溶液壓頭 的英文怎麼說
中文拼音 [róngyèyātóu]
溶液壓頭
英文
solution head-
This charged fiber can be directed or accelerated by electrical forces and then collected in mats or other useful geometrical forms. the diameters of electrospun fibers are in the range of tens of nanometers to several micrometers. in this paper, polyacrylonitrile ( pan ) nanofibers are made by electrospinning pan / dimethylformamide ( dmf ) and pan / dimethylacetamide ( dmac ) with adjusting the main process parameters including electrostatic voltage ( 20 ~ 50kv ), sprinkler aperture ( 0. 5 ~ 0. 8mm ), collection distance ( 15 ~ 25cm ), solution concentration ( 6 wt % - 14 wt % )
本文主要對聚丙烯腈（ pan ）二甲基甲酰胺（ dmf ） 、 pan二甲基已酰胺（ dmac ）體系進行電紡絲，調節靜電壓（ 20 50kv ） 、噴頭孔徑（ 0 . 5 0 . 8mm ） 、接收距離（ 15 25cm ） 、溶液濃度（ 6wt 14wt ）等過程參數，制得pan納米纖維，纖維平均直徑在200 1000nm ；詳細分析了過程參數對纖維細度、形態等的影響，認為高聚物溶液濃度及靜電壓對纖維細度有決定性影響，其它過程參數如接收距離、噴射孔徑、紡絲溶液溫度、溶液電導率等的調整應以這兩參數為基礎進行。Plastics piping systems - injection - moulded socket fittings for solvent - cemented joints for pressure piping - test method for resistance to a short - term internal hydrostatic pressure
塑料管道系統.壓力管道溶劑膠粘接頭的注射模塑承口連接管件.短期內部液壓壓力的試驗方法Ca2 + ions from the reactants attended to be absorbed in the diffusion dilayer by the so3 - anion. calcium ions could compress the diffusion dilayer and reduce the aggregation number of aot molecular because of the higher charge density. the absorbance of ca2 + ions change of phase diagram of system and water core diameter
反應試劑溶液中的ca ~ （ 2 + ）離子傾向于被吸附在aot極性頭基的- so _ 3 ~ -陰離子附近，壓縮了極性頭基水解產生的擴散雙電層，使得aot分子的聚集體變小，也使得處于束縛狀態的水分子數量減少。
