对墨西哥湾北部水深约540m的上陆坡GC185区(GC—F样品)和水深约2200m的下陆坡AC645区(AC—E样品)冷泉碳酸盐岩中的脂肪酸及其单体化合物的δ^13C进行了分析.在AC-E和GC-F冷泉碳酸盐岩样品中检测到了30多种脂肪酸化合物,均以主峰碳为C16的低碳数(〈C20)脂肪酸为主,具偶碳优势,主要包括正构脂肪酸、异构(i-)/反异构(ai-)脂肪酸以及带支链的(iso/anteiso)奇碳数脂肪酸.其中n-c12:0,n-C13:0,i—C14:0和n—C14:0具有明显偏低的δ^13C值(

英國的「能源與氣候變遷部」(UK Department of Energy and Climate Change, 2010)指出,一般住家在採行能源效率改善措施時,也面對多種障礙,包括資訊不足、不正確的價格信息、融資不易、契約問題、技術不足,以及不確定性等問題。鑒於「低碳永續家園」所涵蓋的範圍極廣,所涉業務領域甚多,所面臨的問題及障礙更是不一而足。因此,本文首先從政府財政能力、現有融資問題、及住家的困境等層面,分析當前推動低碳永續家園的障礙。其次,則以英國為例,說明其所推動的各項節能減碳政策及融資機制,
