| 1 | 高速船设计中舒适性的改善显示文摘要求高速船在公海航线上作长距离服务的呼声日益增长。因此,为了保证正常的乘客舒适性,降低居住舱室的振动和噪音,必须将波浪中航行的高速船的颠簸和加速度有效地控制在一定的范围内。为了满足这种要求,在这篇论文中,作者通过一系列水池试验的结果来阐明船体形状与适航性之间的关系,提出了一些减振降噪的措施,并建议把它们作为在初步设计中考虑乘客舒适性的启迪和对策。文章中,作者阐明了尖舭型船的底部斜升角对包括适航性和阻力性能在内的船舶总体性能的影响,并从适航性的角度将圆舭型船和尖舭型船作了比较,从中得出结论:船体形状可以在适航性与推进性能两者间作适当的权衡。作者还创新设计了一种新船型,它是在传统的尖舭型船的船首底部加上一个鱼雷形水下附体。当乘客舒适性要求较高的时候就可以用这种船型来取代旧船型。作者新近研究了一组带侧斜的五叶螺旋桨,而且还使用主机弹性支座和轻型阻尼材料来减缓船舶振动,降低噪音。这种轻型阻尼材料由两块铝板和中间弹性夹层组成。这些改进措施的效果都已在一艘大型高速客船的航行试验中得到肯定。最后,作者设计建造了一艘26米长的新型客船,安装了具有侧斜的五叶螺旋桨,船体壳板上敷设阻尼材料,其舒适性在航行试验和正常客运中都得到了证实。 | K.Kihara 朱慧琼 | 1989 | 江苏船舶1989，，1： | 0 |
| 2 | Cell-Based Biohybrid Sensor Device for Chemical Source Direction Estimation显示文摘This paper describes a method to estimate the direction from which the signal molecule reaches the sensor by using living cells.In this context,biohybrid sensors that utilize a sophisticated sensing system of cells can potentially offer high levels of chemicaldetection sensitivity and selectivity.However,biohybrid-sensor-based chemical-source-direction estimation has not received research attention because the cellular response to chemicals has not been examined in the context of directional information.In our approach,we fabricated a device that can limit the interface between the cell-laden hydrogel and the chemical solution of interest to enhance the time difference over which the chemical solution reaches the cells.Chemical detection by cells that express specific receptors is reflected as the fluorescence of the calcium indicator within the cells.Our device has eight chambers that each house 3D cell-laden collagen hydrogels facing circularly outward.The device also works as a cover to prevent chemicals from permeating the hydrogel from above.In our study,by observing the time course of the fluorescence emission of each chamber,we were able to successfully estimate the chemical-source direction within an error range of 7-13°.Our results suggest that a combination of microstructure devices embedded with living cells can be used to exploit cell functionalities to yield chemical-source directional information. | H.Oda K.Kihara Y.Morimoto S.Takeuchi | 2021 | Cyborg and Bionic Systems2021，，1： | 0 |
