个人计算机(PC机)在大中小学的应用日益广泛,而扩展表软件在物理实验室中逐渐成为实验数据处理的最强有力工具。扩展表软件可以毫无遗留地列出实验数据,进行即时计算,并绘出函数图象。这一软件也能用于课堂教学,以解决课内无法进行繁琐计算的困难。下面以热传递为例,说明扩展表 The application of personal computers (PCs) in primary and secondary schools has become increasingly widespread, and the extended spreadsheet software has gradually become the most powerful tool for experimental data processing in physical laboratories. Spreadsheet software can list experimental data without leaving any space, perform immediate calculations, and plot functional images. This software can also be used for classroom teaching to solve the difficulty of tedious calculations in class. The following uses heat transfer as an example to illustrate the expansion table
