对测量专业中不同时期观测的数据进行精度是否相同进行统计检验(The measurement data of observation in different periods in the professional statistical test accuracy are the same )

过程工业蒸汽动力系统是过程工业的重要组成部分,它的安全、稳定运行是企业安全、稳定、长周期运行的基础。蒸汽动力系统的设计水平、运行和控制性能对过程工业的能量利用率和经济性具有重要影响,研究蒸汽动力 系统设计、运行、控制各层次的集成建模优化对于指导蒸汽动力系统全面优 化具有重要意义。 ( Industrial process steam power system is an important part of the process industry, it s safe and stable operation of the enterprise security, stability, long-term operation of the foundation. Steam power system level design, operation and control performance has a significant impact on energy efficiency and economy in the process industry, research steam power system design, operation and control of all levels of integrated modeling optimization guidance for full optimization of steam power system has an important significance)

自抗扰控制器自写，调节参数可用。含TD跟踪微分器，NLSEF非线性反馈律，ESO扩张状态观测器(Self rejection controller is self written, and the adjustment parameters are available)

matlab的标定工具箱,功能强大.可进行摄象机标定(matlab calibration toolbox and powerful. camera calibration can be carried out)

This toolbox is meant to facilitate the manipulation of images and video in Matlab. Its purpose is to complement, not replace, Matlab s Image Processing Toolbox, and in fact it requires that the Matlab Image  Toolbox be installed.    Emphasis has  been placed on code efficiency and code reuse.

说明：  就算hu矩中7个不变量代码。用于提取图像的不变形特征。(Even if hu 7 invariant moments in the code.)

本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)
