记录密度

During the study, researchers recorded the width of the tree rings of balsam firs. Each ring marked a year of the tree's growth. A narrow ring indicated that the tree's growth had been suppressed that year. The narrow rings appeared only after wolf populations decreased, allowing a greater number of moose to survive and eat more balsam firs.

研究期间，研究人员记录了香脂冷杉树轮的密度，一个树轮表示树生长了一年，有一圈年轮显示出树木在那一年的生长受到了阻碍，根据树的年轮推断出现阻碍的这一年，正是狼群数量减少，鹿的数量大量繁殖的那一年，鹿比平常吃了更多香脂冷杉。

Methods (1) The influence on the rats with non-bacterial prostatitis of 1.5% carrageenin. Rats were divided randomly into the normal control group, the model control group, the Qianliean low-dose group (1.5 g/kg), mid-dose group (3.0 g/kg), high-dose group (6.0 g/kg), with 10 rats in each group. All groups were treated continuously for 7 days, once a day. The model control group was given distilled water, 30mins after the last medication, injects 1.5% carrageenin 0.05ml in each rat's prostate, after 24hs, behead execute the rats and record the white blood cell number and Lecithin density.(2) the influence on the swelling ears of rats.

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。
