The optimization methods of database SQL query were studied and some available query optimization Methods were given out as follows: The incompatible data type should avoid to be used; More redundancy search parameters should be given as join condition in join query; In some condition, the number of note hitted to target was estimated by optimizing implement using the average density; Some other maths operating symbol should avoid to be used as condition parameters in WHERE clause; Some operating symbol and its sentence should avoid to be used also; When the cluster function was used,the WHERE clause should be paied attention to more,and so on.

作者单位：（重庆工学院商贸信息学院，重庆 400050）摘要：数据库SQL查询语句的优化，须注意：避免使用不兼容数据类型；连接查询中应多给连接条件提供一些冗余的搜索参数；某种条件下优化器只能使用其平均密度以估计命中的记录数；避免对WHERE子句中条件参数使用其它数学操作符；避免使用某些操作符及相应语句；聚簇函数的使用应注意WHERE子句。

A module receiving knowledge links from symbols on other modules can be commanded to 'contract,' confabulate, yielding a single active conclusion symbol, that symbol having the highest level of summed incoming knowledge link excitations.

得到的模件知识符号的连接在其他模件上可能对'签合同，' confabulate，产生单个积极结论符号，那个符号有合计的进来的知识连接激励的最高的水平。

The factors which should be considered in BP training are found and program is compiled by C++ Builder. Good agreements are obtained by training 30 runs of lower concentration, middle concentration and hyproconcentration flow. The conjunctional functions are memoried and used to pr...

找出了进行BP神经网络训练时应考虑的水沙要素，采用C ++Builder语言编制的程序，对 3 0组高、中、低含沙量的水槽试验资料进行训练，发现训练值与实测值符合较好，说明得到的连接权能反映实际情况；用该连接权对 4组试验数据进行了预测，预测结果与实测值相差较小，表明用BP神经网络方法确定挟沙能力的可行性。
