On the morning of May 16th in the Village of Jarlama, in the Township Village of Achok in the County of Hongyuan, our interview team finally found Professor Tang Cheng and his team members. They are experts on veterinary medicine from the School of Life Sciences and Technology in theSouthwest University for Nationalities. Threes days before, Professor Tang Cheng received a call from the prairie to Chengdu Campus and was told that a group of yak calves had diarrhea. As soon as he put down the phone, Professor Tang began to organize his students, packed experimental equipment for them, and drove for the highland. Before we arrived at Hongyuan, they had been working on the plateau for two days. 相似文献

食货派的史学理论与方法具有自己的特色,具体表现如下:接近唯物史观,却不是唯物史观的社会史观;从探寻中国社会形态的演变到新经学的研究旨趣;重视史料但不忽视理论的治史主张;倡导分工合作的治史路径等。他们的史学思想对推动社会史论战之后学风的转变起了一定作用,在四十年代中后期也一度产生了积极影响。但抗战爆发以后,食货派未能从史学发展中去理解和把握学术研究的本质要求,没有对唯物史观认真总结,致使其史学思想黯然失色。 相似文献

在历代方志编纂中,民俗都受到了编者的重视,或设编或立目,详加记述。在新方志编纂中,民俗也同样受到了重视。原因在于民俗风情具有资治、教化的作用;民俗的传承演变反映着时代的变迁;民俗文化在当今社会具有重要的价值需求。但已出版志书在记述民俗方面存在着一些问题:内容或断线或缺项,有失民俗的历史性特征;沿袭旧志,缺乏新意,有失志书的时代性特征;记述欠准确,标题与内容不符,有失志书准确性特征。第二轮民俗志编纂需遵循的原则是:以科学发展观指导民俗志编纂;与时俱进,提高民俗记述的准确性;详略有致,准确揭示民俗传承、变异规律;充分运用现代科技手段,重视民俗摄影图片的运用。 相似文献
