超导性测定 一、科学研究中,想办法找途径的例子很多 二、如发现超导电性后,如何确定导体是超导体? 三、1914年 H Onnes想出的办法:

了解我国电力工业发展概况:掌握电力系统的基本概念及发电厂、变电站的常见类型;了解发 厂、变电站常用电气设备:掌握额定电压的确定方法

1、节理的定义 节理(joint)即岩石中的裂隙(fissure or fracture),是指没有明显位移的断裂。断裂包含节 理(无显著位移者)和断层(fault)(有显著位移者 2、节理研究的理论和实践意义 实际意义:1)矿液、石油、天然气运移通道、储 集场所,控制矿体形态。 2、地下水、石油渗透性,含 油性,含水性与节理发育的密度,开启性有关。3)影 响水工建筑物的渗漏性和岩体的稳定性
