主要是經濟增長速度偏快，結構性矛盾突出，發展方式粗放，資源和環境代價過大，物價上漲壓力增加，體制機制性障礙還沒有根本消除。 -
But along with the population increase, economic development and natural condition change, the dry and water deficient situation becomes increasingly serious, the drought occurrence frequency, scope and impacting area expand successively, in the meanwhile, some structural and systematic obstacles existed in long - term drought fighting work have emerged and the drought fighting work faces unprecedented trial
但是隨著我國人口增加，經濟發展和自然條件變化，我國乾旱缺水的形勢日益嚴峻，旱災發生的頻率、范圍和影響的領域不斷擴大，同時，長期抗旱工作中存在的一些體制、制度性障礙也顯露出來，抗旱工作面臨前所未有的考驗。 -
Although various mechanics models have put forward many numerical techniques, the widely used one that is commonly admitted by engineers is the finite element method. combined the joint elements, on some extent this method could overcome structural surface obstacles described by the mechanics of continuous media such as the joint of canny existing in the inner of rocks. until now, the finite element method has been widely employed because of the mature of the large - scale construction computing software
針對各種力學模型提出了多種數值方法，最廣泛使用的並獲得了工程界普遍承認的是有限元法，有限元法結合節理單元可以一定程度上克服連續介質力學在描述巖體內部存在節理裂隙等結構面的障礙，目前有限元法由於大規模結構計算軟體的成熟而為工程界所普遍運用。 -
By analyzing resolving process of several groups of typical fraction applied problem, this research put the test paper as the start point. the paper point out that there are five obstacles student will encounter in the " process of fraction applied problem. those are : ( 1 ) obstacle of cognitive level of student ; ( 2 ) obstacle of black mathematical cognitive structure ; ( 3 ) obstacle of the problem representation ; ( 4 ) obstacle of structural character ; ( 5 ) obstacle of problem resolving strategy
進而根據測試卷的解答情況，從測試問捲入手，通過對幾組典型的分數應用題解答過程及結果的一般性分析，依託問題解決理論，對小學分數應用題的解答障礙進行了初步研究，得出結論：學生解答分數應用題會遇到五種障礙，分別是： （ 1 ）小學生的認知水平障礙； （ 2 ）小學生的不良數學認知結構障礙； （ 3 ）分數應用題問題表徵障礙； （ 4 ）分數應用題的結構特徵障礙； （ 5 ）分數應用題問題解決策略障礙。
