1958 年的"大跃进",使全国各行各业都进入一种"急功近利"的状态,高等教育于极短的时间里,在各地建设了一大批"高等学府",招生制度也向"左"转,只求数量,不管质量。这样做的结果,必然导致正常教育秩序紊乱,教育质量下降。"左"风盛行,为患多多。欲知详情,请阅《"大跃进"中的高校招生》一文。 相似文献

本文首先分析了新见到的3件铜器:黼鼎、26年佣叔壶与28年肮簋,论证它们都是穆王时期的铜器。并以此为基点,讨论了两件年代有争议的铜器:24年枷簋和30年吴盔,推定这两件铜器也是穆王时期的铜器,而且是标准器。然后将这几件标准器与以往所知的穆王时期标;住器联系在一起,其得穆王标;住器13件。据此第一次提出一个王世有“标;住器群”的概念,认为这将有助于进一步完善西周铜器断代研究的理论与方法,对重新认识穆王时期铜器的面貌,对于西周册命制度的研究,对于西周全文历谱的研究,也均具有重要意义。 相似文献

At 9 am, May 17th, 2013, we set out through heavy snow from the County of Honvuan forthe Xiaman Goat Husbandry Farm in Western Ruoergai. Along the way, we saw few humans but there were groups of yaks grazing with a quiet, masterful air on the snowcovered prairie. The road was uneven and our young driver, Tashi, seemed to like playing "dodgem cars" in this playground while trying his best to avoid every puddle along the way. Our SUVjolted up and down, splashing muddy water on the still falling white snow. In Secretary Norbu's car, and warmed by the heater, we arrived at tfhe Goat Husbandry Farm at ten thirty. Due to a power cut, that big farmyard was deserted but Tashi heated instant noodles for his breakfast in a pressure cooker on a wood stove. We were about 3500 meters above sea level so water boiled at only 80 degrees Centigrade. Half an hour later, a man rushed into the room, bringing the cold air with him from the outside wind and snow. He immediately extended his hand to us. "Welcome You are from the Southwest University for Nationalities Last year, President Wang helped us with monitoring and earmarking. We appreciated it very much." The "President Wang" just mentioned by Secretary Song Dingbin of the Xiaman Goat Husbandry Farm, was Wang Yong, Vice President of the Southwest University for Nationalities and Director of the Institute for Qinghai Tibet Plateau. He is tutor for the graduate students majoring in "Animal Genetic Breeding andPropagation", an expert who has made outstanding contributions in Sichuan. Privately, people would call him "Goat Wang". Jianzhou Big Ear Goat Actually, the name "Goat Wang" is not unique to Wang Yong. There is another "Goat Wang" in the school,Prof Wang Jie. Both "Wangs" study goats with considerable achievements, so both are given this excellent name. The difference is their respective ages. Professor Wang Jie has retired, so it is natural that Wang Yong is "Junior Goat Wang". For quite some time, our country has imported breeding goats from overseas. Secretary Song Dingbin said that in 1958 the state purchased some Merino sheep from Australia and New Zealand with gold, and established the Xiaman Goat Breeding Farm to produce high quality wool. As for meat production, the Boer goat has long dominated the market. Wang Yong, a Doctor in"Animal Genetic Breeding and Propagation", determined to change it. In 1998, supported by the Jianyang government, Doctor Wang Yong and his research team started to breed and cultivate the new "Jianzhou Big Ear Goat". They used the foreign Nubian goat to crossbreed with the local Jianyang goat. So a new population was produced and improved by crossbreeding and selection for the next generation by way of open herd breeding. The team employed a strict and complicated standard to select breeding goats. If any detail, no matter if it was appearance, 相似文献

<正>企业档案是企业在各项活动中形成的,企业活动是指企业生产、经营、行政、科研、基建、设备管理等各种职能部门,企业档案工作是企业研发、生产、经营、管理活动的基础性管理工作,应以满足企业各项活动在证据、责任和信息等方面的需求为导向,实现企业基本目标的活动。因此,企业档案是企业各种因素相互作用的产物,是各种内容和载体档案的总和。如何做好企业档案管理工作,我认为应该以下几个问题: 相似文献
