That region of the plate is quite small and so the cone of diffracted rays, for the most part, misses it . 相板上的这一区域是很小的，因此衍射光线锥的绝大部分不通过它。
It is found experimentally that the eye behaves as though the "outputs" of the three types of cones are additive . 实验发现，人眼具有把三种锥状细胞的“输出”相加的特性。
I've been screwing gimlets into his head, and sticking forks in his eyes, and cutting my name on him . 我把螺丝锥钉在他的头上，把木叉刺在他的眼睛里，把我的姓名刻在他的身上。
The oil-immersion objectives just described admit a wider cone of rays than a dry objective of the same diameter would . 刚才描述的油浸物镜与直径相同的干物镜相比，可容纳更宽的光线锥。
This setup, known as a conoscope, is shown in figure 14. 2 and consists of two stress-free plano-convex lenses a and b . 此装置称为锥光镜，如图142所示，它由A和B两个无应力平凸透镜组成。
Benefit of this modified shape is that the expansion around the first corner reduces the initial pressure coefficient on the frustum to low values . 这个改进的外型的优点是绕第一角点的膨胀会把截锥上的初始压力系数减少到很低的值。
This setup, known as a conoscope, is shown in figure 14. 2 and consists of two stress-free plane-convex lenses a and b and a diaphragm c having a small aperture . 此装置称为锥光镜，如图142所示，它由A和B两个无应力平凸透镜和一个带小孔的光阑C组成。
He was a cold flame of a man, small as koho, and as dried up, with a mahogany complexion and small expression less blue eyes that were more like gimlet-points . 他是冷若冰霜的人，象科霍一样矮小干瘪，皮肤呈赤褐色，一对毫无热情的蓝色小眼睛酷似两只锐利的锥尖。
