查询词典 sequential compactness

For example, if the search is for points stored in a random sequential file, all records in the file must be queried to ascertain whether the desired points have been located.

在连续记录的档案中搜寻资料是很费时的，例如寻找纪录在某个连续档案中的点位，不管是否找到需要的点位，档案中的所有纪录都会被要求查询，因此未整理的档案只建议储存较小量的资料。

Several interrelating networks of different types being a information description object, a dataset can be designed to include all kinds of observation data, observation instrument, adjustment computation data, file data and descriptive data of a control network, stored in the form of sequential file.

以多个相互关联的不同类型控制网为信息表示对象，将控制网的各种观测数据、观测仪器、平差计算数据、文档数据和描述性数据设计在一个数据集中，并以顺序文件形式存储。

Undoing a block does not require an expensive sequential scan of a log file. It is simply a matter of locating the right version of the data block within the database.

还原数据块时无需执行代价高昂的日志文件顺序扫描操作，而只需在数据库内确定数据块的正确版本即可。

Discrete control points being a information description object, a datasheet can be designed to include all kinds of coordinate data, coordinate explanation data, station occupation description data, file data of a single point, stored in the form of sequential file.

以离散的点位为信息表示对象，将一个点的各种坐标数据、坐标说明数据、测站描述数据、文件数据等设计在一张数据单中，并以顺序文件形式存储。

The procedure will internally be very different depending on how the table is stored (sequential array or file, hash table, binary or B-Tree etc.).

对于不同的表储存结构(顺序数组或文件，哈希表，二进制或B树等等。)，程序在内部是不同的。

The storage capacity of these media is virtually unlimited,and the storage cost is very low.but before the CPU can gain access to a particular record,a computer operator must locate the sequential file and load it on an input device.

这些介质的存储容量实际上是无上限的，而且其成本非常低。

This paper discusses the organizing principle of knowledge library in expert system and suggest that the Sequential File, Index File, Multichain File, Backcomposing File, Hash File, etc can be adopted to organize knowledge library and the corresponding program is designed in the Prolog Language.

论述了专家系统中知识库的组织原则，对在计算机上如何实现知识库的物理组织问题，提出可以采用顺序文件、索引文件、多重链接表文件、倒排文件及散列文件等方法来组织知识库。

Propose a real-time expanding scheme for UNIX System V. Propose and design a new time-and-priority driven process scheduling strategy, which can unify real-time process, kernel process and time-sharing process for scheduling. Design a new concurrence control strategy for UNIX, which can support priority inheritance. Add the sequential file operations to the UNIX random file system and design a high accuracy clock timer.

对UNIX System V提出了一套实时扩充方案，提出并设计了一种新的基于时间和优先数两者驱动的进程调度策略，对实时进程、核心进程和分时进程统一调度；设计了一种新的允许继承进程优先数的并发控制策略；在UNIX随机文件系统的基础之上扩充了连续文件操作；并且设计了高精度的时钟处理程序。
