However, there is a world of difference between the inclusions in imitation jewels and those in natural stones.

By theoretical analysis and test research,this paper introduces the effect of tiny-hole laser machining parameters,such as energy of the laser pulse,width of the laser pulse,and repetition frequency of the laser pulse on the diameter and depth of the tiny hole for synthetic corundum material.

The current situation, existing questions and developing tendency of wood-based panel machinery in China;

Research about the amonium-vacuum method on the control of fomaldehyde emission from wood-based panel;

Study on surface performance of wood-based panel for furniture;

The authors reviewed the development of standardization for wood-based panels in China and analyzed the main problems existed.

It analyzes the change in world's production and trade of wood-based panels separately from changes in the volume, structure and the regional distribution, which is based on FAOSTAT statistical data of wood-based panels from 1961 to 2004.

Affects of new ideas for the birth and development of wood-based panels were reviewed, and its future was also looked forward.

The Dianix disperse dyes series were applied to dye imitative suede cloth, the exhaustion rate curves of traditional dyeing process and infrared dyeing process were compared.
