Methods: A tablet of home-made povidone iodine was placed in 25 ℃ and 30 ℃ attemperator relative humidity was 75%） after weight and packed. And the quality and the contents of effective iodine in a pellet of home-made povidone iodine were measured on first day as well as 30, 60, 90, 120, 150 and 180 days after placed.

Grain boundary segregations of microelements Sn arc As in U74 heavy-rail steel after austeniized at 1200℃ then cooled at different colling rates were determined by means of Auger electron spectrum and X-ray surface analysis.

用Auger谱仪和X射线面扫描探测了U_(74)重轨钢在加热到1200℃奥氏体化以后再以不同冷速进行冷却的条件下微量元素Sn，As的偏聚情况。

FT-IR spectra shows that the polyaniline is present primarily in the emeraldine salt form, and the polymeric chains interact with inorganic framework, most likely via V=O…HN hydrogen bonding. XRD,TG and DSC indicate that the lamellar structure of the V_2O_5 is preserved, PAn chains eliminate water form the interlamellar region and are partially inserted between the layers, and exist with extended-chain conformation owing to the confined environment.Electrochemical investigation in the range of 1.8~3.8V vs.

红外光谱表明复合物中PAn主要以导电聚苯胺盐的形式存在，PAn链与V_2O_5晶格之间可能形成了V=O…HN氢键。X射线衍射、热重和差示扫描量热证实了PAn/V_2O_5复合物保持了较规整的层间排列结构，PAn取代了V_2O_5干凝胶中的层间水而部分嵌入其片层间，由于受空间的限制，PAn分子链以比较伸展的链构象存在。

In the present work poly is prepared by chemical vapor deposition polymerization from [2.2] paracyclophane. Thermal gravimetrical analysis is used to study the thermal degradation. It is found that the onset of thermal degradation of poly in air is much lower than that in N2 due to the existence of O2 in the air.

用化学气相沉积聚合法制备了聚对亚苯基二亚甲基膜，由傅立叶变换红外光谱图证实了其化学结构采用热重分析研究了PPX的热降解性能，结果表明，在空气氛围中由于氧气的参与，其热稳定性比在N2中差，热氧化降解明显。

They interweave together each other, tend to changing constantly, power and shape , they fine long hair sometimes flow , sometimes congeal and stop , erupt sometimes irregular, disappear sometimes," some such things change like lights of forest like that in feeling of us, it hand in again and the overlapping:" Gather into certain form again when they have not offsetted and concealed each other, but this kind of form in often resolving, or break out in the fierce conflict for the passion, or become changed beyond recognition in this kind of conflict , all these things blend subjective reality make up man we call that inalienably for an organic whole " The inherent life " Thing promptly emotions human so-called.

它们相互交织在一起，不断地改变着趋向，强弱和形态，它们毫无规律地时而流动，时而凝止，时而爆发，时而消失，&这样一些东西在我们的感受中就象森林中的灯火那样地变化不定，相互交又和重迭&当它们没有相互抵消和掩盖时便又聚成一定的形状，但这种形状又在时时的分解着，或是在激烈的冲突中爆发为激情，或是在这种冲突中变得面目全非，所有这些交融为一体不可分割地主观现实就组成丁我们称之为&内在生命&的东西即所谓人类情感。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
