Computer aided instruction ( cai ) and computer aided test ( cat ) have been widely used as computer technologies develop dramatically , but the instruction way and equipment of the belt drive test trail the development of today ' s engineer technology 随着计算机技术的飞速发展,计算机辅助教学( cai )和计算机辅助测试( cat )技术已得到了广泛的应用。然而,带传动的实验手段和设备却落后于当今技术的发展水平。
In order to meet the needs of precision control of motion of the physical treatment and automatically operation , it was elaborately designed to enlarge the market of the domestic and international in high level medical equipment with the help of computer aided test system , the equipment was comprehensive test online 为确保该设备能在限定的时间内准确地完成医生设定的治疗动作,以计算机辅助测试系统为手段,对该设备整机运行状态进行在线综合测试与分析。
With the development of society ' s information technology , the tradtional teaching in education ca n ' t satiefy students " requirement to diversificational knowledge for student . a variety of computer aided instrucation software have been applied for the teaching pratice from primary school to campus . the segment of teaching - - - - - - - compterization in examination have caught everbody ' s eyes more and more . the computer aided test can relief teachers " work in examination . for example , papers organization test , marks determinant . result analysis . it will deduce the factor that people bring in mind subjiectively . anf orginaze the test safelier , more quickly and more impersonal it can promote the teching quality and efficiency 计算机考试能够减轻教师在测验这一教学环节的许多劳动(如编制测验、评阅分析等) ,可以相对减少考试各环节的人为主观因素,更快速、更客观、更安全地组织考试工作,把教师从繁重的组卷、评卷、成绩分析等工作中解放出来,对提高教学质量和效率能起到良好的促进作用,基于计算机的考试系统已经被广泛地应用于各种考试中。
The main target of the research is to design and manufacture a cat ( computer aided test ) system of joint internal thread , in order to improve the measuring accuracy and quality of the joint internal thread of bao steel inc . this paper analyzes the success and limitation of the former design , and introduces a double probe system 本文目的是研究开发一套接触式油管接头内螺纹计算机测量系统,满足宝钢公司提出的内螺纹检测的要求。论文在分析前人研究设计中的成功经验和不足的基础上,提出了双针测量的系统方案,并对测量系统的数字滤波、算法模型和误差分析进行了深入的研究。
Multiple used all conclusion of deduction , combined the result of the data in site , the choice of probe , and information of equipment , take face - to - object programme method , use visual c + + 6 . 0 to develop computer aid testing system of y tubular joints . through the system , it produced the result automatically and rapidly 综合所有的推导结论,同时结合现场数据,探头选择,仪器信息等方面的结果,采用面向对象的编程方法,利用visualc + + 6 . 0开发出了y型管节点超声探伤计算机辅助系统,通过该系统可以实现声束传播的模拟,自动快速地生成探测结果。
