The power of theseapproaches is now more fully appreciated and well accepted, and they arebecoming the prevailing paradigm in the design and optimization of emergingthermoelectric materials. We also discuss the challenges to further advance thesenew insights to realize continued further improvements in ZT. Previous reviewarticles have covered nanostucturing,1–3,7–10 microstructurerelated to the thermoelectric properties,36 fundamental physicalphenomena,4 electronic structureengineering,37,38 nano-polycrystallinecomposites,6,9 or have focused onspecific materials such as clathrates,39 zintl phase compounds,40 oxides,41 organic materials42 and others.43–45 This article,however, discusses and highlights the significance of theall-scale panoscopicapproach to thermoelectric science and its application in achievingbreakthrough ZT in bulk materials.

With the development of society and economy, manufacturing enterprises have to play a decisive role position in the US, and the garment manufacturing industry has developed rapidly, but with the rapid development of enterprises, problems also occur.Now the enterprise rapid development today, the enterprise procurement cost also has changed from the traditional cost management to a strategic procurement cost management.Strategic procurement management focus on the enterprise total cost of purchase, there are fundamental differences with the traditional procurement cost management requires a minimum price of purchase.Requirements of strategic procurement cost management is supply chain procurement costs throughout the minimum, and can do the whole, multi angle of the monitor and management of supply chain, in this way, the enterprise can establish and maintain long-term competitive advantage.The garment manufacturing industry is labor-intensive industry, competition is fierce and the added value is low, the purchasing cost accounts for more than sixty percent of the cost of a product.And the relationship between business inventory procurement plan, procurement plan can make good control inventory cost enterprises better, so as to reduce the production cost of enterprises, improve the competitiveness of enterprises in the peer.So, clothing manufacturing enterprises procurement activities can better adapt to the production plan, accelerating procurement speed and reduce the total……余下全文
