| 摘 要： | 一、14C年代测定单板机的功能1.数据处理 1)被测样品的在线数据处理 14C年代测量时间较长,一般一个样品要测够1000分钟,每10分钟为一段,测量到预置的时间后,单板机就用“3σ”作判据对各段计数进行统计检验,对偏离值超过“3σ”的数据可剔除掉,若要求测量时间一致,还可再补充新的测量值,经过剔除和补充后,将得到“σ1”值,再用“3σ1”作判据,重新进行统计检验,直至全部偏离值没有超过“3σn”为止。仪器及电网负载工作状态正常时,偏离值超过“3σn”的机率只有3‰,所以一般不需要剔除和补充。当测量结束时,打印机打出样品的平均计数率、标准误差、试验误

| Abstract: | Utilizing the ZSS sigle card compuler with a liquid scintillation counter the 14C dating can be controlled successfully in an automatic way. Its function includes the record of the counts, check of the errors, changing sample in a pre-set time, calculation of the 14C ages and printing out the dates. Because it has an effeclive function as well as a small volume and good economy it is suitable to set up in a general 14C laboratory to improve the operation condition. These advantages beat realistic significance for the automation of 14C measurement. |
