【求助】求助一小段英语的翻译

这个句子感觉不是很通顺，是整句吗？

可以是意译,不是说还要按一个长句来翻译,可以用几个短句来表达.

为了定义、实现、保存或复现量的单位或一个或多个量值，用作参考的实物量具、测量仪器、参考物质或测量系统
To definite, implement, store or reproduce unites of measure or one or many measurement, material measuring tool、measuring instrument 、reference material or measuring system used as reference
量具和测量仪器的区别在那里？

非常感谢您的帮助!多谢了!

楼主所问其实是GLOSSARY OF ISO METROLOGICAL AND RELATED TERMS AND DEFINITIONS 中一个条目的中译, 其英文原文为:

standard (of measurement): material measure, measuring instrument, reference material or measuring system intended to define, realize, conserve or reproduce a unit of measurement or one or more values of a quantity to serve as a reference

楼主为什么老是拿英文之中译来寻求英译 ? (见http://www.instrument.com.cn/bbs/shtml/20081016/1535064/ 3楼 )

没有仔细检查...........
