2、ometimes difficult to find the precise meaning of an abbreviation or acronym appearing in that Recommendation 430 is concerned with unit symbols, UNANIMOUSLY RECOMMENDS 1. that with the exception of abbreviations frequently used in telecommunications, abbreviations and acronyms should not be used in
3、 CCIR texts.unless they make the text easier to read, i.e. when an abbreviation may be used several times in the same text; 2. that, with the exception of abbreviations frequently used in telecommunications, the first time an abbreviation is used in a particular text its full meaning should be given
4、, either in the body ofthe text or in a footnote; 3. of each Volume or in a separate fascicle; that an alphabetical list of abbreviations used in the CCIR Volumes should be published either at the end 4. that for the abbreviations most frequently used in telecommunications, the administrations, CCIR
5、 Secretariat and other participants in the work of the CCIR should as far as possible use the abbreviations contained in Appendix I with the meaning indicated therein; 5. , that for abbreviations specific to certain fields, the administrations, CCIR Secretariat and other partici- pants in the work o
