The source and formation mechanism of methyl carbamate in liquor covered the followings:①methyl carbamate formed by spontaneous chemical reaction of carbamide and methanol in fermented and undistilled alcoholic beverage;②in alcohol produced by grains as raw materials, cyanide precursor of grains formed into cyanate during fermentation and distillation, which further developed into methyl carbamate in alcohol.

白酒中氨基甲酸甲酯的来源和形成机理主要有：①在已发酵的和未蒸馏的酒精饮料中尿素和甲醇自发的化学反应生成氨基甲酸甲酯；②以谷物为原料生产的酒精中，氨基甲酸甲酯形成的途径来源于谷物的氰化物前体在发酵和蒸馏时反应形成的氰酸盐，氰酸盐在酒精中转化为氨基甲酸甲酯。

To the materials , there are rare dislocations in their crystal grains; to the unstrengthened samples, there are many dislocations which well-distributed in their grains; and to the strengthened samples, there are a large amount of dislocations scattered along their grain-boundaries, that is, the dislocations form a dislocation wall which is of great dislocation density.

又经透射电子显微镜对各种样品微观组织结构进行分析，发现其位错组态明显不同：①原材料样品中的晶粒内仅存在有非常稀疏的位错线；②未经过强化的样品中可观察到大量均匀分布的位错，分布密度相对较高；③在经过低载锻炼强化的样品中，可观察到大量的晶粒内在晶界附近聚集着一道密度很高的位错墙。
