摘　　要：基于虚拟仪器和电子万能试验机自行开发出一套结构简单、操作方便的微小土壤粘附力测试系统, 弥补了传统粘附力测量仪器无法测量微小粘附力的不足,最小粘附力测量值可达0．003N,系统的硬件设计主要 是带有限位保护装置的载物台,系统软件通过虚拟仪器软件编程语言DASYLAB和VC实现。The development process of the testing system of Data Acquirement for Tiny Soil Adhesion is introduced in this paper. The developed system is operated conveniently and easily, based on the virtual instrument and a common testing machine. It can overcome the lack of the conventional facilities, which cannot test tiny factors. The minimum soil adhesion force is 0. 003 N by this system. The main component of the developed instruments is a set of carrier-plat with limited position device. Program-mings software...
