This paper utilizes varied methods to determine the modern times direction of maximum principal stress in Baka oilfield, and makes use of hydraulic fracturing data to estimate size and distribution law for three direction principal stress, in order to try hard to reflect objectively and authentically in-situ stress conditions at present for Baka oilfield.

文章运用多种方法确定了巴喀油田现代最大主应力的方向，利用水力压裂资料估算了3个方向主应力的大小及分布规律，力图客观真实地反映出巴喀油田现今地应力的状况，并简单阐述了裂缝与古今地应力的关系及在不同开发时期的作用。

Resonance light scattering spectrum of cadmium- phenanthorline- bromophenol blue system has been studied. The effects of interference substances and optimization of procedure have been investigated. In the presence of Tris-HCl(pH=9.60),Cd2+ reacts with Phen to form the chelate cation, which further reacts with acid dye of BPB to form an ion-associated complex. Then, the complex molecules are accumulated to particles by virtue of hydrophobic forces and other molecular forces. This results in significant enhancement of RLS intensity, and the enhanced intensity of RLS at 638nm is proportional to the concentration of Cd~(2+).

研究了镉-邻菲罗啉-溴酚蓝体系在碱性条件下的共振光散射光谱特征，考察了体系的影响因素和最佳反应条件，研究表明，在pH=9.60的Tris-HCl介质中，镉与邻菲罗啉形成络阳离子，再与酸性染料溴酚蓝形成离子缔合配合物，在疏水力等分子间作用力下，缔合物分子聚集形成缔合微粒，溶液的共振散射光显著增强；在638nm处RLS增强程度与镉浓度成线性关系，线性范围为0-3.20mg/L，检出限为4.50ug/L。
