230Thxs corrected for decay and assuming a 238U/232Th ratio of R=0.5, sediment focussing factors assuming dry bulk density of 0.5g/cm**3, and 230Th normalized sediment fluxes.
经衰变校正且假设铀-238(²³⁸U)/钍-232(²³²Th)比值为R=0.5的过剩钍-230(230Th excess, ²³⁰Thxs)、以干容重0.5g/cm³为前提计算得到的沉积物聚焦因子,以及经钍-230(²³⁰Th)归一化的沉积物通量。
