We have synthesized two photovoltaic molecules（HEX-3TVT-ID and EH-3TVT-ID） based on vinylenebridged oligothiophene applied as donor for the solution-processable bulk-heterojunction organic solar cells（OSCs）. Vinylene unit was introduced as π-bridge in the oligothiophenes with 1,3-indenedione as end group and 4,4’-dihexyl-2,2’：5’,2’-terthiophene or 3’,4’-di（octan-3-yl）-2,2’：5’,2’-terthiophene as core,respectively. Due to the different substituent positions of the alkyl group relative to the vinylene unit in the terthiophene, HEX-3TVT-ID and EH-3TVT-ID show different optical and electrochemical properties, corresponding to the photovoltaic performance of the OSCs devices. The power conversion efficiency（PCE） of the OSCs based on a blend of HEX-3TVT-ID and PC71BM（1：0.8, weight ratio, 0.5% CN） reached 2.3%. In comparison, the OSCs based on the blend of EH-3TVT-ID and PC71BM in the weight ratio of 1：1 without the additive show a higher PCE of 2.7%, with a typically high VOC of 0.93 V, under the illumination of AM 1.5, 100 mW cm-2.

为了帮助智能汽车快速识别前方的交通标志，提升汽车在交通道路上的行驶安全，针对现有技术在识别过程中容易出现误检和漏检的问题，在优化现有SSD(Single Shot MultiBox Detector)目标检测模型的基础上，提出一种新的检测模型Rep-SSD(Re-parametrization, SSD),保证网络的实时性和识别的准确性.为增强骨干网络的特征提取能力，将SSD骨干网络中的卷积层更换为重参数化卷积层，在训练过程加入多分支结构增强网络特征的提取能力，在推理过程中采用重参数化技术简化网络，保持网络的识别速度.为进一步增强改进网络的小目标识别能力，加入CBAM(Convolutional Block Attention Module)注意力机制，强化网络提取到的特征信息.试验结果表明：在德国交通标志识别数据集GTSRB上，Rep-SSD模型的检测精度达到84.7%,检测速度(FPS)达到110帧每秒，模型具有较好的检测精度和实时性.所提出的Rep-SSD模型为自动驾驶汽车提供了一种实时且准确的交通标志识别方案.
