补充资料:有限应变
      由无数个无限小应变叠加而达可测量程度的总应变。有限应变是研究变形构造,进行应变测量的重要概念。从初始应变积累到现在的有限应变称为全量应变。由无限小应变叠加为有限应变的进程称为递进变形。将形成有限应变的连续过程划分为有限个间断过程,各间断过程里增加的应变量,称为增量应变。
  
  有限应变测量是利用地质标志物的变形结果对岩石的有限应变进行定量测量。如果标志物的原始大小和形状已知,则可测出该处岩石的应变全貌,即主应变值和主应变方向。如果仅仅知道标志物的原始形状(例如圆球)而不知道原始大小,则只能测出主应变轴之比和主应变方向。变形标志物有砾石、鲕粒、化石、结核、还原斑以及自形矿物等。
  
  有限应变测量的原理是应变椭球体和有限应变莫尔圆的几何特征。依据不同的已知条件现已提出的测量方法有20余种,目前应用较多的是平面应变测量。世界上有个别地区曾进行过三维应变测量。但是利用应变测量获得的大区域完整的应变图象还很少。
