    文章在简要介绍了关于创造力的各种理论和评述后,重点介绍了关于创造力的系统观点,强调创造力的表达或杰出成就的出现不应该被看成是个体的特征,而是个体和环境交互作用的结果,是一个需要在一定时间进程中由量变到质变的累积过程。同时,从个体的创造力、家庭对创造性人才发展的影响,以及社会文化等因素对人才发展的影响等方面,探讨了与杰出人才培养有关的问题。在教育教学中,从理念到课程、从形式到方法都应该学生为中心,真正开展因材施教,使教育教学适合儿童、青少年的心理发展水平和特点;在人才评价和使用机制上,应注重人才制度的建立和管理机制的完善;在建立和完善人才制度的同时,在全社会营造有利于创造力表达的文化氛围

    In a search for novel agrochemical with high activity and low toxicity, a series of substituted 4,5-dihydro-imidazol-5-one containing selenomorpholine group were synthesized by a three-step synthetic route starting from 2-azido-3-aryl-acrylic acid ethyl ester. The structures of title compounds were confirmed by H-1 NMR, IR, mass spectroscopy and elemental analysis. The preliminary bioassay against Gibberella zeae, Fusarium oxysporum, Pellicularia sasakii. Physalospora piricola and Cercospora beticola indicated that most title compounds displayed fungicidal activity at the concentration of 50 ppm and compounds 41, 4n, 4o were found to have particularly high activities against Physalospora piricola. A further in vivo test showed that compounds 41, 4n and 4o possessed better fungicidal activity against Physalospora piricola at a concentration of 100 ppm than Carbendazim. To our knowledge, this is first report that 4,5-dihydro-imidazol-5-one containing selenomorpholine group display fungicidal activity against Physalospora piricola
