  1. China has entered wto, that means the customs duties as well as the non - tariff barrier must be eliminated, and this causes " the major industry " or " the extra large type of enterprise " in domestic in the absolute superiority originally turned into relatively " the small and medium - sized enterprises " ; and challenge and competition caused by multinational corporations is in our own country ; because enterprise ' s technical level and idea of management in our country is backward relatively, the difference of strength phase is disparate with the multinational corporation in the competitive process, therefore, strategy management to small and medium - sized enterprise ' s research and implementation is on watershed in our country

    中國「入世」后，意味著那些關稅以及非關稅壁壘必須消除，大量的跨國公司則趁機大舉進入中國，搶灘后利用其資金、技術、管理、人力等優勢迅速瓜分市場，這就使得原先在國內處于絕對優勢的「大型企業」或「特大型企業」變成了相對的「中小型企業」 ，並在家門口直接遭遇跨國公司短兵相接的挑戰和競爭;由於我國企業的技術水平和管理理念與那些跨國公司相比，相對比較落後，在與跨國公司的競爭過程中實力相差懸殊，所以對我國中小企業戰略管理的研究和實施就顯得更加意義重大。

  3. In chapter one, we propose a new mixed method called characteristics mixed finite element method for a convection - dominated diffusion problems with small parameter e : we handle the convection part whth backward difference scheme along the characteristics, obtain much smaller time - trunction errors and avoid numerical dispersion on the front of the peak curve of the flow : we use a lowest order mixed finite element method to deal with the diffusion part, so this scheme can approximate the unknow function and its following vector with high accuracy at the same time

    第一章中我們對小參數對流占優擴散問題提出了新的數值方法? ?特徵混合有限元方法，即對方程的對流部分採用沿特徵線的後退差分格式求解，以保證較小的截斷誤差限並避免了在流動的鋒線前沿數值彌散現象的出現；對流動的擴散部分採用最低次混合元方法求解，以保證格式對未知函數及伴隨向量的同時高精度逼近。由於該方法中檢驗函數可取分片常數，此格式在某種意義上具有局部守恆性質。
  4. However, their research is still confined within one single relevant factor, and very little comprehensive study has a negative influence on an overall understanding of the factors influencing trait anxiety. furthermore, the statistic methods used by them are backward, and they are confined to relevance analysis, difference test and regression analysis. consequently, their research fail in demonstrating the concrete mechanism of the factors influencing trait anxiety, and in defining the relative importance of the relevant factors during the process of the form of trait anxiety

    但現有的研究主要是針對單一的影響因素而展開，綜合性研究還很少，從而限制了對特質焦慮影響因素的宏觀理解，而且大多數研究的統計方法相當落後，僅停留在一般的相關分析、差異檢驗和回歸分析方面，因而無法揭示各種因素對特質焦慮影響的具體機制，也無法明確各種影響因素在特質焦慮形成中的相對重要性。
  5. But as a matter of fact, for the undeveloped, in a passive way, executing import - substituted strategy and attracting foreign capitals is essentially accepting the backward industries that the developed abandoned. to a certain degree, it is beneficial for the undeveloped to boost new tech and uplift traditional sectors, but it cannot shake off the inherent grade ' s difference

    但是事實上，欠發達國家實行的「進口替代」與「引進外資」戰略，其實質是被動接受發達國家所轉移的落後產業，它對欠發達國家新技術產業的發展和傳統產業的提升雖然具有一定的作用，但不能消除固有的產業級差。
