The characteristics of high-confinement mode (H-mode) pedestal are examined on the Experimental Advanced Superconducting Tokamak. It is found that they are closely dependent on each other between electron pedestal characteristics and global parameters for all types of edge localized mode (ELM). The scaling of pedestal temperature based on thermal conduction and pedestal pressure width is carried out. Based on pedestal pressure gradient and pedestal density, six pedestal pressure width models are applied to predict the pedestal temperature height of type I ELMy H-mode. Compared to experimental results, the normalized poloidal beta model is more consistent than other models.

Miscanthus sacchariflorus is a typical perennial giant grass of East Asia as a biofuel feedstock. However, the mechanism of its salt tolerance is not well understood. In this study, chlorophyll a, b and total chlorophyll content, soluble protein content, MDA, proline content, POD, SOD, and CAT of M. sacchariflorus under salt stress were investigated with five NaCl concentrations ranging from 0 to 180 mmol.l-1. The results showed that the chlorophyll content decreased with increasing NaCl stresses, whereas soluble protein content, MDA, proline content, POD, SOD and CAT increased with increasing NaCl stresses. Low salt stress (30 and 60 mmol.l-1 NaCl) had almost no effect when comparing with the control under early stage (before 14 days) of salt stress treatment. However, treatment with high salt stress (90 and 180 mmol.l-1 NaCl) promoted MDA, proline, and antioxidant enzymes increasing markedly.
