Chener gold deposit is located in north of xunmadao fault , the types of ore are gold - brazil - quartz of vein and gold - multimetal - quartz of vein . the occurrence of gold - bearing quartz vein is controlled by ductile - brittle shear zone , most the occurrence of gold - bearing quartz vein included by schistous zone and cracked zone , in the strike direction of gold - bearing quartz vein , it " s high content and great thickness appear on nww , in the direction of tilt , it " s high content and great thickness appear on the part of transformation from big angel of tilt to small angel of tilt 矿石类型为金-黄铁矿-脉石英型和金-多金属硫化物-脉石英型。含金石英脉受韧-脆性剪切带控制，主要赋存于片理化带与破碎带中。在脉体走向上，北西西向脉体品位高，矿体厚度大；在倾向上，南倾，倾角较缓处品位高、矿体厚度大。
And the generalized homothetic composite action of metallogenic subsystems mentioned above formed the multiple - composite metallogenic system of the jiangda tectonic belt . the typical ore deposits of jiangda tectonic belt , such as dingqinnong , jiaduoling , renda etc , are contact metasomatic type deposits formed intracontinental rifting stage , and the tectonic - magmatic - hydrotherm of intracontinental orogenic stage superposed and rebuilt some preexistent ore body . their space distribution is controlled by composite intrusive rock belt of ne direction 对丁钦弄、加多岭、仁达等典型矿床的研究表明，它们均为形成于陆内裂谷作用阶段的接触交代型矿床，陆内造山期的构造?岩浆?热液作用叠加改造了先成矿体，矿床空间分布受北东向复合侵入岩带控制。
Exhibition of the deposit is controlled by the regional ductile zone , and the ore ' s distribution has been controlled by the secondary ductile zone ( controlled mine ductile zone ) , the brittleness structure of later stage possess the specified reconstruction and damage to the mineral ore , at the same time it also strengthened gold once more wealthy anthology 区域性韧性剪切带控制了矿床的展布，而次级韧脆性剪切带(控矿剪切带)控制了富矿体的分布，后期的脆性构造对矿体有一定的改造、破坏作用，同时也加强了金的再一次富集。
Yanchang series is a typical low permeability reservoir , and its favourable sandstone reservoir is delta facies . heavy compaction , cementation and heterogeneity exist in it . according to the analysis of the main control factors of forming the secondary pore , it is held that the secondary pore in longdong area is controlled by both favorable facies belt and abnormal formation pressure . it is also held that the formation of the abnormal formation pressure is due to the dewatering of the clay mineral during diagenesis because the dewatering time is identical with the decarboxylation time of organism . organic acid and co2 are driven to adjacent favorable reservoirs under the abnormal formation pressure , and a lot of secondary pore is produced in the runners . from the present exploration result , it is useful to predicting the development of secondary pore to study the distribution of abnormal formation pressure 陕甘宁盆地三叠系延长统是国内外典型的低渗特低渗油田，储集层主要为三角洲砂体，压实作用和胶结作用强烈，储层非均质性非常严重，因此预测次生孔隙发育带是寻找油气聚集带的关键.通过对陕甘宁盆地陇东地区延长统次生孔隙形成的主控因素分析，认为陕甘宁盆地延长统次生孔隙的形成除了受沉积有利相带控制外，还与地层异常压力的作用密切相关.研究认为陇东地区异常压力的形成机理主要由于成岩过程中粘土矿物脱水作用.粘土矿物大量脱水时间正好与有机质脱羧期相一致，从而在异常压力作用下将生油岩中的大量有机酸及co2带到与之相邻的储集层中，并沿着有利储集相带运移，在酸性水经过的地方形成大量的次生孔隙，为后期油气运聚提供有利通道及宿住空间，从现今的勘探结果来看，通过研究地层异常压力纵横向分布特征，并结合有利相带研究预测次生孔隙育良带是行之有效的方法
The system realizes multiple serial port communication and management by way of multi - port serial board ( 2 ) use the database technology to manage and manipulate the physics information data of nc tool . the basic information management system , the nc program auto - create system , the simulation of cutter working and dnc communication program are integrated to one system . it realizes the offline programming and controls of no - punched tape , helps to cut short the supplementary cutting time and improves the efficiency of to program and machine tools and realizes the separation and seamless connection of program and manufacture 本课题以硬件为辅助手段，以软件为主要手段实现了以下功能：以串口扩展卡来实现网络中多台数控机床的通信和管理；使用数据库技术对数控机床的物理信息进行管理和操作，将数控机床基础信息管理系统、 nc程序自动生成模块、刀具加工轨迹仿真模块和dnc通信接口模块集成为一体，实现了数控加工的离线编程和数控系统的无带控制，提高了编程效率、质量，缩短加工辅助时间，提高了机床的效率，既实现了编程和加工的分离，又达到它们之间的无缝连接。
