电离层TEC反演,读取CODE文件,转化为某一地点的TEC(Ionospheric TEC inversion, read the CODE file, into a place of TEC)

一个简单又高效的日志系统 本文给出一个性能高，使用简单的日志解决方案。本模块实现日志信息的批量写入文件，定时自动flush到文件中，写入文件的日志级别可动态调整，单个日志文件大小可配置，循环对日志文件写入，这样不会造成机器空间被日志文件耗尽。(A simple and effective logging system In this paper, a high-performance, using a simple log solution. The module to achieve volume of information to write the log files, from time to time automatically flush to a file, write to the file log level can be dynamically adjusted, a single log file size can be configured, cycling on the log file is written, this will not cause the machine space is the log File exhausted.)
