positive acceleration 中文意思是什麼

positive acceleration 解釋
正加速度
  • positive : adj 1 確實的，明確的；確定的；無條件的 （opp qualified implied inferential）; 絕對的，無疑問的，...
  • acceleration : n. 1. 加速；促進。2. 【物理學】加速度；變速。3. 【教育】加速升級。
  1. The acceleration is positive if the speed is increased, negative if speed is decreased

    速度增加的加速度為正加速度，速度減少的加速度為負加速度。
  2. When a swimmer slows and then finally applies forces there are stages of slowing down ( the correct term is negative acceleration not deceleration ) and speeding up ( the correct term is positive acceleration not acceleration )

    當游泳運動員慢下來然後增加力量以求得繼續前進時會有不同的階段，這就是減速階段（正確用語是負加速度而非減速）和加速階段（正確用語是正加速度而非加速） 。
  3. Extreme negative and positive acceleration phases are not a characteristic of swimmers who must be efficient ( e. g., 200 m plus ) who usually demonstrate high rates, almost continuous propulsive force production, and minimum periods of time in long " sculling boat " positions

    最終的負加速度和正加速度階段並不是一個有效率的（例如200多米）和經常呈現高效的，能夠持續產生推進力和盡可能減少處于長的皮劃艇位置的時間游泳運動員的特徵。
  4. In the course of time positive and negative acceleration impulses tend to cancel one another.

    在長時間中，正向和反向加速度沖擊有互相抵消的趨勢。
  5. The acceleration of the urbanization process of the daur people is a reflection of the enhancement of national quality, a contribution to the development of each task and cultural variety in cities and brings about positive influence on further improving cultural educational level, enhancing the life quality of physical and cultural life and developing intelligence

    達斡爾族人口城市化進程的加快，是民族素質提高的表現，也為城市各項事業的發展和文化多樣性作出了貢獻，對于達斡爾族進一步提高文化教育水平，提高物質文化生活質量，發揮聰明才智都產生了積極的影響。
  6. The findings show that ( 1 ) most acceleration mechanisms would facilitate npd speed effectively except the external sourcing of knowledge ; ( 2 ) internal corporate - level acceleration mechanism has a positive direct and indirect influences on project success, while two acceleration mechanisms of internal project - level and external sourcing of knowledge only have indirect effects ; ( 3 ) the result identifies a significant positive relationship between npd speed and quality as well as a significant negative relationship between npd speed and cost

    主要研究發現為： （ 1 ）除了外部技術來源加速機制一項外，其他加速機制都能有效加速新產品開發速度； （ 2 ）內部公司層級加速機制對專案成功有正向的直接效果與間接效果，而內部計畫層級加速機制與外部技術來源加速機制兩項則僅有間接效果； （ 3 ）新產品開發速度愈快，愈能降低開發成本以及提升開發品質。
  7. Positive acceleration phase

    正性加速期
  8. All these indicate the transformation of scientific and technological system from state - owned to enterprise - owned, from high intensive to harmony. in the end, from the viewpoint of the integration of science & technology and economy, the thesis demonstrates the positive acceleration effect of the scientific and technological system transformation on the development of economy

    這些特徵昭示著我國科技體制從政府型科技體制向企業主體型科技體制的變遷，從高度集中型科技體制向集中協調型科技體制的變遷。最後，論文從科技與經濟一體化發展的角度，論證了我國科技體制的變遷對經濟發展的促進，肯定了這種變遷趨勢對促進科技成為經濟增長和經濟發展的關鍵要素的意義。
  9. Acceleration : a change in velocity with respect to time. values are either positive or negative with standard orientation

    加速度：速度相對時間的變化。加速度值根據確定的方向而為正或者負。
