This paper aims to illustrate the necessity of testing oral english ability in college english test by studying the status quo of college english teaching , backwash effect and validity , then puts forward some suggestions on oral english testing methods and how to improve college students ' oral english ability 從當前英語口語教學的現狀、測試對教學的反拔作用、測試的效度這幾方面探討了增設專科英語口試的必要性，并就口語測試方法以及如何提高學生口語能力提出建議。

Regional theory directs space locating of daily urban system periphery in daily urban system or broader region range . centre - periphery theory require the development of daily urban system periphery think over radiant function of daily urban system center , and try to make trickling - down effect have more power than backwash effect . competitive edge theory and innovation theory explain that daily urban system periphery plays an important role in daily urban system in chongqing municipality and supports a selected measure of accelerating development in beibei district 區位理論指導著都市圈外圍區在都市圈及更大區域范圍中的空間定位；核心一邊緣理論則要求，都市圈外圍區的發展應充分考慮都市圈核心區的輻射作用，并積極實現“涓滴效應”強于“回波效應” ；競爭優勢理論和創新理論則認為，都市圈外圍區在重慶都市圈中將會扮演重要角色，也支撐著北暗區實現加速發展的途徑選擇。

Education should know and utilize educational criticism resource , respond to its comment , and create good conditions for the development of educational criticism . education should put up a flat roof of elevating the making of educational criticizer , promote the development of higher education and construct the system of lifelong education and learning society . in conclusion , through scanning educational criticism , which is a social and educational phenomenon with great backwash , the paper bends itself to explore good ways for educational criticism and educational development of the 21st century 要正確認識和積極面對教育批評，教育必須正確認識教育批評的來由和價值，敢于承擔責任，保持理性;要合理開發和利用教育批評資源，對民眾批評強烈的話題進行甄別和研究，和批評界交往與對話，并正視問題、積極改進;還要努力搭建提升教育批評者素質的平臺，加快高等教育的發展，并構建終身教育體系和學習型社會，以此為教育批評的發展與提升創造良好的生態環境和條件。

As backwash is the key of renewing and keeping up the function of filter , so some factor optimization experiments of backwash have been done . the optimum operating parameters of air scour and water backwash of ceramics media are chosen by multiple factors experiments : qa = 15 l / s ? m2 , qw = 5 l / s ? m2 , t1 = 1min , t2 = 5min , t3 = 5min 經多組實驗正交分析結果后得出了涂鐵陶粒濾池反沖洗實驗的最佳參數組合：氣沖強度15l / s ? m2 ，水洗強度5l / s ? m2 ，單氣預沖1min ，氣水同時反沖洗5min ，單水漂洗5min 。

The results showed : fiber ball has the highest efficiency among the three , its water - consumption is small in backwash and it is more wear - resisting ; the comprehensive property of quartz grain filter material is poorer ; manganese grain has an effective removal of fe ( superscript 2 + ) and mn ( superscript 2 + ) but water - consnmption is big 結果表明纖維球濾料除鐵濾速高，反沖洗耗水量小且耐磨損；石英砂濾料綜合性能次之；錳砂雖然除鐵效果較好，但反沖洗耗水量大。

Further , full - scale experiments were carried out and the results demonstrated that the up - flow filtration with coarse media was efficient in removal of suspended solid , backwash of cleaning , and long action cycle . an effluent turbidity of 1 ntu was always achieved with an average filtration rate of 20 m / h 生產規模的運行實驗顯示粗石英砂濾料上向流過濾對懸浮顆粒的去除是有效的，反沖洗干凈徹底，過濾周期長，當平均濾速為20m h時，出水濁度為1ntu 。
