Along with the science and industry development, structural vibration problems have become more complex and harm to people's lives and property security.
Its working principle like this: When the structure system is disturbed, relative motion happened between the piston and cylinder, the pressure differential on both ends of piston allows fluid viscous damper material through from damping hole to form damping foce, so as to achieve the purpose of energy dissipation.

Introduction Grain is both a foundation of national economic growth and an indispensible material basis of human survival and development.
In recent decade, there is continuous development in agriculture and perfection in industrial policy, meanwhile, the increasing yield and storage of grain in China thanks for the wide use of modern science and technology in agricultural production.

Experimental Materials and Methods.
Meanwhile compound 4 just came into being, and a majority of raw materials including DMT and NBS were consumed, while compounds 2 and 3 had only a moderate proportion of 14 % and of 9 % in the reaction mixture, respectively.
This indicated that raw materials reacted rapidly to almost entirely turn into 1 in such a short time, subsequently 1 reacted with NBS to transform into 2, 3 and 4.
Within less than 2 hours, more than 90 % of raw materials were exhausted, whereas it took 16 hours to put a termination to the alpha-bromination-reaction.

At these small sizes materials behave distinctively, giving QDs unprecedented tunability and enabling never before seen applications to photovoltaic technology [1].
All the materials in the field of view, including the quartz, epoxy, the deposited Ge-rich SiO layer and the n-type Si layer, are amorphous and with different color contrast.
However, the wave crest for quartz substrate is so wide from around 200 cm-1 to 500 cm-1 due to the characteristics of amorphous materials.
