The authors hold that the joint actions of numerous factors such as the upper mantle uplifted zone ( the mantle thinned zone of lithosphere ) , the upper mantle anomalous area ( relatively low - velocity area ) , the uplifted zone of intracrustal high - conductivity layer , the deep fault ( shear zone of lithosphere ) , the margin of the crust - upper mantle uneven masses , the basement uplifted area reflected by gravity high , the magmatic belt and tectonic intersection reflected by skipped magnetic field , control the distribution of auriferous skarn deposits and copper ( associated with gold ) skarn deposits 作者认为，上地幔隆起带（岩石圈地幔减薄带） 、上地幔异常区（相对低速区） 、壳内高导层隆起带、深断裂（岩石圈剪切带） 、地壳上地幔不均匀性块体的边缘、重力高反映的基底隆起区、跳跃磁场反映的岩浆岩带和构造交汇处等诸多因素的共同作用控制著含金夕卡岩矿床和铜伴生金夕卡岩矿床的分布。
The main task for electronic control system is to rebuild the current minitype double - roller cast machine into automation and to monitor the process of continuous casting technology including sample - data showing and controlling . it ' s useful to study the continuous casting technology of thin belt tech and what ' s the parameter effect on the process of the continuous casting and the final products . it ' s also helpful to raise the accuracy , to get better control performance , to accumulate the experience of continuous casting automatic control 整个系统由液压控制系统和电控系统组成，电控系统的主要任务即是对现有实验用小型双辊铸机进行自动化改造，实现对连铸过程的监控，包括参数的采集显示和实施控制等，以便于深入探索薄带连铸工艺，研究各种工艺参数对连铸过程和最终产品质量的影响；以及提高控制精度、获得更好的控制性能、积累连铸系统自动控制方面的生产经验。
