In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

本文重点以老厂矿田中的接触带锡铜矿床和脉状矿床为研究对象，采用化学分析、ICP-MS、X射线粉晶衍射分析、电子探针等测试手段，对本区与成矿相关的基性-超基性火山岩、花岗岩、夕卡岩、电气石-石榴石等进行了系统的地质地球化学研究，研究表明：个旧矿区中三叠纪个旧组地层中的火山岩为钙碱性玄武岩-拉斑玄武岩系列，岩石为辉石-角闪石-长石-绿泥石-金云母组合；本区的花岗岩为过铝质花岗岩，主要与燕山期碰撞造山作用有关，锡多金属成矿与形成时代最晚、分异较好的花岗岩关系密切；本区夕卡岩中的有用共生组份随着夕卡岩类型及其矿物组合的不同具有明显的分带性。

Therefore, when the grid technique or the district was applied to regionalize spatial scale, individual soil profile are needed more to reduce uncertainties of the estimate of soil organic matter in the grid or the district with spatial scale up, but the uncertainties are smaller when using soil organic matter content in wellestimate gird or district to estimate the grid or district without available data by extrapolation.

因此，采用网格法或行政区划分空间区域，获得空间区域单元内土壤有机质含量或贮量的精确估算需要较多的剖面，但外推至数据不足的空间区域时，估算的不确定较小；采用土壤分类单元为空间区域单元，结果则相反。

The method employs characteristic values such as hinge node voltage at dividing place between the large district grid and the provincial grid and tie line reactive power and so on as a coordinated variable of wattless control of the large district grid and the provincial grid, and real-timely calculates an optimal set value of the coordinated variable in the large district grid which is sent down to the provincial grid via wide area communication. In the coordinated control of the provincial grid, the method can not only realize the control object of original grid, but can also realtimely track the optimal set value of the coordinated variable given by the large district grid.

本方法选择大区电网与省级电网分界处枢纽节点电压和联络线无功等特征量作为大区电网与省级电网无功控制的协调变量，通过大区电网的无功优化，实时计算出大区电网中协调变量的最优设定值，该设定值通过广域通信下发到省级电网，在省级电网的协调控制中，除了满足本级电网的控制目标外，还实时跟踪由大区电网给出的协调变量的最优设定值。
