  2. By comparing the dry plate pressures drop and distributions of velocities simulated on single valve with those of double valves, it was found that there was intense turbulence in the flow fields around fixed - valve, there were eddy areas between valve side orifices and tray wall, there were eddies above the valves too, these led to the complex behaviors of gas perforating valve, these had a great effect on the gas - liquid mass transfer process. at the same time, in order to prevent the disadvantageous effect of gas between one valve with another on the gas - liquid mass transfer, it was very effective to change the fields of gas perforating valve by folding the edges of valve

    通過對數值模擬得出的單閥和雙閥塔板的干板壓降及流場速度分佈分析對比后發現，固定閥周圍流場存在較強的湍動，閥側孔與塔板壁面區域以及閥體的上方空間存在明顯的渦流區，使氣體穿閥后的行為變得復雜，並對氣液傳質過程產生重大影響；模擬結果表明，為防止和削弱固定閥間的對沖造成的「死區」對傳質帶來的不利影響，通過折邊來改變氣體的氣路是非常有效的，模擬值與實驗值基本得到吻合。
  3. Using extremum statistical method to predict pit corrosion sizes of the pipeline in service and further to evaluate the residual strength of the pipeline has a great significance for controlling accidents of corrosive perforations, guiding pipeline rehabilitation and replacement as well as prolonging service life of pipeline

    長輸管道的腐蝕類型多為均勻腐蝕或點腐蝕，採用極值統計方法對在役管道的點蝕尺寸進行預測，進而評價管道的剩餘強度，對于控制管道的腐蝕穿孔事故、指導管道的修復更換、延長管道的使用壽命具有重要意義。
