1电-热耦合对航空复合材料拉伸及疲劳性能的影响显示文摘为研究碳纤维增强树脂基复合材料(CFRP)层合板的导电性能和电-热耦合效应及其对拉伸和疲劳性能的影响,主要针对2种不同铺层的试件(单向层合板(UD)[0]8和准各向异性层合板(QI)[45/90/-45/0]s)进行导电及电-热耦合实验和通电状态下的拉伸及疲劳实验.在电-热耦合实验中分别对试件通以1~8 A的直流电和交流电,测量其温度场的分布及最高温度,以确定温度对电阻的影响.依据实验现象建立了简化后的电-热耦合分析模型,并与实验结果进行对比,发现两者吻合很好.简化后的电-热耦合模型能够很好地预测试件在达到稳态平衡时的最高温度值.在通电情况下对不同初始状态时的QI试件进行拉伸和疲劳实验,通过实验发现,在疲劳加载过程中无论是通以直流电、交流电或者是改变电流强度和电流频率,对试件的疲劳寿命影响不大,没有发现明显差异,但在实验过程中试件表面的温度会随着电流强度的增加而升高.同时,在监测试件沿着纤维方向的电阻变化时发现,在一定的疲劳载荷下,随着循环次数的增加,试件的电阻会不断增加,这表明试件内部出现了损伤,累积后直至试件断裂.依据实验现象分别建立了电阻模型-1和电阻模型-2,分析计算后发现模型-1能够较好地模拟试件变形的线性阶段(εxx≤0.4%),而模型-2能较好地模拟非线性阶段直至试件断裂(εxx>0.4%).蔺越国 Macro GIGLIOTTI Marie Christine LAFARIE-FRENOT Jinbo BAI 2014航空学报2014,35,12:4
2P27^(kip1)在胰腺癌中的表达及临床意义显示文摘目的 研究P2 7kip1在胰腺癌发生发展中的作用及预后意义。方法 用免疫组织化学方法研究P2 7kip1在 39例胰腺癌手术切除标本及 5例正常胰腺标本中的表达 ,其结果与临床病理资料及CyclinD1的表达进行相关性分析。结果 39例胰腺癌中 ,2 6例 (6 6 7% )P2 7kip1呈低水平表达 (阳性细胞数 <5 0 % ) ,仅 13例 (33 3% )表达水平与正常胰腺组织相似 (阳性细胞数 >5 0 % )。相关分析显示 :P2 7kip1表达缺失或下调与肿瘤的不良分化相关 (P =0 0 3) ,但与性别、年龄及TNM分期无关。Kaplan Meier生存曲线表明 ,肿瘤呈高表达的病人术后总体生存期较低表达者明显延长 (P <0 0 1)。此外 ,还发现P2 7kip1与CyclinD1的表达呈负相关趋势 ,但未达到显著性水平 (P =0 0 98)。 结论 P2 7kip1在胰腺癌发生、发展中有重要的作用 ,可作为胰腺癌切除后一种新的预后指标。乔岐禄 杨尹默 Macro Ramadani 万远廉 黄莚庭 2003中华肝胆外科杂志2003,9,5:2
3Probability Distribution and Projected Trends of Daily Precipitation in China显示文摘Based on observed daily precipitation data of 540 stations and 3,839 gridded data from the high-resolution regional climate model COSMO-Climate Limited-area Modeling(CCLM)for 1961–2000,the simulation ability of CCLM on daily precipitation in China is examined,and the variation of daily precipitation distribution pattern is revealed.By applying the probability distribution and extreme value theory to the projected daily precipitation(2011–2050)under SRES A1B scenario with CCLM,trends of daily precipitation series and daily precipitation extremes are analyzed.Results show that except for the western Qinghai-Tibetan Plateau and South China,distribution patterns of the kurtosis and skewness calculated from the simulated and observed series are consistent with each other;their spatial correlation coefcients are above 0.75.The CCLM can well capture the distribution characteristics of daily precipitation over China.It is projected that in some parts of the Jianghuai region,central-eastern Northeast China and Inner Mongolia,the kurtosis and skewness will increase significantly,and precipitation extremes will increase during 2011–2050.The projected increase of maximum daily rainfall and longest non-precipitation period during flood season in the aforementioned regions,also show increasing trends of droughts and floods in the next 40 years.CAO Li-Ge ZHONG Jun SU Bu-Da ZHAI Jian-Qing Macro GEMMER 2013Advances in Climate Change Research2013,4,3:2
