University of Technology, Guangzhou 510640, China) Abstract: Weighting model is the only valuation model of life cycle impact assessment(LCIA) profile now. It simplifies evaluation function into linear function, and makes the determination of weighting factor complicated. Therefore the valuation of LCIA profile is the most critical and controversial step in life cycle assessment(LCA). Development......
) Abstract: The thermal stability of the eutectic Na2CO3-NaCl molten salt was investigated from the melting point to 1 000 ℃. The mass loss at high temperatures, the cycle performance, the component... the cycle times. XRD studies show that the composition of the molten salt is unchanged after high-temperature treatment is prolonged, and the relative contents of NaCl and Na2CO3 have no change......
