Lenticular galaxies fall somewhere in between elliptical and spiral galaxies Occasionally galaxies collide and interact.

透镜状星系位于椭圆星系和螺旋星系之间，偶尔星系之间会发生碰撞和相互作用。

This is made possible through something called a lenticular lens – a corrugated sheet in which each ridge is made up of a convex – or outward-curving – lens.

这是通过一种叫做柱状透镜的东西实现的，柱状透镜是一种波纹状的薄板，其每个凸起处都由凸透镜（即向外弯曲的透镜）组成。

Chu demonstrated the " invisibility" at the event, and he made his legs disappear directly with the help of a magical material called " lenticular grating" that allows light to be refracted regularly.

褚在活动现场演示了 " 隐形" ，他借助一种名为 “柱镜光栅”的神奇材料，让光线有规律地折射，直接让自己的双腿消失了。

When multiple of these lenticular sheets with different lens distributions are layered in just the right way, they are able to refract light at a myriad different angles to create " dead spots " .

将许多这种在不同位置配有透镜的柱状透镜以适当的方式分层堆放，就能折射出千千万万种光线角度，从而制造视觉" 死角" 。

Sometimes, this kind of turbulence is actually visible thanks to rotor clouds in the eddies and lenticular clouds over the tops of the mountains, but ideally, you know about it before you see it.

有时，这种湍流实际上是可见的， 这要归功于涡流中的旋翼云和山顶上空的荚状云，但理想情况下， 你在看到它之前就知道它了。
