the machine has been used to detect gold.the machine has been using to detect gold.
the machine has been used to detect gold.
the machine has been using to detect gold.
这两句话所表达的意思一样吗语境分别是什么?

第一句很明显,就是【这个机器曾经被用来探测金矿,现在不用它了】
第二句很诡异,语法看似没错,其实语义模糊,翻译为【这个机器曾经用（什么别的东西）探测金矿,现在还在用（别的东西）了】这句好像机器在操控别的东西一样,但句子里没有给出,也不符合常识（除非有特殊语境,可惜没有）
如果想把第二句改成第一句的意思,应该说One has been using the machine to detect gold
