Shuhua shuibaizhi (Myricaria laxiflora), an endemic riparian plant in the Three Gorges Valley of the Yangtze River, is the only species in the genus Myricaria that grows in low-altitude regions along the Yangtze River. The other species of the genus are distributed in Tibet and neighboring regions.Over the past decades, scientists are puzzled at why the plant exists alone along the Yangtze while its cousins are suffering from the arid and frigid climate. And the researchers are anxious to know more about the plant because its natural habitat will be mostly plunged under water owing to the construction of the Three Gorges Dam.  相似文献

科学界有一句格言,“创造的秘诀在于求异”。异,就是与众不同,就是独树一帜。许多科学家和发明家都是属于“特异”一类的人。他们勇于发表异言,乐于坚持异见,善于运用异思。总之,他们的特征是标新立异。“异”是思想的解放,观念的更新。有人曾把“异想天开”贬斥为不切实际的胡思乱想,这是一种偏见。其实,没有“异想”,何来“天开”呢?异想,使我们摆脱了控制性观念的束缚,使我们超越了常规式思考的限制。有人也将“见异思迁”一词用来讽刺某些在事业上不安分守已的人,这也是不恰当的。须知,这个“异”正是创造本能的体现。山…  相似文献

自然辩证法作为马克思主义的科学哲学,从其产生以来,自然界是否存在客观辩证法问题一直是争议的核心。辩证法概念发展的一般哲学史含义同德国古典哲学的特殊转义是造成自然辩证法概念理解分歧的根本原因。因此在哲学史背景下对辩证法概念进行文本学考察,是判别自然辩证法概念真实含义及其合理性的最可靠依据,是深入进行自然辩证法研究的前提,是保持马克思主义哲学体系完整性研究的基础。  相似文献
