Effect of Water Volume on the Growth of Silver Nanoparticles Promoted by Ultraviolet Jing Chena and Yeling Jin College of Bioengineering and Chemical Engineering, Jiangsu Provincial Key Laboratory of Palygorskite Science and Applied Technology, Huaiyin Institute of Technology, Huaian 223003, P.
Moreover, experiments reveal that high water volume results in the change of the color of the silver sol accordingly. 1 Introduction The study on metal nanoparticles is a hot research area in nanoscale science and engineering because of their unusual catalytic, chemical and optical properties resulted form their quantum size effect and surface effect [1-5].
Here, we report the effect of water volume on the growth of silver nanospheres, which is very important for understanding the growing mechanism of metal nanoparticles and helping the improvement of the synthesis accordingly. 2 Experimental Material and Apparatus Silver nitrate, citrate sodium and the other reagents were all analytically pure and used without further purification.

Introduction As is known, the determination of concrete stress-strain full process curve has important significance for establishing concrete constitutive relation and finite element calculation in engineering [1-5].
The condition of realizing concrete uniaxial compression The concrete is brittle material, when the compressive resistance test is carried out on common tester over the maximum stress (concrete compressive resistance strength), the specimen bursts crack immediately, and the stress-strain falling branch curve dose not have its own law.

Among them, the sound source control is one of the most fundamental and most effective method, the main sound source localization and recognition are the key issues in noise control engineering [1].
The technology of the sound pressure and sound intensity combination to identify environmental noise source can accurately identify the produce noise at boundary of the main sound source, which can be targeted to noise reduction of noise source, avoid troubleshooting each noise source noise reduction, which can save a lot of manpower, material and financial resources and has great application prospect.
