The control system of mould level is crucial to improve the slab quality in the continuous casting process, pid controller is used in the traditional mould level control, and it has some defaults, such as : at the start - up or finishing period of casting or during the changeover of tundish, pid control has a bad effect, its overshoot is large and its transient time is long ; the erosion of the tundish stopper and the submersed nozzles lead to the accuracy of control become bad ; the abrupt falloff of block in the submersed nozzles makes the level acutely fluctuate, and pid control can not overcome the disturbances resulted from the change of casting speed
結晶器液位控制系統是提高連鑄產品質量的關鍵環節，傳統的連鑄機液位控制方法採用常規的pid控制，存在如下不足：開始、結束澆注和換中間罐澆注時，控制效果差，超調量大，過渡時間長；塞棒頭和浸入式水口被腐蝕后引起控制精度差；浸入式水口堵塞物的突然脫落所引起的液位劇烈波動；無法克服拉速波動引起的擾動。 -
This text is on the basis of defining the education justice concept thinks that education justice including the questions not only caused by system factors, such as educational stratification system, system of enrollment in a nearby school, the tuition system and the doctrine orientation that the city in the education system has priority, but also includes the inequitable phenomenon of education that the human factors caused, such as the teachers and students lead to. the author carried on the analysis one by one to these factors at the same time points out no matter which factor leads to inequity in education is only damage the average children ' s normal right of educating, hinder the improvement of the integral level of chinese education and influence the society ' s justice realization finally
本文在界定教育公正概念的基礎上，認為教育公正既包括了因制度因素引起的問題，比如教育分流制度，就進入學制度，教育收費制度以及教育制度中的「城市優先主義」傾向，也包括人為因素導致的教育不公現象，比如教師和學生雙方因素。同時對這些因素進行了逐個分析，指出無論哪一種因素導致的教育不公正，只會損害就學兒童正常的學習權利，阻礙中國教育水平的整體提高，最終影響社會公正的實現。 -
