添加复合粘结剂的球团试验

对复合粘结剂与无机膨润土粘结剂进行了球团对比试验。试验结果表明，复合粘结剂的成球性能远远优于无机膨润土的，可大幅度降低粘结剂配比(由2．5％降低至0．6％～1．0％)，提高球团矿品位(球团矿品位上升0．8％～1．0％)。配加复合粘结剂的生球爆裂温度和成品球强度指标均有下降，但这些指标都能满足球团生产和高炉冶炼要求。     

摆线轮齿形的组合修正方式及其优化设计

针对齿形已经确定的摆线轮,在修正方式及修正量未知的情况下,利用改进的复合形法对摆线轮齿形修正方式及修正量进行了优化分析．同时,采用工艺过程简单的“等距＋ 移距” 修正方式代替工艺过程较复杂的转角修正方式,使用该方法计算等距和移距修正量速度快,与传统的计算方法相比较,工作效率明显提高．计算结果表明：在摆线轮齿形的各种修正方式中,“正等距＋ 负移距”修正方式是较理想的摆线轮齿形修正方式．这种修正方式具有理想齿形,加工工艺简单,在设计与制造中有一定的推广使用价值

Pseudo-Stokes Vector Correlation From Complex Signal Representation of a Speckle Pattern and Its Applications to Micro-Displacement Measurement

Abstract:  As an improvement of the intensity correlation used widely in conventional electronic speckle photography, we propose a new technique for displacement measurement based on correlating Stokes-like parameters derivatives for transformed speckle patterns. The method is based on a Riesz transform of the intensity speckle pattern, which converts the original real-valued signal into a complex signal. In closest analogy to the polarisation of a vector wave, the Stokes-like vector constructed from the spatial derivative of the generated complex signal has been applied for correlation. Experimental results are presented that demonstrate the validity and advantage of the proposed pseudo-Stokes vector correlation technique over conventional intensity correlation technique.     

Binuclear aluminum complex as an efficient orange emitter in single-layer electroluminescent devices

A binuclear aluminum complex with a chelating anilido-imine conjugated Schiff base ligand, 1,4-{o-C₆H₄[N(2,6-ⁱPr₂C₆H₃)][CH  N]Al(CH₃)₂}₂C₆H₄ (3), was synthesized from the alkane elimination reaction of trimethylaluminum with the free ligand, 1,4-{o-C₆H₄[NH(2,6-ⁱPr₂C₆H₃)][CH  N]}₂C₆H₄ (2), at room temperature. The photophysical properties of complex 3 were briefly examined and it was found that complex 3 displays bright orange luminescence in solution and in solid state. Electroluminescent devices were fabricated by doping complex 3 in polymer blend host of poly(vinylcarbazole) and 2-tert-butylphenyl-5-biphenyl-1,3,4-oxadiazol using simple solution spin-coating technique. Efficient orange light emission was obtained from the fabricated single-layer organic light-emitting devices with a maximum current efficiency of 3.2 cd/A.
