说明：  数据库系统概念中文版，作为大学的核心课程，本书对于自学的同学非常友好，对于里面的伪代码和习题都建议同学自己去尝试。(The Chinese version of the concept of database system, as the core course of university, is very friendly to the students who teach themselves. For the pseudo-code and exercises in this book, students are advised to try it by themselves.)

说明：  用N来表示训练用例（样本）的个数，M表示特征数目。 输入特征数目m，用于确定决策树上一个节点的决策结果；其中m应远小于M。 从N个训练用例（样本）中以有放回抽样的方式，取样N次，形成一个训练集（即bootstrap取样），并用未抽到的用例（样本）作预测，评估其误差。 对于每一个节点，随机选择m个特征，决策树上每个节点的决定都是基于这些特征确定的。根据这m个特征，计算其最佳的分裂方式。 每棵树都会完整成长而不会剪枝，这有可能在建完一棵正常树状分类器后会被采用）。(N is used to represent the number of training cases (samples), and M is used to represent the number of features. The number of input features m is used to determine the decision result of a node in the decision tree, where m should be far less than m. From N training cases (samples), n times are sampled in the way of put back sampling to form a training set (i.e. bootstrap sampling), and the unselected cases (samples) are used to predict and evaluate the error. For each node, m features are randomly selected, and the decision of each node in the decision tree is determined based on these features. According to these m characteristics, the best splitting mode is calculated. Each tree will grow completely without pruning, which may be adopted after building a normal tree classifier).)

采用ANSYS软件的APDL语言编写的两个命令流文件，用于计算含缺陷管道的失效概率，将参数稍作改动，可用于其它结构的可靠性分析(using ANSYS APDL preparation of the two documents order flow, used in the calculation of pipeline containing defects failure probability of parameters minor modifications, can be used for other structural reliability analysis)
