This enabled the carronade to be traversed in a limited arc, increasing its potential target area.

这可以让卡隆炮在有限的角度里转动，增加射击区域。

You often have to slide your mouse through two precise ninety-degree turns just to reach the second level of a cascading menu .

你经常需要把鼠标转动两个九十度，才能找到第二级菜单。

Beside, he invents the world's first automatic astronomical apparatus _ a water-powered celestial globe and makes the seismographs for detecting directions of the earthquake and observing meteorological phenomena. According to legends, he also makes other instruments such as compass cart and mileage cart.

创造了世界上第一架自动的天文仪器——流水转动的浑天仪，创造了测定地震方向的地动仪和观测气象的候风仪，还制造了当时只有在传说中有过的指南车和记里鼓车等。

Either of two galaxies orbiting the Milky Way; visible near the south celestial pole .

围绕银河系转动的两个星系之一；在南极附近看得见。

There are assumptions about aircraft's ground motion; one of those widely used is "the center of simultaneous turning of the airframe is the same as the center of curvature of the mass center's track".

对飞机的地面运动一直沿用瞬时转动中心等价于质心轨迹的曲率中心的假设。

The spin of the Earth causes the winds within the storm to whirl around the center of the low pressure.

地球的转动引起这些暴风雨中流动的空气围绕低气压的中心旋转。

At the center of the observation wheel: Rolling bearings from FAG which ensure the wheel rotates reliably.

在观察车轮中心：从FAG的滚动轴承的车轮转动，确保可靠。

Driven by the valve stem to close one to wind the rotatory central point while rotating,the spheroid to the third a bit more separately, relative valve central point at this moment,from the third orbit a bit one cam form partial another,enter valve flat make valve it keep sealing to shut off down wards .

由阀杆带动关闭件绕旋转中心点转动时，球体由另点移至第三点，此时相对阀门中心点，从另点的第三点轨迹为一凸轮状偏心，向下进入阀座使阀门关闭保持密封。

The results are as follow:(1) In static status, the velocity of jet flow shows a symmetry distribution through central axis of enclosure.

结果表明，腔体静止时，射流速度沿腔体中心轴对称分布，腔体中心轴上的速度最大，两侧流速逐渐减小，近壁处为零；腔体转动时，在哥氏力的作用下，射流中心发生偏转，流场相对于腔体中心轴不再对称分布，腔体中各点处的流速分布随角速度而变化，压电射流角速度传感器利用这一特性敏感角速度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
