Our results show that many properties of the two models can be well reflected by the fidelity： （i） the mobility edge and metal-insulator transition can be characterized by the static fidelity; （ii） the extended state and localized state can be identified by the dynamic fidelity. Therefore, it may broaden the applied areas of the fidelity.展开更多

Therefore, the accurate translation of Chinese cuisines plays an important role in the spread of Chinese dietaryculture. Various dishes have their own evaluation standards and distinctive national characteristics. The translation of Chinese foodnames into English is an important part of the publicity work of Chinese food culture. Therefore, some translation problems of Chinese food are illustrated here with examples and several strategies are clarified for references.展开更多
