There are theories with guidance for the development of the western part . in this chapter , no details touch the general traditional theories with guidance , and it only quotes some practical theories , which effect strategic decisions on the external opening and concrete measures for the western part , such as theory on development limit , gradient theory , balance and small balance theory and export basic theory 對西部地區具有指導意義的理論有很多,在本章中,沒有細談對西部地區對外開放具有指導意義的一般性傳統理論,而只涉及影響西部地區對外開放戰略決策和具體行動的實用理論:發展極理論、梯度理論、平衡與不平衡理論和輸出基礎理論。
Then , a practical approach of software quality evaluation based on this model is given out which uses the network method of nerve and combines the associative memory model with the expert judge and fuzzy appraisal according to the gradient theory . and a program of this approach is compiled using c # . net 然后,根據梯度理論,應用神經網絡方法將聯想記憶模型與專家評判、模糊評價相結合,給出一個基于此模型的軟件質量評價的實用方法,并用c # . net對此評價方法編程實現,最后通過實例來說明此方法。
