The third chapter deduces the universal rules in the process of derivation. The substitution rule shows the nature of representations in two levels, the structure and the semantic levels with the features of combinatory and paradigmatic relations. The major parameter variations are interpreted with a weight on dislocation of word and the multi-functions of Wh-word in the frame work of the syntactical asymmetry. The fourth chapter further discusses the innate reasons of the English Wh-move and Korean Wh-in-situ in the syntactical system after summarizing the main findings of the comparison.

而后，在第三章采用演绎方法对英朝Wh-问句转换生成的共性规则，即指代规则在结构和语义两个层级上的指代特征及其聚合组合关系特征进行了分析；以句法不对称性为理论依据，以错位语序和wh-词的一词多功能为着眼点，对主要参数差异进行了生成解析；在第四章，对英朝Wh-问句对应关系和上述对比研究进行归纳总结的基础上，在句法系统中进一步讨论了英语WH-移位与朝鲜语WH-原位的言内原因。

Moreover, the hot compressive deformation behavior of the RS/PM AZ91 magnesium alloy and AZ91 alloy matrix composite were also investigated, the conclusions are drawn as follows:1. The processing parameters of the atomization-twin rolls quenching technology were optimized as follows: the diameter of the nozzle 1mm, the wheel velocity 25m/s, the pressure of atomization gas 0.3MPa and Ar gas for melt injection 0.1MPa. The RS AZ91 alloy flakes exhibited fine and uniform microstructures. When the flakes were extruded at 673K, extruded velocity of 0.1mm/min and extrusion ratio of 25:1,the magnesium alloy rods with clean surface, uniform dimension and excellent mechanical properties were obtained.2. The RS AZ91 magnesium alloy powders prepared by atomization-twin rolls quenched technology exhibited fine equiaxed grains with the grain size of 1-3μm, the phase constituent included supersaturate solid solution phaseα-Mg and miner fineβ-Mg_(17)Al_(12) phase. The as-extruded materials also exhibited equiaxed grains with the size of 5-7μm and a large number of fineβ-Al_(12)Mg_(17) and fewer AlMg_2Zn phases were detected in the alloy.
