Preliminarily analysis on the eutrophication status was made on the basis of the content of dissolved inorganic nitrogen （DIN）, dissolved inorganic phosphate （PO4-P）, dissolved oxygen（DO） and chemical oxygen demand （COD） as well. The results indicated that in most of the survey area, water quality was in accordance with the 1^st class National Seawater Standard except the average concentration of petroleum hydrocarbon which was beyond the 2^nd class National Seawater Standard. The concentrations of PO4-P as well as DIN were mainly influenced by the runoff or drainage from lands, with a comparatively higher concentration in the coastal areas from the Fushan Bay to the Shilaoren bathing beach. The distribution of eutrophication index （El） showed that part of the survey area was in a state of slight eutrophication The eutrophication was mostly influenced by the land runoff or drainage and related factors. The sea water quality of the Olympic boat-sailing field was fine and just slightly polluted on the whole.展开更多

As a global hallmark event, the Olympics, with their enormous scale, universal attraction for the media and tremendous political significance, have increasingly drawn attention from the researchers. It is obvious that Beijing has been greatly impacted by the 2008 Olympic Games as the host. The event aroused close attention of researchers, especially the problem how the Olympic stadiums and facilities can be utilized after Olympic Games. The paper employed 3 methods to conduct a survey, that is, sending questionnaires to tourists, in- terviewing with government officers, and collecting information about former Olympic Parks from Intemet and lit- eratures. The utilization of former Olympic Parks after Games was summarized and some experiences were refined. Besides, 3 main bodies including government, business operators and visitors which formed basic driving forces to influence the park＇s use were analyzed. At the same time, the paper believes that 3 topics affect the park＇s utilization involving ＇prepare to use＇, ~how to use it＇ and ~how to manage it＇, and Beijing Olympic Park can also follow that thinking and reference in the ft^her practices. Based on it, suggestions are given that Beijing Olympic Park can be planned spatially from 3 layers, the point, line and area, based on their function and infrastructure in the Games, and the area would be shaped as a new urban center with multi-functions while Mega-events and sport events are still the main content of the park.展开更多

Meanwhile there also exists a lack or vacancy of English teaching in English teaching at home. The failure of expressing Chinese culture and conditions correctly and fluently among the English learners has already resulted in negative impact on our international image, which is related to our teaching policy of strengthening western culture and neglecting the export of our own culture. Therefore, in the English teaching at all levels, great attention should be paid to the cross-cultural communication between home culture and the culture of target language, the promotion of expressing mother culture in foreign languages, and exporting and broadcasting Chinese culture.展开更多

Wrestling has unique position among Olympic disciplines in India, from being provider of first individual medal to newly independent nation to lately becoming most significant contributor in medal tally. This coming of age of Indian wrestling team with double medal tally in the last Olympics has been outcome of long and steady journey of Indian wrestling team over a period of 40-50 years and numerous Summer Olympic Games. However, this journey of Indian wrestling team in the Olympics is also a stoW of significant twist and turn, near misses and also of glow. So this article covers the entire saga of Indian wrestlers at highest sporting event of world--Olympic Games, from inception of first Indian team of mere three grapplers to latest Olympics with debut of first Indian female grappler in Olympic arena. This history is written by sweat and hard work of Indian grapplers with its own highs and lows.展开更多

To investigate the effects of SO2 and NOx reductions on the particulate sulfate and nitrate concentrations as well as their size distributions, size-segregated aerosol samples were collected using micro-orifice uniform deposit impactors （MOUDIs） at urban and downwind rural sites in Beijing before and after full-scale controls. During the sampling period, the mass concentrations of fine particles （PMI.s） at the urban and rural sites were 94.0 and 85.9 p.g m-3, respectively. More than 90% of the sulfates and 60% of nitrates formed as fine particles. Benefiting from the advantageous meteorological conditions and the source controls, sulfates were observed in rather low concentrations and primarily in condensation mode during the Olympics. The effects of the control measures were separately analyzed for the northerly and the southerly air-mass-dominated days to account for any bias. After the control measures were implemented, PM, sulfates, and nitrates were significantly reduced when the northerly air masses prevailed, with a higher percentage of reduction in larger particles. The droplet mode particles, which dominated the sulfates and nitrates before the controls were implemented, were remarkably reduced in mass concentration after the control measures were implemented. Nevertheless, when the polluted southerly air masses prevailed, the local source control measures in Beijing did not effectively reduce the ambient sulfate concentration due to the enormous regional contribution from the North China Plain.展开更多

