All measurement points shall be specified, so that they are uniquely identified. In case of particular difficulties, measurements can be supplemented by detailed theoretical predictions. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
