加强高校预算管理

目前,高校预算管理存在着认识不全面、编制不完整、预算执行监督和管理不到位及与政府推行的财政体制改革不适应等问题.只有不断加强预算管理,积极探索,才能摸索出符合预算管理政策和财政体制改革,适应学校发展的预算管理模式.     

Electrochemical studies of glutathione monolayer assembled on a polycrystalline gold electrode

The glutathione (GSH) monolayer and complex monolayer of GSH-metallic ion on polycrystalline gold electrode were studied by using K₃Fe(CN)₆ as the redox probe. As for the GSH monolayer, it was found that the metallic ions could open the ion-gate in the monolayer dramatically in the order La³⁺> Pb²⁺>>Ba²⁺>Ca²⁺ whereas Zn²⁺ ion closed the ion-gate. The complexes of GSH-metallic ions were capable of self-assembling the different kind of monolayer. All the differences were related to the structural configuration of the anchored GSH molecule, which changed with different metallic ions or pH. Biography:Fang Cheng (1971-) male, Ph.

矛盾的根本属性与对外开放

矛盾根本属性原理是我们做好的对外开放工作的指导思想。在对外开放过程中，社会主义中国同国际资本主义双方的矛盾同一性是占据主导地位的，同时也必然存在着矛盾斗争性，但这是第二位的。我们应正确处理对外开放中矛盾同一性与斗争性的关系，着眼于矛盾双方的同一性，使必要的斗争性服务与服从于同一性，以利于对外开放基本国策的实施，加速中国社会主义现代化建设的进程。

邓小平对中美关系的论述及其现实意义

1977年邓小平复出后十分重视中美关系,在他亲自领导下,中美关系有了很大的发展,其间,也经历了许多波折。邓小平对中美关系的重要性有正确的判断,对存在的问题有清醒的认识,对中美关系的斗争性有充分的准备。回顾邓小平对中美关系的论述,在当前中美关系依然错综复杂的情况下,有助于我们正确把握中美关系的航向,有助于中美关系健康稳定发展。

The Frontier Movement and The American Values and Beliefs

This paper briefly accounts the background of American values and beliefs. It analyses the essence of the American ideals and points out that the American values are exaggerated and glamorized by the American upper class. They are in a sense, a dose of anaesthetic and a kind of hypocrisy.     

Studies on calcium‐containing poly(urethane ether)s

The calcium salt of mono(hydroxyethoxyethyl)phthalate [Ca(HEEP)₂] was synthesized by the reaction of diethylene glycol, phthalic anhydride, and calcium acetate. Calcium‐containing poly(urethane ether)s (PUEs) were synthesized by the reaction of hexamethylene diisocyanate (HMDI) or tolylene 2,4‐diisocyanate (TDI) with a mixture of Ca(HEEP)₂ and poly(ethylene glycol) (PEG₃₀₀ or PEG₄₀₀) with di‐n‐butyltin dilaurate as a catalyst. A series of calcium‐containing PUEs of different compositions were synthesized with Ca(HEEP)₂/PEG₃₀₀ (or PEG₄₀₀)/diisocyanate (HMDI or TDI) molar ratios of 2:2:4, 3:1:4, and 1:3:4 so that the coating properties of the PUEs could be studied. Blank PUEs without calcium‐containing ionic diols were also prepared by the reaction of PEG₃₀₀ or PEG₄₀₀ with HMDI or TDI. The PUEs were well characterized by Fourier transform infrared, ¹H and ¹³C NMR, solid‐state cross‐polarity/magic‐angle‐spinning ¹³C NMR, viscosity, solubility, and X‐ray diffraction studies. The thermal properties of the polymers were also studied with thermogravimetric analysis and differential scanning calorimetry. The PUEs were applied as top coats on acrylic‐coated leather, and their physicomechanical properties were also studied. The coating properties of PUEs, such as the tensile strength, elongation at break, tear strength, water vapor permeability, flexing endurance, cold crack resistance, abrasion resistance, color fastness, and adhesive strength, were better than the standard values. © 2003 Wiley Periodicals, Inc.
