《笑傲江湖》与《渴望》《过把瘾就死》的意象与符号

《笑傲江湖》中的男女已不是单纯的性别符号，而是隐含着深邃的哲学意蕴的象征意象；《渴望》《过把瘾就死》所制造的女人，几乎是一组畸形病态的怪异符号。     

魏晋南北朝的城市文学--以宋齐梁陈为例

魏晋南北朝的城市较前代有了迅猛的发展,而城市发展带来了文学版图的城市化格局.以宋齐梁陈为例,无论是文学创作还是文学理论都有不俗的表现,并与城市密切相关.魏晋南北朝文学具有鲜明的城市化特征,城市是文学创作的渊薮,城市除了深刻影响文学的生产,也深刻影响着文学的消费或传播.这一切决定了魏晋南北朝文学创作的趋同性和绮丽繁华的城市品格.     

班公湖－怒江缝合带侵入岩地球化学和年代学特征及形成构造背景

对西藏纳屋错地区班公湖－怒江缝合带西段的侵入岩进行岩石地球化学和锆石 U-Pb年龄测定,并与缝合带以外南面岩浆弧侵入岩进行对比。岩石地球化学分析表明,缝合带内侵入岩样品均属于钙碱性和高钾钙碱性系列,隶属于岛弧型岩浆岩类。稀土元素球粒陨石标准化分布模式均表现出 LREE 富集、HREE 相对亏损的右倾模式,痕量元素原始地幔标准化蛛网图显示样品总体上富集大离子不相容元素（HFSE）Rb、K、Ba,亏损高场强元素（LILE）Nb、Ta、Ti、P,体现了钙碱性系列岩体的特征和演化趋势;年代学分析表明,带内侵入岩的成岩时代集中在早白垩世（104．5～141．7 Ma B．P．）;进一步的构造环境对比分析表明,所有侵入岩样品均属于岛弧型-大陆碰撞型花岗岩类,但缝合带内岩浆岩属性为同碰撞花岗岩,缝合带具由钙碱性向高钾钙碱性演化的特征和趋势,形成于受逆掩构造或地壳剪切作用的造山时期,处于威尔逊旋回的“陆陆碰撞造山-山带剥蚀”阶段,认为班-怒缝合带西段存在双向俯冲的碰撞造山构造背景。

季风的年变程

对流层低层的风可以看成是二部分的组合,一部分是季风,而另一部分是非季风的行星风。在对流层低层行星风的季节性变化很小,所以可以用多年平均的年平均风来代表。这样,就可以将季风从实际风中分离出来。作者用这种分离出来的季风讨论了亚洲、非洲、澳洲和印度尼西亚四个著名的季风区季风的年变程。     

魏晋南北朝时期的黄河航运

魏晋南北朝时期,黄河是北方地区水上交通的大动脉。曹魏及北魏等北方政权对黄河航运积极开发,三门峡及其以东峡谷航道不断得到整治。黄河上游部分河段及整个中下游河段都有航运利用。“黄河也曾千帆过”是这一时期并不少见的情形。受水文及政治因素影响,各河段的航运状况不尽相同。     

Progress in the stratigraphy and geochronology of the Shuidonggou site, Ningxia, North China

In the past years we carried out further stratigraphy division in field and it is found that rich stone artifacts can be found in fluvial-shallow lake-alluvial sediments on the terrace Ⅱ of Biangou River, inShuidonggou site, Ningxia and they are SDG1, 2 and 7. More luminescence and AMS ^14C dating in laboratory show that Paleolithic culture develops during the Upper Paleolithic period with ages of 35--20 ka. The Paleolithic culture of SDG 1 is a little earlier than that of SDG 2 similar to SDG 7. The sandy sediments on terrace Ⅱ of Biangou River deposits in the past 72--18 ka, corresponding to Last Glacial. SDG2 has a stable sedimentary environment, resulting in the continuous stratigraphy, thickest deposits and rich environment and culture information, which can be regarded as the important and classic paleoanthropological section of Late Pleistocene in this region.

Coesite in the eclogite and schist of the Atantayi Valley,southwestern Tianshan,China

Coesite is an indicator mineral of ultra-high-pressure metamorphism. Since coesite was reported in the Habutengsu Valley, we have also found it in eclogite and schist from the Atantayi Valley in the southwestern Tianshan, China. Petrographic and micro-Raman analyses were carried out for the Atantayi metamorphic rocks and coesite was recognized in the predominant rock types, i.e. schist and eclogite, from three sections. The coesite-bearing schist consists mainly of garnet, Na-Ca amphibole, quartz, white mica and albite; the coesite-bearing eclogite is mainly composed of omphacite, garnet, glaucophane and zoisite. The coesite occurs as various mineral inclusions within porphyroblastic garnet. Findings of coesite in eclogite and associated schist indicate not only the regional in situ formation of the Atantayi ultra-high-pressure eclogite, but also the large areal extent of ultra-high-pressure metamorphism in southwestern Tianshan, extending up to 10 km north-south and 60-80 km east-west.

