What’sthedifference?IntroductionofDistributionSystems重点关注注意一下区别和翻译方法Smallindustrialcustomersaresuppliedbyprimaryfeedersatthevoltagelevelof4~20kVfromtheprimarysystem,whichalsosuppliesthedistributiontransformersprovidingsecondaryvoltagesoversingle-phasethree-wirecircuitsforresidentialandcommercialcustomersat120/240V.翻译小型工业用户由一次系统中此电压等级的一次馈线供电。一次系统也经过单相三线电路为居民用电和商业用户提供120/240V二次电压的配电变压器供电。IntroductionofDistributionSystems说明这个句子带有一个由which引导的很长的定语从句，修饰的主体是primarysystem。在定语从句中，providing及后面的内容构成一个现在分词短语，修饰distributiontransformers。词组provide…for…表示：“为…提供…”。为了便于理解，该句子可以拆解为：Smallindustrialcustomersaresuppliedbyprimaryfeedersatthisvoltagelevelfromtheprimarysystem;theprimarysystemalsosuppliesthedistributiontransformers;thedistributiontransformersprovidesecondaryvoltagesforresidentialandcommercialcustomersat120/240Voversingle-phasethree-wirecircuits.IntroductionofDistributionSystems尝试翻译复习术语AsillustratedinFig6.1,theaggregatedloadrepresentedatatransmissionsubstation(BusA)usuallyincludes,inadditiontotheconnectedloaddevices,theeffectsofsubstationstep-downtransformers….负荷load
