The performance of lean production practices improve productivity through reduced lead times, material and staff costs, increased quality etc.
Hence the selection of strategic partners that will furnish them with the necessary products, components, and materials in a timely and effective manner to help maintain a competitive advantage is challenge [12].

Growth of undoped GaAs single crystal by pulling-down method Min Jin1, a, Jiayue Xu1, Qingbo He2, Yongzheng Fang1, Hui Shen1, Zhanyong Wang1 and Guojian Jiang1 1School of Materials Science and Engineering, Shanghai Institute of Technology, Shanghai 200235, China 2Hangzhou Supercrystal Photonics Incorporation, Hangzhou, Zhejiang Province 311100, China ajmaish@yahoo.cn Keywords: Undoped GaAs; Pulling-down method; Crystal Growth.
As we’ve known, the physical properties of GaAs crystal were intimately sensitive to the purity of raw materials and the growth atmosphere.
When the raw materials were completely melted and successfully seeded, the pulling-down mechanism started to work and crystal growth was executed through the temperature gradient region.
GaAs crystal is a kind of soft materials and the origination of twins were reported as a crucial problem in industrial production [12].

Both of them belong to the sandstone cultural material, but their composition and character are different.
Because natural stone material isn’t uniformity texture, the surface is also coarse, so we cannot measure the tiny change of size by traditional tools such as vernier caliper.
The stones materials are porous, its chemistry and physics weathering effects become more obvious, at the high temperature and humidity in the box, because of capillarity and infiltration, plenty of water is absorbed, and the structure of jello is destroyed.
