The work of this paper may offer some reference and gist for research on astrometry and geodesy.

本文的工作可为天文大地测量的研究提供一定的参考和依据。

In Astrometry, the term is applied to the difference between the observed position of a reference star and the position listed in the star catalog.

在天文上，本术语指的是观测的参考星的位置与星表上的该星的位置的差值。

This value is prescribed only vaguely by many authors with no reference to any significance level. This paper will give out an asymptotic critical value in a fixed significance level and an asymptotic p-value for testing by means of extreme value theory in order to detect outliers in AR model.

本文运用极值理论给出诊断AR模型异常点选取临界值的分布近似方法，这种方法选取的临界值可保证控制在一定的显著性水平下，而且还可以计算出检验的渐近p值，比一般仿真选取的临界值更科学合理。

The foundation of this system provides a good reference to promote the standardization and intelligence of the overhaul and maintenance of vacuum switches. This paper develops a special HF pulse power supply for internal pressure estimation, which achieves the output of HF-HV sinusoidal pulse wave whose frequency and amplitude can be modified respectively, and meets the design requirements according to the results of Simulink simulation and practical experiments. With the help of AT89S52, this paper designs an I~2C serial bus based signal detection system for peak value signal acquisition of HF pulse currents, which communicates with the upper computer by asynchronous serial communication for uploading the data. In the upper computer, a human computer interface is developed by Matlab software, whose functions are to do some computation and graphic display, such as calibrating the relation curve of vacuum degree and peak value of HF pulse currents, vacuum degree computation, and vacuum lifetime evaluation analysis basing on grey forecasting model as well as making relative suggestions.

本文研制了用于真空度检测的高频脉冲电源，通过Simulink仿真和试验检验其满足设计要求，实现了电压幅值和频率独立可调的正弦波高频高压脉冲输出；利用以AT89S52为核心基于I~2C串行总线的信号检测系统实现高频脉冲电流峰值信号的采集，通过异步串行通信实现单片机与计算机之间的数据通信，将检测数据传至上位机；在上位机利用Matlab开发人机交互界面，实现相关数据处理和图形显示，包括真空度——高频脉冲电流峰值关系曲线标定、真空度数值计算、基于灰色预测模型的真空寿命评估分析和提出相应决策建议。
