聚苯乙烯(PS)是惯性约束聚变(ICF)实验中重要的靶丸材料,磁性聚苯乙烯材料有利于实现靶丸在辐射场中的无接触支撑。本工作以FeCl3、FeCl2和NaOH为原料,在分散剂的作用下,制得均匀分散的棕黑色Fe3O4磁流体,然后与苯乙烯聚合获得Fe3O4-聚苯乙烯磁性材料。激光粒度分布测试结果显示,所得磁流体的粒度小且分布均匀;XRD分析表明,磁流体中无其它杂相存在。此外,还对Fe3O4-聚苯乙烯磁性材料进行了DTA及FTIR分析。分析测试结果表明,采用本工作所设计的方法可合成出Fe3O4-聚苯乙烯磁性复合材料。

研究了金刚石格点上自避随机行走（ＳＡＷ）尾形链，采用精确计数和ＭｏｎｔｅＣａｒｌｏ模拟方法求得该ＳＡＷ尾形链的构象数Ｃ（Ｄ）１（Ｎ）和均方末端距［ｈ（Ｄ）１（Ｎ）］２及其分量随链长Ｎ的变化关系．发现它们与自由ＳＡＷ链一样都服从标度律，从这些量的计算机实验数据拟合求出了金刚石格点上ＳＡＷ尾形链的临界指数和格点指数．计算结果还表明短链ＳＡＷ在壁的法向与ＮＲＷ尾形链一样有所伸展，均方末端距的法向分量几乎是平行分量的２倍；但随Ｎ→∞，链自回避效应对壁的作用有所屏蔽．这些都与简立方格子模型上得到的结果一致．

梁启超与拜伦《哀希腊》的本土化

外语研究 2006年第3期23卷 48-51页

作者：廖七一四川外语学院翻译研究所重庆400031

梁启超是翻译拜伦《哀希腊》的第一人。在其翻译中,他有意识地突出目的文化本位,强调诗歌翻译的社会政治功能,并以此协调政治目标与翻译规范与策略的冲突,塑造出中国化的拜伦与《哀希腊》的想像,使其成为民族救亡和复兴的符号象征。

语言规范是一个社会共同期待和接受的语言表现形式。晚清的文学翻译时逢语言规范变动不居、不同规范彼此冲突的过渡期。诗歌、短章用文言翻译,长篇用白话翻译是其基本形态。然而,"林译说部"风靡一时,引发了翻译和创作语言规范的"变格"。随着五四新文学运动的兴起,白话不可逆转地取代文言而成为翻译与创作的主流规范。

基于前瞻性货币政策理论,运用VAR模型和方差分解技术对1998年1月-2009年9月间我国货币政策的内部时滞进行实证研究。在1998年1月-2009年9月间我国货币政策存在一定程度的内部时滞。消费者信心指数和企业家信心指数与前瞻性货币政策存在长期稳定的因果关系。因此,货币当局实行前瞻性货币政策时短期政策应盯住企业家信心指数,中长期政策应盯住消费者信心指数。

Chinese Medical Journal 2017年第22期130卷 2703-2708页

作者： Hui Zhou Liang-Cai Wu Mu-Kai Chen qi-Man liao Ren-Xiang Mao Jian-De Han Department of Dermatology The First Affiliated Hospital Sun Yat-sen University Guangzhou Guangdong 510080 China Department of Dermatology The Sixth Affiliated Hospital Sun Yat-sen University Guangzhou Guangdong 510650 China

Background： Halo nevus （HN） has been shown to be associated with vitiligo, but no standard signs are currently available to identify HN patients at risk of vitiligo, and the relevant data obtained in previous studies are somewhat conflicting. This study aimed to identify factors affecting the presence of vitiligo in HN patients. Methods： We performed a retrospective study on consecutive patients with HN at the First Affiliated Hospital of Sun Yat-sen University between January 2011 and December 2016. Detailed demographic and clinical data were collected to identify the factors associated with the presence ofvitiligo in this cohort of patients using uni- and multi-variate logistic regression analyses. Results： A total of 212 HN patients were included, 101 of whom had vitiligo-associated HN （HNV）. Univariate analysis indicated that a personal history of thyroid diseases was positively associated with HNV （odds ratio [OR] 10.761, P = 0,025）, while the onset age of HN was negatively associated with HNV （OR =0.537, P= 0.026）. Multivariate analysis demonstrated that the Koebner phenomenon （KP： OR = 10.632, P 〈 0.0001）, multiple HN （OR = 3.918, P 〈 0.0001）, and a familial history of vitiligo （OR = 3.222, P= 0.014） were independent factors associated with HNV. Conclusions： HN without vitiligo has clinical features distinct from HN associated with vitiligo. HN patients with KR multiple lesions, or familial history ofvitiligo are more likely to develop vitiligo and theretbre should be monitored for clinical signs of such accompanied conditions.

The purpose of this research was to better understand the water quality status of the Xiangjiang River, China, and to evaluate the risks posed by the river water. Precisely, ten water quality parameters including p H, dissolved oxygen(DO), Escherichia coli(E. coli), potassium permanganate index(CODMn), dichromate oxidizability(CODCr), five-day biochemical oxygen demand(BOD5), ammonia nitrogen(NH4+-N), total phosphorus(TP) and fluoride(F-) as well as metal(loid)s(Pb, Hg, Cd, As, Zn, Cu and Se) were monitored monthly in 2016 at 12 sampling sites throughout the Hengyang section of the Xiangjiang River. Concentrations of all parameters were presented according to rainy and dry seasons. They were compared with Chinese surface water standards and WHO drinking water limits to assess the sustainability of the river water status. Principal component analysis(PCA) revealed different pollution sources in different seasons. Dual hierarchical cluster analysis(DHCA) was applied to further classify the water quality variables and sampling sites. Besides, a risk assessment was introduced to evaluate the carcinogenic and non-carcinogenic concerns of heavy metal(loid)s to human health. This research will help to optimize water monitoring locations and establish pollution reduction strategies on the preservation of public safety.
