Currently,highly efficient n-i-p perovskite solar cells rely on an organic interface layer for high efficiency,especially 2,2',7,7'-tetrakis[N,N-bis(4-methoxyphenyl)ami-no]-9,9′-spirobifluorene(spiro-OMeTAD),but the instability of organic materials in the photothermal field compromises device *** this study,we employ the oleic acid(YS)/oleamine(YA)end-sealing method to achieve uniform dispersion of NiO_(X)nanoparticles,effectively mitigating coagulation resulting from high local concentration and secondary motion ***,the conductivity of the hole transport layer and its energy level alignment with perovskite is enhanced by the additional 2,3,5,6-tetrafluoro-7,7',8,8'-tetracyanodimethyl-p-benzoquinone(F4TCNQ),leading to a remarkable improvement of open-circuit voltage and fill factor,thus the high efficiency of 25.17%and 24.36%on 0.1 and 1.01cm2,***,by realizing an all-inorganic interface layer,an initial efficiency exceeding 90%is maintained even after 2,800 h of heating at 85℃.

China & The World Cultural Exchange 2009年第9期75卷 41-43页

作者： xu yazhou

The First Southeast Asia Expo, held in Nanjing in 1910, was the first exposition that China has ever held. The Opium War in 1840 forced China to open its door to Westernpowers. Since then, Western expositions have begun to beknown by Chinese people. The 1876 Philadelphia CentennialExpositionmarkedChina’sfirstofficialparticipationininternationalexpos. China dispatched an official delegation to the expoand installed its exhibition pavilion. In 1904, Zhang Zhenxun, aChinese expatriate merchant returned from southeast Asia,

基于FAST v7开发地震分析和土-结相互作用(soil structure interaction, SSI)模块,形成气动-水动-地震-伺服-土结耦合仿真平台FAST-S,并采用Seismic和ABAQUS验证地震分析模块的计算精度和可靠性。通过扩展的FAST-S平台,建立考虑SSI效应的5 MW近海单桩风机模型,分析风、波浪和地震之间的耦合效应以及研究近场地震动速度脉冲对停机和运行状态下风机支撑结构动力响应的影响。结果表明:地震加剧了塔顶振动,风浪荷载对减轻地震诱发的塔顶振动有一定作用;气动载荷、水动载荷和地震载荷之间存在非线性耦合关系,计算时应充分考虑风-浪-地震耦合效应;近场地震速度脉冲会增大停机和运行状态下风机的塔顶位移、塔顶加速度和泥线处弯矩,结构设计时应注意脉冲型地震动对结构产生的不利影响,特别是停机状态下风机的结构安全。

概率密度演化方法(probability density evolution equation,PDEM)为非线性随机结构的动力响应分析提供了新的途径.通过PDEM获得结构响应概率密度函数(probability density function,PDF)的关键步骤是求解广义概率密度演化方程(generalized probability density evolution equation,GDEE).对于GDEE的求解通常采用有限差分法,然而,由于GDEE是初始条件间断的变系数一阶双曲偏微分方程,通过有限差分法求解GDEE可能会面临网格敏感性问题、数值色散和数值耗散现象.文章从全局逼近的角度出发,基于Chebyshev拟谱法为GDEE构造了全局插值格式,解决了数值色散、数值耗散以及网格敏感性问题.考虑GDEE的系数在每个时间步长均为常数,推导了GDEE在每一个时间步长内时域上的序列矩阵指数解.由于序列矩阵指数解形式上是解析的,从而很好地克服了数值稳定性问题.两个数值算例表明,通过Chebyshev拟谱法结合时域的序列矩阵指数解求解GDEE得到的结果与精确解以及Monte Carlo模拟的结果非常吻合,且数值耗散和数值色散现象几乎可以忽略.此外,拟谱法具有高效的收敛性且序列矩阵指数解不受CFL (Courant-Friedrichs-Lewy)条件的限制,因此该方法具有良好的数值稳定性和计算效率.

采用屈曲模态的线性组合形成初始缺陷构型,假定缺陷幅值服从零均值正态分布,通过拉丁超立方抽样法生成几何初始缺陷样本。进而,采用增量动力分析法获得加速度峰值与罐壁径向位移最大值的关系,并根据Budiansky-Roth准则确定出地震作用下罐壁失稳临界应力值。基于ABAQUS用户单元子程序实现了基于附加质量法的缺陷储油罐地震反应分析。据此,求解出随机地震作用下考虑和未考虑初始几何缺陷的储油罐可靠度。对比分析表明,随着地震作用的增大,罐壁最大压应力离散程度也增大,其概率分布呈现出非正态性,随机初始几何缺陷显著降低了储油罐的抗震可靠度。

规划环境影响评价改革的一项重要内容是与“多规合一”目标下的国土空间规划相衔接。囿于当前国土空间规划与规划环境影响评价在衔接过程中显现出的评价范围不明晰、介入时机晚、分区管控手段冲突、评价技术路线重叠、衔接法律效力较弱等问题,在下一阶段立法中有必要做出回应。通过采取类型化方式确定国土空间规划环境影响评价的范围,建立规划环境影响评价全过程参与国土空间规划的衔接路径和方法以填补立法空白;通过建立部门协同立法模式,明确“三区三线”与“三线一单”的功能衔接以消解立法的冲突;通过明确规划环境影响评价的行政监督属性、建立规划环境影响评价否决权并健全法律责任,以强化规划环境影响评价的法律约束力,并最终实现规划环境影响评价与国土空间规划的有机衔接。
