Two-dimensional multiplicity fluctuation analysis of target residues in nuclear collisions

Multiplicity fluctuation of the target residues emitted in the interactions in a wide range of projectile energies from 500 A MeV to 60 A GeV is investigated in the framework of two-dimensional scaled factorial moment methodology.The evidence of non-statistical multiplicity fluctuation is found in 16 O-AgBr collisions at 60 A GeV,but not in 56 Fe-AgBr collisions at 500 A MeV,84 Kr-AgBr collisions at 1.7 A GeV,16 O-AgBr collisions at 3.7 A GeV and 197 Au-AgBr collisions at 10.7 A GeV.     

层次分析法在体育教学评估中的应用

全面正确地评估体育课的教学质量是体育教学管理的重要环节，也是当前教学改革中的迫切任务，目前的在方法多用单项指数，难以反映实际情况，通过引入美国芬兹堡大学运筹学教授Ｓａａｔｙ ＴＬ．创立的层次分析法，按照各项指标对体育教学质量影响程序的大小共相应的权重，并提出一种多重加权指数综合评估的方法。     

Azimuthal correlations of hadrons and fragments in nucleus-nucleus collisions

Two-particle (two-fragment) azimuthal correlation functions are studied by using a simple formula which describes uniformly azimuthal distributions of final-state charged particles and nuclear fragments. This formula is obtained in the framework of a multi-source thermal model (or multi-source ideal gas model). The calculated results are compared and found to be in agreement with the experimental data of charged hadrons and nuclear fragments in nucleus-nucleus collisions at intermediate and high energies.

有限自由度谐振子系统的力学问题

研究了有限自由度的谐振子系统，先给出了它的运动方程，并对其求解，又导出了它的运动方程的拉格朗日形式和哈密顿形式，将谐振子系统量子化后，由海森伯方程也可得出其运动方程。最后把经典力学和量子力学同时运用到谐振子系统的多种状态并且把它们推广到n维，从而验证了海森伯方程和哈密顿正则方程对谐振子系统的等价性。     

论广西地理环境与李纲旅桂心态

文学地理学方法为研究李纲的旅桂心态和旅桂诗特色提供了一个全新的角度。广西独特的自然地理环境和人文地理环境不仅以意象的形式出现在李纲的旅桂诗中,给李纲的贬谪诗歌带来了崭新的面貌,而且直接影响李纲旅桂心态的生成,构成其旅桂诗复杂的情感空间。
