The time during which the map of each province in Shilinguangji was charted and the value of these maps

《事林广记》所附分省图是今见较早的中国古代系统的分区地图。本文从各幅分省图所载政区地名入手，结合《元史》、《新元史》、《大元一统志》、《大元混一方舆胜览》等文献中的相关记载，仔细考辨其建置沿革，分别考证各幅分省图所反映的地理面貌，就其绘制年代、所根据的地理信息与底图、史料价值等问题，形成了一些初步认识： （1）各幅分省图的绘制年代及其所据底图并不一致，然其最终汇集制图并刻版印刷，大抵不出延祐年间（1314—1320）；因此，总的说来，它们反映了元朝前期各行省的政区地理面貌。 （2）在各分省图中，“腹里图”、“汴梁行省所辖图”、“陕西行省所辖图”较多反映了金元之际的政区变动情形，“云南行省所...The provincial maps attached to Shi Lin Guang Ji（《事林广记》）are the earlier systematically district maps in the traditional China that can be seen today. This paper firstly discusses the names of administrative districts in the provincial maps.

The Research of Xunzi’s Heart and Human Nature Theory

中国哲学传统的一个基本理论意向是追求人的生命价值，为此而“穷究天人之际”，所以在一定意义上来说对于人之本质的认识或曰人性论构成了中国哲学传统的核心内容之一。本文对荀子的心性学说进行了详细的论述，首先以对性的探讨为出发点，涉及到与性有紧密联系的天的概念，从而进一步集中说明什么是荀子所定义的性，指出荀子关于性的内容主要指向的是官能和官能的欲望，官能的能力和性中所包含的情和欲。心在荀子哲学中受到了很大的重视，它被赋予具有思维认识能力和能动的能力，这就不仅使心具有认识论意义，也由此引出修身和修心的理论，荀子的心在对荀子人之性恶也进行了翻转，所以这使得荀子的性恶有了走向善的可能。荀子的经验主义性格又不可...In the tradition of Chinese philosophy, there is a basic theoretical intention to investigate thoroughly the relationship between Heaven and mankind for the value of human life. In a sense, the understanding of human’s essence, or the theory of human nature, constitutes one of the core contents of Chinese philosophical tradition. This article will have a detailed discussion about Xunzi’s theory of...学位：哲学硕士院系专业：人文学院_外国哲学学号：1042011115220

Piecewise Frequency Design Method of Dynamic Output Feedback System

该文考虑一个线性系统满足多频段不同设计指标的控制问题,改进已有的gkyP引理,提出分频段控制思想,将控制综合指标fdI(频率不等式)表示形式转化为lMI线性矩阵不等式形式,设计有限频段的动态输出反馈控制器。通过对柴油发动机转速控制器的仿真验证了这一思路的可行性。In this paper, the control system is considered in three different frequency domains.According to the method used in papers [4], the new method, dynamic output feedback synthesis based on piecewise frequency design method is proposed.In particular, the controller is designed under the sensitivity specifications for three frequency ranges (low, middle, high frequency) without weighting functions, such that the resulting closed-loop systems are asymptotically stable.Finally, design examples for a diesel generator set speed control system are given to prove the feasibility of the proposed method.厦门大学985二期信息创新平台项目资助;福建省新世纪优秀人才支持计划资助;福建省自然科学基金(A0510002

Spreading area and shape regulate apoptosis and differentiation of osteoblasts

The in vivo observations have indicated that at the remodeling sites of bone, the spreading area or shape of preosteoblasts is confined by the mineralized matrix. But it remains unknown whether this spreading confinement regulates the differentiation or apoptosis of osteoblasts. In the present study, osteoblast-like cells (MC3T3-E1) were seeded on micropatterned islands with different area and shape. The expression of three osteogenic differentiation markers was measured by immunofluorescence staining and apoptotic cells were detected using a terminal deoxyribonucleotidyl transferase-mediated dUTP nick end labelling assay kit. The membrane fluorescence staining results showed that the actual spreading area of micropatterned osteoblasts coincided with the designed value. When the area of a micropatterned cell was confined as 314 or 615 mu m(2), which was lower than that of freely spreading osteoblasts, the circular shape promoted the expression of osteogenic differentiation markers and the percentage of apoptotic osteoblasts compared with the branched shape. This shape-regulated differentiation and apoptosis of osteoblasts with confined spreading area were abolished when actin polymerization was inhibited by cytochalasin D. The present study gives an insight into the roles of spreading morphology on osteoblastic differentiation and apoptosis

