| 中文摘要: |
| 在论述NaI(Tl)闪烁谱仪系统的基础上，对NaI(Tl)闪烁谱仪的谱漂移产生机理进行了理论分析，并在理论分析基础上从测量和稳谱的角度对引起谱漂移因素进行了分类，以利于获得稳谱的方法及减小谱仪谱漂移产生的技术途径，并提出了对于非线性谱漂移的稳谱方案。 |
| 英文摘要: |
| Theoretical research is conducted in this paper on the causes for the spectrum-drifting of the actual operation principle,based on discussion of NaI(Tl) scintillation spectrometer system.The factors that may be the causes for the spectrum-drifting are sorted out on the grounds of energy spectrum measurements and spectrum stabilization with the result of theoretical analysis referred, so as to achieve the theoretical method of spectrum stabilization and practical techniques approach of correcting the spectrum-drifting of NaI(Tl) scintillation spectrometer. The spectrum stabilization measure is indicated on non-linearity spectrum-drifting. |
