摘　　要：在电视显微镜上安装一组步进电机能实现自动粗调焦和等距移动标本。用8031单片机应用系统控制步进电机的运转，在功率放大器中选用IRF530场效应管以提高系统的性能和可靠性。这种显微镜与微机组合，构成普及型显微图象处理系统的硬件基础。To mount a group of stepper motors on a television microscope automates the instrument in coarse focussing and equi-spaced moving a specirnen. A microprocessor 8031 application system is used to control the stepper motors. For enhancing the properties and reliability of the system, we select RIF 530, a field effect transistor for the power amplifier of the motor. Combination PC with the instrument becomes basic hardware of a universal microscopic image processing system.
