Low-rank quaternion recovery(LRQR) can effectively utilize the correlation between the RGB channels in color image ***,the underlying low-rank structure of image relies on the patch-level non-local self-similarity(NSS),whose accuracy needs to be further *** our paper,we propose a pixel-level NSS method based on the patch-level NSS to more accurately capture the underlying low-rank structure of quaternion-encoded color ***,we propose a row matching method that performs fine screening on the basis of patch-level similar groups to obtain pixel-level similar groups,and then perform LRQR on them based on the Laplace *** also propose a weighted aggregation method to measure the contribution of recovery effects of different *** on synthetic noise images and real noise images show that when the noise variance is 10,30,and 50,our proposed method increases at least 0.32 dB,0.62 dB,and 0.58 dB on the average of PSNR,respectively.

[目的/意义]近年来社交网络已经成为人们普遍使用的分享传播信息的媒介。随着社交网络的不断膨胀,传统的社交网络模型与现实网络情况的契合度逐渐减弱。文章通过建模仿真对传统模型进行优化和检验,以期为有关部门有效应对和预测社交网络动向提供参考。[方法/过程]文章以经典社交网络模型为基础,融入空间要素进行优化,并在随机图中逐渐增加节点数量以构建成长型社交网络模型,最后利用MATLAB等软件实现模型和数值仿真验算。[结果/结论]实验结果显示:空间距离要素对社交网络节点间关系的变化存在较大影响,且其影响在某些情景下高于关系强度;而基于纯空间要素与纯关系要素的网络都不会使得节点产生很高的聚类反映,但当其两者以一定比例融合后,节点链接概率将大幅上升;该研究所建成长型社交网络模型相比于传统模型与真实社交网络具有更高的拟合度。

对于《魏武帝集》结集时间以及著录情况的考察,有助于更为全面地理解文本。就现有文献,《魏武帝集》初次结集为三十卷,时间上限为梁普通四年(523),但不会晚于大同二年(536);后有隋二十六卷,唐三十卷,宋三十卷,明五卷,清一卷本。由隋至清的著录可以看出《魏武帝集》自结集之后,一直在流传,并未全部亡佚,只是在作品数量上大量减少。

China’s manganese resources are usually associated with the valuable elements such as silver, lead, zinc, cobalt, nickel, scandium, etc which should be comprehensively recovered during the manganese beneficiation. A manganese ore from western China contains Mn 23.18%, Co 0.073%, Ni 0.21% and Sc 0.013%. The mineralogy composition of ore and the occurrence of associated elements of Sc, Co as well as Ni are studied in this paper. According to the results, the manganese minerals in this ore are mainly lithiophorite and a little secondary pyrolusite. The lithiophorite in this ore is rich in aluminum and actually it is the generic name for the multi-mineral aggregates mixed by silicon, aluminum and iron, which is quite different with the ordinary psilomelane. There is not any Sc, Ni or Co mineral in this ore and more than 98% of Sc, Ni and Ni exists in lithiophorite and pyrolusite. The distribution of Sc, Co and Ni in lithiophorite is further studied by EPMA and the results indicate that Sc and Co in lithiophorite is sparse and dispersed distribution while Ni usually distributes in the argillaceous lithiophorite and is local enrichment. Reduction-sulfuric acid leaching tests show that the dissolution of Sc and Co happens before lithiophorite dissolves; the dissolution rate of Sc and Co is almost the same, which is significantly higher than the dissolution rate of manganese. However, the dissolution rate of Ni is extremely low with the dissolution of manganse, which indicates that Ni is hard to dissolve and its dissolution rate obviously lags behind that of Mn, Sc and Co. The conclusion can be drawn that Sc and Co exist in the lithiophorite crystals as interface adsorption while Ni exists in the clay (kaolinite) mixed up with lithiophorite as interface adsorption. The conclusion indicates that Sc and Co can dissolve before the dissolution of manganese at a high dissolution rate in the hydrometallurgical process while Ni is also into the solution through desorption from the

北方地区冬季结冰与春季融化引起土的冻胀和融沉问题,弱化了土的抗压性能。以研究冻融循环对固化盐渍土抗压性能的影响为目的,完成冻融前后盐渍土、石灰固化盐渍土、石灰+SH固化盐渍土的抗压试验。结果表明:盐渍土、石灰固化土和石灰+SH固化土的抗压强度随冻融次数的增加而减小,石灰+SH固化土的抗压强度均高于另2种土;冻融前后石灰固化土和石灰+SH固化土均为应变软化型,盐渍土则由应变软化型转变为应变硬化型。冻融循环次数相同时,石灰+SH固化土的抗压强度随含水率的增加而减小,其应力–应变曲线逐渐趋于平缓,土的脆性减弱。石灰+SH固化土具有相对较好的抗冻融性能,含水率是影响冻融后土的抗压性能的首要因素。

淮南书局重刻《十三经注疏》是经何绍基提议,在曾国藩、方浚颐的支持下,以何绍基、莫友芝为中心,汇集淮南书局编校士人群体共同展开的工程。自同治十年春筹备校刻,至光绪四年刊成《毛诗注疏》一种而罢,淮南书局重刻《十三经注疏》未竟而殇,其直接原因是书局人事变故所致,更深层原因则在于同光年间学术风气的转变。淮南书局重刻《十三经注疏》作为偶发性挫折事件,为考察晚清经学与学术衍变提供了一个独特视角,从中既能看到晚清经学的延续与学者的固守,也真切映照出经学渐趋衰落的时代变迁。
