露天矿排土场相似材料模型实验研究

为了对元宝山露天矿排土场边坡稳定性作出客观评价，采用相似材料模型实验的方法对排土场进行物理模拟。结果表明：随着排土工作线发展，荷载增加，测点的位移和应力变化特征为：应力趋向负值．出现拉应力，岩体在变形，并且容易破坏，同时位移明显增大。该结论为元宝山露天矿排士场下一步排土方案、边坡监测方案和边坡整治防滑措施的制定提供决策依据。     

纤维悬浮混合层中纤维取向与流场应力的研究

研究了纤维在混合层流场中的运动,流场用伪谱方法求解;纤维对流场的作用体现在流体方程的附加应力张量中.数值求解在流场作用下的纤维的运动方程,得到纤维的位置和取向分布.进行了纤维取向分布的实验研究,结果与计算定性符合.研究结果表明,当St数较小时,大部分纤维聚集在涡核内,并且基本呈水平或垂直分布;而大St数下,纤维聚集在涡核边缘,呈现不均匀分布,此时纤维取向受涡核边缘的流场支配,呈现包络涡核的特征.同时,由纤维导致的流场附加应力张量的最大值和最小值出现在涡核边缘,导致流场应力不均匀.     

量子跃迁几率的付里叶分析法

用付里叶变换分析法计算光与原子相互作用的跃迁几率，此法的优点在于把复杂的积分运算变成付氏变换的形式，并利用付氏变换的有关公式和定理方便地给出常见微扰的计算，具有一定的普适性、物理意义鲜明等特点。     

基于结构的神经网络模型

提出了一种基于结构的神经网络模型，并介绍了利用该模型进行系统建模与参数优化的方法，该神经网络模型本质上是结构化的，网络模型的结构与系统结构相对应，网络中神经元的个数是确定的，神经元之间的连接不是盲目的，而是根据子系统间的相互作用关系连接而成，网络的部分连接权值与系统结构参数相对应，具有明确的物理意义，所以，建模后可进一步进行结构参数的优化。     

猝冷骨架Ni催化剂的表征及不饱和有机官能团加氢行为研究

研究了采用猝冷法制备的Ni50Al50合金经碱溶液抽提铝后形成和多孔滑架Ni催化剂和催化行为，并与工业上广泛应用的Raney Ni催化剂进行了对比，用电感耦合等离子光谱（ICP）、X－射线衍射（XRD）、扫描电子显微镜（SEM）、比表面测定（BET）、X－射线光电子能谱（XPS）及氢吸附对催化剂进行了表征，活笥测试结果表明，猝冷合金催化剂（RQ Ni)对包括碳碳双键、硝基、羰基和腈青在内的不饱和有机官能团有较Raney Ni为高的加氢活性，这可以部分归结RQ Ni催化剂更大的活性比表积及两者由于制备方法不同而导致的结构差异。     

THE EFFECT OF ANION ON THE MORPHOLOGY OF ELECTRODE, THE ADSORPTION OF QUINOLINE AND THE SER SPECTRA

The effect of different anion on the morphology of electrode, the adsorption of quinoline and the SER spectra are investigeted. The adsorption peak of quinoline appears in cyclic voltammogram in Cl~- (or Br~-) -containing electrolyte, but not in NV_3~- solution. We also find that the adsorption of quinoline is correlated with Cl~- concentration. This indicates some complex consist of Cl~- and quinolne are produced on Ag surface, Scanning electron microscopy is used to evaluate differences in surface morphology subjected to ORC treatment in different anion solution.The surface morphology of Aq electrode roughened in NO_3~- solution on which no SER signal can be observed differs greatly from that of Ag electrode which roughened in Cl~-(or Br~-)-containing electrolyte.

This paper presents the SERS spectra of quinoline adsorbed on iron deposited on the silver electrode by the cathodic reaction of ferrousion. Adsorption and inhibition mechanism of quinoline were discussed by means of tire SERS spectra.     

THE EFFECT OF ANION ON THE MORPHOLOGY OF ELECTRODE, THE ADSORPTION OF QUINOLINE AND THE SER SPECTRA

The effect of different anion on the morphology of electrode,the adsorption of quinoline and the SER spectra are investigented.The adsortion peak of quinoline appears in cyclic voliammogram in Cl^-(or Br^-) -containing electrolyte,but not in NO3^- solution.We also find that the adsorption of quinoline is correlated with Cl^- concentration.This indicates some complex consity of Cl^- and quinolue are produced on Ag surface.Scanning electron microscopy is used to evaluute differences in surface morphology subjected to ORC treatment in different anion solution.The surjace morphology of Ag elecirode roughened in NO3^- solution on which no SER signal can be lbserved differs greatly from that of Ag electrode which roughened in Cl^-(or Br^-)-containing clectrolyte.
