Renovation of Introductory Physics Laboratories

9452145哈蒙国际州立大学物理系将翻新其入门物理实验室，以提高质量和成本效益，并增加该计划的技术相关性。专业的工作环境要求熟悉使用计算机来获取和处理数据。本科实验室可以提供一个很好的介绍数据处理技术与计算机由于相对简单的主题材料。最近廉价的模拟和数字计算机接口设备的发展使数据收集和分析更加灵活，并增加了可用于介绍性实验室的实验的范围和种类。为了利用这一优势，ISU物理系将建立一个计算机实验室，这将是美国第一个使用新的智能实验室接口和软件的实验室。这个极其复杂的系统是基于EXCEL for WINDOWS的，允许用户轻松地使用WINDOWS环境的全部功能来设计实验室或教学环境。硬件接口由若干a /D和D/ a转换器、计数器、定时器等组成，它们从WINDOWS环境中获取数据并控制进程。这允许访问OLE（对象链接和嵌入）、DDE（动态数据交换）、访问486芯片的保护模式、1兆字节以上的内存可用性等，从而最有效地利用所请求类型的WINDOWS平台的功能。

9452145 Harmon The Department of Physics at ISU will renovate of its introductory physics laboratories to improve quality and cost effectiveness and to increase the technologic relevance of the program. The professional working environment calls for familiarity in the use of computers to acquire and manipulate data. Undergraduate laboratories can provide an excellent introduction to data manulipation techniques with computers due to the relative simplicity of the subject material. Recent developments in inexpensive analog and digital computer interfacing equipment allow more flexibility in data collection and analysis and increase the scope and variety of experiments available for use in introductory laboratories. To take advantage of this, the Department of Physics at ISU will establish a computer laboratory that will be the first in the USA to utilize the new Intellecta Laboratory Interface and software. This extremely sophisticated system is based around EXCEL for WINDOWS and allows the user to easily use the full power of the WINDOWS environment to design a laboratory or instructional environment. The hardware interface consists of a number of A/D and D/A converters, counters, timers, etc. that acquire data in and control processes from the WINDOWS environment. This allows access to OLE (object linking and embedding), DDE (dynamic data exchange), access to the protected mode of the 486 chip, availability of memory above one megabyte, etc. and thus makes the most efficient use of the power of WINDOWS platforms of the type requested.
