The gold medals that will be awarded in London this year will be the biggest and heaviest handed out at any summer Olympics.
2012年伦敦奥运会上所颁发的金牌将会是史上最大也是最重的金牌。
At 400 grams （14 ounces）they will be 17 times heavier than at the 1912 Olympics in Stockholm.
每块金牌重400克（14盎司），其重量为1912年斯德哥尔摩奥运会金牌的17倍。
On the other hand, the 1912 games were the last one where gold medals were made entirely of gold.
不过，1912年奥运会是最后一届采用纯金打造金牌的奥运会。
Now they consist mainly of silver with a thin coat of gold—6 grams is the minimum requirement.
现在的金牌主要成分是银，只在表面镀一层不少于6克重的纯金。
The London medal will have a gold content of only about 1.5%， andat current prices will be worth $706.
本届伦敦奥运会的金牌含金量仅为1.5%，折合现在的金价约为706美元（约合人民币4250元）。
Calculations by The Economist find that this is much more than the "podium value" of any previous gold medal(based on estimates of the composition of medals and bullion prices at thetime, adjusted for inflation). This is partly because gold and silver pricesare now historically high and partly because this year's medal is so muchheavier, even though the extra weight is silver rather than gold.
根据《经济学人》杂志的计算，伦敦奥运金牌的价值将超过以往任何一届的金牌价值（根据当时的金牌成分和价值估算，并考虑了通货膨胀的因素），因为现在的金银价格都达到了历史最高点，即使多出来的重量是白银而不是更贵的黄金。
For the first time, the silver in this year's "gold" medal is actually worth more than its gold content.More over, if the metal content of earlier medals is valued at today’s bullion prices, the London gold is worth only just over half of those handed out in 1912.
本届伦敦奥运会金牌中的白银价值首次超过了其中黄金的价值，而且如果把之前金牌含金量的价值按照现在的牌价计算的话，伦敦奥运会金牌的价值仅比1912年奥运会的一半多一点而已。
