对快乐体育教学的几点思考     

陆宝 《桂林师范高等专科学校学报》2004,18(4):79-81

在旧的大学公共体育教学目标、教学大纲、教师的教学方法等因素的综合作用下，大学公共体育课显得郁闷而无生气。其弊端与误区在于：1．以一个标准要求不同的人；2．以较为标准的动作要求非体育专业的学生；3．忽视学生的主体性，泯灭学生自觉学习的动力；4．课堂组织呈现“机械化”刻板、单调；5．学生“为教而学”或为“考试而学”，而不是“为己而学”等等。郁闷的公共体育课挫伤了一部分学生的积极性，体育课的其他功能(如文化性、娱乐性、品德教育等)得不到应有的发挥。因此，必须改革现有的公共体育课，改革的第一步，就是使之成为快乐教学课，让更多的学生喜欢体育课和参与课外运动，并逐渐形成大学生体育教育文化。  相似文献   

Infrared Absorption Spectra of Serpentine Cat＇s Eye from Sichuan Province of China     

LU Bao - qi 《上海大学学报(英文版)》2005,9(4):365-368

Infrared （IR） absorption spectra and X-ray powder diffraction （XRD） patterrns of sexpenfine cat＇s eye from Sichuan Province have been investigated, and infrared absorption bands of the serpentine have been assigned in this paper. The results indicate that the bands near 3 600 - 3 700 cm^-1 belong to the stretching absorption band VOH, the bands in 948 - 1 100 cm^-1 axe assigned to the stretching vibraling band Usvo, and the bands at 600 570 and 440 cm^-1 respectively belong to the bending vibration band VOH, δMg-O and δSi-O. The serpentine cat＇ s eye includes two types： chrysotile and antigorite. Chrysotile has a sharp and intensive band at 3 688 cm^-1 and a weak band at 3 643 cm^-1 , while antigorite has only one intensive band in the region. At vibration band VSi-O, chrysotile and antigorite have a similar feature at 1 071 cm^-1, but the band at 980 cm^-1 in anfigorite has been split into two bands in chrysotile - a strong one at 1 027 cm^-1 and a weak one at 949 cm^-1. In addition, antigorite has a characteristic bending vibrating band δMg-O at 570 cm^-1. Based on the analysis of the feature of crystal structure, their IR differences axe well explained.  相似文献   

Yangxueqingnao particles inhibit rat vascular smooth muscle cell proliferation induced by lysophosphatidic acid   总被引：1，自引：0，他引：1  

Cai W  Xu Y  Chen JZ  Huang SR  Lu ZY  Wang ZK 《Journal of Zhejiang University. Science. B》2005,6(9):892-896

Objective: To observe the effect of Yangxueqingnao particles on rat vascular smooth muscle cell (VSMC) proliferation induced by lysophosphatidic acid (LPA). Methods: The amount of3H-TdR (3H-thymidine) admixed in cultured rat VSMC was measured and mitogen-activated protein kinase (MAPK) activity and lipid peroxidation end product malondialdehyde (MDA)content of the VSMC were assayed. Results: 1×10-9, 1×10-8, 1×10-7 mol/L LPA in a concentration dependent manner, induced the amount of 3H-TdR admixed, MAP kinase activity, and MDA content of the cultured rat VSMC to increase. However, 5%, 10%,and 15% Yangxueqingnao serum preincubation resulted in a decrease of 23.0%, 42.0%, and 52.0% (P＜0.01) respectively in the amount of 3H-TdR admixed, a decline in VSMC MAP kinase activity of 13.9% (P＜0.05), 29.6% (P＜0.01), and 48.9% (P＜0.01)respectively, and also, a decrease in MDA content of VSMC of 19.4%, 24.7%, and 43.2% (P＜0.01) respectively, in the 1×10-7mol/L LPA-treated VSMC. Conclusions: LPA activates the proliferation and lipid peroxidation of VSMC in a concentration dependent manner. The LPA-induced VSMC proliferation is related to the activity of MAP kinases, enzymes involved in an intracellular signalling pathway. The results of the present study showed that Yangxueqingnao particles can effectively inhibit LPA-induced VSMC proliferation, MAP kinase activation, and reduce lipid peroxidative lesion.  相似文献   

Oseen流动中粘性对自由表面波的影响     

卢东强 《上海大学学报(英文版)》2004,8(1):8-12

Based on the complex dispersion relation for the two-dimensional free-surface waves generated by a moving body in the steady Oseen flows, the effect of viscosity on wavelength and wave amplitude was investigated by means of an asymptotic method and a numerical analysis. A comparison between the asymptotic and numerical analysis for the viscous decay factor demonstrates the validity of the perturbation expansions for the wave profile. The numerical result shows that the wavelength of viscous wave is slightly elongated in comparison with that of inviscid wave.  相似文献   

张恨水作品在新闻传媒中的身份确论     

路善全 《池州师专学报》2005,19(6):35-39

张恨水作为报人小说家，其新闻观念与艺术追求之结合、其作品与新闻传媒的结缘，丰富了我国文学史与新闻史的研究；其作品对文学性与新闻性的自觉或不自觉的契合和嫁接，确立了张恨水作品在新闻传媒中的身份；在二十世纪上半期的中国，无论是张恨水选择了新闻传媒，抑或是新闻传媒选择了张恨水，都是偶然中的一种历史必然。  相似文献
