成矿物质主要来源于火山岩，其中细碧岩可能提供较多的Cu，而石英角斑岩可能提供较多的Pb，Zn的来源则相对较广，细碧岩、角斑岩、石英角斑岩均提供较多的Au。

The widely-planted vegetable spinach and Lactuca sativa were selected as the research objects. Five different plots were chosen for each plant and five samples were selected in each plot by using plum-shaped arrangement method to form the mixed samples. The contents of Pb, Cd, Cu, Zn were determined and evaluated by single-factor pollution index method.

方法］以人们广泛种植的菠菜和油麦菜为研究对象，每种植物选取了5个地块，每个地块按照梅花形布点法，选取5个样品组成混合样品，测定其中的Pb、Cd、Cu、Zn含量并采用单因子污染指数法进行评价。

It remains disputable that birds can obtain geomagnetic information for homing because otoliths in the lagena are rich in elements Fe and Zn.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但这个假说目前还存在争议。

The macula lagena is innervated and has neural projections to the brainstem, but its physiological function is still unclear. It remains disputable that it is because otoliths in the lagena are rich in elements Fe and Zn that birds can obtain geomagnetic information for homing.

有人认为瓶状囊的耳石中Fe、Zn等元素含量较高，使得鸟类能够感受地球磁场而具有导航能力，但对于这个假说目前还存在争议。

The experimental result shows that after reclaiming the tailings with garbage fertilizer, Leucaena leucocephala Dewit. can grow well on the tin-zinc tailings pond while it is restricted in the tailings ponds without any reclamation; the contents of As, Pb and Zn in Leucaena leucocephala Dewit. are not high, only a little above those in normal plants.

试验结果表明：在用垃圾肥对尾砂进行改良之后，银合欢能在锡锌尾砂库上较好地生长，而在未经过任何改良的纯尾砂库上则明显受到抑制；银合欢不同组织中的As、Pb、Zn含量均不高，仅略高於一般植物的背景值。

The results shows that the young leaves and stems of the plant contained crude protein,crude fat,crude fibre,VB1,VB2,VB6,carotene,K,Na,Ca,Mg,Fe,Mn,Zn,Cu,palmic acid,stearic acid,oleic acid,linolic acid,linolenic acid,and and 17 kinds of amino acid.
