--- Disclosed are a process and plant for the recovery of water from humid air, in which at night cool humid air is passed through an adsorbent medium layer which adsorbs water from the air and in which, by day, air heated by solar energy up to a temperature which is above the ambient temperature is passed first through this layer to absorb water from the layer and then is cooled down so that the water condenses.

摘要---透露，是一个过程和植物为香港经济复苏的水从潮湿空气，在这种在夜间凉爽潮湿的空气是通过一吸附剂的介质层，其中吸附的水，从空中和在其中，由天，空气加热太阳能能源最多的温度是高于环境温度是通过第一，通过这层吸收水层，然后是冷却下来，使水凝结。

Till now, there has not three-dimensional computation of radiation in system with complex geometry and fulled of inhomegeneous, absorpting and emitting medium existed in our country also. The author carries on three-dimensional computation of radiation in vectored nozzle for the first time, which undoubtedly establishes certain basis in this field.

Use of filling materials can improve the performance of zinc anodes .standard filling materials are calcium sulphate plus bentonite which is able to absorb and then keep moisture to reduce the resistance around the anode.

厘米的介质。为了提高锌带阳极的使用性能，可采用填充料，标准的填充材料是硫酸钙加膨润土，用以吸收和保持水分，降低电阻。

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。
