压缩时空 重现自然演变过程——探访超重力离心模拟与实验装置
Ke Ji Ri Bao· 2026-02-10 02:27
在杭州城西科创大走廊一座形似未来飞船的建筑内,国家重大科技基础设施——超重力离心模拟与实验 装置(CHIEF)建设迎来关键节点。 超重力,听起来虽显专业,但生活中无处不在。乘坐过山车时面部的拉扯感、飞机爬升时的压迫感、汽 车瞬间启动的"推背感"……这些都是我们熟悉的超重力体验。而CHIEF所要创造的,是百倍、千倍于地 球重力的极端环境。 "其核心在于改变力场强度。"CHIEF总工程师、浙江大学求是特聘教授凌道盛解释,"通过超重力带来 的缩尺、缩时和能量强化三大效应,我们得以在实验室里重现自然界中漫长、宏大乃至极端的过程。" 乘坐电梯深入地下,步入金属包裹的圆形实验大厅,CHIEF1300的钢铁身躯赫然展现。它舒展着6.4米 长的双臂,两端悬挂的8吨吊篮宛如"科学使命舱"。当它开始旋转,便能模拟出10g—300g(重力加速度 单位,1g≈9.80米/平方秒)的超重力环境,其综合性能指标达到1300g·t(重力加速度·吨),位居世界前 列。 "在吊篮中放置不同的实验舱,就相当于把高山大海、高楼大厦'搬进'实验室。"主机组组长、浙江大学 副教授汪玉冰生动地比喻道。这套系统使科学家能构建从原子尺度到千米尺度、从瞬间变 ...

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].
