作者： Lezhi YE guangzhao YANG Desheng LI The 45th Research Institute of CETC Beijing 100176 China College of Mechanical Engineering and Applied Electronic Technology Beijing University of Technology Beijing 100124 China

An analytical model has been developed for analyzing the braking torque in electromagnetic retarder by flux tube and armature reaction method. The magnetic field distribution in air gap, the eddy current induced in the rotor and the braking torque are calculated by the developed model. Two-dimensional and three-dimensional finite element models for retarder have also been developed. Results from the analytical model are compared with those from finite element models. The validity of these three models is checked by the comparison of the theoretical predictions and the measurements from an experimental prototype. The influencing factors of braking torque have been studied.

Gigantspinosaurus sichuanensis is one of the six Stegosauria genera discovered from the Sichuan basin, which preserves the first skin impressions of stegosaurs around the world and a huge pair of ＇comma＇ -shaped parascapular spines kept in situ, and being named after the latter feature. The holotype was firstly named and reported in an abstract of a lecture by Ouyang, 1992, since when it has never been detailed studied and the taxonomic position of Gigantspinosaurus is also vague. The morphological redescription shows that G. sichuanensis is a medium-sized stegosaur, with external mandibular foramen developed. The ratio of femur to humerus is large, and the intersacral fenestrae are big. According to the wear degree of teeth, the holotype of G. sichuanensis is regarded as an adult individual. On the basis of the recent data matrix of stegosaurs and the characters revisions of G. sichuanensis, its phylogenetic position has been determined again. By our detailed morphological and phylogenetic analysis, G. sichuanensis is considered to inherit some primitive traits, but it is more derived than Huayangosaurus, and located in a transitional position between Huayangosaurus and Tuojiangosaurus, as a kind of evolved stegosaurs. The ancestors of Stegosauria are small and quadruped, with primitive ornithopod-like skull, and grow leaf-shaped teeth, a large number of bone plates.

The effect of pH on the conformation of surface alkyl groups and the structure of interfacial water molecules on poly[2-(dime-thylamino)ethyl methacrylate](PDEM) at the air/water interface were investigated with sum frequency generation vibrational spectroscopy(SFG-VS).At pH 4.1,the hydrogen bonding SFG spectra were similar to that of the air/pure water *** the pH increased from 5.4 to 9.6,the SFG intensities of both highly ordered hydrogen bonding(3200 cm-1 band) and less-ordered hydrogen bonding(3400 cm-1 band) were enhanced because of the charge-induced effect of deprotonated *** free OH peak disappeared completely because it was replaced by interfacial PDEM *** pH 11.5,a new spectral band appeared at about 3580 cm-1 in the ppp and sps spectra,and this could be assigned to the C2v asymmetric stretching mode of the water molecules through molecular symmetry *** hydrogen bonding structures are fully consistent with the conformational change of PDEM alkyl groups,and PDEM molecules act as a Hofmeister *** molecules are kosmotropic when they are charged and become more chaotropic as the pH increases.
