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.

结果表明：(1)对于不同粒度的原料，性能变化规律大致相同：在同一烧成温度下，体积密度、常温耐压强度、常温抗折强度在5％～10％之间出现峰值，加入量超过10％之后材料的性能明显下降；在相同的纤维含量下，随着烧成温度的提高，试样的各项性能均有所上升。

It also gives the definitions and stochastic properties of pure random process, random walk process and AR(1) autoregressive process, and analyses the simulative data of three typical random processes using wavelet analysis, frequency spectrum analysis and time-correlation analysis. The stochastic properties of time series and the trend component, the time length of time-correlation and the properties of main frequency of these three typical random processes are summarized as the templates for further research.

给出了包括纯随机过程、随机游走过程和 AR(1)自回归过程等在内的基本随机过程的定义和统计特征，并运用小波分析，时间相关和频谱分析对这三种基本随机过程的模拟数据进行分析，归纳出它们在时序上的随机特征、低频信号趋势项特征、时间相关的长短以及主频信号的位置等特点，作为研究 GPS 接收机误差和多路径效应的随机特征的模板。

Second, in the viewpoint of crypto analysis, the practical requirement for the cryptographic function is to construct the function that can resist all the known crypto analysis and attacks. In advanced, the main cryptographic properties are compared, and the relation among these cryptographic properties is analyzed, including the trade-off ones. Get the conclusion that the construction of cryptographic Boolean function is to find out the proper Boolean function in the whole vector space under the restriction of several cryptographic properties required for the security system.

然后本文从密码分析的角度，讨论了密码函数的实际需求，即构造能够抵抗已有密码分析与攻击的布尔函数；分析了布尔函数的主要的密码学性质，并比较了这些性质之间的相互关系，包括制约的关系；得出了构造布尔函数的实质的结论，即在向量空间中构造全体布尔函数，以所需的若干密码学性质作为限制条件，用有限域上的多项式、Walsh谱、Hadamard矩阵等数学工具找出适当的布尔函数用于加密体制的设计。

The article introduces the character of alpaca's serration. It also test, alpaca's processing properties, Such as length, fineness, crimp, frictional properties and so on. After test and measurement, it compares alpaca's properties with cashmere, botany wools and 64s wool.

Decision properties are derived from constraints and are primitive data representing the status of design objects Performance properties calculate decision properties and the domain are bounded by design constraints.

决策参数是从限制条件中抽象出来的数据，代表设计对象的属性或状态；表现参数是对决策参数的计算和度量；限制条件规范及限制表现参数的域值，可视为类不变量，每个类对象都必需满足之。

Different cells,cell density and cell shape lead to comparatively great difference in wood properties and physical mechanical properties, change of wood cells affects change of wood properties including wood quality,wood property and all other aspects,and wood properties decide economic value and directly affect manufacturing and utilization of wood,therefore,the research and analysis on wood cell structure become especially important.

由于树木生长不均匀，使各种树木的木材构造具有多样性，不同细胞体、细胞密度和细胞形状导致了木材材性和物理力学性能存在较大差异，木材细胞的变化影响着木材性质的变化，木材的性质又决定木材经济价值，并直接影响木材的加工和利用，由此对木材细胞结构分析研究就变得尤为重要。

It subdivides the electro-market of inner Mongolia in the fifth part of dissertation, in this basis, take the electricity of the total society demanding as the main factor, take the electricity of industry demanding divided by properties and electricity of district demanding divided by district as the subordinate factor, definitude the core target market of inner Mongolia electric power corporation divides up Baotou, Huhehaote and Wuhai according to district, industry and other electro-market according to properties; the main target market divides up Bameng and south west of Ximeng according to district, according to properties is agriculture market and resident market; the subordinate target market divided up Xuejiawan, Wumeng, Yimeng according to district, according to properties is merchandize and bite and sup, material supplied and sold and warehousing, traffic transporting and post communication, geological survey and exploration and construction market.
