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.
