  1. At first, in the process of experiments, it were measured that dry plate pressures drop and point pressures in the flow fields around the single fixed - valve and double fixed - valves under different velocities by using of pitot tube. after that point pressure was transformed to point velocity, two dimensions flow plane of flow fields around fixed - valve were plotted to observe the difference between of the fixed - valve tray with fold edges and the common rectangular fixed - valve tray on the distributions of flow fields and pressures, to provide comparisons and refer - rence for cfd simulation

    在實驗中，利用測速管等儀器對在不同速度下的單閥和雙閥固定閥周圍的流場進行了點壓力測量，然後把點壓力轉化為點速度后繪出固定閥周圍流場的二維流線圖，同時測定了塔板的干板壓降，來考察新型固定閥帶折邊后對流場分佈和壓降的影響，為隨后的數值模擬提供對比和依據。
  2. The paper applies the method of the l - s coupling in the pauli exclusion principle and gives a simple method to determine the atom states of equivalent double electrons through l - s interaction fold line along angle

    摘要採用自旋與軌道相耦的方法，在滿足泡利不相容原理和條件下，給出了快速確定同科雙電子原子自旋與軌道相耦合原子態的一種簡單方法對角折線法，這種方法是對確定同科雙電子自旋軌道耦原子態的又是創新方法。
