纤维对PEI改性环氧树脂单向复合材料形态的影响

人们改善环氧树脂基复合材料的脆性通常只改善环氧树脂基体和增强纤维间的界面，提高环氧树脂韧性的另一种常用方法是添加初始相容性良好的热塑性树脂如聚醚酰亚胺，在某一转化率（取决于体系的组成和反应温度）时体系发生相转变，体系最终的形态由相转变速率和环氧树脂反应速度所控制。本文作者研究了两种增强纤维（玻璃纤维和碳纤维）对不同环氧树脂／聚醚酰亚爱体系形态形成的影响，结果发现体系中纤维的存在不会影响基体相分离过程，但会改变体系的最终形态；形态的变化与纤维的品种关系不大；基体中不同组分的粘度是影响复合材料形态形成的关键因素。

Design and fabrication of 1-D semiconductor nanomaterials for high-performance photovoltaics

To date, the cost-effective utilization of solar energy by photovoltaics for large-scale deployment remains challenging. Further cost minimization and efficiency maximization, through reduction of material consumption, simplification of device fabrication as well as optimization of device structure and geometry, are required. The usage of 1D nanomaterials is attractive due to the outstanding light coupling effect, the ease of fabrication, and integration with one-dimensional(1-D) semiconductor materials. The light absorption efficiency can be enhanced significantly, and the corresponding light-toelectricity conversion efficiency can be as high as their bulk counterparts. Also, the amount of active materials used can be reduced. This review summarizes the recent development of 1-D nanomaterials for photovoltaic applications, including the anti-reflection, the light absorption,the minority diffusion, and the semiconductor junction properties. With solid progress and prospect shown in the past 10 years, 1-D semiconductor nanomaterials are attractive and promising for the realization of high-efficiency and low-cost solar cells.

基于中期基准面旋回变化的沉积微相精细研究——以松辽盆地扶余油田泉四段为例

 从区域沉积背景出发,以岩心和测井资料分析为基础,对松辽盆地扶余油田泉四段的岩石类型、粒度分布、沉积构造、泥岩颜色及地球化学特征等各类沉积相标志进行分析,确定其为三角洲沉积,包含三角洲平原和前缘亚相。其中,平原亚相可识别出分支河道、决口扇、天然堤、废弃河道、湖泊沼泽微相;前缘亚相可细分为水下分支河道、河口坝、远沙坝、水下天然堤和支流间湾等微相。依据沉积微相与地层格架的成因关系,在中期基准面旋回的控制下应用取心关键井建立了沉积微相的定量识别图板,对非取心井进行沉积微相的定量识别与划分,并在此基础上绘制了沉积微相的平面及剖面图,总结了微相类型的平面和纵向展布规律及其与含油性的关系,指出分支河道砂体发育规模、连续性、储集性、含油性最好,其次为河口坝砂体,为研究区下一步的开发方案提供地质依据。     

Fingerprints of global warming on wild animals and plants

Over the past 100 years, the global average temperature has increased by approximately 0.6 degrees C and is projected to continue to rise at a rapid rate. Although species have responded to climatic changes throughout their evolutionary history, a primary concern for wild species and their ecosystems is this rapid rate of change. We gathered information on species and global warming from 143 studies for our meta-analyses. These analyses reveal a consistent temperature-related shift, or 'fingerprint', in species ranging from molluscs to mammals and from grasses to trees. Indeed, more than 80% of the species that show changes are shifting in the direction expected on the basis of known physiological constraints of species. Consequently, the balance of evidence from these studies strongly suggests that a significant impact of global warming is already discernible in animal and plant populations. The synergism of rapid temperature rise and other stresses, in particular habitat destruction, could easily disrupt the connectedness among species and lead to a reformulation of species communities, reflecting differential changes in species, and to numerous extirpations and possibly extinctions.     

标量FDTD法分析渐变折射率光波导模场分布

用标量时域有限差分法（Finite-differece Time-domain Method,FDTD法）分析了渐变折射率平面光波导中基模的模场分布情况，采用平面光波、球面光波、高斯光波等5种不同形态的光波激励同一波导，借助计算机进行数值求解，得到的光场分布图在光场传播达到稳定后完全相同，说明波导的模式与光波形态无关，只与波导结构和光波波长有关，结果表明该方法直观、精确、快速，并与解析法分析的结果一致。
