At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

经过两年多的实测和计算，根据传热学、流体力学、统计学等学科的基础理论，对大量数据进行整理归类、分析讨论，主要得到如下结论：(1)冬季，含有特朗贝墙体的被动式太阳房室内热湿环境较舒适性标准偏低，但人体感觉比较舒适，特朗贝墙体形成的热循环通风在调节室内温度和相对湿度方面起到很大的作用；(2)特朗贝墙体空气间层自然对流可以看作是两个等温独立大平板的自然对流换热过程的叠加，通过与大平板自然对流理论类比获得了计算热循环过程中对流换热量的经验公式；(3)特朗贝墙体通风口的启闭可以根据玻璃幕墙内壁面温度、蓄热墙体外壁面温度和空气间层进出口空气温度之间的关系来进行控制，从而有效地阻挡冬季冷循环的发生；(4)夏季，如没有有效的通风降温措施，被动式太阳房内会产生明显的过热。

Cooper Turbocompressor's Turbo Air 2000 Oil-Free Centrifugal air compressor delivers more CFM per horsepower than any other oil-free centrifugal or screw air compressor in the 150 to 350 horsepower range.

库珀透平涡轮空气2000无油离心式空气压缩机多cfm每马力，比任何其他无油离心式或螺杆空气压缩机在150至350马力的射程。

The results show that wet air reduces both fatigue life and strength with the influence-factor of 0.6059 and 0.8722, respectively. Wet air environment enlarges the dispersivity of fatigue life, therefore using the corrosion-influence-factor obtained by eigenvalue or mean value to predict the fatigue life with high reliability will cause an unconservative conclusion.

结果表明，潮湿空气环境显著降低了2024-T3铝合金的疲劳性能，潮湿空气环境对其疲劳寿命特征值和疲劳强度均值的影响系数分别为0.6059和0.8722；在潮湿空气环境中疲劳寿命的分散性变大，用疲劳寿命的中值或特征值得到的腐蚀影响系数进行可靠度95%的腐蚀环境下的寿命修正，将得到偏危险的结果。

The geometry of the air spaces and fixed resonance chambers is "streamlined"; there is only one set of functional vocal cords; the vocal cords are mounted in the air tunnel in such a way that, when adducted, they can produce sound only on expiration, instead of allowing both inspiratory and expiratory voice; and the epiglottis has moved so far below the pharynx as to allow the air from the larynx to stream freely through both nasal and oral cavities.

空气空间的几合学及固定共鸣室是流线型的；只有一组实用的声带；声带以这样的方式（当合陇时，他们只能在吐气时产生声音，而不是允许吸气及吐气声音）镶嵌在空气的通道上；且会厌到现在已移到咽头下方让从喉头来的空气自由地流动通过鼻腔及口腔。

--- 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。
