Combining the deviation between thin layers' adjacent surfaces with the confining potential method applied to the quantum curved systems,we derive the effective Schr?dinger equation describing the particle constrained within a curved layer,accompanied by a general geometric potential V_(gq) composed of a compression-corrected geometric potential V_(gq)~*and a novel potential V_(gq)~(**) brought by the *** this analysis to the cylindrical layer emerges two types of deviation-induced geometric potential,resulting from the the cases of slant deviation and tangent deviation,respectively,which strongly renormalizes the purely geometric potential and contribute to the energy spectrum based on a very substantial deepening of bound states they offer.

20世纪初,北京、上海等地掀起了改编红楼戏的热潮,一时间,鼓词、摊簧、散套等多种说唱艺术纷纷追捧,形成红楼戏的辐射效应。《红楼梦》鼓词除已有单独发行的石印本以外,在期刊上亦有刊载,但因民国期刊史料过于零散繁杂,鲜少走入学者研究视野。事实上,刊载《红楼梦》鼓词是继案头红楼戏、红楼折子戏之后,与《红楼梦》散套、摊簧等并驾齐驱的说唱艺术,且因其文学底蕴深厚,传唱度较高,既是《红楼梦》小说逐渐走向通俗化的重要载体之一,又是值得进一步深入探索的经典个案。
