参与互动该列车在国际上首次采用“长定子永磁直线同步牵引+永磁电磁混合悬浮”技术方案，具有能耗低、牵引效率高、设备更换维修方便等特点。通过对牵引和悬浮系统的优化升级，在模块化、轻量化、集成化等方面实现了一系列关键技术突破，与我国现在投入运营的中低速磁浮交通相比，悬浮功耗降低20%，牵引效率提高10%以上，综合技术性能达到国际先进水平。“一个可降解的塑料袋如果沾上油污，那就需要先用化学试剂清洗干净，再进入降解的流程，这个过程又要消耗多少成本？”他说。

张剑锋认为，“原来的家电多是机械式的，记忆功能较弱，智能产品出现后家电企业对芯片的需求越来越多。同时，众多家电厂商不愿意在核心技术上受制于人，这也是众多巨头愿意进入芯片领域的重要原因。”
