The numerical results show that, after the hot intrusion reaches the cold wall, some accumulates in the cold top corner, since the cold boundary layer flow cannot entrain all of the hot intrusion.

结果表明：当热入侵流抵达腔体冷壁后，由于冷壁无法卷入所有的热入侵流，热入侵流在冷上角堆积并产生一个反向流动，在冷壁边界层附近形成一个顺时针涡，该涡在浮力效应驱动下可返回热壁，并在腔体的冷热壁之间形成了腔体尺度的流体振荡，即内重力波。

For supercooling directional solidification, ideal directional microstructure can be obtained only within the supercooling range 63～83K and 127～170K. These two supercooling ranges just corresponds to the supercooling for developed equiaxial dendrites in ordinary supercooling solidification.

6对于深过冷定向凝固来说，只有在63～83K的低过冷度范围和127～170K的中过冷度范围才能获得理想的定向生长组织，而这两个过冷度范围正好对应于深过冷熔体凝固组织为发达的等轴枝晶的过冷度范围，这种组织的相似性似乎与过冷度一样具有遗传性。

C or less of saturated compressed air into the dryer of the pre-cooling device, in the pre-cooling device in heat exchange with the ambient air, high temperature air pre-cooling fan part of the heat is taken away, after pre-cooling the compressed air into the to the pre-evaporator refrigeration system with secondary refrigerant vapor heat exchange, allowing the temperature dropped close to the refrigerant evaporation temperature, and flows through the pre-filter to remove large amount of liquid water, oil mist and dust.

小于等于80°C的饱和压缩空气进入干燥机的预冷器，在预冷器中与环境空气进行热交换，高温压缩空气的一部分热量被预冷风机带走，预冷后的压缩空气进入到制冷系统的前置蒸发器，与冷媒蒸气进行二次热交换，使本身温度降到接近于冷媒的蒸发温度，并流经前置过滤器除去大量的液态水，油雾和尘埃。

This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

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。
