In Vitro and In Vivo Characterization of Alpha-1A Selective Agonists and Their Utility for Stress Incontience
      
A new way to estimate the parameters in the progressive stress accelerated life testing
      
In this article a deficiency in the classical approach is pointed out and a new method for the statistical analysis of life data, especially for electronic products, under progressive stress (voltage)V(t) =Kt is given.
      
Using the Bayesian method, for certain choices of the prior distribution, several forms of estimators of the parameters in the normal stress Weibull distribution and the inverse power law model are derived.
      
In particular, when the new shape parameter of the distribution under progressive stress is given (or estimated in advance), the closed forms of these estimators are relatively simple and are numerically accessible on computers.

Residual stresses in coating-based systems, part I: Mechanisms and analytical modeling
      
The thermo-mechanical integrity of these systems is becoming a major concern and is strongly related to the residual stresses because of the fabrication processes.
      
In this paper, the sources of the residual stresses in the coating-based systems and the concept of "misfit strain" were briefly reviewed.
      
Analytical models were developed to predict the residual stresses in multi-layered film structures or coating-based systems using the force and moment balances.

Some essential relations among material properties and dimensions of the coating and substrate and the residual stress variations are reflected.
      
It is shown that the existing model adequately describes the observed character of internal stress variations near the indentations sites only in the absence of additional stresses related to the sample preparation technology.
      
During calm periods (July-September) of the wind stress variations, the sensible and latent heat capacity fluxes change considerably, mostly in the region between 137°-140°E, while to the east of 150°E, the heat capacity flux changes less.

前燃料工业部电业管理总局东北设计分局于1952—1953年曾设计了东北某地22万伏高压送电线路。在苏联专家维金尼科夫的指导下,由于设计分局和东北电业局同志们的努力.该线路于1954年1月27日胜利地全部建成。由于初次从事这项工作,设计部门缺乏经验,为了验证设计方法是否正确,铁塔工作是否可靠,特于1953年6月间进行了线路中为数最多的直线铁塔的真形实验。铁塔结构是参考苏联酒杯形铁塔型式进行设计的,高25.3公尺。由于该线路所在地区的地形对结构的要求,以及受当时施工条件的限制,因而采用螺栓结构,材料为钢3,四脚分别置于混凝土预制基础上。为了消除试验时基础可能产生位移而影响铁塔的试验结果起见,将基础特别加强。试验按照各种设计的受力情况进行,包括正常情况、事故情况及超荷情况;并将作用于导线及塔身的全部风力以当值风压代替,集中作用于横梁上。用经纬仪在塔的四面测定塔在受外荷作用时的挠曲情况,用千分表(因受当时设备条件的限制)测定主要构件的变形,再由变形推出构件中的应力大小。由于用千分表在高空观测构件的变形极为困难,同时实验前的准备工作亦不足,因而测定主要构件的应力极不准确,只能从塔身的变化结果来判...

萧振群同志在其“调整连续梁桁架内部应力之研究”一文中证明两跨连续梁最有利的应力调整的绳准是在离端支承x=0.707l处的最大正负弯矩相等。讨论者们通过简易的数学运算,推广解决多种超静定桥梁应力调整绳准点的位置: 对于三跨连续梁桥,边跨的绳准点的位置在距端支承x≈0.775l处,中跨的绳准点在各距支承x≈0.3l处; 对于多跨连续梁桥,中间各跨的绳准点的位置在距支承x≈0.25l处; 对于两铰拱,绳准点的位置在x≈0.3l处,其推力的最有利调整值为:H_o=M_++M_-/2y,式中M_+、M_-、y等为绳准点处的最大正核心弯矩、最大负核心弯矩、相对铰轴连线的座标; 对于无铰拱,绳准点的位置在x≈0.25l处。

Under the action of a twisting moment M_z(e.g. due to eccentric loading on the bridge fioor), the reaction of a bridge superstructure may be classified into two parts: the pure twisting moment M_k formed by the shear flow along the whole crossection of fhe superstructure(including the top and bottom lateral systems), and the bending—twisting moment M_(u.k)formed by the shearing forces in the maingirders(lateral systems not included)sustaining different bending moments. Pure twisting does not induce stresses...

Under the action of a twisting moment M_z(e.g. due to eccentric loading on the bridge fioor), the reaction of a bridge superstructure may be classified into two parts: the pure twisting moment M_k formed by the shear flow along the whole crossection of fhe superstructure(including the top and bottom lateral systems), and the bending—twisting moment M_(u.k)formed by the shearing forces in the maingirders(lateral systems not included)sustaining different bending moments. Pure twisting does not induce stresses in flangcs(or chord member) of mainginders, while bending-twisting does. To assure a bridge superstructure functioning in space as a whole, it is necessary to provide it with both top and bottom leateral system and to proportion the cross frames adquately. The relative magnitude of M_k and M_(u.k)is an index showing to what degree the space action of a bridge superstrecture as a whole has been developed. This ratio will depend upon the relative rigidity of crossframes(against shearing deformation)and maingirdes(against bending). Using simple method of theory of structure, the author derives practical formulas for computing two- or multi-girder bridges equipped with single or several crossframes.

在承受扭矩(例如由于桥面偏心荷载)M_z时,桥孔结构的作用可分为两部份:净扭作用M_k和弯扭作用M_(u.k)。净扭矩由桥孔结构整个截面(包括顶、底联结系)对扭转的抗力(剪力流)组成,并不在主梁弦杆成翼缘中引起应力。弯扭矩由各主梁(不包括顶、底面联结系)承受不同的弯矩而在各梁截面上发生相应的剪力组成,并对主梁弦杆(或翼缘)应力有直接影响。设置顶、底面联结系并适当地布置断面联结系是保证桥孔结构空间整体作用的必要条件。M_k 和M_(u.k) 的相对比值是桥孔结构空间整体作用发挥程度的指标。这个比值视断面联结系抗剪与主梁抗弯的相对刚度而定。本文利用结构力学的简单方法,导出了具有单片或数片断面联结系的双主梁或多主梁桥的实用计算公式。
