Concentrations and isotopic ratios of thorium and uranium in pelagic sediments

The predictable in situ production of 230Th from the decay of uranium in seawater, and its subsequent removal by scavenging onto falling particles, provides a valuable tool for...海水中铀衰变产生钍-230（230Th）的可预测原位生成过程，以及该核素随后通过吸附清除作用附着于沉降颗粒而被移除的过程，为……提供了极具价值的研究工具。
