Money really does grow on trees – at least in Australia.
树上真的可以长黄金——至少在澳大利亚是如此。
Scientists have found gold in the leaves of eucalyptus trees.
科学家们在桉树树叶里找到了黄金。
The particles are much too small to be seen with the naked eye but have been detected using a type of x-ray that is especially good at picking up trace amounts of metals and minerals.
这种树叶中含有的黄金粒子十分微小,不足以凭肉眼观察到,但是科学家们通过一种专门探查微量金属和矿物的X射线仪器发现了它们。
However, gold hunters shouldn’t start felling gum trees in the hope of becoming rich.
但是,猎金者们大概不能通过伐木来采金致富。
Study leader Mel Lintern told the Brisbane Times: ‘If you had 500 eucalyptus trees growing over a gold deposit, they would only have enough gold in there to make a wedding ring.’
科研小组的领队梅尔·林特恩对记者说,“如果让500棵桉树生长在一个金矿上,这些树中收集到的金子大概足够打一枚金戒指。”
The real value of the study is that nature’s own version of gold leaf could provide mine companies with an inexpensive and environmentally friendly indicator of where to drill test sites.
这一研究的真正价值在于,这种自然界而非小说里出现的金叶子可以充当金属探测器,这种探测方式既环保又方便,可以告诉探勘者在哪里能开采到金子。
