  1. Thus, the conclusion is drawn : when the diffusion coefficient of cf is invariable and the diffusion time is under a certain range, the beginning corrosion time of the steel in the corner of the rectangular section is independent of the size of rectangular section ; ( 4 ) through the numerical value calculation of rectangular section, the law is found of the influence on modifying coefficient of rectangular section of the thickness of protection layer of concrete and diameter of the steel and the thickness of cf on the surface of concrete, based on which practical calculating method of beginning corrosion time of the steel in the corner of rectangular section is set up

    從而得到結論:在氯離子擴散系數一定的情況下,在一定時間范圍內,矩形截邊角區域鋼筋的初始時間不依賴于矩形截的截尺寸; ( 4 )通過矩形截邊角區域鋼筋初始時間的計算,分析了保護層厚、鋼筋直徑、混凝土氯離子對修正系數的影響,並在此基礎上建立了氯離子侵下矩形截邊角區域鋼筋初始時間的實用計算方法。
  2. Many factors regarding the modifying coefficients of circular and rectangular section are analyzed : ( 1 ) it is theoretically proved that the diffusion coefficient of cl - in concrete is dependent of modifying coefficients ; ( 2 ) through analysis of the results of numerical value calculation, it is discovered that the relation between the modifying coefficients and the thickness of protection layer of concrete is linear, from which the function expression of these two variables is gain ; at the same time, the influence on modifying coefficient of the radius of circular section and the thickness of cl - on the surface of concrete ; based on these, practical calculating method of beginning corrosion time of steel of circular section is set up ; ( 3 ) to rectangular section, the diffusion of cf in concrete is two - dimension diffusion

    討論了影響矩形截以及圓形截修正系數的因素: ( 1 )從理論上證明了氯離子在混凝土中的擴散系數與修正系數無關; ( 2 )通過圓形截數值計算結果的分析,發現圓形截修正系數與保護層厚基本成線性關系,並建立了二者之間的聯系;分析了圓形截半徑、混凝土氯離子對修正系數的影響,從而建立了圓形截鋼筋初始時間的實用計算方法; ( 3 )在矩形截氯離子侵下,混凝土處於二維擴散狀態。本文通過計算分析,證明二維擴散的影響區域從邊角開始向中間逐步擴散,並證明了二維擴散影響區域依賴于氯離子擴散系數與氯離子擴散時間的乘積。

  4. The sense of this work is to gain a further understanding of helium in the two metals. on the diffusion of helium - 3 in two spherical shell samples made of 21 - 6 - 9 type of stainless steel, during the storage of tritium at the pressure of 6. 13mpa for about 4 and 6 years at room temperature and later exposed to air for another 3 and 1 year. first, a calculation based on the analytical and numerical method to the diffusion and decay theories was developed to evaluate the concentration distribution of helium - 3 by tritium diffusion and decay in the samples

    在不鋼氚衰變~ 3he的擴散行為研究中,建立了氚和~ 3he分佈的解析解和數值計算方法,以評估充氚不鋼球形容器壁中氚衰變~ 3he的宏觀分佈,同時還用數值計算方法以求解氚和~ 3he的多步擴散行為;對樣品逐層刻、同時收集釋放的~ 3he進行分析,分別實測了經室溫條件下在6 . 13mpa高壓氚中貯存4年和6年、空氣中存放3年和1年的兩種21 - 6 - 9不鋼球殼樣品內壁中~ 3he分佈;結果明:由於he在金屬中的不可容性, he原子偏聚于不以及內部的局部區域,在整體趨勢上, ~ 3he分佈與計算結果相一致,根據理論計算,兩種21 - 6 - 9不鋼球殼樣品內壁中~ 3he到達的深分別為350 m及500 m 。
