用废电池锌片制备硫酸锌的实验改进

化学通报 2007年第9期70卷 715-717页

作者：王红云钟四姣长沙环境保护职业技术学院长沙410004

用废电池锌片制备硫酸锌的学生实验,因锌的酸溶解过程所需时间太长而影响实验教学质量。本文采取加热、加入稀CuSO4溶液"催化"并实施锌的"部分溶解"等措施较好地解决了这一问题。

By employing a model potential including the electron exchange energy, we extend the semiclassical closed orbit theory to study the multielectron atoms. Using special region-splitting consistent and iterative method, we figure out the closed orbits in the corresponding classical system and calculate the recurrence spectra of triplet helium atoms in parallel electric and magnetic fields at scaled energy ε=?0.03,n≈40,n=0. The core-scattering effects have been taken into account, which lead to more peaks in the spectra. It has also been confirmed by means of the direct comparison between the spectral portrait in such a plot and those of hydrogen case. In order to compare the theoretic results with experiment, we investigate the closed orbits and recurrence spectra of helium atoms for the similar exchange potential but applied only by single electric field at scaled energy ε=?2.7 case. The spectra are in good agreement with the experimental observation. We conclude that our model is correct and it is necessary to consider the exchange effect for determining the photoabsorption spectra of multielectron atoms in strong external fields.

OBJECTIVE: To investigate the expression of cluster of differentiation 44 variant 6 (CD(44V6)) and proliferating cell nuclear antigen (PCNA) in ocular squamous cell carcinomas. METHODS: Streptavidin-biotin complex (SABC) immunohistochemistry was used to explore the expression of CD(44V6) and PCNA in 35 cases of ocular squamous cell carcinomas, 20 cases of papillomas, and 11 cases of normal eyelid tissue. RESULTS: The CD(44V6) positive rate was 62.9% (22/35) in ocular squamous cell carcinomas, 15.0% (3/20) in papillomas, but not detectable in the 11 cases of normal eyelid tissue. The positive expression rates of CD(44V6) in ocular squamous cell carcinomas were significantly higher than in benign tumors (chi(2) = 11.57, P
