走马楼吴简中保存的仓库收支米、线的记录,包含确切的时间、地点、人物、事项等具体内容,对其进行分类、统计,工作量非常大,但统计结果可以做到比较准确。吴简中还有大量户籍类记录,所属的具体年份很难判断,每条记录所属的乡、里也不易知晓。对于这类资料,利用代数方法所推导的统计方法,以若干年为一个时段,计算这一时段人口状况平均值,是有其合理性的。 The records of warehouse receipts and expenditures, including the exact time, place, people and events, contained in the records of Wuzhu floor and Wuzhang floor are categorized and statistically calculated. The workload is very large, but the statistical results can be relatively accurate. There is also a large number of Wu Jianzhong household records, the specific year is difficult to judge the specific, each record belongs to the township, is not easy to know. For such data, using the statistical methods derived from algebraic methods, it is reasonable to calculate the average of the population status for this period over a period of several years.
