An integrated simulation system for solar sail space-craft with individually controllable elements (SSICE) is investi-gated in this paper, including the modelling of power manage-ment, thermal control, attitude control, umbra prediction, and or-bit prediction subsystems. Considering the self-control and re-activity subsystems, an agent based method is applied to deve-lop the subsystem models. Each subsystem is an individual agent component, which manages itself autonomously and re-acts to the requirements from other agents. To reduce comput-ing burden on a specified computer and improve the suitability and flexibility of the integrated simulation system, a distributed framework is employed in the system by deploying agent com-ponents on different computers. The data transmission among agents is based on the transmission control protocol/Internet protocol (TCP/IP). A practical example of sun pointing is used to test the operating effect of the integrated system and the work-ing condition of subsystems. The simulation results verify that the integrated system has higher sun pointing accuracy, quicker dynamical response to variations of the lighting, attitude and temperature and fewer computing resources with effective and accurate subsystems. The integrated system proposed in this paper can be applied to solar sail design, operation, and mis-sion planning.

应用电感耦合等离子体质谱法(ICP-MS)分析化探样品中的痕量银,通常在标准模式下用干扰校正法或动能歧视模式进行测定.银的两个稳定同位素均受锆和铌的氧化物或氢氧化物的质谱干扰,对于干扰元素锆、铌含量较高而银含量低的样品,测定误差较大,需要将干扰元素与银分离.本方法采用硝酸、氢氟酸、高氯酸消解样品,浓盐酸复溶提取,加入磷酸使大部分溶出的干扰元素锆、铌转化为难溶的磷酸盐化合物,通过沉淀与待测元素银分离.ICP-MS测定时以103Rh为内标,用90 Zr16O+同质量数的同位素106pd间接校正91Zr16O+
