沉下

I remember you." Something flickers behind his eyes and his expression turns dark."

我记得你。&有什么东西在他眼前掠过，他的表情沉下了脸。&

Yes, that's it, heaven." He scowled."No, hell. I live in hell.

对了，天堂&他沉下脸：&不是，是地狱，我住在地狱。

The Auror scowls at him, but doesn't answer.

Auror朝他沉下了脸，但并没作答。

Arms out to the side, drop the elbow , drop the wrist, lift the fingers ,and drop the middle finger .

手臂向两侧伸开，手肘下沉，手腕下沉，手指翘起，并且沉下你的中指。

Th sun is dipping to the West -the sky is still bright but the inklings of nearing evening is creeping its way up.

太阳正在缓缓沉下西方，而天空则依然明亮，尽管黄昏的脚步正在细微移动着，蠕动着。

They were the voices of boys, hoarse and half grown and seized with terror, and now instantly I saw them: half a dozen black boys trapped neck-deep in a bog of quicksand, crying aloud for rescue as their arms waved frantically in the dim light and as they sank deeper and deeper into the mire.

现在一瞬间，我看明白他们了：那原是五六个黑孩子陷在沼泽的流沙中，深及颈部，当初他们愈来愈深地沉下到那泥淖中去时，他们在幽暗的夜色中，疯狂地舞动手臂，高声呼喊救命。

For the first time, a screw pile and pile driver system for preventing flood and rushing to deal with an emergency was manufactured. The screw piles of the system is different from screw drills used to sap, and it doesn't push soils out. Analyses, including the screw pile's structural strength analysis and the screw blade's welding analysis, were done by ANSYS, which showed that the screw pile's structural strength is enough and that the distort of the screw blade is small. Testing on the screw pile and pile driver system showed that the system performed stably and could meet the need of preventing flood and rushing to deal with an emergency. A mechanics model of interaction of a screw pile and soil was built, and expressions of torque of screw pile's cylindrical part on the condition of screw pile's crew part being driven into soil fully were gained, then the relation of the torque with screw pitch and out diameter of cylinder, which shows the torque decreases with the screw pitch increasing, and that the torque increases with the out diameter of cylinder increasing, which was according with the experiments of the screw pile's being driven into soils, and thus a screw pile with the best structure was chosen. Experiments of bionic surface showed that, on the condition of certain pressure on the surface, the protruding bionic surface can not reduce adhesion and resistance and that the corrugated bionic surface can reduce adhesion and resistance. An orthogonal experiment of the corrugated bionic surface was done with the factors including the width of protrusion, the space between two protrusions, the trolley's velocity and the vertical surface pressure and with the surface frictional coefficient as the experimental target, and some inclusions were drawn that the best combination of the factors was acquired and that the width of protrusion affected the surface frictional coefficient remarkably.

研制了防汛抢险螺旋桩机系统，提高了沉桩作业效率；利用ANSYS对桩体进行整体结构强度分析以及螺旋叶片的焊接分析，表明桩体结构强度足够，焊接过程中，螺旋叶片的变形小；对整个螺旋桩机系统进行试验，表明该系统性能可靠，工作稳定，作业效率高，能够满足防汛抢险沉桩作业基本需要；建立了螺旋桩桩土作用力学模型，得出螺旋桩沉桩过程中螺旋桩螺旋部分完全进入土体时螺旋桩圆柱部分所受扭矩以及扭矩与防汛抢险螺旋桩的螺旋导程和圆柱外径的关系曲线，表明螺旋桩螺旋部分完全进入土体时螺旋桩圆柱部分所受扭矩随着螺旋导程的增大而减小，随着圆柱外径的增大而增大，这与螺旋桩沉桩试验结论相符合，据此优选出最佳结构的螺旋桩；仿生曲面试验表明，尺寸较小的球冠突起型仿生曲面在一定压力作用下未能起到减粘降阻的作用，而尺寸较大的波纹型仿生曲面相对平板具有一定的减粘降阻作用；以波纹型仿生曲面突起宽度、波纹型仿生曲面两突起之间间距、台车的牵引速度以及叶片表面垂直载荷为因素，以曲面摩擦系数试验指标进行正交试验，寻求出在一定试验条件下最佳因素水平组合；波纹型仿生曲面突起宽度在本试验条件下对曲面摩擦系数影响显著，而其它几个因素对曲面摩擦系数影响均不显著；通过波纹型仿生曲面突起宽度和台车牵引速度的单因素试验，表明曲面摩擦系数随着仿生曲面突起宽度的增大而减小，而随着台车牵引速度的变化基本保持不变，和正交试验结果保持一致。

Guo Jiang plaints, now, hui Cong sinks idea take an examination ofing is most is how can better help business, help them find more business chance to make money, bring greater value for them.

郭江感叹道，现在，慧聪沉下心思考最多的就是如何能更好的帮助企业，帮他们找到更多商机挣到钱，为他们带来更大的价值。

Journey to the West to see older people's experience of suffering in the after taste of a cup of precipitation from heavy mellow wine, because they vicissitudes, to the heart to review their own AR traversed this path.

老年人看西游记者是在品尝苦难经历后沉淀下来的一杯醇美厚重的酒，因为他们饱经沧桑，要沉下心来回顾自己所走过的这条路。

But when you get right down to the nitty-gritty, you'll see that there is no better candidate to be a captain of the Golden State Warriors.

但是当你沉下心来看看事务的本质，你会发现在金州勇士队没有比他更适合做队长的人了。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
