在二手车的交易管理过程中,汽车车辆使用状况的鉴定是一项十分重要的工作,这项工作的开展不仅决定了二手车是否可以流通,而且还能够为车辆后续的使用提供重要数据支持。为此,文章结合二手车市场发展实际情况就二手车车况鉴定问题进行探究。 相似文献

通过相关数据对中国的二手车市场进行分析,就我国二手车交易占比小,成交平均价格较低等问题展开探讨,发现目前我国民众对二手车了解甚少,二手车评估体系不健全,售后服务不完善,车辆历史档案空白等现象导致消费者更青睐新车。可以从加大汽车知识宣传,健全相关法律法规和评估体系,完善售后服务和建立历史档案等方法来激发二手车市场潜力。 相似文献

据有关部门统计2012年1-4月,北京市累计成交二手车20.63万辆,相比去年同期的60742辆增长了239.6%。与此同时,前4月全国二手车市场累计交易车辆149.02万辆,同比增长21。34%;交易额738.56亿元,比去年同期增长37.51%。从数据来看,似乎二手车交易的小高潮已经来临。 相似文献

根据中国汽车流通协会统计数据,从2004年开始,我国二手车交易连续三年增长速度高达30%。目前北京市场的二手车交易量已经越来越接近新车的交易量。虽然跟国外相比还有不小的差距,但是已经说明在大环境的影响下,人们对二手车的态度正逐渐从排斥转为接受。由于经济危机的影响,加上油价高位徘徊和燃油税即将开征,用车成本增加,人们自然的把目光转移到小排量汽车和二手车上。 相似文献

随着我国农村经济的快速发展,农村二手车的交易越来越频繁.在转让农用车辆时,有的当事人怕麻烦或者图省钱,不去有关部门办理过户手续,由此引发种种烦心事,甚至发生民事纠纷,常使车主后悔不及. 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
