竟陵别调——马之骏与《妙远堂诗钞》

明朝中后期的诗人马之骏,在当今的中国古代文学史研究中无人提及,对其文学创作的研究也几乎是空白.其实他在当时颇有诗名,并同竟陵派的钟惺互为诗酒之友.其留有诗文集<妙远堂集>四十卷.后人曾于清代重刻其诗歌选集<妙远堂诗钞>五卷,收马氏诗800余首.     

控制给水管网的漏损

由于管网运行压力、管材、施工质量、地质和气候条件等因素产生的给水管网漏损,给供水行业造成严重的损失。企业除通过管道的更新改造、调整管网压力、经常采用区域检漏等方法确定漏点外,还可根据具体情况建立给水管网监控和数据采集、管网地理信息等系统,对管网进行实时监控和管理。

离子色谱法测定饮料和水果中的碱金属和铵离子

用吡啶-2,6-二羧酸(PDCA)为流动相的非抑制型离子色谱法同时测定碱金属和铵离子。流动相浓度为1.5mmol·L-1时,Li+、Na+、NH4+和K+峰面积的相对标准偏差(n=5)分别为0.55%、0.68%、0.69%、0.85%,检出限(μg·L-1)分别为11、39、53和130,线性范围(mg·L-1)分别为0.011￣30、0.039￣30、0.053￣30和0.130￣40。方法应用于运动型饮料、绿茶饮料、水蜜桃汁饮料、苹果和梨样品的分析,结果准确、可靠。

Exposure Reconstruction for the TCDD-Exposed NIOSH Cohort Using a Concentration- and Age-Dependent Model of Elimination

Recent studies demonstrating a concentration dependence of elimination of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) suggest that previous estimates of exposure for occupationally exposed cohorts may have underestimated actual exposure, resulting in a potential overestimate of the carcinogenic potency of TCDD in humans based on the mortality data for these cohorts. Using a database on U.S. chemical manufacturing workers potentially exposed to TCDD compiled by the National Institute for Occupational Safety and Health (NIOSH), we evaluated the impact of using a concentration- and age-dependent elimination model (CADM) (Aylward et al., 2005) on estimates of serum lipid area under the curve (AUC) for the NIOSH cohort. These data were used previously by Steenland et al. (2001) in combination with a first-order elimination model with an 8.7-year half-life to estimate cumulative serum lipid concentration (equivalent to AUC) for these workers for use in cancer dose-response assessment. Serum lipid TCDD measurements taken in 1988 for a subset of the cohort were combined with the NIOSH job exposure matrix and work histories to estimate dose rates per unit of exposure score. We evaluated the effect of choices in regression model (regression on untransformed vs. ln-transformed data and inclusion of a nonzero regression intercept) as well as the impact of choices of elimination models and parameters on estimated AUCs for the cohort. Central estimates for dose rate parameters derived from the serum-sampled subcohort were applied with the elimination models to time-specific exposure scores for the entire cohort to generate AUC estimates for all cohort members. Use of the CADM resulted in improved model fits to the serum sampling data compared to the first-order models. Dose rates varied by a factor of 50 among different combinations of elimination model, parameter sets, and regression models. Use of a CADM results in increases of up to five-fold in AUC estimates for the more highly exposed members of the cohort compared to estimates obtained using the first-order model with 8.7-year half-life. This degree of variation in the AUC estimates for this cohort would affect substantially the cancer potency estimates derived from the mortality data from this cohort. Such variability and uncertainty in the reconstructed serum lipid AUC estimates for this cohort, depending on elimination model, parameter set, and regression model, have not been described previously and are critical components in evaluating the dose-response data from the occupationally exposed populations.     

理性之美,女性之美--诠释西蒙娜·德·波伏瓦的女性生存论思想

波伏瓦以哲学理性反思和批判女性的生存状态,探求女性解放的道路。她认为,不存在“永恒的女性气质”,女性的“内在性”是历史的产物,也能够历史性地加以克服。实现经济独立、摆脱爱情依附是女性克服内在性的重要条件,实现自由是女性解放的目标。解放了的女性应当在平等中求差别,与男性建立情同手足的兄弟关系。     

女性个体生命的探究与表达--关于丁玲20世纪40年代的个性化写作

20世纪40年代初期,丁玲的写作显然呈现出有别于30年代的个性气质,这是她对自己在20年代的写作个性的一次回归.在丁玲个人的写作历史上,这次回归再次印证着她真正的文学禀赋对女性个体生存困境的揭示,以及敏感而细腻的传达能力.但由于当时的文艺气氛和丁玲的特殊遭遇,这种个性化写作很快中断.     

北魏龙门石窟造像和书迹艺术研究

对北魏龙门石窟艺术的研究,向来被人为割裂成了造像和书法两个联系不大的方面,各自为阵,分别为美术考古和书法艺术两个领域所热情关注,而将二者有机结合起来作全面审视和探讨的情况却基本没有。本文分别从其历史地位、艺术特色及对后世的影响入手,意在还北魏龙门石窟艺术一个真实面目。
