关于焦度的说法，以下不正确的是： Which of the following is not true about the power of focus？A.常用焦距 f 的倒数表示透镜的折射本领，称为焦度。 The reciprocal of the focal length f is often used to represent the refractive power of the lens, which is called the power of focus.#B.当焦距为f =1米时，则其焦度为1 屈光度。 When the focal length is f = 1 m, the power is 1 diopter.#C.在配戴眼镜时，焦度又常用度做单位，1屈光度等于100度。 When wearing glasses, the focal power is often used as a unit, 1 diopter is equal to 100 degrees.#D.焦度是指聚焦的程度，焦距越大，焦度也越大。 The focus refers to the degr
