说明：  计算了一个时间序列的多尺度排列熵，可以用于金融时间序列和生理时间序列的复杂性分析。(The multi-scale permutation entropy of a time series is calculated, which can be used to analyze the complexity of financial time series and physiological time series.)

framebuffer 设备即帧缓冲设备（简写fb）提供了显示接口的抽象描述。他 同时代表着显示接口的存储区，应用程序通过定义好的函数访问，不需要知道底 层的任何操作。-framebuffer equipment that frame buffer (abbreviation fb) provided a display interface to the abstract depiction out. He also represented the storage and display interface, application function by defining good visit, does not need to know the bottom of any operation.
