It also studies the causes of the checkout and the flexibility of employment result . it concludes that the increase of the economy is not the granger cause of nominal employment growth , that is to say , the increase of economy in china doesn ’ t promote of the nominal employment . the decline of the nominal employment elasticity from 1999 is not only because of the improvement of technology , the imbalance of the industry structure , transformation of system and the policy of interest rate , but also because of the inexact statistic data which makes the real employment underestimated 本文首先利用1978年至2003年的有關數據對我國經濟增長與名義就業的關系作了分析:根據有關計量經濟學理論,對數據作了平穩性檢驗、協整檢驗和格蘭杰因果檢驗,用建立回歸模型的方法測算出名義就業彈性,并對檢驗結果和就業彈性測算結果作了原因解析,認為我國的經濟增長不是名義就業增長的格蘭杰原因,即我國的經濟增長沒有促進名義就業的增長,我國的名義就業彈性自1990年以來呈下降趨勢,其原因除了技術進步、產業結構失衡、體制轉軌和利率政策外,還有由于統計的原因使得真實的就業增長被低估。

But the companies in our country are still confronting variable problems , such as the globalization of the market plants purchases , the changing customers “ needs and the inventory problems resulted from the inexact forecast . these problems embody the obsolete method of materials management and the lower work effect 但是,國內企業的經營仍面臨著多種多樣的課題,例如,市場、生產點、零部件采購的全球化,客戶需求的變動及其不規則性的增大以及所伴隨的商品供應和生產的不平衡導致缺貨或庫存增大等問題。

Based on analysis of the characteristic of the tourist urban environments , this paper pertinently proposed an inexact fuzzy multi - objective system programming and optimizing method . it is the first time that the inexact fuzzy multi - objective planning method is applied in the field of tourist urban environmental planning . and then , an inexact fuzzy multi - objective system programming and optimizing model for the tourist urban environment is also constituted . this model is not only integrated the kinds of environmental factors and economic factors , but also given full consideration to the uncertainty of the tourist urban environmental development . through the interactive process between man and computer , the ideas and knowledge of experts and decision - makers are combined with the model . so the scientific nature and practicability of the planning results are guaranteed 簡要分析了旅游城市環境規劃的特點,針對性地提出了一套不確定性模糊多目標旅游環境系統規劃優化方法,這是首次將不確定性多目標規劃方法應用于以旅游業發展為重點的城市環境規劃領域。并相應地建立了旅游城市環境不確定性模糊多目標系統規劃優化模型ifmopomtue ,既把各種環境要素和經濟要素有機地整合入模型中,又充分考慮了旅游城市環境發展的不確定性,通過人機交互式方法,將專家和決策者的意見落實在模型參數上,從而最大可能地保證了規劃結果的科學性和可操作性。

Because of its capability to emulate human thinking and human inference and to capture the inexact information of the plant , fuzzy logical controller ( flc ) often yields satisfactory performances 因為模糊邏輯控制能模仿人思考和處理問題的方式,抓住對象的不確切信息,所以模糊邏輯控制往往能夠取到令人滿意的控制效果。

But the pursure of equality is not be welcomed at all time , feminism had gotten bogged down because of the inexact state of equality . it is more and more difficult to define the “ equality “ 但是對平等的追求并非總是廣得人心,對平等的不確切表述也一度使女性主義運動陷入困境和低潮,要對平等下一個定義也越來越難。

Here , a complete mastery of the language , however stupid the children ; there , in most cases , even with people otherwise highly gifted , a faulty and inexact command 一邊是完全掌握了語言,不管孩子們有多笨;另一邊是沒有完美、準確地掌握語言,即使是那些在其他方面天賦很高的人也是如此。
