特种纤维的鉴别

中国纤检 1982年第5期 40-45页

作者： Kenneth D.Langley thomas A.kennedy 万方汤加乐

由于特种纤维的价格昂贵,且常与羊毛混用,因此需要一种能区分这两类纤维的方法。某些有光羊毛,粗细均匀且鳞片较长,象马海毛,但是在鳞片厚度和光泽等方面却与马海毛有明显的差别。山羊绒(开士米)和驼毛很细,直径略有些不匀整,但山羊绒... 详细信息

由于特种纤维的价格昂贵,且常与羊毛混用,因此需要一种能区分这两类纤维的方法。某些有光羊毛,粗细均匀且鳞片较长,象马海毛,但是在鳞片厚度和光泽等方面却与马海毛有明显的差别。山羊绒(开士米)和驼毛很细,直径略有些不匀整,但山羊绒的鳞片宽,而驼毛的鳞片几乎呈鼓形。羊驼和安哥拉兔毛的纤维鳞片截然不同,毛髓特征也各不相同。

背景：造影剂肾病仍是放射影像学检查的一种常见并发症。在动物急性缺血性肾衰竭模型中，预先使用碳酸氢钠比氯化钠的肾脏保护作用更佳。缺血和造影剂引发的急性肾衰竭均被认为是自由基损伤所致。但是，在人或动物至今尚无评价碳酸氢钠预防造影剂肾病有效性的研究。目的：在使用放射性造影剂前后用碳酸氢钠或氯化钠进行预防性水化，比较二者的有效性。设计、地点和病人：一项于2002年9月16日至2003年6月17日进行的前瞻性、单中心、随机试验。119例血清肌酐稳定在≥1．1mg／dL（t≥97．2μmol／L）水平的病人，在应用碘帕醇（370mg碘／mL）造影前后，随机接受了氯化钠静脉滴注（n=59）或碳酸氢钠静脉滴注（n=60），剂量均为154mEq／L。在造影前及造影后第1、2天进行了血清肌酐检测。干预：病人接受154mEq／L的氯化钠或碳酸氢钠，造影前以每小时3mL／kg的速度静脉滴注1小时，造影后以每小时1mL／kg的速度滴注上述药物6小时。主要观察指标：造影剂肾病，其定义为在造影后2天内血清肌酐升高tμ25％。结果：两组病人在年龄、性别、糖尿病发生、种族以及造影剂用量方面无显著差异。碳酸氢钠治疗组病人基线血清肌酐水平稍高于氯化钠治疗组，但亦无显著差异（氯化钠组均值[sD]为1．71[0．42]mg／dL[151．2{37．1}μmol／L]，碳酸氢钠组为1．89[0．69]mg／dL[167．1{61．0}μmol／L]；P=0．09）。氯化钠组8例（13．6％），发生造影剂肾病一级终点，而碳酸氢钠组仅1例（1．7％）（均值差别，11．9％；95％可信区间[CI]，2．6％～21．2％；P=0．02）。随后，又对191例符合研究纳入标准的病人给予了碳酸氢钠治疗并进行随访登记，结果有3例出现了造影剂肾病（1．6％；95％CI，0％～3．4％）。结论：对于造影剂引发的肾衰竭，在造影前采用碳酸氢钠进行水化治疗比采用氯化钠水化治疗更为有效。

Forest dynamics is highly relevant to a broad range of earth science studies,many of which have geographic coverage ranging from regional to global *** the temporally dense Landsat acquisitions available in many regions provide a unique opportunity for understanding forest disturbance history dating back to 1972,large quantities of Landsat images will need to be analysed for studies at regional to global *** will not only require effective change detection algorithms,but also highly automated,high level preprocessing capabilities to produce images with subpixel geolocation accuracies and best achievable radiometric consistency,a status called imagery-ready-to-use(IRU).This paper describes a streamlined approach for producing IRU quality Landsat time series stacks(LTSS).This approach consists of an image selection protocol,high level preprocessing algorithms and IRU quality verification *** high level preprocessing algorithms include updated radiometric calibration and atmospheric correction for calculating surface reflectance and precision registration and orthorectification routines for improving geolocation *** automated routines have been implemented in the Landsat Ecosystem Disturbance Adaptive System(LEDAPS)designed for processing large quantities of Landsat *** characteristics of the LTSS developed using this approach are discussed.

In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave *** paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.
