| 1 | Comparative study of the net exchange of CO_(2) in 3 types of vegetation ecosystems on the Qinghai-Tibetan Plateau显示文摘Using the eddy covariance method,from 1 July2003 to 30 June 2004, we conducted the observation andanalysis of ecosystem CO2 flux in 3 types of alpine meadowvegetation (Kobresia humilis, Potentilla fruticosa shrub andKobresia tibetica swamp meadows) on the Qinghai-TibetanPlateau. The results show that the Kobresia humilis meadow,the shrub meadow and the swamp meadow’s highest CO2uptake rates are 16.78, 10.42 and 16.57 μmol·m?2·s?1respectively, while their highest CO2 release rates are 8.22,7.73 and 18.67 μmol·m?2·s?1 respectively. The Kobresiahumilis meadow and shrub meadow’s annual atmosphericuptakes are 282 g CO2/m2 and 53 g CO2/m2, respectively,while swamp meadow’s annual atmospheric release is 478 gCO2/m2. This proves that the Kobresia humilis meadow andthe shrub meadow on the Qinghai-Tibetan Plateau haverelatively low potential for CO2 uptake and release comparedto C4 grasslands, a number of lowland grasslands, andforests. Moreover, swamp meadow has relatively high releasepotential. This, in turn, reveals clear differences in carbonsource/sink between different types of vegetation in theQinghai-Tibetan Plateau alpine meadow ecosystem. Thesedifferences are mainly brought by differences in thevegetations’ photosynthetic capacity and soil respiration. | ZHAO Liang LI Yingnian ZHAO Xinquan XU Shixiao TANG Yanhong YU Guirui GU Song DU Mingyuan WANG Qinxue | 2005 | Chinese Science Bulletin2005，50，16： | 34 |

| 4 | Magnesium-based materials in orthopaedics:material properties and animal models显示文摘As a new generation of medical metal materials,degradable magnesium-based materials have excellent mechanical properties and osteogenic promoting ability,making them promising materials for the treatment of refractory bone diseases.Animal models can be used to understand and evaluate the performance of materials in complex physiological environments,providing relevant data for preclinical evaluation of implants and laying the foundation for subsequent clinical studies.To date,many researchers have studied the biocompatibility,degradability and osteogenesis of magnesium-based materials,but there is a lack of review regarding the effects of magnesium-based materials in vivo.In view of the growing interest in these materials,this review briefly describes the properties of magnesium-based materials and focuses on the safety and efficacy of magnesium-based materials in vivo.Various animal models including rats,rabbits,dogs and pigs are covered to better understand and evaluate the progress and future of magnesium-based materials.This literature analysis reveals that the magnesium-based materials have good biocompatibility and osteogenic activity,thus causing no adverse reaction around the implants in vivo,and that they exhibit a beneficial effect in the process of bone repair.In addition,the degradation rate in vivo can also be improved by means of alloying and coating.These encouraging results show a promising future for the use of magnesium-based materials in musculoskeletal disorders. | Xirui Jing Qiuyue Ding Qinxue Wu Weijie Su Keda Yu Yanlin Su Bing Ye Qing Gao Tingfang Sun Xiaodong Guo | 2021 | Biomaterials Translational2021，2，3： | 1 |
