潛在酸度 的英文怎麼說
中文拼音 [qiánzàisuāndù]
潛在酸度
英文
potential acidity-
2. the results showed that the contents of cach - extractable soil p, and soil test phosphorus ( olsen, bray, mehlich - 3 ) and algae - available p contents ( naoh - extractable soil p ) in the soils correlated significantly with the contents of ortho - p, particulate p and bioavailable p in runoff, respectively, which were feasible to be used as primary indices to evaluate of agriculture p impacting on surface water quality. the results also showed that the relationships between the phosphorus sorption of soil index ( psi ), and the degree of soil saturation with phosphorus ( dpss ) and the contents of ortho - p, particulate p and bioavailable p in runoff reached significant level, respectively
黃壤旱地土壤易解吸磷（ cacl _ 2 - p ） 、土壤有效磷（ olsen - p 、 bray - p 、 mehlich - 3 - p ）或藻類可以利用的土壤磷（ naoh - p ）與地表徑流中顆粒態磷、生物有效性磷和磷酸根態磷之間均存在顯著的相關性，在一定的程度上可用cacl _ 2 - p 、 olsen - p作為指示黃壤旱地地表徑流中磷潛在流失的預警指標，來判斷旱地存在磷素非點源污染的可能性。And through the comprehensive comparisions, along with the dsc analysis of different pcms, it was determined to select the stearic acid ( c18h36o2 ) as the pcm in this paper, provided by beijing chemical reagent company. the stearic acid has an ideal melting point and attractive thermal capacity. all these properties make it an attractive candidate as a potential pcm for heat storage in mid - temperature lhtes systems
並在對多種相變材料做全面比較以及dsc分析的基礎上，確定選用北京化學試劑公司提供的硬脂酸（ c18h36o2 ）作為本文的相變材料（ pcm ） ，其熔點（相變溫度）適中，相變潛熱較大，這些特性使其成為一種中常溫相變儲熱裝置中理想的相變儲熱介質。
