Proved is actually the older form of the past participle; proven is a Scottish variant that was first introduced into wider usage in legal contexts:
Proved 实际上是过去式的较早形式； proven 是这个词的苏格兰语变体， 它首先在法律领域得到广泛的使用：
例句：
The jury ruled that the charges were not proven.
陪审团判定指控不成立。

Both forms are now well established in written English as participles:
现在这两种形式在书面英语中作为分词已完全被接受：
例句：
He has proved (or proven ) his point.
他证明了（或 proven ) 他的观点。

例句：
The claims have not been proved (or proven ).
那些要求权没有被证实（或 proven )。

However,proven is more common when the word is used as an adjective before a noun: a proven talent.
然而，当proven 放在名词前用做形容词时更为常用： a proven talent
