(AudioDev BD Measurement Parameter Handbook节译)

The Shape of simple lens surface is produced with methods, which are creating a curvature as a part of the surface of a sphere. This type of lens shape is called spherical.

简单透镜表面的形状可使用多种方法制成，使镜头曲面是球面的一部分。这种类型的透镜称为球面镜。

---------------------------

Key Words：

lens [摄] 镜头；透镜；[解剖] 晶状体复数形式lenses

lense：镜头 =lens

'curvature n,弯曲，[数] 曲率: 针对曲线上某个点的切线方向角对弧长的转动率，通过微分来定义，表明曲线偏离直线的程度。数学上表明曲线在某一点的弯曲程度的数值。曲率越大，表示曲线的弯曲程度越大。曲率的倒数就是曲率半径。

sphere n,球体；adj,球体的。

spherical 球面的，球状的
