查询词典 as follows

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。

Wang Xijie, and then raise the "metalinguistic figure" in Chinese language by the way of combining the principle of differentiating metalanguage from object language and delving into metalinguistic cases of daily communications, such as mobile telephone messages in order to specifically analyze the phenomena of positive or negative deviation, potentiality and conspicuity. The dissertation reaches conclusions as follows: It is necessary to keep the principle of differentiating metalanguage and object language, which behaves as the foundation of scientific linguistics and the stereotype of language.

作为方法论原则的元语言理论》一文通过以上各章的研究，得出如下结论：区分元语言和对象语言是语言研究中必须坚持的一条方法论原则，它既是科学的语言学的重要保障，又是语言中的一个"不变量"；元语言是语言学深层次的基础问题，元语言研究有助于更好地揭示语言的本质与机制，并进一步推动语言学各分支学科理论的科学化、形式化和系统化。

Since the motherboard with the soft, hard disk, such as the use of DMA operations between the peripheral, DMA operation of the response process is as follows (AST386 in the floppy disk to DMA as an example): floppy disk drive made by DREQ2 signal to the DMA controller (82C206), and DMA controller to the CPU (80386) issued HRQ signal, CPU end the current bus cycle after HLDA response signal to the DMA controller, DMA controller issued a final response signal DMA to the floppy disk drive DACK2 allow its data into the system bus.

由于主板与软、硬盘等外设之间采用DMA操作，DMA操作的应答过程如下(以AST386中软盘DMA为例)：先由软盘驱动器发DREQ2信号给DMA控制器(82C206)，然后DMA控制器向CPU(80386)发HRQ信号，CPU结束当前总线周期后发响应信号HLDA给DMA控制器，最后DMA控制器发DMA响应信号DACK2给软盘驱动器允许其数据进入系统总线。

Many technical measures have been taken as follows to ensure the safety management: a. operation steps of installing the cross joints are improved to guard against damage on metal sealing and the hanger; b. well logging is applied to gas testing so as to achieve early warning in a scientific way; c. the burning processing unit of QTI3000 is widely used to reduce the bad impact on the environment; d. the articulation of perforating gun is improved to alleviate labor intensity and shorten the perforating time so as to shut down the well promptly in case of any accidents.

The results are as follows: the dwarf mutant A846 pertain to half-dwarf type, which height is about 38.64 cm on average, preponderating over the half-height of the wild-type, the elongation stage of the mutant represent dwarf character, internode elongation patterns of caulis are similarly the sh-type dwarf mutant, in which the first internode shows specific reduction, the elongation of these cells in the elongation zone immediately above the IM was dissimilar to the wild-type, longitudinal length of parenchyma cells were curtate, also the first internode exhibit markedly, which average is under the corresponding internode of the wild-type, the differentiation of the IM of each internodes of stem was similar to wild-type, as well as the number of internodes and the length of sheath of flag leaf.

结果表明：突变体A846平均株高38.64cm，大于野生型株高的一半，为半矮秆类型；其矮生性在拔节期显著表现；主茎茎秆各节间收缩比例不一，穗下第一节间显著缩短，与sh-型突变体类似；茎秆各节间居间分生组织细胞分化正常，由居间分生组织分化的细胞延伸受到不同程度的阻碍；各节间基本组织细胞纵向长度相应缩短，穗下第一节间缩短比例最大，其平均值小于野生型的一半；主茎节间数目与旗叶的叶鞘长类似于野生型。

The general route of the Great Indian Peninsula Railway is as follows:- Leaving Bombay, it passes through Salcette, crossing to the continent opposite Tannah, goes over the chain of the Western Ghauts, runs thence north-east as far as Burhampoor, skirts the nearly independent territory of Bundelcund, ascends to Allahabad, turns thence eastwardly, meeting the Ganges at Benares, then departs from the river a little, and, descending south-eastward by Burdivan and the French town of Chandernagor, has its terminus at Calcutta.
