村落是实现乡村振兴的基本单元,而地形则是村落形成的基础。通过对相关文献的研读,发现村落选址具有低海拔、小坡度的特点;村落布局遵循平坦地区规划农田,较平坦地区建设房屋的规则;平坦地区的村落形态呈规则状,高差起伏较大地区呈不规则状;村落规模随着海拔、坡度、地形起伏度的增大而变小;平坦地区的民居强调中轴对称,正南正北,地势起伏处民居随地形灵活多变;地形对村落公共空间影响的研究集中在街巷上,平缓区街巷横平竖直,十字交叉,高低起伏区街巷结合地形,随着地形自由布局。深入挖掘地形因素对村落特征的影响,对新时代不同地形下
One of the biggest challenges in the biocompatibility of implantable metals is the prevention of the stress shielding effect,which is related to the coupling of
Nondestructive cryogenically thermal cycling has been a simple but effective treatment to enhance mechanical properties of glassy materials.However,how the structural heterogeneities on nanometer scales are affected by thermal cycling is still an issue.He
