苗族鼓舞是苗族文化一个侧面的反映,具有典型的艺术模式和文化特征。苗族鼓舞与苗族其他艺术形式一样,构成了独特的苗族文化生态群落。在苗族历史发展过程中,原始的“巫”文化与民族艺术经过了多层面、多方位的融合,苗族鼓舞成为了反映苗族文化内容与特征的主要形式。 相似文献

"你们亲自到我们村委会举办拖拉机驾驶员培训班、上门为我们办理拖拉机落户,太方便了,我们太高兴了,谢谢你们。"近日,云南省武定县吆鹰村委会土瓜地村苗族学员龙志福紧紧地拉着县农机安全监理站张站长的手不停地说。吆鹰村委会是云南省武定县狮山镇的一个典型山区村委会,山高、坡陡、沟深,少数民族众多,特别是苗族占到整个村民总人口的近三分之一,与插甸镇、高桥镇相邻,距离县城18公里。老百姓出行缺乏交通工具, 相似文献

A model to represent the discolouration of dried powder of carrots as a function of temperature was developed. Two types of carrots, Asian and European, containing large amount of lycopene and β-carotene, respectively, were tested. The dried powder was stored under an atmosphere with O2and at three different temperatures, 5,20 and 35°C. The surface colour of the powder was monitored during storage by a Hunter colour ratioa/b. In the proposed model, the rate of oxidation was assumed to be represented by the product of the fraction of concentration of oxidized pigment at arbitrary time and a specific rate of oxidation of pigment. The rate parameters in the proposed model were calculated by fitting the experimental data with smooth curves by trial and error at the end of the induction period but before discolouration took place. The frequency constant and activation energy, expressing the temperature dependence of the rate parameters, were expressed by the Arrhenius relation. The simulation results of a Hunter colour ratioa/bof dried powder at 25°C showed good agreement with the experimental data, suggesting that the proposed model was effective for the prediction of discolouration of dried powder of both types of carrot. The use of the induction period in the manner described may enable the shelf life of dried powder to be predicted. 相似文献

The fractional outflow rate of water from the rumen, measured as the rate of disappearance of the chromium complex of ethylenediamine tetra-acetic acid, was related to a number of dietary factors. A multiple regression equation was derived which expressed fractional outflow rate as a function of the intakes of dry matter, ash, acid-detergent fibre and crude protein.The data analysed consisted of 243 observations for sheep on 59 diets, including forage, concentrate and mixed diets. The ranges covered by the data were: fractional outflow rate 0.7–3.6 day?1; dry matter intake 560–1400g/day; ash 4–30%, acid-detergent fibre 7–41%, crude protein 5–26 % of dry matter; there were no observations for sheep of less than 34 kg liveweight.The equation accounted for 56·3 % of the total variance. Between-sheep variance could not be calculated for the whole of the data but was undoubtedly substantial since, for a sixth of the data, it was known to account for 38 % of the total variance. 相似文献
