Trivial(平凡)和Non-Trivial(不平凡)是对于class(类)的或者类中的四个函数而言的: 1.构造函数 2.拷贝构造函数 3.赋值函数 4.析构函数 Trivial 其中Trivial(平凡)的概念本人的理解是无意义的,Trivial是相对于Non-Trivial而言的。 Non-Trivial 对于Non-Trivial而言的,如果上面四种函数满足以下三点任意一项或一项以上...

A method of classification based on color and morphological differences of the mesocarp is described for determining the developmental stages of fresh peanut [Arachis hypogaea (L) 'Flo-runner'] pods. Developmental stages are designated as Classes 1-7, with each subsequently numbered class representing...
