变斑晶晶内包体径迹在变质地质学和构造地质学中具有广泛的用途。尤其在造山带研究、PTt轨迹、变质与变形关系及历史、变形机制及褶皱和剪切带运动学、变质变形程度、变斑晶生长率、应变量、应变速率等方面的应用取得许多重大进展。其中所有变斑晶都是同运动的、未旋转的“固定论”新观点、新应用，值得重视和深入综合研究。另外，在任何应用之前都宜首先确定变斑晶旋转与否。

Porphyroblast inclusion trails are very useful in metamorphic geology or petrology and structural geology, which include orogenic models and their PTt paths, the relationship and history between metamorphism/deformation, shear sense and folding,porphyroblast growth rate, strain rate and strain, deformation degree and metamorphic grade, etc. The applications and problems of porphyroblast inclusion trails in some aspects mentioned above are discussed. Especially new idea and applications of fixism of synkinematic, no-rotation porphyroblasts are very important and necessary to study further more.Before every kind of application of inclusion trails, whether porphyroblasts rotate or not rotate must be firstly determined.

Key words: Porphyroblast, Inclusion trails, Microstructure, PTt paths.
