1、外文翻译标准压电陶瓷材料外文原文Standards for Piezoelectric Ceramic MaterialsThis document details some of the standards related activities for piezoelectric materials, mainly bulk ceramic types. Standards related purely to quartz have been omitted, in order to limit the size of the task. The production of standard

2、s, particularly international ones, is a long and unrewarding business, and that they ever become standards is a tribute to the persistence of a small number of individuals. Consequently the existence or not of a standard in a particular area is not solely because of the need for such a standard, bu

3、t is due to the concerted effort of these individuals. Also because of the need to keep documents current, if years after publication of a standard there is nobody prepared to maintain this document then there is a danger it will be withdrawn or cancelled. This situation is reflected in the piezoele

4、ctric materials standards area, where there are strong groups in Europe (CENELEC) and America (IEEE-UFFC), but some of the most quoted standards have recently been withdrawn ( IEEE 176-1987, IEEE 180-1986, MIL-STD 1376B (SH).Standards organisations with Piezoelectric related standardsCENELEC CENELEC

6、-2. There are two working groups in this committee and it is WG-2 that is producing standards related to piezoelectric materials, under the stewardship of Wanda Wolny. At the time of writing the first three are close to being approved by the various national committees. As with most standards within

These values are provided for design information only.Piezoelectric transducers can have widely differing shapes and may be employed in a range of vibrational modes. Material parameters however, are measured on simple test-pieces, (discs,

13、 rods) using specific geometric anmd electrical boundary conditions. Consequently, the results of the tests provide basic material parameters only and must be used as a guide to the actual properties of manufactured commercial components.prEN 50324-3:2001 Piezoelectric properties of ceramic material
