帕邢-巴克效应的简单处理

在强磁场中的单电子（价电子）原子，忽略电子的自旋一轨道相互作用，电子的自旋、轨道矢量分别绕外磁场作拉摩尔旋进而使能级分裂，从而讨论原子光谱的分裂并推出光谱分裂后的频率公式。     

Excitation energy transfer mechanisms in allophycocyanin (I)

The mechanisms of excitation energy transfer within allophycocyanin monomer with the theory of generalized master equation (GME) and the technique of time-resobed fluorescence anisotropic spectroscopy are studied. In the case of known information of its structure and spectra, the theory applied is based on the assumption that the coupling interaction between two chromophores is fairly weak. The theory correctly predicts the experimentlly observed rate for excitation energy transfer in allophycocyanin monomer. Based on the results, the energy transfer mechanism can be described as Förster and these processes cannot take place from the high vibrational levels of donor to acceptor.

~(154)Sm,~(156,158)Gd,~(158)Dy核结构研究

本文利用IBA2理论,从SU(3)极限参数出发,通过对激发能及B(E2) 值的理论与实验的比较, 找到了~(154)Sm,~(156、158)Gd,~(158)Dy核的Hamiltonian最佳参数。参数说明:~(154)Sm含有较大的振动成分;~(156)Gd,~(158)Gd是二个典型的SU(3)核;而~(158)Dy含有少量U(5)和少量O(6)成分的类SU(3)核,计算结果表明:稀土变形核的最佳参数及有效电荷有系统的规律。通过F旋破缺,可以解释低激发态间的M1跃迁。

微量添加元素对Al-Zn-Mg合金时效动力学的影响

利用电阻法研究了单独或同时添加微量元素Mn、Cu和Zr等对Al-Zn-Mg合金时效动力学的影响,结果表明:Mn、Cu和Zr都不同程度地推迟了GP区的形成过程,即延迟GP区的形成速度。并且判定:Cu参加GP区的形核过程;Mn可能参加GP区的形核过程;而Zr不参加GP区的形核过程,但固溶处理时形成的含Zr微细析出物在时效时可能起GP区的核心作用。     

A comparison of the effects of the optical isomers of isoproterenol on energy metabolism in a mouse sarcoma

Summary Disturbance to energy production in the S180 sarcoma (CB) by optical isomers of isoproterenol was assessed from altered adenine nucleotide levels at 1 h. The L-isomer almost halved the ATP level and lowered the energy charge significantly; the D-isomer was inactive. Dependence of tumor injury on cytochrome P-450 activity appears unlikely.One of us (GRNJ) thanks the Department of Surgery, Medical School, Kings's College Hospital, London, England, for the provision of experimental facilities; the Institute of Biochemistry, German Cancer Research Centre, Heidelberg, FRG, for permitting the measurement of metabolites; the Cancer Research Campaign, London, UK, for a part-time grant; and Zyma GmbH, München, FRG, and the estate of the late Dr Lucie Polak for additional financial support.
