风暴潮灾与月相

本文以实测资料为依据,统计分析了风暴潮灾、风暴潮、登陆台风、天文高潮等与月相的关系。统计资料表明,登陆台风和台风风暴潮发生在大(小)潮期的次数相对较多,略大于平均数,但它们与月相没有明显的因果关系,它们相对于月相的分布大致上是随机的,如果台风在天文大潮期间登陆,台风引起的暴潮与天文潮叠加后成灾的概率明显增大,但也不一定成灾;成了灾的,往往是风暴潮峰值适逢当日的天文高潮所致。     

黄、东海毗邻海域悬浮体与水团的对应关系及影响因素

对黄、东海毗邻海域由陆架到深海的悬浮体进行了大量加密取样,获得了较准确的结果。给出了悬浮体含量及其三维分布,确定它们与水团及其边界有良好的对应关系。并从物源、动力和成因等解释了这种对应,提出了水团对悬浮体研究的重要意义。研究表明黑潮次—中层混合爬升水及其混合水形成悬浮体含量最低值区,横亘在陆架与深海之间,形成阻隔含有大部分悬浮体的陆架中、下层水体向深海输送的洁净“水障”,台湾暖流北上的顶托也起类似作用,并分析了影响悬浮体含量的各种因素及有关机制。

黄、东海海域水团发育对底质沉积物分布的影响

通过对黄、东海海域底质沉积物中的细粒级粘土矿物组合特征和全粒级碳酸盐含量分析、对比上覆水团和悬浮体资料，探讨研究区水团发育消长对底质沉积物分布的影响作用。结果表明研究区可以划分为长江冲淡水影响的长江型物质沉积区；黄海水影响的黄河型物质沉积区和黑潮水以及东海次表层水影响的残留型物质沉积区。而水团发育消长可直接影响下伏底质的分布特征。黄河型物质沉积区与残留型物质沉积区的分界相应于黄海冷水向东南扩展与黑潮次中层混合水向陆架爬升互为消长的长期综合平衡位置，而黄海冷水向东南的扩展范围代表着黄河物质在陆架向东南扩展沉积的最大范围．     

Internal wave eigenmodes and their weak nonlinear resonant interaction in a nonlinearly stratified fluid—A preliminary theoretical and experimental study

A preliminary theoretical and experimental study was conducted on internal wave modes and their weak nonlinear resonant interaction in a nonlinearly stratified fluid. An asymptotical solution of the modes and a dispersion relation of internal waves in a stratified fluid with density profile similar to that in our experiment were obtained theoretically. The resonant-interaction mechanism to 2nd order approximation is also discussed. The resonant interaction of the 3rd and 4th mode internal waves excited by the unstable 1st mode wave is analyzed on the basis of data obtained by conductivity probes. The resonant-interaction condition, i.e., ,k ₁+k ₃+k ₄=0, is examined. It is shown that the resonant instability increases with pycnocline thickness and wave maker driving frequency.

The distribution and geological significance of carbazole compounds in Silurian paleo-pools of the Tarim Basin,Northwest China

The results presented in this paper indicated that the carbazole-type compounds have high thermal stability and also show stability in oxidation and bio-degradation. This kind of compounds still has high concentrations and a complete distribution in the analyzed dry asphalt samples, showing that they are particularly useful in the study of hydrocarbon migration of the paleo-pools. The difference in the contents of nitrogen compounds in the Silurian dry asphalts from the Awati, Tabei and Tazhong areas is attributed to the difference in the extent of oxidation and （or） bio-degradation for the areas; the Awati and Tabei areas underwent relatively strong oxidation and bio-degradation. During the first stage of hydrocarbon pool formation in the Silurian system in the Tazhong and Tabei areas of the Tarim Basin （at the end of the Silurian period） and at the second stage in the Awati area （in Permian）, the hydrocarbons experienced a long-distance migration.
