Anta has launched a blockbuster new product, the Irving 1, and has fully entered the overseas market.Anta has been particularly cautious in choosing the right time to expand overseas. While Anta had previously ventured into Southeast Asia, Eastern Europe, and the Middle East, it remained primarily focused on the fiercely competitive domestic market. It wasn't until December 2021,when Anta Group announced its "New Ten-Year Strategy" and defined its goals as "single focus, multiple brands, and globalization," that it truly emphasized its strategic focus on globalization.展开更多

At 25 ℃, I=0.1 mol/L KNO 3, the stability constants of the binary system formed by the ligand with metal ions in ethanol aqueous solution were studied by pH potentiometric titration and the appropriate structures with respect to the titration species were proposed. The results show that the stability order of divalent metals binding to the ligand is Co<Ni>Cu<Zn which does not conform to the order of the Irving-Williams series. Then the abnormal property of copper complex is discussed.展开更多
