单体同位素分析技术（CSIA）最普遍的应用是根据母体化合物的同位素分馏特征来推测转化机理和产物生成，但是，在特定反应条件下，需要通过反应产物的同位素信号推演前体物/母体化合物的同位素指纹，例如，干酪根热裂解生成的丙烷。丙烷分子内同位素分析技术（PSIA）可以追溯不同分子位置碳（端元碳及中间碳）的同位素组成，为研究丙烷的来源与生成提供新的证据（图1）。目前，相关研究工作尚未理解干酪根中不同前体物的分...
近日，地球观测组织秘书处来函，确认联合国教科文组织国际岩溶研究中心牵头申报的地球观测组织（GEO）试点项目“全球典型岩溶区观测（EO4KARST）”已通过2022年11月3日在加纳召开的第18届GEO大会审议。
首先从参数估计、精度评定和质量控制角度论证了在精密定位中随机模型的重要性；然后基于短基线单差观测模型，采用严密的方差分量估计方法计算了不同频率、不同卫星的相位和伪距观测值精度，任意频率之间的交叉相关性以及不同频率的相位和伪距观测值在不同时间间隔上的时间相关性；随后分析了随机模型对基线精度和整体检验统计量的影响。结果表明：北斗用户接收机数据精度都与高度角相关，建议采用高度角指数加权函数；北斗二号3个...
