Discrepant Measurements of the Radial Velocities of SS Cygni: Solution to the Problemby (1) poor choices of lines for measuring its velocity and (2) large distortions in its velocity caused by heating from the white dwarf and its accretion disk. The correct . velocity of the center of mass of the K5 V star is 158 ± 3 ...让你明白 发表于 2025-3-25 13:34:15
Epilogue,ong the issues yet to be fully understood is the similarity of isotopic composition of the Moon and the Earth. Solutions have been proposed, and most of them involve variations of the giant impact model, e.g., an impact between a large planetary body and an already fast-spinning proto-Earth.

,Geometrie auf einer Fläche,Bogenlängen aller auf der Fläche gezogenen Kurven bei der Verbiegung ungeändert bleiben. Etwas allgemeiner bezeichnet man als . oder . zweier Flächen aufeinander eine Transformation mit Erhaltung der Längen. Verbiegungen von Flächenstreifen haben wir ja schon im § 37 behandelt. Jetzt wollen wir uns mit der Verbiegung ganzer Flächen beschäftigen.细菌等 发表于 2025-3-26 16:38:21
Solving Satellite Range Scheduling Problem with Learning-Based Artificial Bee Colony Algorithmugh the experience of scheduling tasks guide the generation process of new bees. Experiments and algorithm analysis show that the learning strategy we proposed is of great help to planning tasks, and the performance of the new algorithm is better than state-of-the-art algorithms.揭穿真相 发表于 2025-3-26 17:38:20
