《国富论》第五章中,关于英国1磅重的金块能铸成多少价值的银币的计算。原文是
“In the English mint, a pound weight of gold is coined into forty-four guineas and a half, which at one-and-twenty shillings the guinea, is equal to forty-six pounds fourteen shillings and six pence. An ounce of such gold coin, therefore, is worth £ 3:17:10½ in silver.”
王亚南先生的译文:
“英国造币厂以金一磅铸成四十四个半几尼[guinea],按一几尼为二十一先令[shilling]计算,就等于四十六镑[pound]十四先令[shilling]六便士[pence]。所以,重一盎斯[ounce]的金币,等于银币三镑十七先令十便士半。”
这里的换算关系我给出,
重量[我自己查的,不知是否正确]:1 pound=16 ounce
币值:1 pound=20 shilling; 1 shilling= 12 pence; 1 guinea金币= 21 shilling 银币
币值表示:pound--l; shilling--s; pence--d.
我算出1磅重的金块能铸934.5个shilling,折合46l 14s 6d[意思为46 pound 14shilling 6pence];但亚当斯密又说一盎司这样的金能够铸成价值为3l 17s 10.5d 的银币,我就搞不懂了。因为3l 17s 10.5d的银币倒推回去等于934.5shilling,而已经算出934.5的shilling是一磅金块所折合成的,又怎么成了一盎司金块相当于这些了呢?
哪些同学对这个感兴趣,帮忙做一做,我没有其他渠道可以问了。谢谢大家!
