中學數學課堂教學中優化和完善學生的數學認知結構的必要性,從數學學習的一般過程看,數學學習就是新的學習內容與學生原有的數學認知結構相互作用,形成新的數學認知結構的過程;從有意義學習理論看,學生所學的任何知識,都不是零碎的、彼此孤立的,而應按知識之間的關系,通過不同層次來構成知識的結構,建立知識之間的相互聯系;從信息加工理論看,如果人們採用「結構」的形式合理有效地組織必要的信息,成為「組塊」 ,可以讓更多的信息濃縮進不多的組塊,從而擴大工作記憶能力,而完善認知結構是使人的思維適應龐大的長期記憶的一種有效方法;從建構主義理論看,數學學習是指主體在把新知識與多方面的各種因素建立聯系的過程中,建構新知識與各方面因素間的網路構架,從而獲得新知識的意義。Besides, two particular working conditions, filling a vessel with gas and sucking gas out of a vessel, are discussed in detail, and the equations for calculating the time for gas filling and suction are presented
