1. Ultrasonic extraction was used to extract the gypenosides from fresh leaves sample(F), fixed sample(X), baked sample(B), air-dried sample(A) and dry tea sample(D) of Gynostemma pentaphyllum. 用超声法提取绞股蓝鲜叶样、杀青样、烘干样、风干样以及绞股蓝袋泡茶干茶样的总皂甙，并测定其含量。
2. This paper gives the distribution of sample median, sample range, and the negative logarithm of sample product on the basis of function distribution. 应用推导随机（向量）函数分布的有关知识，给出了均匀总体样本的中位数、样本极差及样本分量乘积的负对数的概率分布。
3. The method divides the original data into two parts in term of "close" degree between the original sample and forecast sample: one is initial sample, the other is training sample. 本方法对原有的样品数据根据与待预测样品的关系的“密切”程度分为两个部分，一部分是初始样品，一部分是训练样品。
4. The sample proportion has mean and variance and (3. 7)In Section 14. 1. 4 we show that for , and have covariance(3. 8)The sample proportions have a large-sample multivariate normal distribution. 样品比例有手段和变化 并且（3。7） 在部分14。1。4 我们显示那为， 和有协变性 （3。8） 样品比例有大样品多维分布的正常分配。
5. According to different sources, indoor coverage distribution system can be divided into passive distribution system, active distribution system and fiber optic distribution system. 根据信号源的不同，室内覆盖分布系统可分为无源分布系统、有源分布系统及光纤分布系统三类。
