例句與造句

1. The result indicates that when the air content of the concrete changes from 1 to 4 percent , the polarized resistance of the identical flow electricity time increases along with the increment of the air content , the corrosion current density reduces along with the increment of air content , the chloride ion diffusion coefficient reduces with the increment of air content ; when air content changes from 4 to 6 percent , the rule of the change of the polarized resistance and corrosion current density happens to be the opposite , the diffusion coefficient of the chloride ion increases along with the increment of air content ; when the air content is 4 percent , the rust - resisting property of concrete is best , and so is the impermeability of the concrete
   試驗(yàn)結(jié)果表明,混凝土的含氣量在1 . 9 % ~ 4 . 2 %變化時(shí),極化電阻隨含氣量的增大而增大,腐蝕電流密度隨含氣量的增大而減小, cl -擴(kuò)散系數(shù)隨含氣量的增大而減小;當(dāng)含氣量在4 . 2 % ~ 6 . 4 %變化時(shí),極化電阻、腐蝕電流密度和cl -擴(kuò)散系數(shù)的變化規(guī)律則相反;當(dāng)含氣量為4 . 2 %時(shí),抗鋼筋銹蝕性能最佳,抗?jié)B性最好。 cl -擴(kuò)散系數(shù)與鋼筋銹蝕參數(shù)在一定程度上有著良好的相關(guān)性,抗?jié)B性的結(jié)果較好地反映了混凝土中鋼筋銹蝕的程度,可以用cl -擴(kuò)散系數(shù)評(píng)價(jià)引氣混凝土的抗鋼筋銹蝕性能。
