Turnout for a double Y-shaped, with turnout of the convergence of the two sides, to the bifurcation.

双开道岔为Y形，即与道岔相衔接的两股道向两侧分岔。

Moreover, scanning tunneling microscopy images of the SWCNT with atomic resolution show that it has a (10, 10) structure with a diameter of 1. 3nm and the current-voltage characteristics in quasi-radical direction reveal its metallic properties.

未经过超声的SWCNTs容易凝聚；观察到纳米管弯曲、分岔的现象，这是由于纳米管的六边形网络中引入五边形、七边形、八边形等缘故；得到（10，10）型SWCNT的原子像；测量了SWCNT的准径向I—V曲线，表现为金属性。

With the increase of vibration frequency, the variation process of Jacobi matrix eigenvalue was calculated. According to the position of eigenvalue crossing the unit circle in the complex plane, the stability of fixed point of the map was discussed and the route from periodic motion to chaos via period-doubling bifurcation was received.

以振动频率为控制参数，计算得到映射Jacobi矩阵特征值的变化曲线，根据其穿越复平面单位圆的位置，分析了映射不动点的稳定性，获得了碰撞运动通过典型的倍周期分岔通向混沌的过程。

The stability and bifurcation of a thin elastic rod under tension and twist are analyzed, and the results can be applied to determine the stability of a thin helical rod by use of the equivalent stiffness.

分析受拉扭弹性细杆的稳定性和分岔，且利用等效刚度概念将弹性杆的稳定性条件应用于对细长螺旋杆稳定性的判断。

Let hair to keep the state in the most pure Should be pruned at any time bifurcation hair tail, because the bifurcation of the hair tail light directly block.

随时都要修剪掉分叉的发尾，因为分岔的髮尾会直接阻挡光线。

Let hair to keep the state in the most pure Should be pruned at any time bifurcation hair tail, because the bifurcation of the hair tail light directly block.

随时都要修剪掉分叉的发尾，因为分岔的发尾会直接阻挡光线。

The nexu's broad face was split by a terrifying tooth-filled maw, and four eyes glinted from atop its spade-shaped head. Its wiry, supple muscles were visible beneath its fine coat, and sharp curving quills lined its spine. A naked, forked prehensile tail trailed it, aiding in balance, and its arms and legs terminated in large curved claws.

它宽阔的脸被一张充满牙齿的可怕大嘴撕裂开来，四个眼睛在它铲子状的头上闪闪发光，强韧、柔软灵活的肌肉在它美丽的皮毛下清晰可见，弧形的尖刺排列在脊椎上，后面还拖著光秃秃、分岔、适於抓握且有助平衡的尾巴，在四肢的末端有著大而弯曲的爪子。

According to successfully extracting and graphing of uranium anomalies, the self-center uranium anomalies and their close relationship with meandering stream systems have been observed. The uranium anomaly always develops in the distributary and turning place of meandering stream system, and is related with thin sand area (whose sand thickness and sand ratio are less than 30 meters and 40% respectively), thicker coal, fine lithology, but the highest value of uranium anomaly exists in middle sandstone.

通过对铀异常信息的成功提取及平面编图，发现延安组中铀异常呈一个又一个具有自我中心的单元出现，且与曲流河沉积体系的关系密切：通常发育于河道分岔或转弯处；普遍发育于薄砂带，一般砂体厚度在30m以下，含砂率小于40%；铀异常单元与厚煤层关系密切；主要赋存于粒度较细的岩性中，部分也富集于煤中，但铀异常最高值富集于中砂岩中。
