style="text-indent:25px">環(huán)戊酮有些工程特性量的單位需要特別約定。為了方便地實現(xiàn)實際測量，一般通過環(huán)戊酮建立其約定標度，并在國際建議或者標準文件上說明給定的值。全球認可的用于復(fù)現(xiàn)約定標度固定點的環(huán)戊酮在國際上具有普遍的一致性。這種約定標度的復(fù)現(xiàn)與傳遞主要依賴于復(fù)現(xiàn)標度固定點的環(huán)戊酮和測量方法或測量過程的技術(shù)規(guī)范。在工程量的測量中，環(huán)戊酮的作用不僅是復(fù)現(xiàn)約定的標度，而且還可以用于測量儀器校準或者用作實際樣品測量時的工作標準。約定標度的實例很多。</p><p style="text-indent:25px">參加合作研究的實驗室-應(yīng)具有該環(huán)戊酮定值測量的必備條件，并有一定的技術(shù)**性。每個實驗室可以采用統(tǒng)一的測量方法，也可以選該實驗室確認為為有效的方法。合作實驗室的數(shù)目或**定值測量組數(shù)應(yīng)符合統(tǒng)計學(xué)的要求（當采用同一種方法時，**定值測量組數(shù)一般不少于8個；當采用多種方法時，一般不少于6個）。認定負責機構(gòu)必須對參加比對研究合作定值的實驗室進行質(zhì)量控制，制訂明確的指導(dǎo)原則。如果參與實驗室從本質(zhì)上來說使用的都是同一測量方法來建立特性值。環(huán)戊酮的化學(xué)成分還是比較的復(fù)雜的。</p><div
