障碍物检测是自主车、机器人导航以及汽车辅助驾驶研究中重要的研究课题。

Trilobite features a more powerful and rug-friendly vacuum; a sonar to detect obstacles, so it seldom actually makes contact with anything; and a position tracker, so it can return to its home base and plug itself in when it needs a charge.

三叶虫吸尘器的特点是功率更强，也较适合地毯使用；它用声纳来侦测障碍物，所以很少碰撞到任何东西；它还有一个方位追踪仪，因此在需要充电的时候，能够自行回到充电座充电。

The lens axicon is based on the use of the spherical aberration of the mirror surfaces,which is inexpensive and easy to manufacture into a element with large apertures as compared with diffractive axicons,refractive cone axicons,and earlier lens axicons with aspheric surfaces;the opaque disk can offer the Bessel beams with long non-diffracting distances,and the diameter of the central peak is adjusted by choosing the focal length of the collimating lens;the tunable fluidic conical lens is a new device for generating Bessel beams,which can obtain the Bessel beams with different parameters by varying the refractive indexes of the solution which is filled in the device.

双透镜轴棱锥法主要基于透镜球面像差的运用，与衍射轴棱锥、折射轴棱锥和早期的非球面轴棱锥相比，具有加工简单、便宜，易于制作大尺寸的特点；不透明障碍物法得到的贝塞尔光束具有很长的无衍射距离，其直径可通过选择不同焦距的准直透镜来得到调节；可调流体轴棱锥是一种产生贝塞尔光束的新型器件，它可以很容易地通过改变注入器件的液体的折射率来得到不同参量的贝塞尔光束。

When miners tunneled toward the gym, they used a cutting torch that accidentally ignited the barrier. Choking smoke filled the tunnel.

当矿工们挖通向健身房的地道时，他们用的挖掘火把不小心点燃了障碍物，呛人的烟雾弥漫了隧道。
