和平精英冷门挑战大赏

随着“新质生产力”概念的提出，教育，特别是职业教育的重要性显得尤为突出。本文探讨了开放大学数学学科在促进新质生产力发展中面临的挑战，包括学生学习能力差异、个性化教学资源的不足以及教学质量监控实时性不足等，并就此提出了一系列应对策略，以期为开放教育的改革与发展提供理论依据与实践指导。

The LiAl is a typical intermetallic compound which has many important applications. We have employed the first-principles pseudopotentials and the plane wave energy band method to calculate the vacancy formation energies of Li and Al vacancies in LiAl intermetallic compound as well as the atomic relaxations around the vacancies. The charge redistribution around the vacancies, electronic densi ty of states and their band structures are also discussed.
