挥发的

One reason for the appeal of the giant-impact scenario is that it seems to explain all the chemical findings from Apollo.For example,the moon rocks lack water,sodium and other volatile materials-precisely the substances that would boil away in the rapid vaporization after impact.

这个&大爆炸&理论演示实验吸引人的一个原因是它似乎解释了从月球带回来的所有化学发现物，例如，月球上缺水，钠和别的易挥发物质——精确地讲，这些物质在碰撞之后在迅速的蒸发中被烧干了。

The best current thinking is that volatility (elements and compounds, including water, vaporize at low temperatures) were released from the solid phase as the earth accreted.

当前最通行的观点是挥发物(元素和化合物，包括低温下蒸发的水)在地球增生形成时的固体阶段就被释放出来，然后地球、海洋和大气逐渐连成一个整体。

Objective To determine the oviposition responses of Anopheles sinensis to bacteria A4, Aeromonas sp. and Enterobacter sp. and whether or not the three strains attracted the mosquitoes, providing theoretical and experimental evidence for the application of the three bacteria in the intervention of malaria. Methods Blood?fed and held for 48-60 h, copulated female An.

目的 具吸引作用的细菌或其挥发物能提高按蚊与杀虫或抗疟工程细菌接触的机会，为此，拟测定中华按蚊对A4细菌、气单胞菌和肠杆菌的产卵反应特性，以明确3种细菌对中华按蚊是否具有吸引特性，为应用这3种细菌开展阻断疟疾传播研究提供理论和实验依据。

The anion has as follows 8 big benefit: Sterilize surpass the oxygen negative ion free radical but kill various pneogaster infectious disease bacterium; Dust removal makes air middle dust heavy getting together, suspension pellet the brute force is collected; Deodorization dislodges various the peculiar smell living , bad smell , improves a bag; Eliminate cigarette smoke fog , dust in wiping out air rapidly , completely eradicate the second-hand cigarette; The various deleterious chemistry volatilizes a gas , wipes out "the invisible killer " in getting rid of poison dislodging air; Work efficiency, removes health care rise becoming fagged , improve the heart-lung function, strengthen the human body immunocompetence; Improve the looks making an epithelium bring negative charge along , make germs lose the go at ability to the cell , keep skin glossy; Except that static electricity is positive static electricity in general in life, will be physically and mentally healthy to the human body bringing about hidden trouble, the anion has an effect to neutralize this static electricity.

负离子有如下8大好处：杀菌——超氧阴离子自由基可杀灭各种呼吸道传染病菌；除尘——使空气中尘埃聚沉，强力收集悬浮颗粒；除臭——去除各种生活异味、臭味，改善生活环境；消烟——快速消灭空气中的烟雾、尘埃，杜绝二手烟；去毒——去除空气中各种有毒化学挥发气体，消灭&隐形杀手&；保健——提高工效、消除疲劳，改善心肺功能，增强肌体免疫能力；美容——使上皮细胞带负电荷，使病菌失去对细胞的攻击能力，保持皮肤光滑；除静电——生活中一般为正的静电，会对人体身心健康带来隐患，负离子有效中和这种静电。

The dose of γ-irradiation had significant influences on shelf life of boiled dumplings under chill state. The value of volatile basic nitrogen of control sample excessed the trade standard after one week. The value of total acidity of control sample excessed the trade standard after four weeks.However ,except TBA of sample treated with 5 kGy excessed the trade standard after irradiation, other properties of treated sample were all well within the acceptable level throughout storage period.

未辐照处理产品贮存至 7 天时挥发性盐基氮含量超标，除 5kGy 辐照产品的 TBA 值在贮存前期超标外，其他各辐照处理产品各项安全质量指标在 21 天贮存期内均未超标；与对照样比，剂量越高，所分析指标变化越小；对照样只有 7天的货架期；2 和 3kGy 辐照在 14 天时感官评分值降至可接收值底限；4kGy 表现出最佳贮藏效果，可获得 21 天的货架期。

On basis of long duration successive test with one pilot scale test facility,the effects of fluidizing velocity,particle size and air distribution on the combustion behavior were discussed in detail,as well as agglomeration phenomenon in ...

结果表明，颗粒度大小影响秸秆挥发分的析出以及传热过程，密度大小影响到原料的循环以及传热系数，表面粗糙度直接影响到秸秆的辐射换热。

The concentration of the gas could be achieved by measuring the change of the conductivity. In the experiments, the gas sensor was prepared by spreading the water solution of carbon nanotubes between the interdigitated Au electrode, which was splashed on alumina. In this paper, three methods, such as mixing palladium and copper chloride, deoxidizing palladium and copper by chemical and electrochemical means, were used to doping palladium and copper in multi-wall carbon nanotubes.

实验中我们采用单壁和多壁纳米碳管作为敏感材料，在叉指金电极间涂布纳米碳管悬浊液作为气敏膜，用于有机挥发物如甲醛、苯、甲苯和二甲苯的检测，并着重研究了掺杂氯化钯和氯化铜盐溶液、化学和电化学方法掺杂钯和铜金属颗粒对多壁纳米碳管传感器的气敏性能的影响。

Sweat back: A condition caused by unbalanced fast drying and the slight volatility of the ink vehicle, in which, oil was transpired out on the surface of the dry ink, causing sticking, resist overprinting and lead to lamination failure.

墨汗：从干墨中渗出油的情况。这是因为油墨的展色剂具挥发性，加上不平衡的快速干燥而致。墨汗会引致黏纸，拒墨，裱胶失误等故障。

This product has the strong volatile gas also has the strong irritant smell, when the work should pay attention ventilates as well as the far away open fire.

注意事项：本产品具有强挥发性的气体，有较强的刺激性的气味，作业时，应注意通风以及远离明火。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
