High fusion triple product has been obtained in the advanced scenarios with high normalized beta (βN) on the Experimental Advanced Superconducting Tokamak (EAST).A record value of ni0Ti0τE ～ 1.0 × 1019 m-3 keV s for EAST deuterium plasma has been achieved,which is due to the formation of strong and broad internal transport barriers (ITBs) inne,Te and Ti profiles.Analysis shows that the strong ITB formation could be attributed to the reduction of transport from ITG modes.Based on the analysis,the physical mechanisms and methods to further improve the plasma performance are discussed.

研究普洗、雪花洗、酵素洗、漂洗4种常见化学洗水处理对不同材质、厚度、纹理的牛仔面料的影响。研究发现:当材质相同时,漂洗对牛仔面料经纬向断裂强力的影响最小,依次是雪花洗、普洗和酵素洗;当厚度相同时,漂洗对面料损伤最小、最结实,雪花洗后面料经纬向强力下降最大,最不耐用;当纹理相同时,漂洗影响最小,最结实,普洗影响最大,最不耐用。因此夏季在选择牛仔服装时,建议选择漂洗后的服装,这样既美观又耐磨。
