Experimental study on hydraulic characteristics of underflow for energy dissipator with step-down floor

现对跌坎式底流消能工消力池内水流流态的演变进行了初步分析，随着入池能量的变化，消力池中会产生混合流、淹没混合流、淹没底流以及远驱底流流态。

All the patients with 8-11 mm height of residual bone in the posterior maxilla underwent sinus floor elevation and implant placement using osteotome without any bone grafts simultaneously.

患者均因上颌后牙种植区牙槽嵴顶至上颌窦底之间的剩余骨高度在8～11mm，无法植入足够长度的种植体，因而采用上颌窦底冲压法局部提升上颌窦底骨板及黏骨膜，提升幅度为2～5mm。

Their chief use for delight is in privateness and retiring;for ornament,is in discourse;and for ability,is in the judgment and disposition of business.

在娱乐上学问底主要的用处是幽居养静；在装饰上学问底用处是辞令；在长才上学问底用处是对于事物的判断和处理。

In order to analyze vertical bearing behavior of belled pier foundation, three groups of project examples of belled pier in different engineering geological conditions are chosen.

为分析扩底墩基础的竖向承载性状，本文选取了三组不同工程地质条件下的扩底墩基础工程实例，分别建立了扩底墩墩土接触三维非线性有限元数值模型，可以发现计算与实测结果基本吻合。

Yet, even in the Old Testament, if you listen to David's harp, you shall hear as many hearselike airs,as carols: and the pencil of the Holy Ghost hath laboured more, in describing the afflictions of Job, than the felicities of Solomon.

然而即在《旧约》之中，如谛听大卫底琴音，就一定可以听见与欢颂一般多的哀歌；并且圣灵的画笔在形容约伯底苦难上比在形容所罗门底幸福上致力得多了。

A preliminary study on substrate specificity of Lumbricus Bimastus nuclease DNase E degradation studies showed that there were differences in degradation rate of the DNase E to different substrates.

双胸蚓组织核酸酶底物特异性的研究通过DNase E在最适反应条件下对几种不同底物降解速率的研究表明DNase E降解底物存在差异性。

Bio-Ba/Ti, bio-Ba /Al were chosen as the sensitive markers to show the variation of the biogenic/terrigenous suspended particles in MNLS through the correlation analysis of 12 major elements of the suspended particles. Comparing with the overlain waters, the content of terrigenous particles in the BNL was increased significantly, but was lower than that in the surface sediment.

与上覆水体相比，近底雾状层内陆源组分显著增加，但较底质沉积物为低；生源组分则明显降低，但比底质沉积物为高，这一规律说明底质沉积物再悬浮对近底雾状层有显著的影响，表明Ba_/Ti和Ba_/Al值可以作为近底雾状层颗粒物的高精度示踪指标，其中Ba_/Al值尤为敏感。

A relative low lake level between 8660～6010 cal.yr BPwas reflected by the clayey silt sediment with the median size less than 25μam and the sandcontent less than 4%,and the Pediastrum concentration was normally low.Between 6010 and2250 cal.yr BP,the median size and sand content increased greatly,and the Pediastrumconcentration raised sharply,suggesting a relative low lake level.After 2250 cal.yr BP,boththe median size and the Pediastrum abundance abruptly declined,suggesting the lake returnedto high level and the climate changed to humid.

UG04孔硅藻记录重建的湖泊水位变化基本上支持孢粉重建的古植被和古气候：8660～7230 cal.yr BP硅藻组合以浮游类主导，浮游／底栖比达40以上，指示水位较高，气候略湿润；7230～2330 cal.yr BP浮游类硅藻丰度和浮游／底栖比降低，湖泊处于低水位，气候干旱；2330～930 cal.yr BP浮游类硅藻丰度和浮游／底栖比增加，湖泊水位升高，气候湿润。

Yet even in the Old Testament, if you listen to David's harp, you shall hear as many hearse-like airs as carols; and the pencil of the Holy Ghost hath labored more in de- scribing the afflictions of Job, than the felicities of Solomon.

然而即在《旧约》之中，如谛听大卫底琴音，就一定可以听见与欢颂一般多的哀歌；并且圣灵的画笔在形容约伯底苦难上比在形容所罗门底幸福上致力得多了。

And then, take a 样纸 of the above checks, you peel to the backing sheet paper and again check the backing sheet on crack, because crack sometimes is a very small, only separated from the backing sheet and paper before it can be found.

然后，取一段经过上述检查的样纸，剥于底纸再次检查一下面纸和底纸上是否有裂纹，因为裂纹有时是非常小的，只有分开底纸和面纸后才能发现。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
