Taking it for example that zhujiabaobao section of panzhihua vanadic titano - magnetite deposit , the paper detailedly analysed its change regularity in ore texture and structure , mineral composition and content , ore chemical composition , mineral chemical composition , rare element " s change feature of rock and ore , exploding temperature of mineral inclusion . on the basis of above , the feature of rhythmic texture of ore body in panzhihua vanadic titano - magnetite deposit was researched 本文以攀枝花钒钛磁铁矿朱家包包矿段为例，详细分析了该矿段中矿石组构、矿物成分及含量、矿石化学成分、矿物化学成分、岩石及矿石稀土元素变化特征、矿物包裹体爆裂温度等的变化规律，进而研究了攀枝花钒钛磁铁矿矿体中的韵律结构特征。
This text describes the project basic principle and system structure and capabilities of production equipment for mechanism and electric , according as require of blast furnace automation , analyzes the chemical reactions in blast furnace by principle , according as mass and energy balance principle build on process models and technology calculate , according as process optimization principle build on process system optimization models , and technology calculate , as one time , expert system command any model . the expert system contains a knowledge base , which already represents the concentrated know - how of blast furnace operation , gathered from many installations world - wide 本文在介绍了项目的基本原理和系统构成以及相关的生产工艺的基础上，根据高炉过程优化的要求，从机理上分析了高炉冶炼过程的化学反应，并依据质量能量平衡原理建立了工艺模型和技术计算，按照优化原理建立了过程系统优化模型，并在专家系统的调度下协调工作。系统还包括知识库，它总结了普通高炉操作的理论知识和控制理念，同时，结合钒钛磁铁矿的冶炼知识，形成具有攀钢冶炼特点的知识库。
And apatite . by these analyses and comparison with general granite both in china and the world and with the granite in other au or cu belt in china , the characteristics of the granite in this area are concluded as follows . it belongs to magnetite - i or syntectic granite and has crust - mantle mixed characteristics ; it was formed mainly by crystallization differentiation of melting magma and multiphase varied intrusion ; the degree of differentiation evolvement is not high ; the granite and its enclaves p . re congenetic ; the range of temperature is about 500 - 700 , the range of pressure is about 2 . 50 gpa - 4 . 35 gpa , and the range of oxygen fugacity ( lg fo2 ) is - 15 . 53 - - 14 . 00 ; most granite bodies formed before the collision of plates , and few formed after the collision of plates 通过对测试数据的分析与综合研究，并同中国和世界一般花岗岩类以及中国主要金、铜成矿岩体的花岗岩类进行对比，得出本区花岗岩类岩石具有以下特征：属磁铁矿-型或同熔型花岗岩，其岩浆物质具壳幔混源特征：主要由熔融态岩浆经结晶分异作用，通过多期变速上侵而形成；其分异演化程度较低；寄主岩基和包体具有同源性；岩石的形成温度范围约为500 - 700 ，压力大约为2 . 50gpa - 4 . 35gpa ，氧逸度值1gfo _ 2为- 15 . 53 ? 14 . 00 ；该岩带主要形成于板块碰撞前消减的活动板块边缘期，为燕山至喜马拉雅早期的大陆边缘火山弧环境的产物。
Sapphire from shandon and hainan commonly have the reaction border , we found out this reaction border enriched with fe , mg , and k by testing its components ; we also studied the inclusion in the sapphire , and found many kc1 crystal grain with variety of size , a melt inclusion enriched with k , si , is also found , this may suggest an assimilationary - magmatic course ; besides that , another minerl inclusions such as enstenite , magnetite , chromite , zircon are also found 3 、观察到了山东、海南蓝宝石普遍存在的反应边，并测试了反应边的成分，证实其以富fe ， mg ，和k为特征；研究了蓝宝石里面的包体，发现蓝宝石里面存在着大小不等的kcl的结晶颗粒，还发现了富k富si的熔浆包裹体，说明其形成过程中有同化混染的贡献；此外还发现了斜方辉石，磁铁矿，铬铁矿，锆石的包体矿物。
