数据结构与图形技术

为了更好地理解和掌握链式存储结构、笔者尝试用图形和地址来表示数据结构中的物理存储结构及运算结果,收到了较好的效果.本文分析用图形和地址表示动态变量的分配问题.     

预制RC构件可靠度分析与验证荷载法

提出将预制ＲＣ构件在施工中所受的荷载视为验证荷载，用验证荷载法计算其可靠度的新方法。该方法既能提高构件的可靠度，又可避免对构件进行专门的验证荷载试验，计算结果更符合实际，而且经济、简便。     

吐哈盆地三叠纪孢粉地层学及古气候特征

吐哈盆地三叠系划分为韭菜园组、烧房沟组、克拉玛依组和黄山街组，通过对三叠纪地层的孢粉分析，建立了该盆地的四个孢粉组合带，Limatulasporites—Tae－niaesporites—Alisporites组合带、Aratrisporites—Punctatisporties组合带、Punc－tatisporites—Calamospora组合带和Cycadopites—Lophotriletes—Protoconiferus组合带。依据孢粉的演化得出吐哈盆地三叠纪的古气候为早期的干旱温暖到晚期的潮湿炎热。     

Study on the charge transference and local magnetic moment of yttrium-cobalt compound

The electronic charge transference and local magnetic moment of the YCo₅ intermetallic compound were calculated using SCF-MO-DVXα method and multiple cluster model. The result shows that about one 4d-electron is transferred from anY atom to Co₁(2c), and the calculated local spin magnetic moments of Co_I(2c) and Co_II(3g) atoms in YCo₅ compound are 1.33 and 1.48μ _B , respectively, which are in very good agreement with experiments.

Ab initio calculation of structure and Raman and Infrared spectra of Trifluoromethylthiosulphenyl Chloride

The molecular model of Trifluoromethylthiosulphenyl Chloride, CF₃SSCl, was presented.Ab initio method was used to calculate the structure and Raman and Infrared spectra. The results show that CF₃SSCl possess stereoscopic structure ofC ₁ symmetry with a torsional angle of 94.2°. The potential energy distribution and isotope replacement methods were applied to determine the vibrational assignment. The vibrational frequencies and corresponding modes of the molecule were obtained. The calculated vibrational frequencies are in good agreement with experiments.
