Nonfullerene organic solar cells(OSCs)have achieved breakthrough with pushing the efficiency exceeding 17%.While this shed light on OSC commercialization,high-performance flexible OSCs should be pursued through solution ***,we report a solution-processed flexible OSC based on a transparent conducting PEDOT:PSS anode doped with trifluoromethanesulfonic acid(CF3SO3H).Through a low-concentration and low-temperature CF3SO3H doping,the conducting polymer anodes exhibited a main sheet resistance of 35Ωsq−1(minimum value:32Ωsq−1),a raised work function(≈5.0 eV),a superior wettability,and a high electrical *** high work function minimized the energy level mismatch among the anodes,hole-transporting layers and electron-donors of the active layers,thereby leading to an enhanced carrier *** solution-processed flexible OSCs yielded a record-high efficiency of 16.41%(maximum value:16.61%).Besides,the flexible OSCs afforded the 1000 cyclic bending tests at the radius of 1.5 mm and the long-time thermal treatments at 85°C,demonstrating a high flexibility and a good thermal stability.

根据熊彼特技术创新理论和现有研究成果,企业技术创新选择的影响因素有财政、金融等外部因素和物质、制度和精神等企业因素。借助问卷数据,分析和检验假设发现财政、金融和劳动力市场等因素对我国企业技术创新作用不明显,企业物质、制度和精神等因素对技术创新选择影响较强,但对不同技术创新的效应差异显著。依据结论建议:在促进经济稳定增长时,政府应激励技术创新;完善投资环境,降低企业开办成本,提升投资者创办企业的积极性,增加企业密度,促进市场竞争;企业应制定长期战略,健全内部制度,协调部门之间利益以激发员工技术创新动力。

Bragg filters are of essential importance for chip-scale photonic ***,the implementation of filters with sub-nanometer bandwidth and rejection beyond 70 dB is hindered by the high index contrast of the siliconon-insulator platform,which makes filters prone to fabrication *** this paper,we propose to combine coherency-broken cascading architecture and cladding modulation to circumvent the intrinsic *** cascading architecture effectively prevents the accumulation of phase errors,while the cladding modulation offers additional design freedom to reduce the coupling coefficient.A bimodal Bragg filter with a testingequipment-limited rejection level of 74 dB and a 40 dB bandwidth of 0.44 nm is experimentally *** minimum feature size is 90 nm,which significantly relieves the fabrication constraints.

"崩溃边缘论""大锅饭论"和"凭票供应论"是支撑"国有企业效率效益低下论"的"三驾马车"。它们对中国历史和事实进行扭曲性、推断性、延伸性的唯心主义处理,再用封闭主义、双重标准在社会主义公有制、国有企业与效率效益低下之间建立起具有伪经济学性质的因果关系,不仅否定1949—1980年几亿人、几代人、几十年为新中国经济所做的艰苦卓绝的创业性、建设性和积累性发展贡献,而且从根本上否定社会主义公有制、国有企业的制度合理性。唯物主义、整体主义的分析表明,"崩溃边缘"是对事实的扭曲,而"大锅饭"和"凭票供应"则是中国特殊条件、特殊时期产生的特殊经济现象,而非社会主义公有制、国有企业的一般性经济规律(如凭票供应在西方也出现过)。而对这些特殊性的辩证唯物主义和交叉科学分析反过来恰恰证实中国社会主义公有制、国有企业不仅高效率高效益地发展了中国经济,而且成为中国经济改革不可或缺的基础。

从经济学、经济社会学等科学角度看，1981～2005年这一阶段的经济发展是否有利于社会和谐是经济政策决策的科学性、经济行为与价值观的一致性、雇佣-劳资关系下劳动力属性以及社会问题成本这四种变量的函数。这些变量同时又是政府功能定位、行为特征和运行效益的函数。实证分析与对比分析的结果表明，经济发展与社会和谐之间没有简单线性关系。
