超重力场如何演绎“一眼万年”（院士讲科普）

Core Insights - The supergravity centrifuge simulation and experimental device (CHIEF) in Hangzhou, Zhejiang, has officially launched some core equipment, enabling unprecedented scientific experiments under extreme gravity conditions [2][3][4]. Group 1: Device Overview - The CHIEF device can simulate gravity conditions hundreds of times greater than Earth's, allowing researchers to explore material movement laws and geological evolution [3][4]. - The CHIEF1300 model preparation machine has a capacity of 1300 g·t, making it one of the world's leading devices in this field [4]. - The facility will eventually house three centrifuges, including the CHIEF1300, CHIEF1900, and CHIEF1500, arranged along a north-south axis in a 30,000 square meter experimental hall [4]. Group 2: Scientific Applications - The extreme conditions created by the CHIEF device can aid in research areas such as disaster prevention, deep-sea resource development, and new material fabrication [3][4]. - The device's capabilities allow for the simulation of long-term geological processes in a significantly shorter time frame, effectively compressing time and space for experimental purposes [7][8]. Group 3: Technological Innovations - The development of CHIEF involved a multidisciplinary team from Zhejiang University, integrating expertise from various fields to address complex engineering challenges [5][6]. - Innovative systems, such as a vacuum temperature control system, have been designed to manage the heat generated during high-speed operations, ensuring safe and stable functioning of the centrifuge [5][6]. Group 4: Experimental Capabilities - The facility includes 18 onboard devices, with 6 being internationally pioneering, enabling dynamic experiments under high centrifugal forces [7]. - Specific applications include studying the safe extraction of natural gas hydrates and simulating the impact of tsunamis on coastal engineering [7][8].
