sedimentation

1.Through the bedding distribution statistical analysis, studies the palaeocurrent during sedimentation.

通过对层理分布统计分，研究了积时古水流方向。

2.The sedimentation analysis method was used for measuring the sand content of settleable solid in wastewater.

应用物理化学分中的降分法对污水水体内可固体中含砂率进行测定。

3.Re-sults The sedimentation rate and viscosity of CMC-Na were the best，the redispersibility of AlCl3was the best.

结果 羧甲基纤维素钠（CMC-Na）的降容积比和黏度最好，三氯化铝重新分最好。

4.Two percent of HPMC appeared to be a satisfying suspending agent by evaluating the sedimentation rate and the redispersion of racecadotril.

通过对其降体积比、再分性指标的考察,筛选了2%HPMC助悬剂,并从流变学、混悬液黏度及显微形态等方面对其稳定性进行了研究。

5.The total sedimentation was that rivers were branching and migrating frequently,and the sedimentary structures and fossil of ichnite were growing generally.

其总体积特征为:河道频繁分支与迁移,发育各种积构造及生物遗迹化石。

6.Dissolution is controlled by both sedimentation and tectonization, and the converted degree on reservoirs is closely related to sedimentary facies and the distance from unconformity interfaces.

溶解作用受积和构造作用的控制，其对储层的改造程度与积相带及距不整合面的距离密切相关。

7.Site soils in southern area of Jiangsu province belong to washland sediment or limnetic facies sediment.The components of sediment are very complex and process of sedimentation is in disorder.

苏南地区场地土主要为漫滩相、湖沼相或冲湖相新近积软弱土,结构松,积零乱,成分复杂,饱水可液化粉细砂层及粉土层较为发育,在地震或动荷载的作用下有可发生软土震陷或砂土液化。
