新余高专2005级新生心理健康状况调查报告

采用临床症状自评量表（SCL-90），对新余高等专科学校05级新生进行了团体测试。结果显示：我校2005级新生与我校2004级新生相比，心理健康水平相对较低。但与2001年全省专科大学生心理健康调查数据相比，我校2005级新生心理健康水平相对较高。从总体看，男生心理健康水平优于女生。     

大学生口算能力的实验研究

为考察大学生的口算能力,我们随机选取30名大学生为被试进行口算的实验研究,主要结论如下:(1)大学生的口算速率在加、减、乘、除法之间存在差异,从快到慢依次为:除法,借位减法,不借位减法,不进位加法,进位加法,乘法;(2)口算的广度从大到小依次为:不进位的加法广度,进位加法广度,不借位减法广度,借位减法广度,除法广度,乘法广度;(3)大学生口算的速度和广度既无显著的专业差异,也无显著的性别差异.     

A Novel and Efficient Catalytic System for Aerobic Oxidative Coupling of 2-Naphthol Derivatives

The paper reported a novel and efficient aerobic oxidative coupling reaction of 2-naphthol derivatives catalyzed by CuCu (Ⅰ or Ⅱ)N-alkylimidazole complexes in excellent yields. The crystal structure of CuCu(Ⅱ)N-methylimidazole complex to be determined by X-Ray.     

Bis[μ‐1‐(1,10‐phenanthrolin‐2‐yl)‐2‐pyridone]bis{aqua[1‐(1,10‐phenanthrolin‐2‐yl)‐2‐pyridone]cadmium(II)} tetrakis(perchlorate)

In the title centrosymmetric binuclear complex, [Cd₂(C₁₇H₁₁N₃O)₄(H₂O)₂](ClO₄)₄, the Cd^II ion assumes a distorted octahedral geometry. There are π–π stacking interactions between the pyridine and 1,10‐phenanthroline ring systems of adjacent ligands at the same Cd^II centre. Intermolecular hydrogen bonds between the coordinated aqua ligand and the O atom of a keto group connect adjacent complex cations into extended chains. Hydrogen bonds also exist between the complex cations and the perchlorate anions. Compared with the fluorescence spectrum of the organic ligand, the complex displays strong fluorescent emission and an ipsochromic shift of the emission peaks, which may be attributed to the structural character.

Strong limit-point classification of singular Hamiltonian expressions

Strong limit-point criteria for singular Hamiltonian differential expressions with complex coefficients are obtained. The main results are extensions of the previous results due to Everitt, Giertz, and Weidmann for scalar differential expressions.

     

对英语专业八级口语口译考试评分的探讨

本文通过对英语专业八级口语口译考试的评分标准的考察，指出八级口语口译考试评分中两个突出的特点，即突出口语考试和口译考试评分“信息单元化”，从而影响口译质量评估的有效性。适当改变评分比例和口译评分标准的改进将有助于改善测评效果。     

Classical Limit of Expectation Values in a Wave Packet Involving Few Stationary States

Expectation values of physical quantities in a wave packet involving few stationary states in an infinite square well are calculated. Explicit results show that the expectation values in the classical limit go over to the corresponding classical quantity in the form of the arithmetic mean (in mathematical term, the Fejér's average) of the partial Fourier series converging to the classical quantity. The number of the stationary states is that of the partial Fourer series in the Fejér's average. The quantum uncertainty is then demonstrated to have a classical counterpart.     

音乐心理学在儿童音乐教育中的研究与应用

音乐心理是人脑的特殊机能,是大脑对客观音乐现实的主观反应.黑格尔曾说过:"音乐是进入更高的知识世界的唯一的、非物质的方法."说明了音乐心理学在音乐再教育中具有更科学的作用和更崇高的地位.
