  1. Researching and analyzing on the test results of the influence of atmospheric parameters on outer insulation discharge voltage and its various emendation methods, it can be concluded that : with the change of relative air density, its humidity ratio h / ? will also change even though the absolute vapor mass ( absolute humidity h ) of the air is constant. consequently, the influence degree of the humidity on the discharge voltage should change, too

    本文通過對以往的大氣參數對外絕緣放電電壓影響的試驗成果及各種校正方法的研究分析認為：隨著相對空氣密度的變化，即使空氣中所含水氣的絕對質量（絕對濕度h ）保持恆定，其比濕h也會變化，必然地，濕度對放電電壓的影響程度也會變化。
  2. 3 ) from the samples saturated completely by air to those saturated completely by brine, the velocities of compressive wave of the rocks increase obviously, with the extent of 11. 73 % ; the velocities of shear wave change little or decrease slightly, with the average of decreasing extent of 1. 21 % for shear wave 1 and 1. 16 % for shear wave 2. the difference of velocity between compressive wave and shear wave makes poisson ' s ratio increase obviously, with the average extent of 87. 25 %

    3 ）從完全飽和氣到完全飽和水，珠江口盆地第三系砂巖、粉砂巖、碳酸鹽巖及其過渡性巖石類型的縱波速度是顯著增加的，平均增加幅度為11 . 73 ；橫波速度變化很小，或略有降低，橫波1平均降低幅度為1 . 21 ，橫波2平均降低幅度為1 . 16 ；縱橫波速度的這種差異變化導致泊松比顯著增加，平均增加幅度為87 . 25 。
  3. This paper also analyzes the ash wear mechanism, and then does the effects of low temperature economizer wear five factors : the first is the smoke corridor caused by wear mechanism, the second is the impact on the wall material, and the third is that of flying ash concentration, the fourth of the excess air ratio, and the fifth is the change in the composition of the gas to wear the impact

    分析了飛灰磨損的機理，然後分析了影響低溫省煤器磨損的5種因素，一是煙氣走廊引起磨損的機理；二是管壁材料的影響；三是飛灰濃度的影響；四是過量空氣系數的影響；五是煙氣成分的變化對磨損的影響。
  4. Vegetable soil was treated with the 20ml / s mixed gas of hydrogen and air ( the ratio = 1 : 9 ) by the man - made analog equipment that can release hydrogen just like nodules, at the same time, control was made that treated with 20ml / s air flow. after three month, analysis the soil. which nutrition and how it changed were try to find. result indicated that nitrogen was changed but phosphorus and potassium had no evident change

    採用人工模擬根瘤放氫裝置，一系列相關指標的變化，有效養分發生了何種變化及其可能機理。結果表明，土壤經氫處理后對氮素及其相關因子表現出較大影響，而對磷素和鉀素及其相關因子無明顯改變。
