Anisotropic structures, nanoneedles, and nanospindles of rare earth hydroxychlor.d. （rE（OH）2Cl） and oxychlor.d. （rEOCl）（rare earth=Eu and Tb） were synthesized. The rare earth hydroxychlor.d. nanostructures were formed via a thermally assisted hydrolysis of the rare-earth sesquioxide nanocrystals. The morphological evolution of the nanostructures was studied using high-resolution transmission electron microscopy and scanning electron microscopy, while the structural evolution was investigated using X-ray diffraction techniques. The thermal stability of the rare earth hydroxychlor.d.s was investigated using thermogravimetric analysis. The rare earth oxychlor.d. nanospindles were synthesized via a simple heat-treatment of rare earth hydroxychlor.d. nanospindles.

蛋鸡的遗传进展是否存在着极限

自本世纪初以来,蛋用型鸡的育种者一直致力于提高其鸡种的生产性能。通过综合改善疾病防制、营养、光照程序和其它非遗传性因子,也通过改进品系间和品系内的遗传选择,提高了每羽母鸡的平均产蛋量。由于遗传和非遗传的变化对产蛋量的影响可能是同向的也可能反向的,因此不可能根据逐年的变异来评价遗传进展。 dickerson(1955)分析了来自Krnber鸡场1931～1953年的测试数据,尽管进行了强度选择,但没有发现进展的迹象。那时,每羽圈存母鸡的年产蛋量看来有个接近200枚的极限。 Clayton(1968)
