Due to their applications in magnetic, optical, electronic and catalyst, polynuclear lanthanide clusters are of importance. In this part, a series of nanowheel-shaped nonanuclear lanthanide clusters,〓〓(Ln=Sm~Tm; BA=benzoylacetone), were prepared and characterized. Each complex can exist in three phases, i. e., cubic, tetragonal and triclinic.

本论文第二部分在醇溶液中以三乙胺调变溶液pH，利用β-二酮配位方式的灵活性成功地构筑了一系列结构稳定、纳米尺度轮状的九核稀土配合物〓〓（Ln=Sm~Tm；BA=苯甲酰丙酮），并在不同溶剂中重结晶分别得到了三斜、四方以及立方三种晶型的晶体。

Taking the method of the indoor bioassay to study the herbicide antidote dichloro-N-acetyl-2-methyl-1-oxa-4-aza-Lo\nonane to reduce herbicide acetochlor on the stubble after the rice crop residues injury.

采用室内生物活性测定的方法，研究了除草剂解毒剂N-二氯乙酰基－2-甲基－1-氧杂－4-氮杂－螺[4.4]壬烷减轻除草剂乙草胺对后茬作物水稻的残留药害。

With the in-situ single-stage self-metallization protocol,surface-silvered polyimide film has been prepared using pyromellitic dianhydride/ 4,4\'-oxydianiline-based polyimide as the matrix and (1,1,1-trifluoro-2,4-pentadionato)silveras the silver precursor.

在原位一步自金属化法中，以均苯四甲酸酐/4，4\'-二胺基二苯醚基聚酰亚胺为基体，以三氟乙酰丙酮银作为银的母体制备出了表面金属化的聚酰亚胺银复合薄膜。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
