A novel compound——N-naphthalene acylN′-substituted p-chlorobenzamido thiocarbamide was synthesized by reaction of p-chlorobenzamido hydrazine and α-naphthalene acyl mustard oil,which was obtained by potassium thiocyanate combined with α-naphthalene acyl chloride formed from α-naphthylacetic acid and SOCl2 in anhydrous benzene.

通过α-萘乙酸和SOCl2在无水苯中反应制得α-萘乙酰氯，然后与硫氰酸钾反应生成α-萘乙酰基异硫氰酸酯，再与对氯苯甲酰肼进行加成反应，合成了新型化合物N-萘乙酰基-N′-对氯苯甲酰氨基硫脲，用薄层色谱法跟踪最后一步反应，确定了反应时间。

苏联列宁格勒纺织科学研究院研制了用聚酯纤维作芯纱，棉纤维作编织层的，一次捻成两股、三股和四股的右捻向高强力线的生产工艺。

He modeling is the thin walled column model in which the shear walls connected each other in horizontal are regarded as a thin walled column, and the part between openings in vertical are regarded as a tie beam. The programs based on this kind of model is TAT.
