质量歧视效应 - Fundamental of laser 40ar / 39ar dating method : our laboratory has successfully set up the laser microprobe 40ar / 39ar geological dating method . our works include adjustment of the high - gain electron multiplier in mass spectrometer and correction of mass discrimination , adjustment of the laser , test for absorption ability of minerals to laser , designing and manufacturing high - vacuum sample chamber , sample preparation and irradiation , research on the variability of j values on the surface of rock chips , measuring atmospheric argon , determination and correction of blanks and ages , etc . the laser microprobe technique is particularly effective for some geological samples . it can be used , for example , for research of distribution of the components in extremely small samples that are very difficult to be separated and purified and those which contain excess argon
本文首先从常规~ ( 40 ) ar ~ ( 39 ) ar阶段升温定年实验室的改进入手，进而建立了激光~ ( 40 ) ar ~ ( 39 ) ar定年实验室，利用这两种先进同位素地质定年方法，结合其他手段，对青藏高原腹地和北缘的阿尔金断裂系多期地质事件进行了详细的同位素年代学研究：一、参照国际先进实验室的流程，对我们的常规~ ( 40 ) ar ~ ( 39 ) ar阶段升温实验室在样品的预处理、样品的照射条件和系统空白测量及校正等方面进行了改进，使之产出的同位素年代数据更可靠并为国际同行所承认。
