  subcritical
The conditions of the coexistence of liquid-vapor phases in capillaries were found, and the values of the coefficient of isothermal compressibility were determined by the calculated supercritical and subcritical adsorption isotherms.
      
At the later stage, small subcritical bubbles disappear due to gas transfer to large supercritical bubbles; as a result, the number of bubbles in the virtually equilibrium (as to the dissolved gas) liquid decreases.

It is found that the rate of reversible creep is controlled by the transport of hydrogen gas through structural defects into incipient subcritical cracks formed upon the action of stresses.
      
(As a rule, fluid motion still takes place for subcritical values of the pressure gradient, but very slowly; on reaching the limiting value of the pressure gradient there is a marked acceleration of the filtration.

This paper presents the results of an experimental investigation of natural convection in air layer at various aspect ratios and angles. The Rayleigh number range covered is-from subcritical to 106; the range of the angles of inclination, measured from the horizontal is: 0 ≤φ≤90 deg. Based upon the analysis of physical model and experimental measurements several new experimental non-dimensional formulas are proposed:The influence of aspect ratio on heat transfer is discussed especially.

This paper presents the results of an experimental investigation of natural convection in air layer at various aspect ratios and angles. The Rayleigh number range covered is-from subcritical to 106; the range of the angles of inclination, measured from the horizontal is: 0 ≤φ≤90 deg. Based upon the analysis of physical model and experimental measurements several new experimental non-dimensional formulas are proposed:The influence of aspect ratio on heat transfer is discussed especially. It is found that the influences of aspect ratio on heat transfer in different ranges of aspect ratio are different. It is more important in the range of low aspect ratio. In this situation the non-dimensional formula must be presented as a function of (Ra·cosφ) and aspect ratio. The recommended relationships (12), (13), (14) and (15) can be used for design of solar collectors.

本文对倾斜角度φ=0°、15°、30°、45°、60°和90°的夹层内空气自由运动放热过程进行了实验研究。对国外在这方面的研究概况作了简要的评述。在对已有的几种主要经验公式进行分析的基础上,提出了综合实验数据的方法,从而得出了较精确的实用经验公式。这些公式可用于太阳能集热器的设计计算。 本文还结合过程机理的分析讨论了AR比值对夹层放热的影响。

The article describes the experimental investigations carried out on a lOOOt/h UP boiler operating at subcritical pressure regarding the replacement of the throttle control valves for the distributies of flow in the furnace water walls by throttle orifices. An analysis is given on the role of the throttle orifice in the adjustment of heat deviation and on the method of selecting the pressure drop of the orifice, and concrete examples of two UP boilers in the Wangting Power Plant are cited.
