1平方厘米区域在1米的距离内产生的辐射量与4平方厘米区域在2米的距离内产生的辐射量相同?这样翻译对吗? |

| | 辐射量 | Explanation: 您的理解有点含糊。
距离(光源)1米处的1平方厘米(的面积所)通过的辐射量与距离(光源)2米处的4平方厘米(的面积所)通过的辐射量相同。
(假设想象一下你自己就是一个发光的点,离你1米处的1个平方厘米这个面积所产生的辐射量 和 离你2米处的4个平方厘米这个面积所产生的辐射量 是一样的。)
因为:
其他条件相同(相同光源,相同光照时间等)的情况下,在单位面积内,辐射源与“受辐射面的距离的平方”成反比(http://www.hudong.com/wiki/太阳辐射)
此外,是光源产生辐射,不是那个面积产生辐射。 |
