摘　　要：非等轴颗粒付林图解由直线ａ＝１、ｂ＝１、ａ＝ｂ和曲线ａ２ｂ＝１、ａｂ２＝１分割成１０个微区，并对应于不同的ｅｘ、ｅｙ、ｅｚ组合和应变类型。这些直线和曲线分别对应于特殊的ｅｘ、ｅｙ、ｅｚ组合和岩石应变类型。岩石的应变类型有１８种。函数ａ．ｂ的表征方程有４种类型，并分别表征直线ａ＝１ｋ１和ｂ＝１ｋ２所分割的４个区间。ａ，ｂ表征方程的确定取决于岩石总的变形行为。此图解可用于非等轴颗粒标志体应变测量和应变类型的确定和图示。The Flinn diagram of anisometric grains are divided by lines a =1, b =1,and a=b ,and curves a 2b =1 and ab 2=1 into ten subregions,corresponding to ten different combinations of e x,e y,e z ,and strain types.The lines and curves represent the special combination of e x,e y,e z, and strain types.There are altogether eighteen strain types of deformed rocks.We have four equations to express a and b that represent respectively the four quarters divided by the lines a=1K 1 and b=1K 2 ,the equations of a and b depend on the bulk deformation behaviour of rocks.An application of the new diagram to determine the strain of deformed rocks as well as their types is here given.
