针对嵌入式课程的教学方法,指出现有教学方法存在的不足,提出一种基于SPOC和翻转课堂相结合的嵌入式课程教学方法,具体阐述基于SPOC和翻转课堂的嵌入式课程教学方法的四个阶段:前端分析、课程设计、课堂教学和评价.

Based on the analysis of restoration methods of noisy image and probability density function of pulse noise ,a kind of restoration algorithm on pulse noisy image based on a pixel is proposed .The pixel is scanned in a given order and is judged whether it is a pixel with the pulse noise data or not .If it is a noisy pixel ,the output of a kind of spatial filter is computed and the pixel data is replaced .Otherwise it is unchanged .The experiment results show that it is a kind of spatial filters based on the pixel processing and it has the advantages of no sorting operations ,short execution time and keeping the image details .

Through the analysis of the function of turbine bypass system and running condition,we design this controlling method which is automatic control in different stage and it is suitable to work on the large turbine power unit in China.This article gives the design for fixed value forming,parameter adjusting,protect and blocked mode operation logic;adjusting the steam parameter of boiler exit and turbine entry when the power units start or stop; protect mgreheater and condensation heat transfer when the power units start or stop;extra steam reclaim.
