不饱和羧酸包括烯酸和炔酸,就是分子内含有烯键和炔键 的羧酸。分子内含有两类官能团,即:=,三和-COOH. 根据不饱和键和羧基相对位置的不同,不饱和羧酸可分为 a,B-和B,不饱和羧酸,我们主要讨论羧基和烯键直 接相连的a,B-不饱和羧酸

There are many concepts that are used in fuzzy logic that sometimes become useful when studying fuzzy control. The following problems introduce some of the more popular fuzzy logic oncepts that were not treated earlier in the chapter or were treated only briefly (a)The complement(\not )of a fuzzy set with a membership function has a membership function given by A(x)=1-u(x). Sketch the complement of the fuzzy set shown in Figure 2.6 on page 30 (b)There are other ways to def ine the\triangular norm\for representing
