• 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
  试验结果表明,混凝土的含气量在1 . 9 % ~ 4 . 2 %变化时,极化电阻随含气量的增大而增大,腐蚀电流密度随含气量的增大而减小, cl -扩散系数随含气量的增大而减小;当含气量在4 . 2 % ~ 6 . 4 %变化时,极化电阻、腐蚀电流密度和cl -扩散系数的变化规律则相反;当含气量为4 . 2 %时,抗钢筋锈蚀性能最佳,抗渗性最好。 cl -扩散系数与钢筋锈蚀参数在一定程度上有着良好的相关性,抗渗性的结果较好地反映了混凝土中钢筋锈蚀的程度,可以用cl -扩散系数评价引气混凝土的抗钢筋锈蚀性能。
• When calculate the correlation function of binary array pairs , using the boolean calculation instead of the decimal multiplication , using the method of count the number of 1 in binary integer to calculate the correlation function of binary array pairs , the speed of searching is obviously improved by these methods . by the algorithm introduced in this paper , the constant weight and normative perfect binary array pairs whose volume from 4 to 28 and quasi - perfect binary array pairs whose volume from 2 to 24 were searched and gi ved the new result
  此外，采用二进制整数来表示阵列，通过对整数的逻辑运算来实现阵列偶的移位变换、完全采样变换等运算；在计算二进阵列偶的相关函数时，用整数的逻辑运算代替十进制中的乘法运算，并用计算二进制整数中1的个数的方法来计算二进阵列偶的相关函数，以上方法的采用明显地提高了搜索速度。利用上述算法，对体积为4 28的等重规范型最佳二进阵列偶和体积为2 24的准最佳二进阵列偶进行了搜索，并给出了新的结果。
