单能射线谱形的数据采集和数据处理

The Single Energy Spectrum Data Collecting and Data Processing

这是一个研究型综合性实验。先讨论了γ闪烁谱仪线性的好坏,通过对仪器进行定标调整,得到摄谱仪在高电压、低放大系数下的线性好的结论。选取所测的一段谱形,根据光滑和寻峰的基本原理编制Pascal程序进行数据多次处理及打印,进行分析得到实验值与理论值接近的结论。由于采用了Pascal语言的绘图性能,既避免了曲线的失真不光滑,又可以得到任一幅谱形图,满足用户的需要,这是其最大的实用性。

The γ radioactivity spectrograph operation principle,structure and characteristic are introduced,and its property is studied.The problems in using and adjusting spectrograph are proposed,and their influence on the accurate measurement of γ-rays spectrum is discussed.In consideration of the γ radioactivity of various factors,dependable towards procedure,the proceed modification,can apply in handle,passing logarithms according to analysis of verity procedure.So it can be used to modulate the program to reduce distortion.
