  shrink ratio
A smaller shrink ratio often leads to a smaller clock switching power, but a worse design performance.
      
However, with a small shrink ratio, it does not matter so much for the new bounding box to keep the original aspect ratio.
      
In Section 5.3 and 5.4 we show how we can trade off power for timing and vice versa by tuning the power ratio and shrink ratio.
      
We see that clock wire length and switching power generally decrease with the shrink ratio decreasing.
      


Based on analysing a large quantity of data obtained from in-situ observation and laboratory experiments, it is explored that the main causes offthe land subsidence in Shanghai are the cyclic variation of the ground water table. The reological properties of the 1st and 2nd compressible strata are discussed. The important contribution of the compression of the aqueou sand stratum to the land subsidence in Shanghai is mentioned.

Based on analysing a large quantity of data obtained from in-situ observation and laboratory experiments, it is explored that the main causes offthe land subsidence in Shanghai are the cyclic variation of the ground water table. The reological properties of the 1st and 2nd compressible strata are discussed. The important contribution of the compression of the aqueou sand stratum to the land subsidence in Shanghai is mentioned. In calculating the values of storage coefficient of various soil strata, the rule of rebound and settlement can be readily evaluated by norma-li zing the observed deformation of different soil strata according to the range of variation of the ground water table. The conception of the ratio between rebound and compression is used to study the characteristice of residual deformation of various soil strata in Shanghai.

本文在总结分析以往大量的野外实测资料和室内试验资料的基础上,阐明了地下水位的升降变化是导致上海地面沉降的主要原因。文中论证了第一、二压缩层的流变性质,并指出含水砂层的变形在上海地面沉降中的主要作用。通过对各土层单位变形量的分析,将各土层的实测变形量根据水位变幅予以规格化,以便判断各土层的回升与沉降情况,文中还运用了“胀缩比”的概念,分析了上海各土层的残余变形特征。

A mathematical model of freeze sinking of shafts under the first category of boundary conditions is expounded and a Criterion equation evolved . The model designing and test procedure, made according to the modelling principles of similarity theory, are discussed. In the course of dealing with model designing, test and data analysis, the paper also goes into the interrelation between the reduced scales of geometric dimensions, time histories and thermophysical parameters.

本文论述了第一类边界条件下竖井冻结过程的数学模型,建立了准则方程。阐述了按照相似理论的模化原理所进行的模型设计及试验过程。研讨了模型设计、试验及数据处理中有关几何缩比、时间缩比及热物性参数缩比间的相互关系等问题。 由于该项研究工作是在1960~1964年进行的,实为我国研究冻结过程的雏型试验,水平有限,仅供从事冻结凿井设计、科研、教学及施工人员参考。

Zhujiang Fanying, a proposed building group to be erected on Zhu-jiang River shore in Guanzhou, consists of seven high-rise buildings. The experimental investigation is aimed at determining the differences of pressure distributions, forces and moments on the main building between the isolated case and group case, under different wind angles. The torsion moment due to wind load on building is also discussed. A 1:100 scaled model has tested in the 8m×6m Large Low-Speed Wind Tunnel. It is shown that for the same...

Zhujiang Fanying, a proposed building group to be erected on Zhu-jiang River shore in Guanzhou, consists of seven high-rise buildings. The experimental investigation is aimed at determining the differences of pressure distributions, forces and moments on the main building between the isolated case and group case, under different wind angles. The torsion moment due to wind load on building is also discussed. A 1:100 scaled model has tested in the 8m×6m Large Low-Speed Wind Tunnel. It is shown that for the same wind speed and same wind angle the results of isolated case and group case are different, and forces on the building are obviously influenced by wind angles. Distinguished torsion response will occur when the direction of wind is out of perpendicular to the building surface, even for the symmetric structure.

本文主要研究不同迎风角下,建筑群体中的主楼和主楼单体的压力分布以及力和力矩的差异;对建筑物的风载扭矩问题,也进行了初步探讨。所模拟的对象是将建于广州市珠江岸边的七幢高层建筑物。试验是在中国气动力研究与发展中心低速所大型低速风洞中进行的,试验段为8米×6米,模型的几何缩比为1:100。试验结果表明:在风速和迎风角相同的情况下,群体与单体的试验结果是很不相同的;此外,迎风角的微小改变,对建筑物的受力情况影响很大,即使是对称结构,当风向与建筑物表面不垂直时,扭转效应也非常明显。
