crunchiness 和crispness 什么区别？Crunchiness is the gustatory sensation of muffled grinding of a foodstuff. Crunchiness differs from crispness in that a crisp item is quickly atomized, while a crunchy one offers sustained, granular resistance to jaw action. While crispness is difficult to maintain, crunchiness is difficult to overcome.这是维基百科解释的。。还是不理解。。
