The design of intermittent-motion linkages using traditional methods is usually complicated. In this paper, (1) a new method for realizing intermittent motion, using linkages with a slight difference in length between links, is studied; (2) some new types of intermittent-motion linkages and their software for visual analysis and design are developed; and (3) influences of some design parameters on intermittent-motion characteristics are clarified. Results confirmed that the theory and the software are useful, making the synthesis of intermittent-motion linkages clear and easy.

我国海洋温差能资源量巨大,主要分布在广东省和南海海域,是区域能源结构优化以实现碳达峰、碳中和的有效支撑,也是未来我国南海、 21 世纪海上丝绸之路沿线诸多岛屿能源补给保障的重要途径;目前海洋温差能发电( OTEC)技术和装备尚处于实验阶段,兆瓦级试验电站建设成本巨大,整体技术成熟度不及商业级利用规模,亟待发展突破。本文总结了国内外 OTEC 及综合利用的发展模式、技术装备所面临的挑战,针对南海温差能资源开发困境、广东省液化天然气( LNG)冷能资源浪费等情况,提出了以 LNG 气化的低温海水替代深层海水进行温差能发电的新途径。建议以珠海 LNG 气化站为例,探索 LNG 冷能回收 – 温差能发电、低温冷海水综合利用示范基地的发展模式;通过初步概算示范基地的投资与收益,完成了相应模式的经济与技术可行性论证。相关发展模式建议、应用案例论证过程,可为我国温差能与低温海水资源综合利用提供技术借鉴和应用参考。

Design a small flow back-to-back two-stage centrifugal compressor in the aviation turbocharger, the compressor is compact structure, small axial length, light weighted. Stationary parts have a great influence on their overall performance decline. Therefore, the stationary part of the back-to-back two-stage centrifugal compressor should pay full attention to the diffuser, bend, return vane and volute design. Volute also impact downstream return vane, making the flow in circumferential direction is not uniformed, and several blade angle of attack is drastically changed in downstream of the volute with the airflow can not be rotated to required angle. Loading of high-pressure rotor blades change due to non-uniformed of flow in circumferential direction, which makes individual blade load distribution changed, and affected blade passage load decreased to reduce the capability of work, the tip low speed range increases.

A novel three-stage integrated biofilter (TSIBF) composed of acidophilic bacteria reaction segment (ABRS), fungal reaction segment (FRS) and heterotrophic bacteria reaction segment (HBRS) was constructed for the treatment of odors and volatile organic compounds (VOCs)from municipal solid waste (MSW) comprehensive treatment plants. The performance, counts of predominant microorganisms, and bioaerosol emissions of a full-scale TSIBF system were studied. High and stable removal efficiencies of hydrogen sulfide, ammonia and VOCs could be achieved with the TSIBF system, and the emissions of culturable heterotrophic bacteria, fungi and acidophilic sulfur bacteria were relatively low.
