This paper discusses the kernel of the system -- geometric model and includes the following:(1) The topological elements and the relation between them in geometric modeling system are explained and expressed by the theory of simplicial complex and CW-complex. In addition, the identification operators and homology theory in algebraic topology are used in our model. A hierarchical structure is built on the base of complex.

本文主要讨论这个系统的核心问题——几何建模问题，包括以下几个方面内容：(1)用单纯复形和CW复形的理论来解释和表达造型系统中的拓扑元素和拓扑元素之间的相关关系，并将代数拓扑中的粘合操作和同调论应用到模型中，建立以复形为基础的层次结构。

The results showed that the herb was rich in vanadium and lithium and tin, but low in zinc and copper, and had a strong tendency to accumulate titanium, lithium and boron. The pharmacological effects of geo herbal Asarum L. seemed to be closely related with its characteristic contents of trace elements which were mainly affected by the idioplasm and various other minor factors.

结果显示，细辛道地药格中V、Li、Sn等元素的含量较高，Zn／Cu比值较低，细辛对Ti、Li、B等元素有较强的富集作用，细辛的药理活性与细辛道地药材的微量元素含量特征有一定的相关性，种质是影响细辛道地药材中微量元素含量的主要因素，从微量元素的角度来看，细辛道地药材的形成模式是以种质为主导的多因子关联决定型。

Based on the complexity of the sources for the sediments in the Okinawa Trough, the sequential extraction procedure was applied to the hydrothermal influenced sediments in the core H9 recovered from the middle Okinawa Trough. Five fractions, including exchangeable, bound to carbonates, bound to iron and manganese oxides, bound to organic matter, and residual were acquired. Based on detailed analysis for major, minor and rare earth element compositions, the distributions of the elements in various speciations of the sediments were determined and the controlling mechanism was discussed. The variations of hydrothermal signatures in the core, partitioned from the terrigenous, volcanic and biogenic materials, have been demonstrated and the accumulation rates of some elements were evaluated.

The composi tional change profiles of monazite demonstrate a heterogeneous distribution of e lements La, Ce, Nd, P, Th, Si, Ca and U. This was caused by the differences in geological environments, temperatures, pressures and compositions of the hy drothermal solutions.

根据微区剖面(0.18mm)元素分布曲线，指出了La、Ce、Nd、P、Th、Si、Ca和U等元素表现出8～10个微环带成分不均匀分布的特点，并认为成矿溶液的地质环境、温压和微量元素含量变化是不均匀分布的主要原因。

According to logging results of 167 boreholes and chemical analyses of 24 369 samples as well as characteristics of element distribution at 4 000 m, 3 950 m and 3 900 m levels, the deposit is characterized by alteration, mineralization and element geochemistry of the porphyry. Alteration and mineralization are spatially and temporally related to the augen quartz phenocryst_bearing hornblendequartz diorite porphyrite (J3δομ).

They have A/CNK values of 0.9～1.2, suggesting aluminum saturation or ersaturation, and are enriched in LREE and LILEs and depleted in HFSEs. Their δEu values are 0.11～0.32, evidently indicating plagioclase fractional crystallization.(87Sr/86Sr)i ratios and εNdvalues are 0.707?9～0.716?1 and -6.90～-7.70 for volcanic rocks, and 0.7086～0.7098 and -7.10～-7.68 for quartz syenitic porphyrite, respectively, implying that all the igneous rocks from the Yandang Mountain were evolutional products of co-magmas, and derived mainly from the crust, mixed however with mantle components.

岩石富集轻稀土元素和大离子亲石元素，相对亏损高场强元素；δEu值为0.11～0.32，表明岩浆经历了以斜长石为主的强烈结晶分异作用；火山岩(87Sr/86Sr)i为0.707 9～0.716 1，εNd为-6.90～-7.70，中央侵入体石英正长斑岩(87Sr/86Sr)i为0.708 6～0.709 8，εNd为-7.10～-7.68，表明它们是同源岩浆不同阶段分异演化的产物，物质来源主要为陆壳，但也有地幔物质参与。
