Photodissociation of alkyl bromides has been a popular area of investigation, in view of their ozone depletion potential and of the fundamental interest in photodissociation dynamics.

溴代烷烃的光解近年来已成为十分活跃的研究领域，一方面是由于溴代烷烃的光解产物溴对臭氧层的破坏，另一方面是由于溴代烷烃光解研究的理论意义。

This paper mainly inquired into the characteristics of the ferment bed pig - raising technique and its applying in realizing the cleaner production of pig farms. ferment bed ; cleaner production ; pig - raising technique ; waste treatment

但由于发酵床技术主要靠微生物降解猪场废物，而目前所使用的菌种分解效率不是很高，使得单位面积饲养的猪数量有限，另外由于猪舍是半开放式的，受外界的环境变化的影响，如何使菌种在不同的气候条件下都能发挥较高的效率也是一个需要解

Because the simple Pitot tube (Figure 4.3.19) only samples a single point, and, because the flow profile of the fluid varies across the pipe, accurate placement of the nozzle is critical.

由于简单的皮托管（图4.3.19 ）只样品单点，而且，由于流动剖面流体有所不同的管道，准确位置，喷嘴是至关重要的。

As expected, 2 was not gelled but precipitated under such conditions that brought about the gelation of 1 because the molecular stacking between the HPB units was interfered with due to the lack of planarity.

正如预期的那样，二是不发胶但是沉淀条件下所带来的 1由于凝胶分子量HPB之间的叠加单位是干扰由于缺乏planarity。

Due to AACs unique cell structure and absorbing water propriety, However, There are still many problems, when we adopt ordinary mortar to construct and plasterer ash, such as wall crack, big area of layer of plasterer ash crack and partially hollow drum, even according to present AAC technical specifications, for the actual operation craft is so complicated that It is very to guarantee each preface quality.

然而，由于加气混凝土本身特有的多孔结构和吸水特性，采用普通砂浆砌筑与抹灰，即使按现行加气混凝土砌块施工规定的方法施工，由于实际操作工艺复杂，各工序质量难以保证，依然有墙体开裂，抹灰层大面积龟裂和局部起鼓、空壳、脱落等现象。

Studies discover that the minimal deposition threshold is 20eV and the maximum is 60eV with the different incidence point locations and incidence postures of C36 clusters. When the incidence angle is not over 60, C36 may roll or slip to the region of smaller bonding energy and then bond. So the bonding probability is raised.

研究发现：由于C36入射点位置及入射姿势的不同，其在金刚石（100）晶面沉积时的沉积阈值最小值为20eV，最大为值60eV；在入射角不超过60°斜射时，由于水平运动分量的存在，C36可能翻滚及平滑至成键能量较小的区域后再成键，因而提高了成键几率。

The results show that a separate dunk is observed near the stagnation point of the second sphere on the distance of spheres L≤2.5D because of the influence of reverse pressure gradient.

结果表明：当L≤2.5D时，由于逆压梯度的影响，在第二个圆球滞止点附近捕捉到附体分离泡；由于第二个与第三个圆球的置入，展向压力梯度诱发第一个圆球背风面流动的展向输运，且随着圆球间距的增加流场的展向输运趋势减小，但涡的强度增大；第二个圆球与第三个圆球背风面流动没有明显的展向输运；湍动能的增量与圆球间距近似成平方规律。

So it was that the farm poor were caught in their own past, the double victims of technology: exile from their home by advances in agricultural machinery; unfitted for life in city because of the consequences of industrial mechanization.

农民由于农业机械的发展而被赶出自己的家园，又由于工业机械化的结果又使他们不适合在城市生活，农民就这样成了技术发展的双重牺牲品，陷入旧日的困境中。

I was loath to spend our last shot too hastily; so I called my servant, not my man Friday, for he was better employed; for with the greatest dexterity imaginable, he had charged my fuse, and his own, while we were engaged; but as I said, I called my other man, and giving him a horn of powder, I bad him lay a train, all along the piece of timber, and let it be a large train; he did so, and had but just time to get away, when the wolves came up to it, and some were got up upon it; when I snapping an uncharged pistol, close to the powder, set it on fire; those that were upon the timber were scorched with it, and six or seven of them fell, or rather jumped in among us, with the force and fright of the fire; we dispatched these in an instant, and the rest were so frightened with the light, which the night, for it was now very near dark, made more terrible, that they drew back a little.

我不愿匆匆放最后的一枪，就叫来了自己的仆人，但不是"星期五"；"星期五"正在做更重要的事，在我们忙碌的时候，他以惊人的速度给我和他自己装弹药。所以我叫的是新雇的仆人，我给了他一角火药，命令他把火药铺在长木头上，铺成一条又宽又厚的火药线。他照着做了。他刚离开，狼群就冲了过来，有几只已经上了长木头。我拿着我没有开过火的手枪，贴近火药，扣动扳机，火药顿时燃烧起来。长木头上的那几只狼被火药烧伤了；有六、七只狼，由于火药的威力，也由于害怕火光，跌倒或跳进我们中间，我们立即把它们解决了。其他的狼也被火光吓住了，这时天色近乎漆黑，火光在黑夜里更加可怕，狼这才后退了几步。

For large capacity of inverter, due to the dc bus voltage is higher, ac output generally do not need to boost transformer can achieve 220V, in medium and small volume of inverter, due to the low voltage dc 12V, such as, must design, 24V pressor circuit.

对大容量的逆变器，由于直流母线电压较高，交流输出一般不需要变压器升压即能达到220V，在中、小容量的逆变器中，由于直流电压较低，如12V、24V，就必须设计升压电路。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
