Study on Factors Affecting Properties of Silica Liu Quanxiao*, Xu Wencai, Lv Yubin, Li Jinli Beijing Key Laboratory of Printing & Packaging Materials and Technology, Beijing Institute of Graphic Communication, Beijing, 102600, China *Corresponding Email: drllqx@163.com Keyword: silica, precipitation method, specific surface area, DBP absorption value, particle size.
Experiments 2.1 Raw materials Sodium silicate, Sulphuric acid, industrial grade. 2.2 Performance measurements 2.2.1 Performance measurement of silica Measure specific surface area and DBP absorption value of silica according to the national standard. 2.2.2 Particle size analysis of silica Analyze particle size with SA-CP3 CENTRIFUGAL PARTICLE SIZE ANALYZER made in Japan.
This is because the electrolyte in initial substrate material (Sodium silicate solution) and the concentration of silica can be partly regulating the performance of silica.

On the construction of live system, some subsystems such as camera control system,video signal PIP processing system,program material acquisition system etc are developed through continuous exploration.
The program material is collected in the FC RAID of the post producing system and can be called directly by the system during the post produce progress. 7.Application of multicenter picture separator Due to the space limitation of the guiding and control room, we use Miranda Kaleido 16 channel multipicture separator[7] to monitor all signals, such as three ways cameral signals, one way non-linear edit replay signal, one way pip video signal and pre-monitor signal of the control switcher.
The structure of kaleido multipicture separator 8.Summary The design and allocation of the hardware system such as cameral control system, video p-in-p processing system, program material uploading station, not only provide the government hotline live broadcasting with a stable effective working platform, but reduce equipment cost as well.

Introduction As a well-known brittle material, cement concrete has a lot of micro-cracks and uneven internal structures interior because of the raw materials, production process and other aspects, leading to the difficulty to improve the brittleness of concrete [1].
As a kind of high elastic materials, rubberhas high toughness, good performance of anti-fatigue and and permeability resistance.
Experimental Materials and Methods P·O42.5 cement was selected, coarse aggregate is 4.75-9.5mm single graded gravel and 9.5-26.5mm single graded gravel, two aggregate were mixed with the ratio of 6:4.
Because rubber powder can’t react with cementitious materials in the cement concrete, and does not belong to the hydrophilic material, so the adhesive ability of rubber power and cement paste interface is weak, which seriously affect the strength of concrete and causes much loss of strength.

The rare-earth (RE) doping of Si and Si-related materials [1-7] in the last years has been extensively studied for the development of light-emitting devices in the Si-based optoelectronics initiated by the reports on the photoluminescence (PL) and electroluminescence (EL) centered at around 1.54 μm of Er3+ (4I13/2→4I15/2) in Si [8].
The implantations of ions were performed on an ion implanter at the Institute of Semiconductors, Chinese Academy of Science.
