吸风

Compared with ordinary suction or brattice suction, the suction controlled by rotary jet has the following advantages

与普通抽吸或普通风幕屏蔽抽吸相比，旋风屏蔽控制捕吸具有以下特点

Study must first be carried out on the basic theory, such as structure of brattice, controlling mechanism and flowing way of blast suction air, to form a special suction flow field which has a high suction ability and is easily controlled and adjusted.

从风幕的结构、控制机理和吹吸气流的流动规律等基本理论上找到突破口，使得这种特殊的抽吸流场能具有抽吸能力强、易于控制和调节的特性。

Experts have recognized that the problem can not be thoroughly solved unless traditional way of suction be given up, that is, substituting soft brattice or blast suction air for rigid apron, and extending suction entrance near harmful substance or surrounding it.

国内外有关专家已认识到，要彻底解决这个问题，必须放弃传统的抽吸方式，利用柔性的风幕或吹吸气流代替刚性的挡板或吸气罩，将吸口"沿伸"到有害物附近或干脆将其"罩住"。

The equations of the orbital parameters are used to calculate the evolution of the orbital parameters and amount of accreted matter to the Ba stars.The effect of the parameters on the contamination factor are dis cussed.

在此基础上计算了Ba星系统在星风吸积过程中吸积的物质量和轨道参量的变化，并讨论了影响Ba星污染因子的因素。

We set up the angular momentum conservation model of wind accretion of Ba stars, and then derive the change equations of the orbital elements. Finally, combining the heavy element nucleosynthesis of AGB stars, we creatively calculate the heavy-element overabundances of barium stars in a self-consistent manner adopting accreting and mixing on successive occasions.

我们建立了Ba星形成的星风吸积的角动量守恒模型，推导出其轨道根数的变化方程，并结合AGB星的重元素核合成，通过逐次脉冲吸积与混合，自洽地计算出Ba星的重元素超丰。

Thus, in some countries, the rise of a wave in the palace nobility suction Wen snuff the wind, and even the Princess were also hiding in the palace secretly smoke smell snuff, and the princes were often put to the wine quaffed snuff.

于是，在一些国家王宫贵族中兴起了一股吸闻鼻烟风，就连公主们也躲在宫殿里偷偷吸闻鼻烟，王子们则常把鼻烟到在葡萄酒中一饮而尽。

This equipment is the use compressed-air driven principle, will heat up the hot air stream feeds in by the supersonic speed spurts the wind box, draws the lining, and rubs in the acceleration the lining, the lining when is spouted the air hose loses the pressure to enable the lining to puff.

本设备是利用风动的原理，将加温的热气流以超音速的速度送进喷风盒，吸进面料，并在加速度中将面料加以揉搓，面料在被喷出风管时失压使面料得以膨化。

If a variable-length is not fatal, can increase the vacuum printer still attracts; but in the case of variable-length very serious to the detriment of breathe in, you can use the appropriate uniform blowing up hair drier, sulfuric acid paper contraction, attracts, can't really back output and imposition.

如果变长不严轻，可不合调不小晒版机的真空度，仍能吸陡；但如变长很严轻而感化呼气时，可用电呼风不合陡均呼一下，硫酸纸关上，不即能吸陡了，的确不动，不即只好轻新输不入、拆版。

The results show that the rotary air curtain exhaust hood can effectively control the deleterious materials,greatly improve the suction.Therefore,it realizes long-distance trapping and low velocity emission of deleter...

结果表明：旋转射流屏蔽作用下的抽吸流场具有中部压力较低和提高抽吸能力的作用；新型旋风气幕式排风罩不仅能有效地控制有害物扩散，而且可以实现远距离捕集有害物及以较小的排风速度排放有害物。

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。
