选择性

Now we have a wide range of alternatives.

现在我们有一个广泛的选择性。

In the second part of this thesis, we calculate the common mesophases for the ABm star copolymers.

在本文的第二个部份我们计算出ABm星状共聚物在弱选择性溶剂中的相行为。

China's missing-women problem was usually ascribed to the aborting of girl babies, female infanticide and neglect.

中国的"女性缺失"问题通常被归咎于选择性堕胎、女婴遭扼杀和遗弃等原因。

Comparing to the traditional prenatal diagnosis,PGD is a method that can avoid aborting a abnormal pregnant and reduce pains of women.

与传统的产前诊断相比，能避免选择性流产异常妊娠给妇女带来的心身痛苦。

If a mother's stress adversely affects the development of her fetus then selectively aborting boys, rather than wasting time and resources on bringing them to term, would make evolutionary sense.

如果母亲所受的压力对胎儿的发育有相反的作用甚至选择性的流产男婴，而不是使得孕妇浪费时间和资源将他们抚养成人。这将极具进化学意义。

If... then selectively aborting boys...would make sense.

如果母亲的压力对胎儿的发展起了相反的影响，选择性地将男孩流产，而不是浪费时间和资源将他们养足月，那么就能说明进化的问题了。

In principle, the protocol developed in this study could be used for detecting other foodborne pathogenic bacteria such as E.coli, Staphylococcus, Campylobacter and food toxins such as Ricin, Abrin, or Clostridium Botulinum if the proper antibody is selected for the conjugation with nanorod substrates.

大致上，这项研究兴盛的草案可以通过选择性结合在纳米棒底层的相对性抗体被用于检测另外一些食源性病原菌，比如大肠盖希氏菌，葡萄球菌，弯曲杆菌和食物毒素，诸如蓖麻毒素，红豆因或肉毒梭菌。

This article analyzed characteristics and development trend of FCC gasoline in China, introduced the characters and plant effects of OCT-M and FRS FCC gasoline selective hydrodesulfurization process, especially the commercial application effect of the production of States Ⅲ and Ⅳ regulation gasoline. The commercial test results showed that OCT-M and FRS process were mature and credible, and had the characteristics of low pressure, low investment, convenient operation, low H2 consumption and high liquid yield. OCT-M and FRS process could offer refineries optional economical and flexible measure to produce States Ⅲ and Ⅳ regulation clean gasoline.

分析了我国FCC汽油的特点及发展趋势，介绍了OCT-M和FRS FCC汽油选择性加氢脱硫技术特点及中试效果，着重介绍了OCT-M和FRS FCC汽油选择性加氢脱硫技术生产国Ⅲ、国Ⅳ汽油的的工业应用效果，标定结果标明，OCT-M和FRS技术成熟可靠，具有装置压力等级低、投资省、操作方便、氢耗低、汽油产品收率高等特点，是我国炼厂生产国Ⅲ、国Ⅳ清洁汽油时可供选择的经济、灵活的解决方案。

Cereus group strain was investigated in this paper. The result confirmed that MYP and PEMBA medium had high selectivity for this bacterium.

对三种常用BC选择性培养基进行了比较，证明MYP及PEMBA对Bc群微生物有良好的选择性。

In order to disclosure the reason why the electrocatalysis activeness and selectivity droped after being used several hundred hours continuously, the x-ray diffraction, scanning electron microscopy and energy dispersive spectroscope have been used to characterize the surface condition variations of Monel metal. The results indicated: Monel metal belongs to the Cu-Ni alloy around the electrolysis experiment.And after being used for 600hr, the surface layer element composition and geometry distribution of the alloy changed, namely in the alloy the Cu element /which superficial free enthalpy was smaller,"concentrated" to the alloy surface,and formed one kind of marble structure microcrystallite.Thus the electrode surface becamed rough a

为了揭示蒙乃尔合金阴极在连续使用数百个小时后电催化活性剂选择性下降的原因，采用X射线衍射仪、电子扫描电镜和电子能谱分析仪对电解实验所用的蒙乃尔阴极材料在电解实验前后的表面状态进行了表征，结果表明：所使用的蒙乃尔合金阴极材料在电解实验前后均属于Cu-Ni合金，使用600hr后，由于表面层元素组成和几何排布发生了变化，即合金中表面自由焓较小的Cu元素向合金表面&富集&，形成一种大理石结构的微晶，表面粗糙、不均一，这是造成其对硝基苯电还原的催化活性及选择性随着使用时间延长而逐渐下降的主要原因，同时也为此类电极的修饰改进提供了方向。

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
