By 2008, Liu Jing-quan et al.[4] from Shanghai Jiaotong University had presented a generator array with Cantilever piezoelectric materials, which was able to control the frequency bandwidth to improve conversion efficiency and to generate a power of 3.98 μW as well as a direct voltage of 3.93V.
During 2007 and 2008, a micro-vibration generator with magnetostrictive materials (Metglas 2605SC) had been proposed by Wang and Yuan[4,5] to be used in harvesting energy for wireless sensor networks, which provided an electric power of 576μW, appearing far higher than one with piezoelectric materials on the same conditions.

Introduction Porous solid materials have created extensive research activity because of low working pressure, light weight and changeable form in hydrogen storage.
Subsequently, Long et al. [2] explored a new type of microporous metal coordination materials (MMOMs) with pore dimension comparable to length scale of the molecular diameter (0.289nm) of hydrogen.
The first two samples, sepiolite and palygorskite, had obvious hydrogen uptake platforms: the first may indicate the hydrogen adsorbing on the outer surface area of materials up to saturation, while the second shows that hydrogen may enter into channels and achieve saturation.

Then trim dry timber material as the size of groove and splice it in the groove.When the Surrounding wood of beam or column all need to trim,it must add 2 or 3 iron hoops to remain stable
(5) FRP reinforcement.Take FRP materials to reinforce timberwork frame.The common materials such as GFRP,CFRP and BFRP have the advantages of light weight, high strength, corrosion resistance, easy cutting, save artificial.FRP materials not olny improve beam’s and column’s carrying capacity, stiffness and ductility but also enhance its durability.
Conclusions Due to its special structure and excellent properties of materials, timberwork building is endowed with excellent seismic capability.But long neglected and in disrepair make the aseismatic function of these buildings recede seriously.In order to protect historical buildings and ensure people's life and property safety,we need analyse the causes of damage and provide the objective of earthquake-resistance to provide basis and method in timberwork building reinforcement.

Effect of Bell-type Annealing Process on Properties of SPCC Cold-rolled Steel Sheet Zhihua WANG 1,2,a ,Yanping ZHAO 1,2,b ,Yuntao LI1,3 , Jun WANG4 , Jian ZHANG 1,2 1 School of Materials Science & Engineering, Tianjin University of Technology, Tianjin 300384, China 2 Key Laboratory of Display Materials & Photoelectric Devices (Tianjin University of Technology), Ministry of Education, Tianjin 300384, China 3 Tianjin Key Lab for Photoelectric Materials & Devices, Tianjin 300384, China 4 The State Key Lab for Rolling Technology and Automation of Northeast University, Shenyang 110004.
Experimental method Experimental material is SPCC cold-rolled sheet specimen with thickness of 0.5mm.
In addition, it also can be observed: As the annealing time increasing, the yield strength of this material decreased; but the change of the strain is more complex: when annealed for 3h, its strain value can reach the maximum, which is 47%, while the strain is relatively small for 1h and 5h.
