| 摘 要： | 氢化物—无色散原子荧光光谱法测定黄铁矿及地球化学样品中微量碲，采用硝酸，盐酸，高氯酸分解样品，用浓盐酸将六价碲还原成四价碲，再用硼氢化钾继续还原使碲形成氢化物ＴｅＨ２，在ＡＦＳ１２０１Ｃ原子荧光光谱仪进行测定碲的检示限为０．１８μｇ／ｇ，精密度ＲＳＤ％为６．８％，该方法操作简便、快速、准确、费用低，可应用于大批量地球化学样品的分析。

| Abstract: | COOL(concurrent object oriented language) is a kind of highly efficient concurrent programming language. In this paper, a concurrent object model (concurrent C++,CCPP ) and its language are presented. In this model, all objects are concurrent, and they communicate through asynchronous message sending. Concurrent objects are synchronized using a wait when necessary policy, and the synchronization constrains among concurrent threads within an object are described by path expressions. CCPP is an extension of C++, implemented by a precompiler. CCPP allows sequential/concurrent code reuse. |
