Based on the polynomial blending function, a kind of blending function-blending function class and a new type blending function-rational one are deduced.

从多项式型混合函数出发，通过数学变换，构造了一类混合函数—混合函数类。

One class might inherit from another. This relationship is called IS-A, as in, "a Hand is a kind of a Deck. ""

一类可能继承了其他的类。这种关系也可以叫做『是一个』，比如说，『一手牌就是一种牌的组合。』
