摘要: 论述了我国发展真空管道高速交通的必要性和可行性.就管道压强、遮挡系数及其关键技术等基本问题 展开讨论.重点论述我国发展真空管道高速交通的战略方针和技术方案.提出采用高温超导磁浮导向,同步线性 电机牵引和低压强管道所组成的系统.建议立即开始研究试验,以期能于2030年前实现600~1 000 km /h超高 速真空管道磁浮列车的商业运行.Abstract: The necessity and feasibility of evacuated tube high-speed transportation were discussed. The fundamental problems of this technology, e. g. pressure in the tube, coefficient of coverage and other related techniques, were analyzed in detai.l More discussed were the strategy and technical choice ofdeveloping this kind of transportation in China. The system consisted of partial pressure in tube, high-temperature super conducting magnetic levitation and synchronic linearmotor traction is proposed to be the variantofdeveloping research, so that the 600-1 000 km/h high-speed evacuated tube trainmightbe able to run commercially by 2030.
