ABSTRACTThis study analyzes the Nobel Literature Prize award speeches from 2000 to 2023 from the perspective of polysystem studies and the framework of translational norms. Using a combination of corpus-based methods and qualitative coding analysis, it compares, describes, and interprets the discourse features and underlying norms of these speeches.

1. IntroductionTraditional radar detection systems [1,2,3,4] mainly rely on the relative motion of the radar and the target along the line of sight direction, that is, a linear Doppler frequency shift, to obtain the motion information of the target. However, because of how planar electromagnetic waves work, the line Doppler frequency shift of the target echo will disappear when the target’s motion is perpendicular to the direction of its propagation. This means that the target cannot be recognized.

Introduction Chilling temperatures (0–12 °C) inhibit plant growth and development, prolonged exposure to chilling temperatures of plant destroy cell membranes and lead to cell death (Degenkolbe et al., 2012; Ding and Yang, 2022; Kidokoro et al., 2022; Uemura et al., 1995). Thus, chilling stress is an environmental factor that has a significant impact on plant growth and productivity.
