外部数据存储 meaning in English
external data storage
Examples
- Unbound mode can be particularly useful for static , read - only data , or when you want to provide your own code that interacts with an external data store
未绑定模式对于静态只读数据非常有用，或者当您希望提供自己的与外部数据存储区进行交互的代码，该模式同样非常有用。 - You can use similar i o statements to access different types of external data stores , whether those data stores are files , relational databases , or message queues
您可以使用类似的i / o语句来访问不同类型的外部数据存储，而不用关心那些数据存储是文件、关系数据库，还是消息队列。 - You can focus on the business problem your code is addressing rather than on the technical complexities of cics , mqseries , and sql ; for example , you can use similar i o statements to access different types of external data stores
您可以集中精力考虑代码所要解决的业务问题上，而不必疲于应付cics 、 mqseries和sql之类复杂的技术问题；例如，您可以用相似的i / o语句来访问不同类型的外部数据存储。 - In the digital ultrasonic flaw detectors , backward - wave signal is sampled and changed through the highspeed a / d converter , and we ' ll get a large number of datas . because datas are not all be used to draw testing curve , they must be compacted . lt is necessary to compress so much datas , so data - compaction instrument must be designed and used . here introduces the principle of data - compaction instrument , and designs a exclusive instrument using isp which may change compression point and automatically provide 1024 consecutive addresses of outside data storage unit
在数字化超声波探伤中，回波信号经高速a d采样变换后，会得到大量的采集数据。但在探伤曲线的描绘中并不是用到所有数据，因此要对这些数据进行压缩处理，这就需要用到数据压缩器，这里介绍了一种应用在线可编程技术及器件实现对大量采样数据进行快速压缩的方法，并设计了一种新型的专用isp数据压缩器，该压缩器具有压缩点数可调，可自动提供1024个连续的外部数据存储单元的地址等特点。
