  2. The key to financial reform in rural china still lies in relaxing the barriers to entry and exit, allowing financial transactions at the bottom to develop into the requisite superstructure for more and bigger markets, and enabling the exogenous supply of rural financial system by the state to change to the spontaneous and endogenous demand for rural financial reform at the bottom, thus forming a stable structure of rural financial system

    由此，中國農村金融改革的要旨仍在於放開市場的進入和退出壁壘，讓底層的金融交易行為發展出更多更大的市場所需的上層組織，使得國家對農村金融制度的外在供給讓位於底層自發性的對農村金融制度變革的內在需求，以形成一個穩定的農村金融制度結構。
  3. For example, when magnetic material being pressed, magnetic domain, direction and strength of spontaneous magnetization will vary. this phenomenon is called effect of pressing magnet. whichever rearrangement of magnetic domain or direction change of spontaneous magnetization will induces extra shape change of material

    如對鐵磁材料施加應力時，往往會導致磁疇、自發磁化方向和強度發生變化，這一現象稱之為壓磁效應，由於得益於壓磁效應的作用，不論是磁疇重新排列還是自發磁化方向發生變化都會引起材料額外的形變，因此在一定應力的作用下鐵磁材料能產生非彈性變形。
  4. When the stress at the tip of crack is inflicted on the m - type ferrite particle dispersed in matrix as a second particle, not only the toughness of composites will be pro ved because of the non - elastic area produced by the particle but also the strength change of magnetic field and the stress distribution in the structural ceramics will be detected by the strength of spontaneous magnetization varying while magnetic materials being pressed or drawn

    這是因為當結構陶瓷中裂紋尖端的應力作用在彌散於基體內的鐵磁體二相粒子上時，鐵磁粒子不僅在裂紋尖端周圍產生的非彈性區域使復合材料的韌性提高；而且還能利用鐵磁材料在外應力作用下自發磁化強度發生變化的性質，通過測量復合材料在應力作用下磁場強度的變化，探測出結構陶瓷中的應力分佈情況。
  5. Optical microcavity arouses great interest in condensed state physics. it can change characters of spontaneous emission, such as spectral full width at half - maximum, light intensity at peak and so on

    光學微腔是目前凝聚態物理的研究熱點，它能夠改變自發發射的特性（譜線寬度、發光強度等） 。
  6. Obvious change of wart or mole enlarged, change in color, or spontaneous bleeding

    疣或痣出現明顯變化增大出血或顏色改變
  7. So magnetic material will produce non - elastic shape change when it is pressed or drawn. additionally the strength changes of spontaneous magnetization benefits to detect distribution of stress

    另外，作用在鐵磁材料上的應力能使其自發磁化強度發生變化，為檢測材料中的應力分佈提供了依據。
  8. Therefore, by adopting new institutionalism ' s theory of institution change and institution innovation, we present in chapter 2 a new explanation to the entry of nses of china after reform. this chapter points out that the entry of nses is the result of a series of spontaneous institution innovation activities which have been initialized by certain entities aiming at getting the potential profits of institution innovation

    為此我們在第二章中利用新制度經濟學的制度變遷和制度創新理論給出了一個非國有企業進入的分析框架，指出非國有企業的進入是一群行動主體為了獲取制度不均衡所出現的潛在獲利機會而自發進行的制度創新活動。
  9. At the same time, it will change the passiveness in the process of the students " studying ; make the students study more in more spontaneous and creative mood

    研究性學習和學科教學相輔相成，它改變了學科教學中學生被動接受的學習方式，並充分發揮學生的主體性和創造性。
  10. It takes the competitive ability of agricultural product in market as the representation, reflects one kind of relative synthesis productivity that faces spontaneous change and market shift

    它以農產品在市場上的競爭能力為表象，反映的是農業生產應對自然變化、應對市場變化從而保持的一種相對的綜合生產能力。
  11. Obvious change of wart or mole ( enlarged, change in color, or spontaneous bleeding )

    疣或痣出現明顯變化（增大、出血或顏色改變）
