在現(xiàn)有面向?qū)ο筌浖攘糠椒ê投攘繙?zhǔn)則的基礎(chǔ)上，結(jié)合面向?qū)ο蠹夹g(shù)特性，對C&K面向?qū)ο蠖攘糠椒ㄟM(jìn)行了分析和改進(jìn)，提出了類的復(fù)雜性、類的方法個(gè)數(shù)等類規(guī)模的度量指標(biāo)，以及多繼承數(shù)深度、繼承方法比、繼承屬性比等類的繼承性度量指標(biāo)，并對這些指標(biāo)在工程實(shí)踐中的應(yīng)用進(jìn)行了討論。改進(jìn)后的度量指標(biāo)可以有效地補(bǔ)充C&K方法，優(yōu)化度量結(jié)果。Based on the study of object-oriented software measurement and the characteristics of object-oriented technology, some improvements on C&K metrics suite are discussed in this paper. Some new metrics for class size and class hierarchy measurement are presented including complexity per class, number of methods, depth of multi-inheritance tree and number of father etc. Meanwhile, the applications of these improved metrics in software engineering are discussed. All the improvements can supplement C&K metrics and optimize the result of measurement.
