摘　　要：详细介绍了基于台湾研华PCI-1710数据采集卡的多通道智能化同位素测厚仪的设计原理、系统构成和具体实现。讨论了同位素测厚仪的基本原理、实际测量中必须考虑的修正因子及仪器标定的复杂性。给出了多通道智能化同位素测厚仪的整体设计框架;PCI-1710卡的功能、特性、开发步骤以及在本系统中的具体应用;软件子系统的开发流程和主要功能模块。最后,给出了以241Am低能γ射线源作为工作源所实现的多通道智能化同位素测厚仪的特性和应用范围。The designing principle, the constitutionof system and the implementation of multi-channel intelligence isotope thickness gauge are introduced in the paper in detail, which are based on multifunction card PCI-1710. The paper also discusses the primaryprinciple of isotope thickness gauge, correct factor in measurement and complicationof calibration, in the following, the whole frame ofmulti-channel intelligence isotope thickness gauge is given. The functions, the characteristics and the usage of multifunetion card PCI-1710 are described. Furthermore, the developing process and the function modules of software are presented. Finally, the real prototypeof multi-channel intelligence isotope thickness gauge is introduced, using ^241 Am as a radioactive element.
