双后

We took the double rear wheel drive robot as an object and mainly studied its movement structural model. The robot way recognition and the track simulation was completed with MATLAB.

以双后轮驱动机器人为对象，主要分析了其运动构造模型，并用MATLAB完成了对机器人途径识别和跟踪白勺仿真。

By varying the groove spacing, the diameter of the single or double diameter hole, and the rear air cavity depth and content, one can obtain absorption over a wide variety of frequencies.

通过改变槽间距，直径的单人或双人直径孔，与后方空气腔的深度和内容，就可以得到吸收超过各种各样的频率。

The stables have four-metre-high walls – double standard height – to allow plenty of room for fearful horses to rear up.

马厩有四米高的墙壁——双标准高度——以允许充足的空间用于养马。