目的比较体外受精-胚胎移植(IVf-ET)与单精子卵胞浆内注射(ICSI)受孕双胎妊娠围生期并发症及结局。方法回顾性分析我院2004年2月~2011年5月437例IVf-ET、ICSI受孕双胎的并发症(如胎膜早破、胎盘早剥、妊娠期高血压疾病、妊娠期肝内胆汁淤积症)及妊娠结局(流产发生率)。结果 IVf-ET受孕双胎组胎膜早破及胎盘早剥发生率高于ICSI受孕双胎组(χ2=5.93,6.01;P0.05);IVf-ET受孕双胎组较ICSI受孕双胎组流产率高,差异有统计学差异(χ2=5.09;P0.05);Ratio of abortion in IVF-ET group was significant higher than that in ICSI group(χ2=5.09;P<0.05).Conclusion:The risk of twin pregnancy by IVF-ET is higher than by ICSI,IVF-ET and ICSI maybe are not the main cause of pregnancy-induced hypertension and intrahepatic cholestasis of pregnancy

潜在血源传播梅毒患者血清抵抗特性分析

目的研究潜在血源传播梅毒患者血清抵抗特性,探讨其传染性和复发的血清学指标。方法在回顾性分析2005年6月-2009年5月厦门大学附属中山医院收治的714例潜在血源传播梅毒患者的血清抵抗特性基础上,采用荧光密螺旋体抗体吸收试验(FTA-ABS)进行梅毒特异性IgM抗体(TP-IgM)检测。结果 714例潜在血源传播梅毒患者中,有242例患者经1年梅毒规范治疗后,其反应素仍保持阳性,血清抵抗率33.89%,其中男性患者血清抵抗率28.08%,显著低于女性患者(40.54%),差异有统计学意义(χ2=12.306,P<0.05);不同检测年度、不同年龄患者血清抵抗率差异无统计学意义;采用FTA-ABS法,242例血清抵抗患者中检出TP-IgM的阳性率为32.23%,显著高于梅毒血清治愈组(10.70%)和献血员组(0)。结论潜在血源传播梅毒患者有着较高的血清抵抗率,是梅毒治疗失败的重要表现,并容易复发和具有传染性,TP-IgM可作为其复发和具有传染性的血清学指标

Proton Conduction of Mesoporous Phosphorus Hybrid SiO_2 at Temperature Range 30℃～200℃

合成了孔壁掺磷中孔SIO2(M-PH-SIO2),其bET比表面积为407M2g-1,bJH平均孔径为6.1nM。用交流阻抗技术测定了除去游离P2O5的掺磷中孔SIO2在30℃~200℃范围内100%相对湿度下的质子电导,样品导电率随温度升高而升高,在150℃和100%相对湿度下,样品的电导可达3.1x10-3S·CM-1,比纯中孔SIO2(M-SIO2)的电导约高一个数量级,原因是M-PH-SIO2的物理吸附水量为31个分子/nM2,而M-SIO2只有24个分子/nM2。The mesoporous SiO2 with P2O5 hybrid in the pore walls(m-PH-SiO2) but not impregnated in the pore tunnels was synthesized.The BET surface of m-PH-SiO2 was 407m2g-1 and the average pore size was 6.1nm.The proton conductivity at temperature range 30℃ ～ 200℃ under 100% RH of the washed m-PH-SiO2 were measured by AC impedance technique.The conductivity of m-PH-SiO2 was enhanced with the increase of temperature,the value of proton conduction at 150℃ under 100% was 3.1 × 10-3 S·cm-1 higher than that of pure mesoporous SiO2(m-SiO2 ) beacaus the m-PH-SiO2 can hold more H2O molecule.The number of H2O molecule on internal surface of m-PH-SiO2 was about 31 per nm2,and the value in m-SiO2 was only 24 per nm2 at the same condition.科技部十一五“863”计划(2008AA05Z107);华南理工大学学生研究计划(SRP

潜在血源传播患者梅毒血清学TRUST/TPPA与IgM抗体联合检测

目的为潜在血源传播患者筛选梅毒血清学传染病指标。方法采用回顾性研究,对2006年6月1日～2009年12月31日本院23720例潜在血源传播患者与门诊患者的TRUST/TPPA联合检测结果进行分析比较;分析不同年度潜在血源传播患者TRUST-/TPPA+的百分率变化;对其中118份TRUST-/TPPA+的潜在血源传播患者血清标本同时采用TPPA法和FTA-ABS法进行Tp-IgM抗体检测。结果潜在血源传播患者和门诊患者的梅毒抗体阳性率分别为8.62%和26.69%,二者差异有显著性;在梅毒抗体阳性标本中,TRUST-/TPPA+占有相当的比例,二者分别为3.12%和7.50%;潜在血源传播患者中TRUST-/TPPA+的百分率呈逐年上升趋势;118份TRUST-/TPPA+的潜在血源传播患者血清,经TPPA法和FTA-ABS法检出TP-IgM抗体阳性分别为13例和10例。结论潜在血源传播患者的梅毒传染性指标的监测应至少包含特异性抗体试验,如TPPA;TP-IgM检测有助于判断其传染性
