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。

Wire electrode based on the trajectory of the different forms of control, WEDM can be divided into three types: one is shaped by the imitation controlled cutting in line in advance and work to create the same shape by mold, when processing the workpiece at the same time rough and on the mold clamping in the machine tool table, in the process of cutting wire electrode tightly against the mold on the edge of the track for the mobile, thus cutting out and die on the same shape and precision to the workpiece; another One is the electro-optical tracking control, to carry out the cutting line, before the basis of certain parts to enlarge the proportion of drawings depicts an electro-optical tracking map-processing machines will be placed in design stage of electro-optical tracking, tracking platform Photoelectric first line of graphics has always been to follow the track of the Mexican campaign, and then through the use of electrical, mechanical linkage to control the machine tool table, together with the workpiece so相似形wire electrode relative movement, thus cutting out the same shape and design to the workpiece; again a digital control, the use of advanced automatic control of digital technology-driven machine tool in accordance with the pre-processing parameters according to the workpiece geometry pre-processing procedures for the preparation of a good CNC auto-complete processing, the production does not require appearance on board the need to map to enlarge map of the previous two form of control has a higher machining accuracy and a broad range of applications, both at home and abroad more than 95% have adopted WEDM NC.
根据对电极丝运动轨迹的控制形式不同,电火花线切割机床又可分为三种:一种是靠模仿形控制,其在进行线切割加工前,预先制造出与工件形状相同的靠模,加工时把工件毛坯和靠模同时装夹在机床工作台上,在切割过程中电极丝紧紧地贴着靠模边缘作轨迹移动,从而切割出与靠模形状和精度相同的工件来;另一种是光电跟踪控制,其在进行线切割加工前,先根据零件图样按一定放大比例描绘出一张光电跟踪图,加工时将图样置于机床的光电跟踪台上,跟踪台上的光电头始终追随墨线图形的轨迹运动,再借助于电气、机械的联动,控制机床工作台连同工件相对电极丝做相似形的运动,从而切割出与图样形状相同的工件来;再一种是数字程序控制,采用先进的数字化自动控制技术,驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工,不需要制作靠模样板也无需绘制放大图,比前面两种控制形式具有更高的加工精度和广阔的应用范围,目前国内外95%以上的电火花线切割机床都已采用数控化。切割属电加工范畴,是由前苏联人发明的,我国是第一个用于工业生产的国家,当时由复但大学和苏州长风机械厂合作生产的这是最早的机型叫复旦型,我们国内在此基础上发展了快走丝系统。欧美和日本发展了慢走系统LS

Such doubts havesitimulated the researchers'curiosity and start to explore the students' terms This research proceeds by observation interview test using learning sheets and etc The purpose is to explore students' terms of scientific concepts sources of terms connections between students' usage nomenclature and chooses of usage The results of the research are as follows: 1 There are five kinds of naming principles for students' terms of scientific concepts: appearance habit function replacing and sound Appearance principle contains three categories: color shape and partial construction; habit principle contains custom and ability; replacing principle contains reality and non-reality 2 Students' terms of scientific concepts come from two ways: self-acquisition and learning through senses The former way is only a bit more common than the latter 3 There are three different relationships between students' usage of terms and nomenclature: one both the same in usage and meaning; the other both different; another different usage but the same meaning Normally terms that students used are various from nomenclature in the aspects of usage and meaning only a few would match and even rare for "Synonyms" to occur 4 Alternative options for students' scientific terms are maintenance adaptation or co-existence with formal scientific terms The most common way of selecting usage of terms is to maintain Sometimes students would adapt themselves once learn of scientist's term However some believe that very odd chances for both could exist at the same time
这样的疑问深深引起研究者的好奇,著手探索学生科学概念所使用的语言。本研究透过观察、访谈、学习单施测等方法来进行,目的在探讨学童在科学概念上所使用之学生惯用语、学生惯用语来源、学生惯用语与科学家用语之关联性、学生惯用语选择。研究结果如下:一、学童在科学概念上所使用之学生惯用语的命名原则有五种:外型、习性、功能、藉代称呼及声音,其中外型原则有颜色、体型及部份构造三类目,习性原则有习惯及能力两类目,藉代称呼原则有实体及虚拟两类目。二、学童在科学概念上所使用之学生惯用语有两种来源,分别为自己称取和听来。学生惯用语来源较多为自己称取,透过其他方式听来少一点,但两种来源的比率差距甚小。三、学童在科学概念上所使用之学生惯用语和科学家用语的关系有三种,分别为用语意涵均相同、用语不同意涵相同和用语意涵均不同。学生惯用语通常和科学家的用语是不同的,且其意涵也不同,只有部份学生惯用语和科学家用语意涵均相同,至於学生惯用语和科学家用语不同但意涵相同的极少。四、学童的科学概念相关学生惯用语选择有三种,分别为维持学生惯用语、改变成科学家用语和科学家与学生惯用语皆可。学童的科学概念相关学生惯用语选择,以维持学生惯用语最多,而有些时候学生会在得知科学家的用语后改变成科学家用语,但认为科学家用语和自己使用的学生惯用语皆可的则很少。