Six carbonyls, including formaldehyde, acetaldehyde, acetone, butyraldehyde, valeraldehyde, and hexaldehyde, were identified in all air samples. The total average concentrations of these carbonyls before, during, and after traffic restriction were （48.1 ± 15.2）, （36.6 ± 14.5） and （23.4± 12.3） μg/m^3, respectively. Compared with the period after traffic restriction, the distinct high concentrations of the carbonyls before and during traffic restriction were primarily ascribed to the remarkable contribution of photochemical reactions. With respect to our previous investigation in the summer of 2005, the reductions of formaldehyde, acetaldehyde and acetone during traffic restriction period were about 64%, 47% and 27%, respectively, indicating that the air cleaning actions adopted by the Chinese government for the two games were efficient. The lowest levels of atmospheric carbonyls and the extremely high composition proportion of acetone after the traffic restriction were mainly attributed to the long-term effect of the control measures for the two games.展开更多

The results of this monitoring show that high concentrations of PM2.5 pollution exhibited a regional pattern during the monitoring period （1 June-30 October 2008）. The PM2.5 mass concentrations were 53 μg m-3, 66 p.g m-3, and 82 μg m-3 at the background site, in Beijing, and in the Beijing-Tianjin-Hebei urban agglomerations, respectively. The PM2.5 levels were lowest during the 2008 Olympic Games （8-24 August）： 35μg m-3 at the background site, 42 μg m-3 in Beijing and 57 μg m-3 in the region. These levels represent decreases of 49%, 48% and 56%, respectively, compared to the prophase mean concentration before the Olympic Games. Emission control measures contributed 62% 82% of the declines observed in Beijing, and meteorological conditions represented 18%-38%. The concentration of fine particles met the goals set for a ＂Green Olympics.＂展开更多

文摘What happened to the Olympic torch relay abroad reveals how little and superficially the western countries, in particular, know of china. Meanwhile there also exists a lack or vacancy of English teaching in English teaching at home. The failure of expressing Chinese culture and conditions correctly and fluently among the English learners has already resulted in negative impact on our international image, which is related to our teaching policy of strengthening western culture and neglecting the export of our own culture. Therefore, in the English teaching at all levels, great attention should be paid to the cross-cultural communication between home culture and the culture of target language, the promotion of expressing mother culture in foreign languages, and exporting and broadcasting Chinese culture.

文摘Wrestling as an Olympic sport has been around since the dawn of modem Olympic games and India is a participating nation in it. Wrestling has unique position among Olympic disciplines in India, from being provider of first individual medal to newly independent nation to lately becoming most significant contributor in medal tally. This coming of age of Indian wrestling team with double medal tally in the last Olympics has been outcome of long and steady journey of Indian wrestling team over a period of 40-50 years and numerous Summer Olympic Games. However, this journey of Indian wrestling team in the Olympics is also a stoW of significant twist and turn, near misses and also of glow. So this article covers the entire saga of Indian wrestlers at highest sporting event of world--Olympic Games, from inception of first Indian team of mere three grapplers to latest Olympics with debut of first Indian female grappler in Olympic arena. This history is written by sweat and hard work of Indian grapplers with its own highs and lows.

文摘For the 2008 Olympic Games, drastic control measures were implemented on industrial and urban emissions of sulfur dioxide （SO2）, nitrogen oxides （NOx） and other pollutants to address the issues of poor air quality in Beijing. To investigate the effects of SO2 and NOx reductions on the particulate sulfate and nitrate concentrations as well as their size distributions, size-segregated aerosol samples were collected using micro-orifice uniform deposit impactors （MOUDIs） at urban and downwind rural sites in Beijing before and after full-scale controls. During the sampling period, the mass concentrations of fine particles （PMI.s） at the urban and rural sites were 94.0 and 85.9 p.g m-3, respectively. More than 90% of the sulfates and 60% of nitrates formed as fine particles. Benefiting from the advantageous meteorological conditions and the source controls, sulfates were observed in rather low concentrations and primarily in condensation mode during the Olympics. The effects of the control measures were separately analyzed for the northerly and the southerly air-mass-dominated days to account for any bias. After the control measures were implemented, PM, sulfates, and nitrates were significantly reduced when the northerly air masses prevailed, with a higher percentage of reduction in larger particles. The droplet mode particles, which dominated the sulfates and nitrates before the controls were implemented, were remarkably reduced in mass concentration after the control measures were implemented. Nevertheless, when the polluted southerly air masses prevailed, the local source control measures in Beijing did not effectively reduce the ambient sulfate concentration due to the enormous regional contribution from the North China Plain.

