On the forepart of the vortex, the fluid rotates adown and changes the speed type of ground, the inflexion whose position falls continuously appears, the sweep appears, and the inflexion is below the sweep.

其前部向下旋转的流体会造成当地速度型改变，形成拐点并导致拐点位置不断下降，出现下掠运动现象，速度型的拐点在下掠运动的下方。

To do this, I move the camera back, up and looking down at an angle.

然后，我移动摄像机向后、上，并使它对准斜下方。

They share many similar or the same featutes with Archaeopteryx or other primitive birds, such as: U-shaped furcula, uncinate process, laterally facing glenoid of shoulder girdle, comparatively long forelimb, large semilunate carple, retroverted pubis, ascending process of astragalus, and "modern feathers"with rachis and barbs etc.

奔龙类是一类较为特殊的手盗龙类，它具有许多与始祖鸟Archaeopteryx甚至其它早期鸟类相似或接近的特征，主要表现在：叉骨U形与始祖鸟和孔子鸟类的相同，背肋钩状突在孔子鸟类和个别反鸟类中也存在，肩臼窝绝大部分指向侧方类似于始祖鸟，肩胛骨与乌喙骨间的夹角非常接近90°也和始祖鸟的相似，前肢从比例上讲显得较长，大的半月形腕骨使肘部能向侧方折过来，耻骨伸向后下方，距骨上升突与原始鸟类中的为同源结构，羽毛已有显著的分化且具备了现代羽毛的基本结构等等。

C. Eleate subperiosteally the flexor digitorum longus muscle distally and laterally and the popliteus muscle proximally and medially and expose the posterior surface of the proximal fourth of the tibia Fig.

将趾长屈肌牵向外下方，做骨膜下剥离，同法剥离腘肌并牵向内上方，即可显露胫骨近端1/4的后面(图1-37D)。

C. Elevate subperiosteally the flexor digitorum longus muscle distally and laterally and the popliteus muscle proximally and medially and expose the posterior surface of the proximal fourth of the tibia Fig.

将趾长屈肌牵向外下方，做骨膜下剥离，同法剥离腘肌并牵向内上方，即可显露胫骨近端1/4的后面(图1-37D)。

Retract the semitendinosus proximally and medially and the gastrocsoleus component distally and laterally; the popliteus and flexor digitorum longus muscles lie in the floor of the interal Fig.

将半腱肌牵向内上方，腓肠肌牵向外下方，在间隙底部可见腘肌和趾长屈肌(图1-37C)。

The markings should be located asfollows: a spot over each eye; on cheeks; as a strip around each sideof muzzle, but not on the bridge of the nose; on throat; triangularmark on both sides of prosternum;on forelegs from carpus downward tothe toes; on inside of rear legs showing down the front of the stifleand broadening out to front of rear legs from hock to toes, but notcompletely eliminating black from rear of pasterns; un-der tail; blackpenciling on toes.

斑纹出现在下列位置：两眼睛上方各有一个污点；面颊；口吻两侧有带状环绕，但不能出现在鼻梁上；喉咙；三角型斑纹出现在前胸两侧；前肢从腕部向下到脚趾；后腿内侧，向下到膝关节，并在飞节到脚趾位置扩展到腿前面。但后脚腕不完全排除黑色；尾巴下方；脚趾有黑色铅笔纹。

The winded portion around the bead core comprises an axially inwardly extending turnback part above the bead core, and a base part under the bead core.

所述绕每个胎圈芯的卷起部分包括一个轴向向内延伸、位于胎圈芯上方的折回部，以及一个位于胎圈芯下方的基部。

It can be seen from the results that: water potential in quartz sand layer decreases with increasing thickness of the quartz sand layer under fixed sprinkling rate and increases with increasing sprinkling rate under fixed thickness of quartz sand layer; some of water above quartz sand layer flows down through the quartz sand layer and some flows down along edges of the quartz sand layer; some of water detoured the quartz sand layer flows into the region below the quartz sand layer closely along lower surface of the quartz sand layer.

实验结果表明：在喷水强度一定情况下，石英砂层中的水势随石英砂层厚度的增加而减小；在石英砂层厚度一定情况下，石英砂层中的水势随喷水强度的增加而增大；石英砂层上方的水部分通过石英砂层向下流动，部分绕过石英砂层向下流动；绕过石英砂层的水部分地紧贴石英砂层下表面向石英砂层下方的黄土中流动。

Lock it by dropping the seatpost, then swing the front wheel under and round, and tuck it in next to the rear wheel, with the derailleur nestled between the front wheel spokes.

折叠前须将链条变到后飞轮最小齿，接著将后轮往前荡向主管下方，下滑座杆将之卡住；再来把前轮向车身收折至后轮旁，此时后变速器会恰好介於前后轮钢丝间；最后将立管放下折向另一边。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
