种量子干涉效应的影响，其来源为V型的两个跃迁通道，因此Micromaser对入射超冷V型三能级原子束速度的选择性能深深地受到原子相干性的影响，我们发现选取适当的原子相干参数以及其它参数，速度选择性能可以达到很理想的状态：共振原子透射效率高、透射原子束的速度纯度好、速度选择范围大。

Design of drainage system discharges the way of draining water and the sureness of the system to include; calculation of the water force of the pipeline, mainly includes the design of the crosswise pipe slop and pipe diameter and the design of the vertical pipe diameter; the design of the way of ventilation and the calculation of the ventilative pipe; the design of the inspection shaft to choose the sewage waste water pump.

本建筑为河南省某管理局综合办公楼，对给水排水系统的要求较高。主要设计包括：给水方式的确定，竖向分区的合理划定，管材的确定，管道的水力计算，加压设备和贮水设备的选择计算。排水系统的设计主要包括：排水体制及其排水方式的确定；管道的水力计算（主要包括排水横管的坡度管径的确定，竖管管径的确定）；通气方式的确定以及通气管道的设计计算；集水坑的选择计算并由此选择潜污泵。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
