T2铜的低温比热

在1.4—27K的温区内测量了纯度为99.9％的国产T_2铜的比热,得出了T_2铜的电子比热系数γ为0.68mJ·mol_(-1)·K_(-2),德拜温度θ_D为339.7K。与国外的比热数据比较,显然在纯度相同的条件下,比热数据是一致的,且可以互换。     

新型二硫纶·菲咯啉-5，6-二酮合铜(Ⅱ)配合物的磁性研究

报道了新合成的二氰基二硫纶·菲咯啉-5，6-二酮合铜(Ⅱ)配合物CuLL′(L=mnt^2-, 1,2-dicyano-1,2-ethylenedithiolate; L′=phen-5，6-dione, 1,10-phenanthroline-5,6-dione)的变温磁化率和电子顺磁共振波谱表征结果. 发现微晶粉体型的标题配合物CuLL′具有一定的顺磁性，形成四配位的近似于方形的结构. 探讨了这种配合物磁学特性与结构的关系.     

Crystal Structures of Two Potential Tumor Imaging Agents and Therapeutic Agents Copper（Ⅱ） Ternary Complexes with Salicylidene-tyrosinato Schiff Base and Nitrogen-donor Chelating Lewis Base

The crystal structures of two potential tumor imaging agents and therapeutic agents -copper(Ⅱ) complexes with salicylidene-tyrosinato Schiff base and nitrogen-donor chelating Lewis base, [Cu(sal-tyr)(bipy)] 1 and [Cu(sal-tyr)(phen)]2CH3OH 2 are presented. Our work is helpful to get deep understanding of novel 64Cu tumor imaging agents and therapeutic agents.     

GIANT MAGNETORESISTANCE EFFECTS IN Co／Cu （111） SUPERLATTICE

We present a spin-dependent scattering theory to explain the new type of magnetoresistance effect and magnetization in Co/Cu(111) su-perlattice with atomically smooth interfaces. Our model is simple, but the calculated results are consistent with the experimental ones.     

支气管灌洗液中铜锌含量及铜／锌比值的观察

用原子吸收光谱法检测了肺癌患者灌洗液中铜、锌含量及铜／锌比值。结果表明：中央型肺癌组与肺部良性疾病组比较均有极显著差异；与周围型比较，铜、铜／锌具有显著性差异；而周围型肺癌组与良性组比较，除铜／锌比值有显著性差异，Ｃｕ、Ｚｎ均无统计学意义差异。
