While researching the unit statistics, we will, at the first step, make statistics the frequency of the four styles of each commonly used word and classify the different words into sub-types.

在政论语体的个体统计研究中，第一步先统计出政论语体每类中的每个常用词在四种语体中的使用频率，与此同时把各类词按小类归类统计。

In this article, we propose seasonal unit root test statistics based on the Weighted Symmetric estimator and derive representation for limiting distributions of the statistics.

在平均值为零或平均值为已知的季节时间序列模型中，根据加权对称估计量提出季节单位根的检验统计量，并求出此统计量的极限分布的表达式。
