本文基于遗传算法思想，采用浮点数矩阵表示编码，在遗传算法的进化过程中加入一定的约束条件等方法，探讨了网络结构的设计和学习。经实例分析，在用于建立大坝安全监控预报模型的前馈神经网络设计中，该方法在满足一定约束条件下，能同时有效地寻找合适的网络结构和相应的参数(神经网络的权值和阈值)，且在精度和速度上都有较大的提高，为实现实时在线分析评价大坝的安全性态提供了有力的技术支持。-Based on the genetic algorithm, using a float matrix coding, Genetic algorithms in the evolutionary process to be bound by certain conditions, to explore the structure of the network design and learning. By analyzing the examples used in the establishment of dam safety monitoring forecasting model of neural network design, The constraint in meeting certain conditions, can effectively find suitable network structure and the corresponding parameters (the neural network weights and thresholds), and the accuracy and speed have improved greatly. To achieve real-time online analysis and evaluation of the safety of the dam states provide strong technical support.

1. PL/0 语言介绍 ●PL/0 程序设计语言是一个较简单的语言，它以赋值语句为基础，构造概念有顺序、条件和重复（循环）三种。PL/0 有子程序概念，包括过程定义（可以嵌套）与调用且有局部变量说明。PL/0语言编译程序采用以语法分析为核心、一遍扫描的编译方法。词法分析和代码生成作为独立的子程序供语法分析程序调用。语法分析的同时，提供了出错报告和出错恢复的功能。在源程序没有错误编译通过的情况下，调用类PCODE解释程序解释执行生成的类PCODE代码。 ●保留字(关键字)：所谓保留字是指在Pascal语言中具有特定的含义。标准Pascal语言中的保留字一共有35个，Turbo Pascal语言一共有51个。下面是Pascal语言的保留字：AND，ARRAY，BEGIN，CASE，CONST，DIV，DO，DOWNTO，ELSE，END，FILE，FOR，FUNTION，GOTO，IF，IN，LABEL，MOD，NIL，NOT，OF，OR，PACKED，PROCEDURE，PROGRAM，RECORD，REPEAT，SET，THEN，TO，TYPE，UNTIL，VAR，WHILE，WITH，EXPORTS，SHR，STRING，ASM，OBJECT，UNIT，CONSTRUCTOR，IMPLEMENTATION，DESTRUCTOR，USES，INHERITED，INLINE，INTERFACE，LIBRARY，XOR，SHL -err
