摘要：随着城市的发展,人类对地球上有限的空间和资源的争夺不断加剧,许多野生动物因此失去家园甚至失去生命。我们有必要在城市中引入更多植被及其所包含的微生物,以重建一个更多元的生态系统,并通过调节温度和CO_(2)等条件,增强城市环境的可持续性和韧性。生物可接受性设计是将生物多样性融入现有城市基础设施的一种解决方案,尤其适用于高密度城市环境和与自然界隔绝的室内环境。利用3D打印技术的高精度,我们可以设计出特定的复杂几何形状,起到促进生物生长的作用。

摘要：In this article,we report the principle and conceptual design of a fundamentally different technology infabricating high precision aberration free optical *** tip-tilt of facet in a mirror array is produced by digitallycontrolled line-tilts of rows and *** has not only provided a cost-effective designing methodology in opticalphysics but also led to a much finer precision of 1 mili arc sec or *** examples of the application of the proposeddigitalised optics,two case studies have been given:a 10 m Schmidt telescope(off-axis)and an 8 m Cassegrain telescope(on-axis).
