反之,神经酰胺也抑制了海藻糖在干燥过程中结晶,从而延缓了水分挥发. 此外,在海藻糖的存在下,冷冻干燥的神经酰胺乳液样品加热至105 ℃再降至室温,形成了皮肤中广泛存在的正交晶相和液晶相共存的结构,很好地模拟了皮肤细胞间脂层的相结构. 发现海藻糖代替了角质层中的其它成分,保护神经酰胺分子以真实皮肤中的方式排列.","authors":[{"authorName":"王寅宁","id":"1169ccc2-352b-4ae2-a113-4cf1cdd5c39c","originalAuthorName":"王寅宁"},{"authorName":"赵佰金","id":"bfcbdac7-c791-4bbb-8655-236130e6ae13","originalAuthorName":"赵佰金"},{"authorName":"李良彬","id":"056972a0-f830-4664-a0b7-82ce8fe4709a","originalAuthorName":"李良彬"}],"doi":"10.3724/SP.J.1095.2010.90878","fpage":"1149","id":"0a43a241-b07b-45b6-9f0b-1d780270fd74","issue":"10","journal":{"abbrevTitle":"YYHX","coverImgSrc":"journal/img/cover/YYHX.jpg","id":"73","issnPpub":"1000-0518","publisherId":"YYHX","title":"应用化学"},"keywords":[{"id":"040cc207-d5be-4dca-bd3d-52911c9f3cf5","keyword":"海藻糖","originalKeyword":"海藻糖"},{"id":"fb555bb4-2d7b-4d25-80e0-691dcfc4702b","keyword":"神经酰胺","originalKeyword":"神经酰胺"},{"id":"d03ab235-599e-49e3-9557-22249f1b2b8b","keyword":"<span

style=\"color:red\">散射</span>(2D-SAXS)方法,对PAN基炭纤维全部方位角进行微孔结构的研究.样品选取自制炭纤维MHS及日本东丽公司T300,T800产品.结果表明:MHS炭纤维微孔尺寸介于T300与T800之间,长径比t值小于T300和T800.T300中较小微孔(<9.1 nm)和较大微孔(>15.4nm)的含量大于MHS,T800含有大量的微孔短轴小于2nm的小尺寸微孔.MHS炭纤维的界面复杂程度较T300大,而小于T800.炭纤维内部存在由微孔<span style=\"color:red\">散射</span>导致的密度波动,其波动振幅F值和波动密度n值按MHS、T300和T800依次递减;电子密度波动越小,表明微孔结构越规整,T800的孔结构最规整.炭纤维内各个取向上均有一定结构的微孔分布,但总体上呈现沿纤维轴方向的定向排列.","authors":[{"authorName":"盛毅","id":"466eb6e9-a151-4180-aac6-ac2422c2f1b2","originalAuthorName":"盛毅"},{"authorName":"张彩红","id":"4e880523-b67a-4817-932c-a8899270521e","originalAuthorName":"张彩红"},{"authorName":"徐耀","id":"86fec243-dc33-474d-88ca-fa8cc8118a90","originalAuthorName":"徐耀"},{"authorName":"吕春祥","id":"747e9138-1afd-49e5-9117-5ac464db2dc7","originalAuthorName":"吕春祥"},{"authorName":"吴刚平","id":"d3a20ca8-b222-4559-b100-691654048a81","originalAuthorName":"吴刚平"},{"authorName":"吴忠华","id":"f9d506c6-cdcb-4460-9cf2-6caf2a6462e8","originalAuthorName":"吴忠华"},{"authorName":"李志宏","id":"37a02f1f-4bea-4ff8-b1c9-0bfe207eb7cf","originalAuthorName":"李志宏"}],"doi":"","fpage":"270","id":"3ac9efd7-3b66-4ba3-bf55-3a64ec68ea1b","issue":"3","journal":{"abbrevTitle":"XXTCL","coverImgSrc":"journal/img/cover/XXTCL.jpg","id":"70","issnPpub":"1007-8827","publisherId":"XXTCL","title":"新型炭材料"},"keywords":[{"id":"580a4034-adb0-4ac8-910b-b26fbc489cfe","keyword":"SAXS","originalKeyword":"SAXS"},{"id":"020628ad-21a4-4735-8e28-c6cd8949ec7a","keyword":"炭纤维","originalKeyword":"炭纤维"},{"id":"c898dcaa-6398-4e35-8a5a-ea755b07cad0","keyword":"孔结构","originalKeyword":"孔结构"},{"id":"7db5b664-0955-4a51-a5aa-ab9b00c27d28","keyword":"分形维数","originalKeyword":"分形维数"},{"id":"05b7bb56-74f2-45bc-b784-dd8f73730853","keyword":"密度波动","originalKeyword":"密度波动"}],"language":"zh","publisherId":"xxtcl200903009","title":"二维小角<span
