Tooby and Cosmides proposed some rules about functional analysis:①functional analysis should be expressed in adaptationist terms,②a set of phenotypic properties is not an adaptation if it is transient, varying from individual to individual,③adaptations should be distinguished from their expression (which may vary from context to context),④a set of phenotypic properties is not an adaptation if it was absent in the environment of evolutionary adaptedness,⑤a set of phenotypic properties is not an adaptation if it did not solve an adaptive problem in the environment of evolutionary adaptedness.

图比和考斯米戴丝提出了功能分析的原则：①功能分析应该用适应的术语来表达；②一系列表现型的特点如果是暂时的，在不同的个体身上发生变化，它并非是一种适应；③适应应该与它们的表现（在不同的情景中可能发生变化）区分开；④一系列表现型的特点如果在进化适应性环境中不存在，则不是一种适应；⑤一系列表现型的特点如果不能解决进化适应性环境中的一种适应性的问题，也不是一种适应。

Results show that:(1) For each particle size of andalusite, variation tendency of the properties of the material is generally the same: the maximum of bulk density, compressive strength and rupture strength appears in the range of 5%-10% content of fiber, these properties of the material remarkably decrease as the fiber content exceed 10%; while at the same fiber content, the properties of the material increase with the increase of firing temperature.