Trace metals in soil, dust, and tree leaves of the urban environment, Guangzhou, China

Metals have been constantly introduced to urban environments via various point and non-point sources of pollution,and have contaminated different urban compartments(sample types).However,most research projects have focused on a single environmental compartment to characterize urban metal contamination.In the present study,an integrated sampling program that includes surface soils,different size fractions of soil and road dust(<50 μm,50-100 μm,100-250 μm,and 250-1000 μm),tree leaves,and grasses,was conducted in a typical urban area of Guangzhou,China.The aim of the study was to investigate the interrelationships among the metal pollutants in these samples.The concentrations of trace metals varied greatly among different sample types,and their distribution was generally in the following order:road dust > soil dust ≥ surface soils ≈ top soils > grasses ≥ tree leaves.As for the relationships among the trace metals,different combinations were seen among the sample types,indicating different loadings of trace metals in the sampling medium.Significant correlations of metal concentrations were found between tree leaves and the smallest(<50 μm) fraction of road dust,and between soil dust(50-100 μm) and surface soils,suggesting that trace metals in these samples may influence each other.     

螺蛳对重金属元素的富集作用

用原子吸收分光光度法研究了不同地点的水体和螺蛳体内的铜、锌、铬、镉、铅５种重金属的含量,结果显示水体中锌的含量最高达到１７μｇ／Ｌ,其次是铜为３μｇ／Ｌ,铬和铅在１μｇ／Ｌ左右,镉的浓度最低,只有０．２μｇ／Ｌ,除了一个公园池塘水体中重金属浓度随季节夏、秋、冬的变化升高外,其他水体中重金属的浓度有不同程度的降低,与水体中重金属浓度相比较、螺蛳对这５种重金属都有富集作用,其中对锌和铜的富集可达到数十     

园林历史研究中的量化及分析算法研究 ——以南京明、清杏花村地块为例

【目的】基于园林历史研究中大量私家园林历史信息数据化及数据分析问题,探索比传统研究范式在样本覆盖率和信息复杂降低程度两个方面更佳的研究路径。【方法】以明、清时期南京杏花村地块的45处私家园林为研究对象,通过梳理、验证历史信息,将45处园林、57项独立特征转化为合计2 565项的历史信息判定矩阵。对信息矩阵进行K-means聚类和主成分分析,并将聚类和降维之后的结果从样本覆盖率和信息复杂降低程度两个方面,与传统研究范式,如通过四要素、园主人等分类后提取高频特征研究的方法进行比对,同时比较了传统、聚类、主成分分析所得历史信息规律的差异。【结果】分析比较指出,传统分类后高频的研究方法样本覆盖率一般为45%,信息复杂度约为原样本的70%;指定分类数为5的K-means聚类算法样本覆盖率约为42%,信息复杂度约为原样本的63%;而采用主成分分析法可以跨过分类步骤,得到合计70%以上、信息复杂度为原样本44%的规律。在分类后获得的历史性规律中,采用传统方法只能得到离散信息,以K-means聚类后可以得到跨类型的规律,而用主成分分析法不但能得到跨类型规律,还具有提示性强、特征明显的优点。【结论】南京杏花村地块历史园林发展脉络中,园林的要素和风格更多受地块内已有园林形态影响,而非园主人身份或造园风尚引导,这突破了已有范式的常见结论。在园林历史研究中,面对大量私园时,主成分分析法具有样本覆盖率高、信息复杂度低的优点,是一种可参考的研究路径。     

谷物、蔬菜对铅、镉、锌、铜吸收与富集的研究

本文报导了1978～1983年上海市郊区梅龙、龙华、宝山吴淞、青浦淀山湖周围等地区的谷物、蔬菜受环境污染物质及其含量的影响,以及对铅、镉、锌、铜的吸收与富集。结果表明:不同谷物蔬菜对各种重金属元素的吸收和富集能力是有明显差别的。同一谷物蔬菜的不同部位,对各种重金属元素的吸收与富集能力也是各不相同的。谷物与蔬菜中重金属含量的高低与距离污染源的远近呈正相关。其锌/镉、锌/铜比值具有明显差异。文章最后讨论了谷物蔬菜的重金属污染对人体的影响,蔬菜重金属污染的评价标准,以及对谷物蔬菜食用部位监测农业生态环境的重要性等。
