Composition Structure Many good compositions of academic writing (e.g. report, an essay, an assignment, a project) have their organizational structure or their ways in which the different parts are linked together. The following general plan for three paragraph composition will help to control the overall structure of your writing

微生物生物量碳测定方法 (1)试剂配制: 0.5MK2SO4溶液:称取K2SO4174.33g溶解于蒸馏水中,搅拌溶解,(可加热)定容 至2L 去乙醇氯仿的配制:在通风柜中,量取100毫升氯仿至500毫升的分液漏斗中,加 入200毫升的蒸馏水,加塞,上下振荡10下,打开塞子放气,而后加塞再振荡10下, 反复3次,将分液漏斗置于铁架台上,静止溶液分层,打开分液漏斗下端的阀,将下层 溶液(氯仿)放入200毫升的烧杯中,将剩余的溶液倒入水槽,用自来水冲洗。再将烧 杯中的氯仿倒入分液漏斗中,反复3次
