The paper summarizes the studies on urban village (chengzhongcun) in domestic and abroad from four perspectives including the concepts and definitions,the formation mechanism,the value orientations,and the renovation and reform *** on the summary,the paper states that a neutralized value orientation should be the logical starting point of analysis on urban village;the formation of urban village should be interpreted within the framework of "institution-action;" and the strategy of community management of urban village should be made from the angle of constructing city low-grade community and the restrictions of current institutions and various practical conditions.

To explore a new structure form of fiber reinforced concrete, namely, the layered steel fiber and layered hybrid fiber reinforced concrete （LSFRC and LHFRC）, the mechanical properties of LSFRC and LHFRC, such as compressive strength, tensile strength, flexural strength, fatigue and durability were focused on. The experimental results show that LSFRC and LHFRC can improve the flexural strength of concrete by 20%-50%. In the aspect of improving the flexural strength of concrete, adulterant rate has more obvious effect than length/diameter ratio. Double logarithmic fatigue equation considered liveability was founded. The impermeability of LHFRC is superior to LSFRC and plain concrete （C）. However, the porosity of LHFRC is lower than LSFRC and C. The shrinkage of LHFRC at every age is obviously lower than C. The antifreeze durability of LHFRC is also better than C.

＜正＞Many footbridges may suffer from the intensive vibration induced by human activities, vibration serviceability have been more highlighted since more modern,slender footbridges are constructed in *** this paper,footbridge vibration evaluation criteria are suggested based on some of the design *** measurement is widely used to access the vibration serviceability of footbridge.A typical footbridge is taken as a real example to investigate the human-induced vibration through field *** the vibration characteristic of the footbridge is verified by finite-element *** dynamic responses of the footbridge under ambient excitations are collected through field measurement to identify the natural frequencies and mode shape of the footbridge by using Natural Excitation Technique（NexT） and Eigen system Realization Algorithm（ERA）.The vibration serviceability of the footbridge is checked based on dynamic responses made from field measurement and simulated result in line with the suggested footbridge vibration *** is seen that the first vertical natural frequency of the footbridge is in the sensitive frequency of human step *** the measured responses of the bridge are smaller than the permitted values in *** analytical results in this study can be taken as the references for the assessment of the pedestrian-induced vibration and dynamic serviceability of footbridges.

The results on theoretical and numerical modeling of resonant piezoelectric devices in China are reviewed. Solutions to dynamic problems of the propagation of bulk acoustic waves (BAW), surface acoustic waves (SAW), vibrations of finite bodies, and analyses of specific devices are discussed. Results from both the ultrasonics community and mechanics researchers are included. It is hoped that the paper will be useful for the understanding, communication and collaboration between Chinese and foreign scholars. The paper may also be helpful for bridging the gap between ultrasonics and mechanics researchers on piezoelectricity re- search. The paper contains 316 references.

针对武广客运专线沿线遇到的大量软质千枚状板岩,对作为路基填料的软质千枚状板岩的结构特征,包括颗粒组成和破碎特征进行室内实验研究,重点分析千枚状板岩的击实工程特性,包括击实特性、抗剪强度、回弹模量、CBR值、渗水特性、压缩特性等。通过实验研究得出千枚状板岩全风化体抗剪强度性能较好,用其填筑路堤边坡稳定。就回弹模量来说,千枚状板岩填料能满足路堤在刚度和强度方面的要求。采用风化软岩填筑路基时,当难以通过增大击实功来提高路基的填筑强度时,可通过增加粗颗粒的含量,实现路基强度的提高。本文同时也为用软质风化岩作路基填料的压实度控制问题提供依据。
