decimal multiplication meaning in English

亮度倍增
十进制倍增
十进制乘法

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。
