Abstract: It will help us understand the developing law and impact on science and technology development visualizing and comparing the developing trend, stages, network structure, subject fields and overlapping of scientific instrumentation (SI) and engineering instrumentation (EI). The results show that, both the developing trends and stages of SI and EI are striking similar; the developing trends appear to be polynomial trend; including four stages as infancy, steady developing, rapid increasing and high speed increasing; sub-network called electrical and electronic is the biggest one to both SI and EI networks; chemistry is the biggest subject for SI, and computer science is the biggest subject for EI; EI depends on SI more in the latest more than 50 years. The impact of SI and EI on science and technology development will be further explored next.

摘要： 分析与比较科学仪器和工程仪器的发展趋势、发展阶段、网络结构、学科分布和重叠比例等特征，有利于帮助我们了解科学仪器和工程仪器的发展规律，及其对科学技术发展的影响。分析结果显示，科学仪器和工程仪器的发展趋势和发展阶段都极其相似；1963-2011年间呈现出多项式增长趋势；经历了萌芽-持续增长-快速增长-高速增长四个阶段；“电气与电子”是科学仪器与工程仪器技术网络中的最大子网络；科学仪器分布最广的学科领域是化学，工程仪器分布最广的学科领域是计算机科学；在近50年的发展过程中，工程仪器对科学仪器的依赖性更大一些。下一步拟将继续探讨科学仪器与工程仪器对科学技术发展的影响等相关问题。
