According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine l...

按 渗碳体形态特点，变形珠光体组织可分为以下3种类型：(1)不规则弯曲片层型，即变形后的渗碳体与轧制面呈大角度偏离且不规则弯曲的珠光体。(2)带有剪切带的粗大片层型，即被渗碳体剪切带分开且变形轻微的珠光体。(3)精细片层型，即与轧制方向平行排列、片间距细小且渗碳体严重变形的珠光体。精细片层区域的比例随着轧制压下率的提高而增大。此外，重度冷轧变形还引起渗碳体严重塑性变形和部分溶解。

The conception, studied objects and basic constituents of non-Smith strata are elaborated from theory level: Non-Smithian strata are the strata that have undergone mixing of different degrees, thus were deformed, metamorphosed and displaced into disorder totally or partially. They are the disorder parts in orogenic belts. Melange is the solo studied object of non- Smithian stratigraphy. The slices in melange is one of the basic constituents of non- Smithian strata, and also one of the basic units in the non-Smithian mapping. The slices used in this paper refer to blocks divided by small-scale tectonic boundaries and have certain constitutes. Superslices used in this paper refer to a set of slice association with similar tectonic deformation bounded by large-scale tectonic mixing.

从理论上阐述了非史密斯地层的概念、研究对象和基本构件：非史密斯地层（non-Smithian strata）是指那些经历过不同程度的混杂建造，并经历了变位，变形、变质，全部无序或部分无序的地层，主要指造山带地层中的无序部分；混杂岩是非史密斯地层的唯一研究对象；混杂岩中的构造岩片是非史密斯地层基本构件之一，亦是非史密斯地层和地质填图基本单位之一，岩片是指以构造拼合边界所分割的具有一定物质构成的地质体；物质建造形成于同一大的构造旋回期（如晋宁期、加里东期、海西期等）、亲源关系密切、大致经历了相似变形、变质历程的一套岩片组合体被称之为超岩片。
