| 1 | Comparison on conjunctival sac bacterial flora of the seniors with dry eye in Ganzi autonomous prefecture显示文摘AIM:To compare the bacterial flora in palpebral conjunctiva of xerophthalmia seniors of Tibetan,Yi and Han,and analyze the differences and similarities of the bacteria.·METHODS:The test subjects were selected from 2Tibetan,2 Yi and 3 Han populated places,respectively.Total 222 seniors(444 eyes) with dry eye were examined.Secretion was collected from the palpebral conjunctiva of the subjects and then inoculated onto a blood agar plate.After 48h of incubation,the bacteria were examined for the differences and similarities between different ethnics.·RESULTS:There was no significant difference(P >0.05)of Gram stain characterization,dominant bacteria and number of the bacterial species present in oxrophthalmia patients among Tibetan,Yi and Han nationalities.The bacteria presented in all groups include staphylococcus epidermidis,corynebacterium,micrococcus luteu,int-racellular bacteria sphingomonas,pseudomonas aerug-inosa.The bacteria detected from the two of three ethnic groups were staphylococcus aureus,staphylococcus haemolyticus,escherichia coli,kytococcus sedentarius,streptococcus angina,micrococcus lylae,and staphy-lococcus heads.The incidence rate of bacteria-associated dry eye in Tibetan population was significantly lower than that of Han and Yi population.·CONCLUSION:There is no significant difference in the bacteria flora of palpebral conjunctiva observed among dry eye elder populations of Tibetan,Yi and Han people.All of staphylococcus epidermidis,corynebacterium,micrococcus luteu,intracellular bacteria sphingomonas,pseudomonas aeruginosa,staphylococcus aureus,staphylococcus haemolyticus,escherichia coli,kytococcus sedentarius,streptococcus angina,micrococcus lylae and staphylococcus heads are common bacteria flora of the three nationalities inhibiting in this area. | Yue Zhang Zhi-Rong Liu Hui Chen Ying-Chuan Fan Ji Duo Hong Zheng Guang-Jin Wang Yu-Chan Li Dan-Ba Jiachu Ge-Ma Zewang | 2013 | International Journal of Ophthalmology(English edition)2013，6，4： | 4 |

| 6 | ACTIVATION OF TRICOBALT CLUSTERS AND SYNTHESIS OF TRICOBALT CLUSTERS CONTAINING PHOSPHINE LIGANDS显示文摘A successful method of activation, in which trimethylamine oxide is used to activate the tricobalt carbonyl clusters at room temperature, has been reported in this paper. A series of tricobalt clusters containing monodentate phosphine ligand PPh3 and bidentate phosphine ligand dppm (bis(diphenylphosphino)methane) have also been synthesized by making use of the quasi-coordinatively unsaturated clusters (μ3-CR)Co3(CO)9-n(MeCN)n(R=Me, Ph, H, Cl,n=1, 2). The structures of these clusters reported in this paper have been characterized by IR, NMR and MS. | Liu Jiachu, Wang Weibin, Cong Aizhen, Lu Getan, Lin Xiuqin(Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Fuzhou, Fujian, 350002, China) | 1990 | 分子催化1990，4，S1： | 0 |
| 7 | Energy Absorption Characteristics of a Novel Asymmetric and Rotatable Re-entrant Honeycomb Structure显示文摘Based on the symmetric re-entrant honeycomb(S-RH)structure with negative Poisson’s ratios,a novel asymmetric and rotatable re-entrant honeycomb(AR-RH)structure was proposed.Both the S-RH structure and AR-RH structure were produced by the 3D printing technology.Through experimental test and finite element simulation,the deformation mechanism and energy absorption characteristics of the AR-RH structure and the S-RH structure with negative Poisson’s ratios at different impact velocities were compared.The experimental test and finite element simulation results show that the novel AR-RH structure with negative Poisson’s ratios has stronger energy absorption capacity than the S-RH structure,and it has been verified that the rotatability of AR-RH can indeed absorb energy.Furthermore,the degree of asymmetry of the AR-RH structure was discussed. | Huifeng Xi Jiachu Xu Shende Cen Shiqing Huang | 2021 | Acta Mechanica Solida Sinica2021，34，4： | 0 |
| 8 | Buckle Propagation in Steel Pipes of Ultra-high Strength:Experiments,Theories and Numerical Simulations显示文摘In this paper,experimental,theoretical and numerical approaches were employed to scrutinize the buckle propagation events occurring in pipes subjected to external pressure.Two groups of samples with different radius-to-thickness ratios were fabricated using steel pipes of ultra-high strength and were subjected to compression of external pressure in a sealed pressure vessel specially designed and customized for the experiment.Experimental results were recorded through a data acquisition system.For facilitating the theoretical calculations,uniaxial tensile tests were performed on tensile pieces cut from the same pipes to obtain the material properties.It was found from the experimental results that once a buckle is initiated in a pipe,the external pressure dropped to a specific value called buckle propagation pressure and kept at this level until the whole pipe is flattened into a dog-bone shape.Based on the measured material properties and geometric parameters,theoretical solutions were computed using established ring models and shell model,and finite element predictions were also obtained from ABAQUS software.The efficiency and accuracy of the shell model and finite element model were expounded by comparing various theoretical solutions and numerical predictions with the experimental results.With the authenticated shell model and finite element model,a deep insight into the phenomenon of buckle propagation of pressurized long pipes was provided by performing a series of parametric study. | Haofeng Liang Jiahui Zhou Jixin Lin Fusong Jin Fei Xia Jianghong Xue Jiachu Xu | 2020 | Acta Mechanica Solida Sinica2020，33，4： | 0 |
