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.

The properties, reaction process and reaction dynamics of an inorganic zinc compound-CHUAN SHE 6-1 used as sulfide scavenger for drilling fluids are reviewed, and its efficiency in desulfuration and corrosion prevention evaluated. A comparative study of the scavenger with the iron sponge scavenger (a U. S. product) and MILGARD(also a U. S. product) is described. Field tests show that CHUAN SHE 6-1 reacts rapidly with H_2S and shows high efficiency in removing H_2S at low cost. It can rapidly reduce H_2S concentration...

The properties, reaction process and reaction dynamics of an inorganic zinc compound-CHUAN SHE 6-1 used as sulfide scavenger for drilling fluids are reviewed, and its efficiency in desulfuration and corrosion prevention evaluated. A comparative study of the scavenger with the iron sponge scavenger (a U. S. product) and MILGARD(also a U. S. product) is described. Field tests show that CHUAN SHE 6-1 reacts rapidly with H_2S and shows high efficiency in removing H_2S at low cost. It can rapidly reduce H_2S concentration in drilling fluids to a safe level, thereby preventing H_2S stress corrosion and weight loss of drilling tools and casings besides its hazardous effects on operating personnel.

本文介绍了一种无机锌盐化台物——川设6—1钻井液除硫剂,根据试验结果,论证了它对钻井液的除硫效率和对钻具的防腐效果;并与两种进口的钻井除硫剂进行了对比。现场试验结果表明:川设6—1除硫反应快、效率高、成本低,使钻井液中的硫化氢浓度很快降低到安全界限,从而防止了钻具和套管的硫化物应力腐蚀和失重腐蚀,大大延长了钻具的使用寿命,并避免了钻井操作人员的硫化氢危害。

Calculating with this equation is simpler and more convenient than by the Canadian equation.

本文从薄壁圆筒环向应力公式和由于加热而产生的纵向应力出发,结合广义的米赛斯屈服准则平面问题表达式,提出了选择长输管道壁厚的一种新方法(文中还列举了应用实例)。本法系加拿大公式的推广,但比其计算简捷,而且比运用美英公式更为安全。这是该法的最大特点。

各种参数对于埋地热输管线弯管中温度应力的影响应用了有限元法进行研究。根据计算结果,用图表表示了各种参数的影响。其中,最重要的参数为弯管曲率半径与弯管外径的比值;弯管角度和作用于管线上的侧向土壤压力。本文最后指出了降低埋地热输管线弯管中温度应力的有效方法。
