多目标模糊决策在软土地基加固方案中的应用

针对软土地基加固方案的影响因素具有模糊性这一特点,运用模糊数学理论,对定性指标量化,利用层次分析法确定评价因素的权重,提出采用模糊综合评价法对加固方案选优,并结合实例进行验证分析。

预应力混凝土路面应力分析新思路

文中提出用有限元一无界元的方法计算预应力混凝土路面的应力和变形。针对预应力混凝土路面结构的特点，采用板底摩阻力的迭代处理模型和多向影射无界元，计算结果表明分析模型是正确的。采用的计算方法具有结点数目少、精度高、便于网格自动形成等特点。     

Isolation and Characterization of Microorganisms for Degradation of Minimal Oils and Fats at Low Temperatures

The isolation of microorganisms for biodegradation of minimal fats and oils at low temperatures was reported. By using rapeseed oil as a sole carbon source, six strains were isolated from five kinds of oils/fats-contaminated wastewater, soil, and active sludge. Among them, two strains which show the highest oil removal ratios were identified as Pseudomonas pseudoalcaligenes and Pseudornonas mendocina, respectively. The experiments of orthogonal impact conditions show that the optimal oil degradation condition is at pH 8.0, 5 C and 100 mg/L oil. Under this condition, the rapeseed oil degradation ratios of two strains after 24 hours amount to 92. 6% and 92.0% respectively, whereas the removal ratios of lard decrease to 39.5% and 54.3%.
