无机盐和十二烷基磺酸钠对丙烯酰胺──烯丙基磺酸钠共聚物粘度的影响

测定了丙烯酰胺──烯丙基磺酸钠共聚物（ＰＡＳＡ）与无机盐和阴离子表面活性剂（ＡＳ）复配体系的粘度，结果表明，无机盐降低ＰＡＳＡ溶液的粘度，而在ＡＳ存在下却随ＡＳ浓度的升高溶液粘度升高．ＮａＣｌ和ＡＳ共存时，二者的共同作用，使溶液粘度呈下降趋势．

CRC－3裂化催化剂被无机钒酸盐中毒活性的考察

采用微反应活性测试（ＭＡＴ）装置，以正庚烷为原料在反应温度为５５０℃和液空速为１０ｈ－１下，考察了ＣＲＣ－３裂化催化剂活性随水蒸汽处理时间的变化规律．模拟工业流化催化裂化（ＦＣＣ）条件，制备了无机钒酸盐中毒的催化剂，进而对其活性进行考察．ＭＡＴ活性评价数据表明，用水蒸汽处理ＣＲＣ－３裂化催化剂１２ｈ以后，其活性趋于平衡；而使ＣＲＣ－３裂化催化剂中毒的无机钒酸盐中钒含量高达０．５％时，催化剂活性将发生明显的变化．     

Finding global minima with a new dynamical evolutionary algorithm

A new dynamical evolutionary algorithm (DEA) based on the theory of statistical mechanics is presented. This algorithm is very different from the traditional evolutionary algorithm and the two novel features are the unique of selecting strategy and the determination of individuals that are selected to crossover and mutate. We use DEA to solve a lot of global optimization problems that are nonlinear, multimodal and multidimensional and obtain satisfactory results.

浅埋煤层开采中的溃沙灾害研究

分析了浅埋煤层开采的水文条件和工程地质条件，得出了浅埋煤层发生渍沙灾害必须具备的4个条件；根据浅埋煤层中组合关键层的一些参数分析了老顶破断岩块的运动规律，判断了浅埋煤层开采中岩块是否发生回转失稳，探讨了岩块回转触矸后发生滑落失稳的可能性，计算了断裂岩块端角接触面高度，得出了满足裂隙滤沙的合理端角接触面高度；大柳塔1203工作面开采只发生了涌水而未溃沙，这和理论计算的结论基本一致．参8．     

Why the Afshar experiment does not refute complementarity

A modified version of Young's experiment by Shahriar Afshar demonstrates that, prior to what appears to be a “which-way” measurement, an interference pattern exists. Afshar has claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer's Transactional Interpretation easily accommodates the result. It is also shown that the Afshar experiment is analogous in key respects to a spin one-half particle prepared as “spin up along x”, subjected to a nondestructive confirmation of that preparation, and post-selected in a specific state of spin along z. The terminology “which-way” or “which-slit” is critiqued; it is argued that this usage by both Afshar and his critics is misleading and has contributed to confusion surrounding the interpretation of the experiment. Nevertheless, it is concluded that Bohr would have had no more problem accounting for the Afshar result than he would in accounting for the aforementioned pre- and post-selection spin experiment, in which the particle's preparation state is confirmed by a nondestructive measurement prior to post-selection. In addition, some new inferences about the interpretation of delayed choice experiments are drawn from the analysis.
