摘要： This paper reports on the fabrication and demonstration of a novel autonomous centrifugal microfluidic dispenser that microchannels are patterned on the double side of the microchip. The dispenser executes metering of dispensing volume and injection into each target chamber. In a capillary dispenser that was previously reported is unstable, because liquids in the chambers during metering are kept by capillary force. However, the present double side patterning dispenser does not rely on capillary forces, owing to siphon valves, which three-dimensionally cross chambers and microchannels. In the experiments, it was confirmed that the double side patterning dispenser has a high accuracy of dispensing volume. Moreover, higher stability in repeatedly dispensing test was confirmed, in comparison with the capillary dispenser the. Therefore, it is expected to realize high stability and compact analytical systems, which are suitable for POCT, by integrating the dispenser on analytical devices. © 2020 The Institute of Electrical Engineers of Japan.

摘要： 现代教育应始终以立德树人为己任,完善立德树人的制度,并努力克服传统的桎梏,如唯分数、升学率等,以立德树人这种载体,来有效培养小学生的自主、自理管理能力相当重要,引导他们更好地自主管理。在人性化德育管理的模式下,有效引导、约束小学生,并全面落实客观评价制度,引导他们更好地自主管理,并凸显小学生的主体性,帮助他们不断提升积极创新的能力,以便能快速适应将来的社会。基于此,本文探讨了促进小学生提升管理意识措施及其相应的德育课程,以增强德育管理的“自律、自理、自主”模式,希望能推动基础教育的快速发展。
