In order to justify the efficiency during the water elutriation process of separating ceramic inclusions from FGH95 alloy powder, the maximum theoretical and experimental size of FGH95 powder elutriated was compared at different water flowing velocity.

摘 要：通过对水淘析法的原理分析，运用流体力学中的摩擦数群法确定了以陶瓷夹杂物在水中的沉降速度来确定水流速度，及在确定的水流速度下，所能淘析出的FGH95合金粉末的最大尺寸；并以比较淘析出的FGH95合金粉末的实际最大尺寸与理论最大尺寸，考察了水淘析法分离FGH95合金粉末中的陶瓷夹杂的有效性。

The floc formed has better sedimentation property, and easily be separated from water.

并且产生的絮状物沉降性能好，容易从水中分离出来。

The flocculation reaction could be evidently devided into two stages:the flocculation of leaf protein and the precipi-tation of flocculate.

利用乳酸发酵酸作叶蛋白的沉淀剂，其聚沉反应可明显分为叶蛋白聚凝和聚凝物沉降两个阶段。

Tectonic subsidence and deposition sedimentation were primarily controlled by basin border normal faults. Uplift of basement rocks of the footwall was due to the tilting of border faults and became main provenance areas.

盆地构造沉降和沉积充填过程主要受边界正断层的控制，断层下盘基底岩石的抬升与盆地边界正断层活动相关，从而成为盆地主要的物源区。

This study focuses on the palynology and sequence stratigraphy of the Paleogene successions in the Jiyang Depression.

在陆相盆地中，基底沉降、沉积物供给和气候控制着基准面变化和层序发育，而气候的变化造成植被的变化，即造成了植被所产生的孢粉组合的变化，层序地层与孢粉组合有着密切的联系。

The rate of subsidence has been decreasing from area near vertex of delta to the coastal zone and some place is even rising, particularly in the early formed area. What is the different in the coastal is that the rate of subsidence is still high and can sustain a long time. This is because the land subsidence in the delta is mainly caused by the consolidation of sediments if there is no human activity. Especially in the newly formed area, Qingshuigou sub-delta, the rate of subsidence was more than 50 mm/a in the begining and now is still higher than 10 mm/a. When the newly sediments discharged by the Yellow River landed on the subaquatic delta, its load can drive the concolidation of the silt, which is on the surface of the Bohai seafloor. The rate of consolidation of the silt will be decreasing quickly in the first years, but still a long time in the later time with a slow rate.

研究结果表明：现代黄河三角洲在以宁海为顶点的河口扇形区域，近期均经历了不同程度的地表下沉过程，但是随区域地理位置和时间的不同，地表变化空间差异性比较明显；三角洲顶点附近区域的下沉速率自上世纪末开始逐渐减小，后期甚至出现轻微的抬升；滨海沿岸附近地区的地表形变特征相对比较复杂，各期叶瓣相互叠置及其各类沉积物的不均匀分配，使由沉积物自然固结压实引起的地表形变具有显著的空间差异；目前，除清水沟流路叶瓣表现为快速沉降以外，其它滨海沿岸区基本上都表现为微弱的下沉。

In the Bayer Process,production of alumina is limited by the rate of liquor passing through Kelly Presses.

拜耳法氧化铝生产中，溶出矿浆经重力分离沉降槽液固分离后，溢流溶液中仍然含有一定的浮游物杂质，在分解之前，需要对溢流进行二次净化，以脱除其中的浮游物。

It is caused by the differential settlement between bridge abutment and subgrade. As a result, it badly affects comfort of traveling, reduces velocity of steering, minishes capacity of highway, enhances the damage to vehicles and bridge abutment, and even gives birth to traffic accident.

桥头跳车是由桥台构造物与台背路基之间的不均匀沉降引起的，它的存在严重影响了行车的舒适性，降低了车辆的行驶速度和道路的通行能力，加剧了车辆及桥台构造物的损坏，甚至导致交通事故的发生。

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。
