查询词典 arcs

According to the basic equations derived under the two assumptions by Harold Lauffer—(1) the energy head of every point of a vertical section remains constant,(2) the flow lines are concentric circular arcs,this paper qives a comprehensive deduction of curvature effect in the characteristics of free overflow of round-crested spillway.118 runs of experiments of three round-crested spillway models of different size have been conducted by the author.

本文根据劳弗尔氏在两项假定[(1)垂直测线上各点所含能量为常数，(2)流线呈同心圆弧]下所导得的基本公式，作了详细的补充引伸，得出圆顶壩自由溢流时各项水力特性中的曲率影响计算公式。作者曾进行了大、中、小三个圆顶壩模型的试验共118组，试验成果基本上和导得的计算公式相合致。文中并根据试验资料制定了一些经验公式，应用时可更简便。

Foot of the statue of Dr. Sun Yat-sen is the steeple bell, semilunar Place bell roof arcs, top of the tomb and the tomb of the hemispherical dome roof, as the first round bell pendulum slip. Place the tripod southern Taiwan (now the images of Dr. Sun Yat-sen) to the clock bell in New York, the "ting" is the ancient symbol of power. The clock is therefore with the whole "to arouse the people to build in" with the United States.

山下中山先生铜像是钟的尖顶，半月形广场是钟顶圆弧，而陵墓顶端墓室的半球形的穹隆顶，就像一颗溜圆的钟摆锤，广场南端的鼎台为大钟的钟纽，&鼎&在古代是权力的象征，因此整个大钟乃含&唤起民众，以建民国&之意。

In order to reduce the effects of the force model errors on the coordinate solution, an extended Kalman filter has been proposed with short-arcs consisting of only a few consecutive passes of satellite over the tracking station.

为尽量减小力学模型不精确在站坐标解中带入的误差，本文采用推广Kalman滤波归算仅由单站二次卫星接续通过的测距资料以估计测站坐标的方法。

Water jets magically shoot through the air in broad arcs and disappear, just as unexpectedly as they appeared – Jumping Jet systems are the attraction in leisure parks and amusement parks, in discotheques, at trade shows, exhibitions, and other events.

水流魔法似地以弧形射过空气然后消失不见，正如意想不到的出现一样—跳跃喷头装置在公园、舞厅、贸易会、博览会以及其他一些场合都成为吸引游人的景点。

The authors observed the existence of active and idle arcs on the driving pulley and suggested that under some operating conditions, it is plausible for the bands to contribute up to 40–45% of the total transmitted torque.

作者们观察到存在的活跃和懒惰的驱动滑轮和电弧的建议下，操作条件下，它是似是而非的乐队为40 - 45%的总传递扭矩。
