Solar-driven CO_(2)conversion to prepare value-added products is highly desirable but *** to the achievement of multi-carbon products via CO_(2)photoconversion is to break the bottlenecks of C-C coupling and multi-electron ***,a charge relay system consisting of Pd-decorated BiOCl-wrapped CuBi_(2)O_(4)is reported by taking advantage of the synergy of Pd nanoparticles(PdNPs)and heterojunction for efficient CO_(2)-to-C_(2)H_(6)*** C_(2)H_(6)production rate reached 167.1µmol g^(-1)h^(-1)with the electron selectivity of 81.1%in the absence of any sacrificial *** spectroscopic characterizations indicated that BiOCl nanosheets,acting as the charge relay,directionally transferred the photogenerated electrons from itself and CuBi2O4 nanorods to PdNPs for C-C *** coordinated ensemble of PdNPs and heterojunction significantly elevated the charge separation and transfer ***,the in-situ spectroscopic analysis supported by theoretical simulations demonstrated that the electron-rich PdNPs generated by the charge relay of PdNPs and heterojunction optimized the CO_(2)-to-C_(2)H_(6)reaction pathway and reduced the energy barrier of the key*CHOCO *** work develops an innovative strategy to design the multifunctional catalysts for the photoconversion of CO_(2)to value-added carbon products.

空间三维重建在遥感、军事、航空航天等多种领域均有着重要应用。其中，光场成像技术被广泛应用，为了使三维重建更精确，需要对光场成像的每个平面清晰成像。因此，提高光场图像的像质是解决空间重建的关键。首先，将光场成像应用于空间成像系统中，建立基于波动光学的光场成像模型，降低了成像模型复杂性，仿真出光场原始图像。其次，根据光场数字重聚焦算法，进行数字调焦，得到不同对准平面处的光场图像。最后，由于相对运动造成的误差、数字重聚焦算法存在的一定误差和微透镜阵列在光路中成像造成中高频信号损失等因素，重聚焦图像模糊。现有的图像去模糊算法并不能满足光场成像技术所需的像质要求，因此，本文提出一种去除遥感光场重聚焦图像模糊的算法。该算法利用图像模糊会导致局部最小强度值变大和局部最大梯度值变小的先验知识，通过构建能量函数，使用改进的半二次分裂方法估计潜在图像和模糊核，以达到去模糊的目的。结果表明，所提算法在处理光场重聚焦图像上优于其他图像去模糊算法。

Factors affecting micro-graft in vitro were studied in persimmon lines of Jiro,Nishimarawase,Zenjiomaru,Okitsu-20,Xinqiu,Maekawa Jiro and Youhou. The results indicated that higher survival rate was obtained when using the plantlets sub-cultured for 30 d with vigorous adventitious shoots. The best moisturepreserving material was the tampon ＋ parafilm. The optimal medium was（ 1/2 N） MS ＋ BA 3. 0 mg/L ＋ IAA 0. 1 mg/L ＋ sugar 30. 0 g/L ＋ agar 6. 0 g/L,and the graft survival rate was up to 40%.
