  3. Although it is possible that new attempts to estimate the vacuum energy density may yield just the right amount to explain cosmic acceleration, many theorists believe that a correct calculation, incorporating a new symmetry principle, will lead to the conclusion that the energy associated with the quantum vacuum is zero. ( even quantum nothingness weighs nothing

  4. Engine operating conditions cold be changed quickly and are very bad sometimes, such as : from suddenly cranking to driving in winter, acceleration to sudden torque demand. in the light of zero emission vehicles, in order to achieve better hot efficiency, maximum power, higher safety and best emission, engine controls become more and more difficult. automotive engines are typical nonlinear, time - delay, time - varying parameter systems

    汽車發動機使用環境變化大，使用條件有時非常惡劣，從寒冷的冬天突然啟動進入行駛狀態，行駛過程中的突然加速，急劇的扭矩變化等等，在這樣的條件下，為了使其熱效率、輸出功率、行駛性、安全性和排氣清潔性處于最佳狀態，給汽車發動機的控制帶來了極大的困難，特別是零排放汽車排放標準的提出，對發動機控制提出了更高的要求。
  5. On one hand, due to information flow ' s impact on information circulation, the development of information flow leads to avalanche of trade partner, enlargement of international market, rapid acceleration of logistics amount, build - up of transportation safety assurance, enhancement of transportation service quality and helps to accelerate the development of logistics ; on the other, information flow leads to the decrease in personnel flow, shortening of average transportation distance, tendency toward zero inventory and remodel of the traditional logistics

    信息流的發展一方面由於促進了信息的流通，導致了貿易夥伴大量涌現、國際市場擴大，物流量的激增、運輸安全保證的增強、運輸服務質量的提升，從而促進了物流的發展；另一方面，它導致了人員流動的減少，平均運距的縮短，零庫存趨勢，從而沖擊了傳統的物流業。
  6. Scheme of monitor unit of rotational velocity, rotational acceleration and zero rotational velocity

    轉加速度和零轉速度監測單元的設計
  7.
