Zwitterionic surfactants whose hydrophilic polar heads carry both positive and negative charges, are a kind of important surfactants [1]. In this paper, we investigated two types of zwitterionic surfactants,amino-acid surfactants and dodecyl dimethyl(3-sulfopropyl)-ammonium, which all are ***-acid surfactants are composed of polar amino acid or oligopeptide(hydrophilic moiety) and non-polar alkyl chain(hydrophobic moiety)[2]. In this work, three different sets of cationic surfactants from glycine have been synthesized. These compounds were confirmed using 1H NMR spectroscopy and studied by several methods like conductivity and polarization microscope. The interaction of dodecyl dimethyl(3-sulfopropyl)-ammonium with anionic surfactants like SDS(sodium dodecyl sulfate)were studied by DSC(differential scanning calorimetry)[3]. The results showed that amino-acid surfactants presented lower cmc(critical micelle concentration), lower Krafft temperature and better biological performance compared with traditional surfactants, which is important for biotechnological applications.

The image of Mulan is well known to the public as an important symbol in the dissemination of Chinese excellent traditional *** paper aims to summarise the mother-title from traditional canonical texts,to explore the content and value of sustainable IP development,and to study a large number of derivatives with the image of Mulan as the mother-title,based on the wide circulation of the prototype of the mother-title“The Poem of Mulan”(木兰辞)and the positive values conveyed by the *** the processing and imagination of scholars and writers on the mother text in the past generations,the image of Mulan has gradually formed a relatively stable cultural communication theme in the process of dissemination in China’s historical period,and many adaptations with international influence based on the mother title of Mulan have emerged in the foreign dissemination,so through the combing and summarisation of the textual works of various periods both at home and abroad,we will dig out the textual transmission of the mother title of Mulan,which is representative of the mother title of China’s excellent traditional culture,and the development of the Chinese spiritual *** Development of the Chinese Spiritual *** paper adopts research methods such as documentary evidence method and discourse analysis to show the textual flow of Mulan’s parent theme in a more diversified form.

采用高温自蔓延制备的碳化锆粉体作为原料,研究了碳化锆陶瓷在空气中的氧化机制和热压烧结块体的氧化动力学行为。结果显示:在空气中,碳化锆陶瓷在200℃时开始氧化;在200～450℃时,氧化产物为ZrCxO1–x(x=0～0.42);在500～600℃时,生成中间相Zr2O出现;当氧化温度升高到1000℃,氧化产物主要为ZrO2。对烧结体的氧化动力学行为分析发现,在200～450℃的氧化过程中烧结陶瓷表面形成ZrCxO1–x致密氧化层,氧化层会抑制氧原子的扩散。当表层氧化产物为ZrC0.42O0.58时,氧化反应基本停止,达到一个稳定状态。继续升高温度,由于产物(Zr2O和ZrO2)的晶型结构发生较大的变化,烧结块体会开裂破坏。随着固溶氧的增加,ZrCxO1–x(x=0～0.42)的电阻从37μcm增加到690μcm。

电缆与附件复合介质界面的电荷特性,不仅与复合介质界面极化机理有关,也受到高场强下电极注入电荷的影响。另外,电缆与附件界面涂覆料也会影响界面电荷的积聚和消散特性。文中基于附件安装工艺中常用的普通硅脂和氟化硅脂两种硅脂涂覆料,测量了交联聚乙烯/三元乙丙橡胶（XLPE/EPDM）复合介质在不同硅脂涂覆下,外施不同极性电压时界面电荷积聚和消散特性,通过体预压和界面击穿试验探讨了界面残余电荷对界面击穿电压的影响规律。研究结果表明：涂覆氟化硅脂试样的界面电荷量多于涂覆普通硅脂试样。且涂覆氟化硅脂时,界面残余正电荷的衰减速率远高于界面残余负电荷的衰减速率。另外,当界面残余电荷极性与界面针电极极性一致时,有利于提高界面击穿电压,反之亦然。界面涂覆氟化硅脂试样的界面击穿电压均低于涂覆普通硅脂试样。

将《高僧传》中的"材理"释为"裁断""整理"或"制弓材料的质地纹理"均有不妥。通过辨析已有解释存在的主要问题、梳理"材"和"理"的主要意义、检视"材理"的文献用例及出现语境,发现"材理"一词自西晋至清代都有使用,主要表示树木或木材的质地、树木或木材的纹理、人的"才能"等义。比照历史文献中"材理"的出现语境,研读《高僧传》的上下文意,其中的"材理"当指封函材质的纹理,"材理自成字"指封函材质的纹理自然呈现出文字,借以彰显安世高的神通广大。
