例如：電鉆、電錘、角磨、切割機、電圓鋸、修邊機等。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
討論了影響矩形截面以及圓形截面修正系數的因素： （ 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 ）通過圓形截面數值計算結果的分析，發現圓形截面修正系數與保護層厚度基本成線性關系，並建立了二者之間的聯系；分析了圓形截面半徑、混凝土表面氯離子濃度對修正系數的影響，從而建立了圓形截面鋼筋初始銹蝕時間的實用計算方法； （ 3 ）在矩形截面氯離子侵蝕下，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。Through repairing the worn parts of four hydropower stations of xinzhuang, zaoqi, suide and qiemo, and taking some comprehensive anti - abrasion measures, such as checking and repairing the runner blade, cutting the head of blade into round shape, adding an apron to the outer edge of blade and increasing a guiding plate in the head of blade, a good effectiveness has been gained so that it increases the output of generating unit and enhances the abrasion resistant capacity
