盐沉积物

The profile distributions of silicate, phosphate and nitrate suggest that the organic material decomposition in area is mainly through nitrification during early diagenesis. Based on benthic fluxes of nutrients calculated using Fick's first law, benthic fluxes of silicate, phosphate and nitrate are -886.45~42.62 mol/(m^2d),-3.04~5.83 mol/(m^2d) and -189.43~21.05 mol-(m^2d), respectively, and perhaps silicate and nitrate are one of the major sources of nutrients for bottom water. Our results also reveal temporal and spatial variations of benthic fluxes for silicate, phosphate and nitrate, which may be related to sedimentation environment changes caused by global climatologic change.

在水－沉积物介面附近矽酸盐、磷酸盐和硝酸盐都存在著极陡的浓度梯度，Fick扩散定理的计算结果表明，研究区内矽酸盐、磷酸盐和硝酸盐的海底扩散通量分别为-886.45～42.62mol/、-3.04～5.83mol/和-189.43～21.05mol/，且矽酸盐和硝酸盐主要是从沉积物向底层水体扩散，是底层水体营养盐的来源之一；研究区内矽酸盐、磷酸盐和硝酸盐的海底扩散通量存在著一定的时间和空间变化，这可能与因全球气候变化而导致的沉积环境的改变有关。

The moderate halophile strain Nj223 was selected from Prydz Bay deep-sea sediment and identified by 16S rDNA as Halomonas sp.

This paper also shows the distribution of the fluorine in sediments of the area is mainly controlled by the chemical composition of the material from the surrounding islands, and the element seems to be incorporated by the hornblende at the most extent, thus the correlation between the element and the hornblende amount in the sediments can be expressed statistically as following: F=217+lnVh.

研究结果表明，测区沉积物中氟含量分布主要受周围岛屿风化基岩的化学成分制约；沉积物中主要含氟矿物：萤石/磷灰石、黄玉、黑云母等含量极低，氟在沉积物中赋存的矿物相主要与角闪石[AX_2Y_5Z_8O_(22)_2]有关。氟含量与碎屑矿物中角闪石的体积比间的关系式可大致表示为：氟含量=217+361nV_H；间隙水中的低氟主要由测区化学风化不发育及氟的钙盐沉积所致。

Results hPDLP wasisolated from human periodontium and most of the cells retained their fibroblastic spindle shape. hPDLP can be in-duced into osteoblast-like cells and adipocyte-like cells, and calcium deposition and lipid droplets were detected perspectively.

The sediment of flourish salt marsh was thinness than that of sparse salt marsh.

人类活动在改变盐沼植物特征的同时也会改变沉积物粒径的空间分异。

Alterniflora salt marsh presented a trend of increasing gradually from the upper to the lower region of the Yangtze Estuary. 21 species were identified. Assiminea sp., Notomastus latericeus, Cerithidea largillierl, Glauconome chinensi, Gammaridae sp.

2沿着长江河口纵向梯度，互花米草盐沼的大型底栖动物群落的物种数和多样性从上游到下游呈逐渐增多的趋势，丰度主要受到沉积物粒径和互花米草高度的影响。

Among them, the black rings puts in order salt crust sand content to increase, but the white rings puts in order by the silt and the clay primarily. The light and shade interaction annulus of salt crust granulometric composition difference are showed that the saline lake passed by evolutionary process, because of the climate and temperature changes in turns, which causing the saline lake deposit ingredients have regular change results.

其中，黑色纹理处盐壳含砂量增加，而白色纹理处以粉粒和粘粒为主，明暗相间的环带盐壳颗粒组成差异是盐湖向干盐湖的演化过程中，由于气候冷暖交替变化而使盐湖沉积物成分发生规律性变化的结果。

Contents of TOC, TN, and OP in Spartina alterniflora marshes are higher than those in other ecological zones.

植被对潮滩湿地中碳、氮、磷的分布有着重要影响，3种物质在互花米草、盐蒿和芦苇中的含量差别不是很大，因此潮滩植被对沉积物中上述3种物质的贡献差别主要是由不同植被的生物量和其所处环境的沉积动力差异造成的。

The tidal wetland sediment appeared the tendency of changing small from sea to land and from bottom to top.

结果表明，潮间带沉积物呈自海向陆和自下向上变细的趋势，一般光滩沉积物粒径〉50μm，盐沼上部沉积物粒径〈25μm；沿岸方向上，茂密盐沼的沉积物较之稀疏盐沼细；盐沼中的流速和波高较之相邻光滩减少50%以上；植物粘附悬沙干重达

The Martian rover Opportunity found lots of mineral salt deposits on the bottom of the Meridiani Planum, just south of the planet's equator.

火星漫游器&机遇&号在 Meridiani Planum 的底部发现了许多矿物盐沉积物，Meridiani Planum 刚好在火星赤道以南。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
