Methane and nitrous oxideare taken into account by converting them into “ carbon - dioxide equivalent ” emissions using conversion factors provided by the intergovernmental panel onclimate change 人们已经在考虑将沼气与一氧化二氮气体使用由气候变化政府专门小组提供的转换因子转换为二氧化碳的对等物。
If you are one of those trivia buffs who keeps all the conversion factors in your head , you may have noticed that i accidentally told you that the conversion factor from meters to yards was 倘若您是个细心的人，把所有转换因子都记在脑海里，您可能注意到了，我曾经告诉过您，从米到码（ metertoyard ）的转换因子是
The new series has year 2000 as the base year . in the new series , indices for periods prior to 2000 are obtained by re - scaling the previously published series , which has 1990 as the base year , using a conversion factor derived from the levels of the old and new series in the overlapping period of 2000 二零零零年以前的新系列指数是将以往发表的旧系列指数(以一九九零年为基期)按比例换算得来，所用的换算因子是根据新旧系列在二零零零年重叠期间的数值而计算的。
The absorbed doses are obtained with a uniform state ion chamber that is formed with liftld cavity and lif wall and designed by ourselves . the key problem , the dose to fluence conversion factor of the photon with single energy from 0 . 1 mev to 12mev , has been solved by simulating with monte carlo code system egs4 用m - c方法计算了固体电离室对0 . 1mev 12mev的单能光子的单位光子注量? lif吸收剂量的转换因子，从而解决了由高能光子吸收剂量实测值转换成光子注量时所面临的困难问题。