文摘BACKGROUND:Beijing 2022 Olympic Winter Games was the second Games held amid the COVID-19 pandemic.To a certain extent,it has altered the way sporting activities operate.There is a lack of knowledge on injury risk and illness occurrence in elite winter sport athletes amid the COVID-19 pandemic.This study aimed to describe the incidence of injuries and illnesses sustained during the XXIV Olympic Winter Games in Beijing from February 4 to 20,2022.METHODS:We recorded the daily number of injuries and illnesses among athletes reported by Beijing 2022 medical staff in the polyclinic,medical venues,and ambulance.We calculated injury and illness incidence as the number of injuries or illnesses occurring during competition or training,respectively,with incidence presented as injuries/illnesses per 100 athlete-days.RESULTS:In total,2,897 athletes from 91 nations experienced injury or illness.Beijing 2022 medical staff reported 326 injuries and 80 illnesses,equaling 11.3 injuries and 2.8 illnesses per 100 athletes over the 17-day period.Altogether,11%of the athletes incurred at least one injury and nearly 3%incurred at least one illness.The number of injured athletes was highest in the skating sports(n=104),followed by alpine skiing(n=53),ice track(n=37),freestyle skiing(n=36),and ice hockey(n=35),and was the lowest in the Nordic skiing disciplines(n=20).Of the 326 injuries,14(4.3%)led to an estimated absence from training or competition of more than 1 week.A total of 52 injured athletes were transferred to hospitals for further care.The number of athletes with illness(n=80)was the highest for skating(n=33)and Nordic skiing(n=22).A total of 50 illnesses(62.5%)were admitted to the department of dentistry/ophthalmology/otolaryngology,and the most common cause of illness was other causes,including preexisting illness and medicine(n=52,65%).CONCLUSION:Overall,11%of athletes incurred at least one injury during the Games,which is similar to the findings during the Olympic Winter Games in 2014 and 2018.Regarding illness,2%of athletes were affected,which is approximately one-third of the number affected in the 2018 Olympic Winter Games.

文摘The measurements of atmospheric carbonyls concentrations in Beijing were conducted from 12 July to 8 October, 2008, covering the periods of the 2008 Olympic Games and Paralympic Games. Six carbonyls, including formaldehyde, acetaldehyde, acetone, butyraldehyde, valeraldehyde, and hexaldehyde, were identified in all air samples. The total average concentrations of these carbonyls before, during, and after traffic restriction were （48.1 ± 15.2）, （36.6 ± 14.5） and （23.4± 12.3） μg/m^3, respectively. Compared with the period after traffic restriction, the distinct high concentrations of the carbonyls before and during traffic restriction were primarily ascribed to the remarkable contribution of photochemical reactions. With respect to our previous investigation in the summer of 2005, the reductions of formaldehyde, acetaldehyde and acetone during traffic restriction period were about 64%, 47% and 27%, respectively, indicating that the air cleaning actions adopted by the Chinese government for the two games were efficient. The lowest levels of atmospheric carbonyls and the extremely high composition proportion of acetone after the traffic restriction were mainly attributed to the long-term effect of the control measures for the two games.

文摘The Atmospheric Environmental Monitoring Network successfully undertook the task of monitoring the atmospheric quality of Beijing and its surrounding area during the 2008 Olympics. The results of this monitoring show that high concentrations of PM2.5 pollution exhibited a regional pattern during the monitoring period （1 June-30 October 2008）. The PM2.5 mass concentrations were 53 μg m-3, 66 p.g m-3, and 82 μg m-3 at the background site, in Beijing, and in the Beijing-Tianjin-Hebei urban agglomerations, respectively. The PM2.5 levels were lowest during the 2008 Olympic Games （8-24 August）： 35μg m-3 at the background site, 42 μg m-3 in Beijing and 57 μg m-3 in the region. These levels represent decreases of 49%, 48% and 56%, respectively, compared to the prophase mean concentration before the Olympic Games. Emission control measures contributed 62% 82% of the declines observed in Beijing, and meteorological conditions represented 18%-38%. The concentration of fine particles met the goals set for a ＂Green Olympics.＂
