  1. Windows and doorsets - wind resistance test

    窗和門組件.風阻力試驗
  2. The analysis of the repeated test data shows the maximum deviation of air drag coefficient is less than 0. 88 % and the deviation of the most surface pressure data is within 1 %, it illustrates the test data is reliable

    重復試驗的數據分析表明，空氣阻力系數數據的最大偏差小於0 . 88 ，絕大部分測壓試驗數據的偏差均在1以內，這說明客車模型風洞試驗數據的精度較高。
  3. A reasonable position of driving nozzle helps to achieve the maximum material flow that also depends on other parameters such as backpressure, properties of conveyed material and driving gas. it is observed that, an increase of convergent section angle is harmful to the pneumatic conveying system, and also influences on the mass flow rate of conveyed material, the distribution of static pressures in injector and the pressure drops of conveying pipe. in addition, within a reasonable scope of air mass rate, increasing the driving jet velocity is more advantageous than enlarging the dimension of driving nozzle

    試驗研究發現，氣體噴嘴位置對氣固噴射器的輸送能力影響最大，氣體噴嘴存在某一最佳位置，而這一最佳位置與背壓、輸送物料特性和輸送風特性相關聯；氣固噴射器的收縮角對其輸送能力、內部靜壓分佈和輸送管阻力特性均有適量影響，收縮角增大對整個輸送系統均不利；在適當的輸送風范圍內，提高氣體噴嘴出口速度比擴大氣體噴嘴尺寸更為有利，但氣體噴嘴出口速度過高會增加氣固噴射器和輸送管內的能量損耗，給輸送帶來不利的影響；系統背壓與氣固噴射器的氣體噴嘴出口速度的選取有關。
  4. Tests for uplift resistance of roof assemblies

    屋面附件的抗風掀動阻力的試驗
  5. Testing of filter sands for air - raid shelter ventilation - determination of flow resistance

    防空洞通風用濾砂試驗.氣流阻力測定
  6. It is a basic need for writing which is included in chinese standards for middle school and the directions for the entrance examination for college. lt has a profound and lasting significance for setting up a new style of writing, telling the truth emotionally and improving the personality accomplishment of youngsters. but the author recognizes that the teaching methods of writing with true feelings in ten linked ways with four steps has only been at the beginning of probing and experimenting. there is a lot of resistance coming from the concept of education, students and society

    最後，本文認為真情實感作文教學是十分必要的，這是《中學語文課程標準》和全國高考「考試說明」中對作文教學的基本要求，對樹立說真話、吐真情的作文新風，提高青少年的人格素養具有深遠的意義。但本文承認「真情實感作文四步十環教學法」僅僅只是處於一實驗摸索階段，還存在來自教育觀念、學生、社會等方方面面的阻力，存在其局限性，還沒有得到教育界廣大同仁的認可和共識，因此，此教學法還有待在今後的教學實踐中進一步完善、發展。
