The risk of related complications is low but they can be severe, with vision deteriorating to 20/200 or finger counting ability in some cases.


Position is accurately determined by using the PICs counting ability to add or subtract pulses from a nominal 200 steps to ensure exact position.




 Nine experiments with similar procedures to test children's conceptionof cardinal and ordinal numbers and their ability in additionsubstractionoperations have been carried out in nine districts throughout China. A totalof 780 aged 37 yrs has been tested and 9 experimental results have beenreported. This paper is a general summary of these nine reports.

Nine experiments with similar procedures to test children's conceptionof cardinal and ordinal numbers and their ability in additionsubstractionoperations have been carried out in nine districts throughout China. A totalof 780 aged 37 yrs has been tested and 9 experimental results have beenreported. This paper is a general summary of these nine reports. Based on thedata obtained the following problems are disccussed: a) the development ofthe child's counting ability; b) the development of the child's conception ofgroup and additionsubstraction operations; c) the development of the child'sconception of seriation and the relationship between cardinal and ordinalnumbers; d) the child's conservation of number; e) the development of thechild's mathematical reasoning; f) the part different cognitive processesplay in the child's conception of number; g) the stages and turning pointsin the development of the child's conception of number; h) the role ofcultnral background in develoing thechild's conception of number and operational ability and; i) the interrelation between different stages or aspectsin the development of the child's conception of number and operationalability. This study, as the authors point out, is still in its prelimilary stage.However, quite an amount of scientific data has been obtained and someproblems for further investig ation have been derived. Even more important, the authors have gained some experience in this form of cooperativeresearch, which will be useful in our future work.  这个报告中的初步研究工作在做法上甚有可取之处,在收获上也令人感觉到有广阔的前途。但诚如作者自己所说,这项初步研究工作还有不少不足之处,很有待继续努大加以充实和提高。我们希望有更多同志共同探索各种做法,研究有关问题。  This report is a followup study of the number concept masteringprocess of a 45 year old child.

This report is a followup study of the number concept masteringprocess of a 45 year old child. The result shows that under conditions ofeffective training and adequate drilling, the procedure of the child to masterpreliminary number concept enters a critical year. Counting and writingnumbers, using numbers as signs to calculate are most prominent in thisprocedure. To read and memorize the table of order of numbers, trying,error and sudden realization, counting fingers as a selfhint, transforms intothe development of the ability of oral counting. Counting according to differentnumber order is the main content in the development of oral counting. Thedevelopment of ability to count articles is obviously prior to the developmentof ability to count numbers orally. The development procedure of the first oneis: Counting one by one, counting by groups, and counting by parts. In fact,to read and memorize the different numeral tables will enable the child tounderstand and realize the basic types of numbers, the combining types ofnumbers and the relationship between them. Writing numbers is thedevelopment of counting ability, that will be "set", in the form of matter. Infact, reading and writing numbers are the main methods that will enable thechild to master and operate the "wordformation", of numbers, and promotethe development of counting ability, It is also an essential method used bythe child in raising his number conception level. In the course of masteringnumber concept by the child, the development procedure of calculating abilityis: plus and minus one by one, plus and minus by groups, and plus andminus with dividing and grouping of numbers. Calculating numbers (plus,minus, multiplication and division) is the method used by the child in learningnumber formation., it is also an important mothod used by the child in raisinghis level of conception of numbers.  本文是用纵向法,对一个儿童(四周岁至五周岁),掌握数概念的过程,进行追踪研究,提出的报告。 研究结果表明:在有效的训练和充分的练习条件下,被试掌握最初数概念的过程,进入关键性的一年。在这过程中,读写数字、用数字作为符号进行运算,具有特别突出的地位。认读顺序数字表,转化为口头计数能力的发展,是以尝试错误、用手指自我暗示、顿悟为中介。按各种数序进行计数,是口头计数能力发展的主要内容。按物计数能力的发展,明显地比口头计数能力的发展,处于领先的地位。按物计数能力发展的程序是:逐个计数,按群计数,成组计数。认读各种数字表,使被试在实际上,理解和领会数词的基本类型、组合类型及其内在联系。书写数字就是把计数能力的发展,以物质的形式“固定”下来。读写数字使儿童在实际上,掌握和运用数词的“构词法”,促进计数能力的发展,是提高儿童数概念水平的基本方面。被试在掌握数概念的过程中,运算能力发展的程序是:逐个加减,按群加减,利用数的分解、组合进行加减。数的运算(加、减、乘、除),是儿童学习数的组成之手段,是提高儿童数概念水平的重要方面。  ：This measuring system is applied in steel rolling line． Its structure is distributed communication network based on RS485 serial bus． Two infrared temperature instruments are adopted for temperature acquisition and for recognizing moving direction of billets as well as for realizing billets count ability． A program is developed to fulfill the function of temperature acquisition， the communication of network， temperature alarm， file management and counting of billets．  介绍一种应用于轧钢生产线钢坯出炉温度和支数的在线测试系统，系统结构为RS485总线通讯网络，采用两个辐射测温仪测量钢坯温度并判断钢坯运行方向，从而实现支数计数功能。系统软件完成温度采集、网络通讯、温度报警、文件管理及钢坯计数等功能。   << 更多相关文摘
