Crystal structure determining of 7-ADCA based on X-ray powder diffraction

Traditionally, crystal structure data can be collected and determined from single-crystal X-ray diffraction. However, in the fields of organic and macromolecular crystallography, it is often difficult or impractical to grow single crystals with suitable sizes and purity. Therefore, it will be benefited from the newly growing analytical tool that combining X-ray powder diffraction based on polycrystalline samples and ab initio calcula- tion[1]. 7-ADCA is one of the most important intermediate…

矿井瓦斯涌出量时间序列的分形特性分析

应用分形论中的R/S分析法对矿井瓦斯涌出时间序列进行分析。计算了时间序列的赫斯特指数、概率分布分形维数和轨迹分维数。讨论了它们在矿井瓦斯涌出预测中的指导意义。计算结果表明正常情况下矿井瓦斯涌出量的变化趋势具有很好的持久相关性，可以用分形论对其作出趋势预测；而发生火灾时，持久相关性不明显。但两种状态下的概率密度分布都满足分形分布；时间序列轨迹都具有明显的分形特性。     

基于事件响应event-response的动态工作流系统

提出了一种在企业工作流管理系统中运用由协作的各企业提供的对事件的响应(event-response)的方案来实现动态的工作流系统。通过工作流引擎灵活地调度、控制，利用基于约束的动态绑定机制动态地将事件的响应请求绑定到合适的event-response和响应提供者(provider)，从而柔性地，协同地完成共同的目标。

Experimental Study and Numerical Simulation of the Casting-Forging Complex Near Net Forming of Alternator Claw-pole

As a newly developed precision technology, casting-forging complex near net forming process is utilized to produce complex components with a short lead time, low cost and high precision, thus to accelerate the response speed of the market and enhance the competitive power of products. In this paper, the casting-forging complex near net forming process of alternator claw pole was developed and investigated with a combination of experimental and numerical simulation method. Qualified near net workpiece was manufactured, mechanical parameter and relative field information during the forming process was also obtained. While the alternator claw-pole is processed with this technology, the forming force is small, the process is short and the quality of forgings is perfect. Therefore, the complex casting-forging near net forming process of claw-pole is an energy and material saving technology, which will have a vast developing and application prospect in the future.
