摘要
灸绒品质是影响灸疗的重要因素,传统灸绒以三年陈为佳,但缺乏科学数据。该文以一年陈、三年陈的九牛草绒和蕲艾绒(叶绒比10∶1)为研究对象,采用扫描电镜(SEM)、Van Soest法和同步热分析方法,研究一年陈、三年陈的灸绒的燃烧热品质差异及其影响因素。结果表明九牛草绒燃烧为热能均衡型,三年陈在140~302℃集中释放热量9998.84 mJ·mg^(-1)(占J总的54%),产热效率为122 mW·mg^(-1),在302~519℃释放7512.51 mJ·mg^(-1)(占J总的41%);蕲艾绒燃烧释热特征属于热能突释型,三年陈在140~311℃释放热量16695.28 mJ·mg^(-1)(占J总的70%),瞬时效能为218 mW·mg^(-1),在311~483℃释放热量5996.95 mJ·mg^(-1)(占J总的25%);燃烧参数(-R_(p)、-Rv、Di、C、Db等)表明,三年陈灸绒的燃烧热品质较一年新绒更佳,具有更大的燃烧热量、产热效率、易燃性、燃烧温和持久性以及较高的瞬时燃烧效率。该文利用科学数据阐明了九牛草可作为优良的灸绒使用,三年陈灸绒的品质优于一年陈。研究结果为九牛草绒的深度开发及灸绒质量标准的提升提供了科学依据。
The quality of moxa is an important factor affecting moxibustion therapy,and traditionally,3-year moxa is considered optimal,although scientific data are lacking.This study focused on 1-year and 3-year moxa from Artemisia stolonifera and A.argyi(leafto-moxa ratio of 10∶1)as research objects.Scanning electron microscopy(SEM),Van Soest method,and simultaneous thermal analysis were used to investigate the differences in the combustion heat quality of 1-year and 3-year moxa and their influencing factors.The results showed that the combustion of A.stolonifera moxa exhibited a balanced heat release pattern.The 3-year moxa released a concentrated heat of 9998.84 mJ·mg^(-1)(accounting for 54%of the total heat release)in the temperature range of 140-302℃,with a heat production efficiency of 122 mW·mg^(-1).It further released 7512.51 mJ·mg^(-1)(accounting for 41%of the total heat release)in the temperature range of 302-519℃.The combustion of A.argyi moxa showed a rapid heat release pattern.The 3-year moxa released a heat of 16695.28 mJ·mg^(-1)(accounting for 70%of the total heat release)in the temperature range of 140-311℃,with an instantaneous power output of 218 mW·mg^(-1).It further released 5996.95 mJ·mg^(-1)(accounting for 25%of the total heat release)in the temperature range of 311-483℃.Combustion parameters such as-R_(p),-Rv,Di,C,and Db indicated that the combustion heat quality of 3-year moxa was superior to that of 1-year moxa.It exhibited greater combustion heat,heat production efficiency,flammability,mild and sustained burning,and higher instantaneous combustion efficiency.This study utilized scientific data to demonstrate that A.stolonifera could be used as excellent moxa,and the quality of 3-year moxa surpassed that of 1-year moxa.The research results provide a scientific basis for the in-depth development of A.stolonifera moxa and the improvement of moxa quality standards.
