Almost all foregone experimental investigations have demonstrated that the vapor quality, x, and reduced pressure, Pred, play substantial roles in controlling the condensation FPD. This fact is also affirmed by the Spearman's correlation coefficient. Therefore, these factors should be considered as the...
This is an inflatable cushion or mattress that is both easy to inflate and deflate by means of a large re-sealable opening. This opening is protected from bursting open due to the increased pressure caused, for example, by a large body lying upon the mattress. The means of protection is ...
Researcher Dr Dimitris Ballas, a senior lecturer in Geography from the University of Sheffield, said factors such as social cohesion seemed to be more important than location. "One of the advantages of ourmethod is that it takes into account both people and places. For instance, with unemploymen...
In a word, the changes in ET have happened on various spatio-temporal scales during the past several decades but are mainly characterized by evident spatial differences. However, our knowledge of the main factors controlling changes in ET and even the relevant physical mechanisms are still ...
The flow structure around surface-mounted obstacles depends on a number of factors, among others, the height of each object, and the aspect ratio of buildings AR and G are the most determinative ones. The heights of the upstream and downstream objects were H1=1.2D and H2=2D, respectively,...
摘要：1. Compressed air system with two circuits having different pressures, with a utilisation device that can be acted upon by the circuit having the higher pressure by way of a first controllable valve device, especially for a pneumatic suspension system or a compressed air brake system in a...
A项太片面;文章没有提到最好的方法,排除B;D项不够具体;根据第二段“One showed that adults are much more cooperative if they work in a system based on rewards.”和第六段“of the younger children who were not spanked were five points higher than those who were”可知,研究表明,奖励能够促进合作...
Typically, an elastic analysis is carried out where load factors are applied to the materials to portray dynamic enhancement [2]. However, this kind of analysis does not consider the dynamic effects such as strain rate, inertia, and local failure, and therefore is not substantially apt for ...
Production pressure is higher for a two-phase system of air-water with respect to that of a single-phase system. Also, as the quantity of the injected gas increases, production pressure increases. • Increasing the mass flow rate increases the production temperature. There is an optimum mass...
