Abstract： Pulsars have significant academic and application value in fields such as astrophysical evolution, physics, timing, deep space autonomous navigation, and gravitational wave detection, making pulsar survey and application one of the current hot topics in the astronomical community. In order to explore the current research status and future development trends in the field of pulsar survey and application, 964 relevant articles were screened from the Web of Science (WOS) database. Building upon the analysis of core articles, in-depth exploration was conducted utilizing data analysis and visualization methods. The study results reveal that research in the field of pulsar survey and application has progressed through initial exploration and steady development phases, and is currently experiencing vigorous growth. Close collaboration among nations has led to the formation of three major research groups in this field. Pulsar survey and application research are anticipated to yield significant scientific research value and practical application outcomes in the future, such as direct detection of gravitational waves and advancements in deep space autonomous navigation, thereby further enriching and diversifying the research domain of pulsars.

Abstract： 控制系统能衔接、集成和管理射电望远镜的软硬件系统。控制系统中的序列化工具可将射电望远镜中不同设备、操作系统、编程语言和网络之间传输的信息进行编码和解码，增强系统之间数据的传输效率。本文分析和比较了三款二进制序列化工具Msgpack、Protobuf和Flatbuffers的编码原理及特性，并通过一个实例测试了它们的序列化数据大小、序列化时间和CPU利用率。结果表明，Msgpack的综合性能优于Protobuf和Flatbuffers，适用于周期长、需求易变的射电望远镜系统之间传输信息的编码和解码。
