岩芯柱样用静力岩芯采样器于1986年采自福建省厦门港一九龙江口海域。通过对这些岩芯柱样中六氯化苯(BHC)的垂直分布状况和生物扰动类型的分析,应用 S_R=D_(BHC-D_(mix)/Y的计算模式,获得了这些岩芯的现代沉积速率数据。将这些数据、方法与原理完全不同的~(210)Pb放射性同位素测年法同岩芯测年数据比较,其结果在数据和数量级上有一定可比性。初步认为,再经进一步探索和改进,BHC测年法有可能应用于近岸河口港湾几十年来现代沉积速率的测定而与其它测年法互为补充。 相似文献

In order to make up well a complete picture of storm surges in the area of theTaiwan Strait, to find out and further study the formation mechanism and regularity ofstorm surges of this strait, nonlinear numerical computations have been made on thestorm surges formed by typhoon which directly hit the area along three main tracks. Inaccordance with the current field of shallow-sea storm surges with the characteristics of"boundary layer" current field, the finite difference technique is adopted on the basis ofthe whole current equations of storm surges, and the anticipated results are obtained. 相似文献
