【摘要】 验评工作是仪器行业发展必须开展的工作之一。尤其对于国产仪器而言,验评工作是打破国产仪器研制与应用矛盾的有效途径。本文针对如何改进国产仪器主观验评的方法展开相关研究,详细阐述了如何利用基于建模的迭代机制改善主观验评,提出了一种可迭代改进的国产仪器主观验评方法,并且利用此方法对DH1798可编程恒功率直流电源和DH2794A直流程控电子负载两个仪器进行主观验评,进一步分析了该方法的可靠性和实用性。更多还原

【Abstract】 Evaluation work is one of the tasks that must be carried out in the development of instrumentation industry. Especially for domestic instruments, the evaluation work is an effective way to break the conflict between the development and application of domestic instruments. This paper focuses on how to improve the method of subjective evaluation of domestic equipment. We have carried out relevant research and elaborate how to use the model-based iterative mechanism to improve the subjective evaluation. We raise a subjective evaluation method which can be iteratively improved domestic equipment. With this method, we subjectively evaluate two devices : DH1798 programmable constant power DC power supply and DH2794 A DC programmed electronic load, and further analyze the reliability and practicability of the method.更多还原
