Empirically standardised peak luminosity of Type Ia supernovae(SNe Ia)as a standard candle has become one of the most powerful probes of the expansion history of the late *** the existence of such a consistent peak luminosity could be interpreted as a consequence of the fixed critical Chandrasekhar mass at which a carbon-oxygen white dwarf explodes,there is growing evidence for a more complex environmental dependence to the SN Ia luminosity beyond the current understanding of the SN Ia physics.

Frontiers of Law in China-Selected Publications from Chinese Universities 2024年第2期19卷 191-202页

作者： LIU yanhong Criminal Justice College China University of Political Science and LawBeijing 100088China

The traditional legal education model based on the discipline system of “theoretical law + departmental law” overemphasizes professional subdivision, resulting not only in the separation of different disciplines from each other, but also in the narrow thinking mode, single knowledge structure, and weak practical ability of trained legal talent, who are therefore hardly adapted to the needs of the era, which are characterized as cross boundary social problems and comprehensive knowledge application. All in all, the training of high-quality interdisciplinary legal talents lags behind social reform and the practice of the rule of law. In the context of comprehensively promoting the development of the new liberal arts, developing the new liberal arts, i.e., deep cross-integration, has penetrated into the construction of the law discipline, broken through the inherent limitations of law knowledge, promoted the interdisciplinary development of law education, and helped cultivate the ability of law students to integrate interdisciplinary knowledge. The development of new law science should proceed step by step, from shallow to deep. It should follow the guidance of social needs, break down discipline barriers, innovate cross-integration mechanisms, transform and upgrade from the “small crossover” among various departmental laws within the law discipline to the “big crossover” between the law discipline and other disciplines, and transform from the innovation of research methods to the innovation of the structure of disciplines. The cultivation of inter disciplines should focus on emerging fields such as national security, artificial intelligence, and social governance.
