Research progress on the influence of maintenance and management on the playing quality of soccer fields;
养护管理对足球场草坪运动质量影响的研究进展
The playing quality of turf in the Beijing Workers′ Stadium was investigated in the game season of 1996.
结果表明大多数质量指标已达到国际标准，而土壤物理性状的奠定和改良对于改善和维持草坪运动质量起着关键性作用；在保证这些质量标准的前提下，为延长绿期而改变草种组成有较大的余地；分析了在我国推广质量标准的可能性。
Athletes can change a wobbling mass to a stiffness mass by increasing their muscular stress and then modifying their movement frequency to adapt to the equipment s vibration frequency,and so achieve resonance effects.
运动员可以在一定范围内通过改变肌肉紧张度使人体的晃动质量变为硬质量,从而调节动作频率,以适应器械(如跳水跳板,单、双杠等)的振动频率,取得共振的效果。
Combining with the work of Dominguez,Gend and Paver,we reconstructed the spectral function below the threshold by the sum of two Breit-Wigner form resonances,we obtained s(1 GeV)=219 MeV,where s is the running mass of the strange quark.
结合Dominguez,Gend和Paver的工作,重新考虑渐近自由阈以下的谱函数后,计算了s夸克的质量,得到s夸克的跑动质量-ms(1 GeV)=219 MeV。
