Starting with the second digit in the number , add up all the alternate digit values - 从第二位数起,将奇数位的数值相加。
However , he has managed to develop a mathematical model that explains the distribution of the second digits , putting what might appear to be a statistical oddity on a more solid footing 不过,他应付有方,已经研究出一套数学模型来解释第二位数的分布,将统计上的疑异置于更充裕的分析基础上。
