总的看该地区季风活动经历了不稳定期-增强-有所减弱但仍活跃-强盛-逐渐萎缩几个变化阶段，这一夏季风的变化规律与大气环流模型预测的结果相似。

Because all fossils of Archaeopteryx come from marine sediments, suggesting a coral-reef setting, Videler (2005) suggested that, like the Jesus Christ lizards ( Basiliscus spp.), Archaeopteryx and its ancestors were 'Jesus-Christ dinosaurs' running over water to escape from predators and travel between islands in the coral lagoons of central Europe 150 million years ago.

因为所有的始祖鸟化石的发现，来自海洋沉积物中，暗示珊瑚礁设置， videler （ 2005 ）建议，像耶稣蜥蜴（ basiliscus最高人民检察院），始祖鸟及其祖先耶稣-基督恐龙运行水逃避天敌和旅行之间的群岛，在珊瑚环礁湖的欧洲中部1.5亿年前。

RESULTS:In the Chenxiang Lubailu table,the identification of bismuthic salt positive result with dilute nitric acid instead of hydrochloric acid and the white precepitation formed in identification of magnesian was bismuth hydroxide sediments,it was easy and accurate to identify bismuthic salt by adding ascorbic acid.

结果：该片中的铋盐碘化钾鉴别反应，用稀硝酸代替盐酸做溶剂，呈正反应；镁盐氯化铵-磷酸氢二钠鉴别反应，加氨试液后，析出的白色沉淀不是Mg2，而是Bi3，该沉淀在氯化铵试液中不溶，干扰镁盐鉴别；铋盐含量测定项，用加抗坏血酸掩蔽剂的方法，排除Fe3+的干扰，使终点颜色稳定，易于准确判断。

Mictyris longicarpus, Arachnoides placenta and Branchiostoma belcheri are only distributed in the sandy sediments outside the bay and in outer bay...

咸水草是感潮河段咸淡水指标种。河蚬虽是淡水种，也分布在低盐河段。

A total of 614 sediment samples at an interval of about 1.5 m from all 5 sites of the Integrated Ocean Drilling Program Expedition 311 on Cascadia Margin, northwestern Pacific were analyzed using a Beckman Coulter LS230 Particle Analyzer. The grainsize data were then plotted against depth and compared with other potential proxies of gas hydrateoccurrence such as soupy/mousselike fabrics in sedimentary textures, gas hydrate concentration derived from LWD data using Archie's relation, IR core images and the recovered samples of gas hydratebearing sediments.

对取自IODP 311航次（东北太平洋Cascadia大陆边缘）所有5个站位、采样间距约为1.5 m的614件沉积物样品，利用Beckman Coulter LS230激光粒度仪进行了沉积物粒度分析，获得了沉积物粒度随深度变化特征，进而与水合物层位的替代指标进行了位置对比，这些指标包括特殊沉积构造（soupy和mousselike构造）、测井数据推算出来的水合物饱和度、岩芯红外图像和实际钻取的含水合物沉积物等。

This rock contained chalcedonic cement before it underwent diagenesis, a process where low temperatures and low pressures alter the content of sediments before they finally lithify, or turn into rock.

这块石头包含石髓的水泥之前，它经历了岩化作用，一个过程，那里的低温和低的压力，改变的内容，沉积物之前，他们终于岩化，或变成岩石。

Low magnetic susceptibility, low CaCO_3, low organic carbon concentration C_(org, low C/A (Chenopodiaceae/Artemisia) ratio, low Sr concentration and, hence, high Rb/Sr ratio in the lake sediments indicate a cold but moist climate during the global Little Ice Age in the Daihai area.

岱海地区小冰期最盛期是以高Rb/Sr比值、低磁化率、低CaCO_3、低C_、低C/A比和孢粉浓度的湖泊沉积为特征的，反映流域所经历的冷湿的气候环境。
