描述：本文从未喷施过稀土的天然生长的茶叶中分离出了一种含有稀土元素铈的化合物。|In this paper,a compound containing cerium (Ce) was isolated from native tea leaves, which was not sprayed by rare earth elements(REEs).
描述：本文首先分离了茶叶中各主要成份；然后进一步分离出一种含有稀土镧的化合物。化学组成分析结果与茶叶中典型的脂多糖组成基本一致。|In this paper,the cellulose、greasesoluble substance、tea multiphenol、unpurified protein ate were isolated from tea,which was not sprayed by rare earth elements(REE),and the content of rare earth
描述：本文用AES法对茶叶中微量元素Fe,Cu,Mn,Zn的形态分析进行了研究。|In this paer,The speciation of Iron, Copper, Manganese and Zinc in tea leavies are determiced by atomic emission spectromotry.
描述：本文选用未喷施过稀土的茶叶为研究材料。试图研究稀土元素在植物体内的分布和定位，为探讨稀土对作物的增产机制提供重要的信息。|Tea not spraying rare earth was chosen as studied material.We attempt to study the distribution and location of rare earth elements (REEs) in plant and to provide important information for the i
