我国淡水贝类资源丰富、种类繁多,有记录的淡水贝类目前已经超过470种,广泛分布于我国各地的湖泊、河流和山间湿地等生态系统中。其中我国特有种贝类在各主要分布水系的比例均高于50%,特有种质资源十分丰富。淡水贝类不仅在生态系统中扮演着重要的角色,而且具有巨大的经济价值。淡水珍珠蚌中三角帆蚌和褶纹冠蚌,以及一些食用贝类如中华圆田螺、螺蛳、河蚬等的资源开发比较充分,但是由于淡水贝类分布范围广、栖息环境多样,相对于其他一些淡水贝类,目前研究还仅限于资源调查和物种鉴定层面。整体上,国内淡水贝类的种质资源评估不够系统,保护和开发利用未得到足够重视。本文就我国淡水贝类物种多样性与区域分布、淡水贝类种质资源可持续开发与利用情况、引进淡水贝类种质资源与利用现状及淡水贝类种质资源现行保护措施进行概述,并提出有关淡水贝类种质资源保护和可持续利用的建议,以期促进我国淡水贝类资源保护和开发利用协同发展。

Although Optical character recognition(OCR) technology has achieved huge progress in recent years, character misrecognition is inevitable. In order to realize high fidelity content of document digitalization,we propose a new Convolutional neural networks(CNN)based confidence estimation method. We detect the misrecognized characters through comparing the confidence value with a preset threshold, so as to leave the recognition errors as embedded images in the output digital documents. We adopted sofmax as the estimation of posteriori probability,overlap pooling and maxout with dropout technologies in CNN architecture design. Experimental results show that our method has achieved an explicit improvement compared to baseline system.

By using scanning tunneling microscopy(STM)/spectroscopy(STS), we systematically characterize the electronic structure of lightly doped 1 T-TiSe_2, and demonstrate the existence of the electronic inhomogeneity and the pseudogap state. It is found that the intercalation induced lattice distortion impacts the local band structure and reduce the size of the charge density wave(CDW) gap with the persisted 2 × 2 spatial modulation. On the other hand, the delocalized doping electrons promote the formation of pseudogap. Domination by either of the two effects results in the separation of two characteristic regions in real space, exhibiting rather different electronic structures. Further doping electrons to the surface confirms that the pseudogap may be the precursor for the superconducting gap. This study suggests that the competition of local lattice distortion and the delocalized doping effect contribute to the complicated relationship between charge density wave and superconductivity for intercalated 1 T-TiSe_2.

本工作旨在探究粉胶比对煤直接液化残渣(Direct coal liquefaction residue,DCLR)复合改性沥青胶浆及混合料低温性能的影响。设计了四种粉胶比(0.6、0.8、1.0、1.2)下三种沥青胶浆及混合料(SK-90沥青胶浆及混合料、DCLR改性沥青胶浆及混合料、DCLR复合改性沥青胶浆及混合料),采用弯曲蠕变劲度(BBR)试验、低温小梁试验、半圆弯曲(SCB)试验、接触角试验进行性能评价。试验结果表明:相比于DCLR改性沥青胶浆及混合料,DCLR复合改性沥青胶浆临界破坏温度显著降低,混合料破坏应变提升较大,基本上达到SK-90沥青胶浆及混合料的低温性能水平。综合各种试验结果,三种混合料粉胶比为1.0时的低温性能最优。尤其是DCLR复合改性沥青混合料在粉胶比为1.0时,表现出更好的低温应力松弛能力,较强的抗开裂能力与抗裂缝发展能力。但其受粉胶比变化敏感性较强,当粉胶比增加到1.2时,混合料低温抗开裂能力与抗裂缝发展能力显著降低。
