摘　　要：研究了一种线聚焦型太阳能二氧化碳发生器。分别在跟踪及非跟踪工况下,在呼和浩特地区测试并分析了系统的集热与产气性能。确定了系统的最佳运行方式,提出了气损率和产气能力2个系统性能评价指标。测试结果表明,跟踪较非跟踪工况,反应器内腔空晒最高温度、闷晒最高水温、最高集热效率分别提升16.30%、12.44%、94.50%;系统最佳运行工况确定为跟踪式。在产气原料分解温度范围内,系统集热效率为31.80%;测试阶段系统气损率为4.50%;当太阳直接辐照度在650～850W/m~2范围内变化时,系统产气能力随太阳直接辐照度呈正相关变化。基于系统产气能力的变化规律,可计算不同规模线聚焦型太阳能二氧化碳发生器的具体结构参数。As the core equipment of agricultural machinery, the tractors are rapidly becoming of increasing importance to agriculture. The technical advance of tractor products reflects the degree of national agricultural mechanization and the level of agricultural modernization. In recent years, novel structures and devices have been emerging on tractors, of which the technical level is constantly improved, and the overall performance keeps enhancing with the extensive application of various new technologies. Based on the analysis of the tractor development world-widely, the urgency and necessity of tractors to achieve automation, intelligentization and informatization were proposed. The latest researches on agricultural tractors in engine emission controlling, new energy altering, power shifting, continuously variable driving, front axle suspending, cab comforting, hitch electrohydraulic controlling, bus networking and system informatization were summarized. Meanwhile, the basic principles and characteristics of related technologies of each system were expounded combining with the application of specific products. Considering the national situation, the development direction of tractor technology was prospected with a historical and in-depth review of its development process. The precision agricultural system, which integrated high efficiency, energy saving, environmental protection and intelligence, benefiting from the rapid developing technologies of cloud computing, big data and internet of things, was thought to be a new model of future agriculture. Accordingly, intelligent perception and decision, efficient driving and remote controlling of intelligent tractors, which played an important role in the precision agriculture, were speculated to be the new bright spot and direction of tractor technology development in the future.
