Structure and Photoluminescence of Nano-ZnO Films Grown on a Si （100） Substrate by Oxygen- and Argon-Plasma-Assisted Thermal Evaporation of Metallic Zn

Nano-ZnO thin films were prepared by oxygen- and argon-plasma-assisted thermal evaporation of metallic Zn at low temperature, followed by low-temperature annealing at 300℃ to 500℃ in oxygen ambient. X-ray diffraction patterns indicate that the nano-ZnO films have a polycrystalline hexagonal wurtzite structure. Raman scattering spectra demonstrate the existence of interface layers between Zn and ZnO. Upon annealing at 400℃ for i h, the interface mode disappears, and photoluminescence spectra show a very strong ultraviolet emission peak around 381 nm. The temperature-dependent PL spectra indicate that the UV band is due to free-exciton emission.     

复合亚纯函数的亏量与增长性

亚纯函数F(z)称为复合，如果F(z)能分解为F(z)=f(f(z))， （1） 其中f是亚纯，g是整函数且f，g均非线性函数（当f是有理函数时，g可以是亚纯函数）。采用Nevanlinna理论的标准记号和结果，并引进记号△(a(z)，f)=1-limijf r→∞N(r，a(z)，f)/T（r，f）， （2）     

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。
