| 1 | 加热环境对人工合成磁赤铁矿热磁行为的影响显示文摘热磁测量,包括高温磁化率和高温磁化强度测量,是根据热磁曲线转折点的温度(居里点、尼尔点或相变点)鉴定样品中磁性矿物种类的有效方法.本文选取两个人工合成磁赤铁矿样品,利用四种热磁测量仪器分析不同的条件下测得的热磁曲线.依据样品与空气接触程度,将测量环境设为开放、封闭、封闭(通入氩气或氮气)三类.结果表明:热磁测量环境的开放程度对居里点和曲线可逆程度产生极大的影响.封闭环境下测得的居里点较开放环境下的低,分别对应磁铁矿和磁赤铁矿;开放系统的热磁曲线不可逆程度高于封闭系统.造成这些差异的原因是氧化还原条件的不同.本文的磁赤铁矿样品在封闭的条件下,加热至250℃左右开始转化为磁铁矿,因此无法通过居里点被正确识别;在开放的氧化环境下,加热的最终产物为赤铁矿,能够测得正确的居里点.本实验结果启发人们:在不同的加热环境下,磁性矿物可能表现出不同的热磁行为,根据单一的热磁曲线,很容易对样品中磁性矿物的种类造成误判.全面对比不同条件下的测量结果,才能够得出更为准确的结果. | 刘秀铭 吕镔 李平原 Field Russell 毛学刚 郭晖 马明明 赵国永 | 2013 | 地球物理学报2013，56，5： | 10 |

| 16 | The demands of the extra-time period of soccer:A systematic review显示文摘Background:Soccer match-play is typically contested over 90 min;however,in some cup and tournament scenarios,when matches are tied,they proceed to an additional 30 min,which is termed 'extra-time^(ET).This systematic review sought to appraise the literature available on 120-min of soccer-specific exercise,with a view to identifying practical recommendations and future research opportunities.Methods:The review was conducted according to the PRISMA guidelines.Independent researchers performed a systematic search of PubMed,CINAHL,and PsycINFO in May 2019,with the following keywords entered in various combinations:'soccer','football','extra-time','extra time','extratime','120 minutes','120 min','additional 30 minutes',and 'additional 30 min'.Results:The search yielded an initial 73 articles.Following the screening process,11 articles were accepted for analyses.Articles were subsequently organized into the following 5 categories:movement demands of ET,performance responses to ET,physiological and neuromuscular response during ET,nutritional interventions,and recovery and ET.The results highlighted that during competitive match-play,players cover5%-12% less distance relative to match duration(i.e.,meters per minute) during ET compared to the preceding 90 min.Reductions in technical performance(i.e.,shot speed,number of passes and dribbles) were also observed during ET.Additionally,carbohydrate provision may attenuate and improve dribbling performance during ET.Moreover,objective and subjective measures of recovery may be further compromised following ET when compared to 90 min.Conclusion:Additional investigations are warranted to further substantiate these findings and identify interventions to improve performance during ET. | Adam Field Robert Joseph Naughton Matthew Haines Steve Lui Liam David Corr Mark Russell Richard Michael Page Liam David Harper | 2022 | Journal of Sport and Health Science2022，11，3： | 0 |
