As a result of economic reform and opening up, annual industrial added value growth averaged 11.5% in 1978-2004, more than two percentage points higher than Gross Domestic Product (GDP) growth [19].With the rapid industrialization, the demand for natural resources and raw materials has risen rapidly.

Research on the Influence of Surface Sizing on Handmade Xuan Paper’s Modification Bai Weiguo1,2,a, Wang Lizhen2,b 1Jiangsu Provincial Key Laboratory of Pulp and Paper Science and Technology, Nanjing Forestry University, Nanjing, Jiangsu Province, 210037 2Department of Graphic Communication, College of Light Industry and Science and Engineering, Nanjing Forestry University, Nanjing, Jiangsu Province, 210037 aemail:ready73@vip.sina.com bemail: wanglizhen120@163.com Key words: Ink-jet Printing Xuan Paper Surface Sizing Abstract.
At present, most of domestic printing materials, such as “digital xuan paper”, are imported.
These kinds of the materials are based on the paper by machine not handmade.
Through surface sizing technology, the performance can be improved, and we can gain the following conclusions: (1).Through the appointed materials and the given technics, the handmade xuan paper’s part physical characters can be improved, mainly on absorbent, thereby improving reproduction performance such as density, dot gain, gamut, dots fidelity etc; [3] [4] (2).Analysis of all physical characters and reproduction performances, using the appointed materials and the given technics, the handmade xuan paper’s reproduction ability can be improved obviously when the rate of AKD and oxidized starch shows 1:2.

The large deformation at cryogenic temperature would be one of the effective methods to produce large bulk UFG materials.
Introduction Recently, ultrafine grained (UFG) materials with grain size less than 1-m have been studied extensively, since they are expected to provide high strength without the degradation of toughness.
Earlier works have shown that severe plastic deformation (SPD) techniques, such as equal channel angular pressing (ECAP), accumulative roll bonding (ARB), multiple compression and severe torsional straining (STS), etc. are effective in manufacturing UFG materials [1-5].
Among those processes, the large deformation at cryogenic temperature would be one of the effective methods to produce large bulk UFG materials.

Introduction In the past several years, SiO2 were widely introduced into polymers to improve the heat resistance, radiation resistance, and mechanical properties of polymer materials [1].
The elastomer shows better performance when the SiO2 content is around 1 wt%, and it keep balance after 1wt%, which was probably because of the physical adsorption and chemical link role between the interface of SiO2 and polyurethane elastomers. on the one hand, the interaction among the chains of elastomer was improved, which improve the tensile strength of the chain, on the other hand, the SiO2 particles in materials can bear the stress through these physical and chemical effects when subjected to the action of forces.
