我已经生成了一个pdf文件：https://www.dropbox.com/s/k8u9ruy6nv78tnd/Can_not_show_in_Adobe_Reader.pdf， 它的页面很宽 - 752.69英寸。它不能在Adobe Reader中显示 - 只有两个空白页面，但它可以在Chrome和FireFox浏览器中显示其默认的pdf查看器。
我想知道为什么它不能在Adobe Reader中显示。有人可以给我一些帮助吗？

查看http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/adobe_supplement_iso32000.pdf的附录C，因为它明确指出：
177. In PDF versions earlier than PDF 1.6, the size of the default user space unit is fixed at 1 / 72 inch. In
Acrobat viewers earlier than version 4.0, the minimum allowed page size is 72 by 72 units in default
user space (1 by 1 inch); the maximum is 3240 by 3240 units (45 by 45 inches). In Acrobat versions 5.0
and later, the minimum allowed page size is 3 by 3 units (approximately 0.04 by 0.04 inch); the
maximum is 14,400 by 14,400 units (200 by 200 inches).
Beginning with PDF 1.6, the size of the default user space unit may be set with the UserUnit entry of
the page dictionary. Acrobat 7.0 supports a maximum UserUnit value of 75,000, which gives a
maximum page dimension of 15,000,000 inches (14,400 * 75,000 * 1 / 72). The minimum UserUnit
value is 1.0 (the default).
