In Chapter Three, in order to correitly find the original meaning of GCTS, the author proposes that the traditional method of illustrating GCTS should be forsaken, which isolately compares and mechanically analogizes a character on tortoise shells with the form of present written charater, and insist that one showld study the text on tortoise shells itself and make a substitutional analysis of its radicals on the basis of structural theory.

第三章里笔者例释了一些在构形方式上具有一定典型特征的甲骨刻辞舆地文字的本来含义，在例释中没有囿于传统的只是孤立地拿某一甲骨文字与后世字书所载字形作机械类比的释字方法，而是坚持以殷墟甲骨文字自身结构特点为本体，进一步运用结构主义理论，对不同舆地文字中的不同偏旁部首进行替换分析，从而考释出许多素以为难释之字的本来含义，不仅丰富了传统的文字学理论，也为今后全面揭示各舆地文字之文化意蕴奠定了基础。

To get lattice materials with higher loading capacity than honeycombs and foams but much lighter,unit lattice cell structures were studied.

3D-CTM (Coupled Thermo-Mechanical Forming Simulation) software for precision forging process of aero-engine blade was developed. The key technologies of 3D coupled rigid-viscoplastic thermo-mechanical FEM simulation of blade forging process were studied systematically. By using the remeshing method of contracting from the boundary to the inner, new mesh system from old distorted mesh system can be obtained. A method of modifying the position of nodes touching on the die according to its original normal was proposed to avoid "dead lock" problem due to uncontinuity of normal of scatted die meshes. The pseudo-static iterative algorithm was used to simplify the coupled thermo-mechanical computation. In particular, formulations to determine relaxation factor β was established for rigid viscoplastic FEM adopting penalty function method, and an improved cubic factor rapid algorithm derived from these formulations was proposed by combining with the advantage of advance and retreat search method.
