AES照相法具有长期储存大量光谱信息,进行多元素同时测定,易于背景扣除和校正元素干扰等优点,但传统的谱板测光和数据处理操作十分繁杂,其效率不但低且操作者易于疲劳。为适应地球化学探矿扫面快速测试的需要,我们研制了此计算机自动译谱系统,计算机译谱是利用电子计算机的各种功能与微光度计配合,代替人工来完成光谱译谱,评价质量以及打印报告等一系列复杂而繁琐的劳动,以达到提高效率,减轻劳动强度的目的。 相似文献

The Large High Altitude Air Shower Observatory(LHAASO) is a composite cosmic ray observatory consisting of three detector arrays: kilometer square array(KM2 A), which includes the electromagnetic detector array and muon detector array, water Cherenkov detector array(WCDA) and wide field-of-view Cherenkov telescope array(WFCTA). One of the main scientific objectives of LHAASO is to precisely measure the cosmic rays energy spectrum of individual components from 10~(14) eV to 10~(18) eV. The hybrid observation will be employed by the LHAASO experiment, in which the lateral and longitudinal distributions of extensive air shower can be observed simultaneously. Thus, many kinds of parameters can be used for primary nuclei identification. In this paper, high purity cosmic ray simulation samples of the light nuclei component are obtained using multi-variable analysis. The apertures of 1/4 LHAASO array for pure proton and mixed proton and helium(HHe) samples are 900 m~2 Sr and1800 m~2 Sr, respectively. Prospect of obtaining proton and HHe spectra from 100 TeV to 4 PeV is discussed. 相似文献
