1.
Through analysis of sandy material sediment sampling from a Tamarix cone with 132 clear sedimentary veins located at the west shore of Lop Nur,the research results are obtained as follows:all of the sandy materials of sedimentary veins in studied section mainly consist of the fine sand that occupies 42.
通过对罗布泊西南缘一个红柳沙包的132个清晰沉积纹层沙物质特征分析表明:所有沉积纹层沙物质均以细砂为主,占42。

The paper attempts to reflect the environment change in Lop Nur region by means of measuring the quantity of the Ca~(2+), K~+, Na~+,Mg~(2+) in the layer of the fallen leaves in the deposition sedimentary veins of Tamarix cone, in order to improve the way to study the environment change by studying the deposition sedimentary veins of Tamarix cone.
本文试图通过对红柳沙包沉积纹层中红柳落叶层的阳离子Ca~(2+)、K~+、Mg~(2+)、Na~+含量的测定来反映罗布泊地区环境变化的信息,以便完善红柳沙包沉积纹层作为干旱荒漠地区高分辨率环境信息载体的一种手段。
4) foreset bedding
前积层理
5) sediment laminae
沉积纹(壳)层
6) depositional lamination
沉积纹(微)层
补充资料：多层沉积层
分子式：
CAS号：
性质：由两种或两种以上相继沉积的金属构成的沉积层。这些沉积层可以由不同特性的同一金属或不同金属构成。如为了提高镍镀层的防护性，有时采用双层镍或三层镍镀层。又如为防护-装饰目的采用的铜/镍/铬三层镀层。
