摘要：Biocompatible designed micromotor has attracted more and more concerns in the field of biomedicine due to their self-propulsion and delivery *** micromotors,mostly consisting of alkali earth metals,hydrogels,or other motile biomaterials,can effectively transform chemical energy into mechanical or kinetic energy to achieve the expected delivery of cargos to the sites of *** for conveying power,the modifiable surface and inner cavity of micromotors guarantee that their potential as versatile delivery systems for therapeutic ***,this review generalizes the propelling mechanisms,composites,and shapes of ***,the application of micromotor-derived composites for biomedicine delivery and other versatile purposes are also discussed.

摘要：20世纪90年代末及21世纪初,千年一遇的旱灾使澳大利亚经历了有史以来最恶劣的干旱时期。悉尼不得不远程调水以维持当地供水,这样的情况一直持续到2012年旱灾正式结束。悉尼市已批准并将在未来实施＂分散水资源管理总体规划（2012—2030）＂,该规划将作为＂2030悉尼可持续发展计划＂的一部分。规划重点在于通过一系列措施减少自来水的消耗和需求,措施包括雨水花园、
