针对嫦娥二号γ谱的非线性谱漂特点，提出了一种基于能量对应的谱漂校正方法。选取了嫦娥二号γ谱线作为研究对象，进行谱漂校正实验。结果显示：该方法能够有效校正嫦娥二号γ谱的非线性漂移，使Fe峰和Mg/K峰的峰位漂移范围控制在±1道范围内。

英文摘要：

During the detection of Changb - 2 （ CE2 ） gamma - ray spectrometer, Changb - 2 （ CE2 ） gamma - ray spectrum drifted because of the change of temperature and so on. In order to solve the problem of Chang - 2 （CE2） gamma - ray nonlinear spectral drift, the method was proposed which was based on the theory that the energy of element characteristic peak is fixation. Algorithm for realization of the method was introduced in the paper. The calibration experiment was carried out which was based on CE2 gamma - ray spectrum. The results have shown that the method could reduce influence of spectrum drift effectively; the drift range of Fe and Mg/ K peak position was plus or minus 1 after calibration.
