第十六届全国稀土分析化学学术研讨会

Rare earth elements（REEs） have been widely used in metallurgical machinery, electronic information, petrochemical, energy and other fields due to their unique physical and chemical properties. The REEs with enhanced optical, electrical and magnetic properties can be used to prepare advanced materials, such as fluorescent, polishing, catalytic and permanent magnetic materials. The indispensible REEs in the advanced materials, despite with trace amount, are known as "industrial vitamins". The preparation of unitary REE with high purity is fundamental to the industry of new rare earth material. The unitary REE is separated by hydrometallurgical process from rare earth concentrate with more than ten kinds of rare earth elements. The continuous separation process is evaluated by REE distributions. At present, most of the REE distributions in factories are obtained via artificial sampling coupled with ICP OES. The detection lags behind the production, resulting in unstable qualities of products. In order to determine the distributions of REEs on line, a XOR-50 rare earth distribution on-line analytical equipment was developed based on ED-XRF. A on-line determination of REE in rare earth separation process was established. The excitation voltage, current and filter were optimized according to the characteristics of REEs. The influence of the salinity was corrected by mathematical technique. The absorption enhancement effect was calculated by fundamental parameter method. The results of on-line detection are consistent with ICP OES. The relative standard deviation（n=11） of the main REEs（w＞ 1%） is less than 0.6%. The equipment can carry out automatically from the extraction solution in 1 minute. The measurement intervals can be set by the operator. Combining on-line introduction of the rare earth material, simultaneous analysis of multi elements, rapid detection in 1 minute, on-line analysis with self-starting and real-time transmission of the results, the method meets the r

针对多区域互联电力系统分层分区调度的特点,将由上层控制中心管理的区域之间的联络线及其端节点定义为边界网络,从而构建区域变量之间存在重叠部分而区域之间不显含耦合约束的分散最优潮流模型。提出一种基于分布式内点法的多区域互联电力系统最优潮流分散式优化算法。首先,采用内点法将得到各区域的线性修正方程,从而可将其等价表示为各区域的二次规划模型。基于分层协调模式,信息在上层控制中心和各区域的本地控制中心之间进行交换,可实现二次规划模型的分散优化,且所交换的信息不涉及各个区域的私有数据。该算法在继承内点法二次收敛性优势的同时,其计算精度与集中式内点法的相当,且无需参数调整。以4个IEEE标准测试系统和一个6056节点实际系统作为测试系统,并与其它分散优化算法进行对比分析,检验新算法的有效性。
