主题：关于月球上拍星星 -- njyd

因为有的是阿婆骡项目发表的照片的数量，所以只能算阿婆骡项目的平均。

因为没有每个鱼行园拍的照片的数量，所以不能算每个鱼行园的平均。

由于阿婆骡发表的照片数量巨大，比如说阿波罗17出仓3次（共1324分钟）拍照1986张（平均每40秒一张够发表标准的照片），减半也将近一千哪！

Lundberg提到的保护板就是Arnold所指的“保护铅板”，因为都是保护胶卷的，阿婆骡照相机用的是传统胶片，而太阳辐射是可以曝光传统胶片的，这是阿婆骡照相机需要保护的原因。

请看：

Jan Lundberg ：Protective plates were added to the case and film magazine.

H. J. P. Arnold：The only thing that would protect the film from this damage would be a thick layer of lead around the camera casing, which according to Hasselblad was not used.

因为“Jan Lundberg was the Manager Of Space Projects at Hasselblad from 1966 to 1975 and responsible for the production and building of the Hasselblad 500 EL/70 cameras that were used on the Apollo Missions.”所以，“according to Hasselblad”就是“according to Jan Lundberg”
