  1. The advantage and disadvantage of measurement of propeller - induced pressure by using different equipment is discussed. the method to obtain self - propulsion point for full scale in depressurized towing tank is studied. the measurements of pressure of two propeller models are carried out, the results of the measurement agree with those obtained by cavitation tunnel very well, which proves this measurement is successful, and the theoretical prediction is verified too

    比較了不同測試設備用於螺旋槳脈動壓力測試的優缺點，探討了在減壓拖曳水池中實現實船自航點的方法，並進行了兩只螺旋槳模型的脈動壓力測試，經與空泡水洞中脈動壓力的測試結果進行比較，說明該項測試是成功的，同時也對脈動壓力的理論預報結果做了驗證。
  2. Rotation - cavitation mechanism was outlined based on the experiment results and the essential conditions for the occurrence of auxetic properties in polyolefin blends were concluded as followed : firstly there must be at least two phases, the matrix can be soft materials which were able to be networks when being stretched, as well as suitable consistence must be provided between two phases. fracture stress work measurement was optioned to characterize the force between two phases. finally, the auxtic property repeatability of the blends was measured and the fact that the auxetic property could only occur in the elastic range was certificated by the result that only the specimens which were stretched for 5s, 10s had repeatability after being retained for 1 months

    實驗工作的最後一部分研究了體系負泊松比效應的可重復性，選取穩定的負泊松比共混體系在測試數據採集時間為55 、 105 、 155 、 205條件下進行測試，將樣條放置l天、 10天、 30天進行測試，測試結果表明，在5s 、 105條件下測試的試樣在放置一個月後泊松比測試結果具有可重復性，證實了體系的負泊松比現象發生在材料的彈性形變范圍內。
  3. A kind of measurement was developed to measure the air concentration of water and the result showed the possibility of entrained air existing near the wall of drop shaft. that is to say, the wall of drop shaft may be protected by entrained air from cavitation damage to some extent

    本文設計了一種適用於近壁區水流摻氣濃度測量的方法，對空腔段水流摻氣濃度進行初步測量，發現井壁附近水流存在摻氣的可能，這對改善水流空化條件能起到積極作用。
