简介：在过去的十年，nanopores为各种各样的潜在的应用程序广泛地被开发了，并且他们的性能极大地取决于nanopores的表面性质。原子层免职(ALD)是为扔薄电影的一种新技术，它很快从一种壁龛技术被开发了到一个确定的方法。ALD电影能保角地甚至在nanoscale在限制区域盖住表面，因此，是一个强大的工具修改合成nanopores并且也的表面制作复杂nanopores被证明。这评论在nanopore合成和ALD基本知识上给简短介绍，然后集中于由ALD和他们的应用程序处理的合成nanopores的各种各样的方面，包括单个分子的察觉到，nanofluidic设备，nanostructure制造和另外的应用程序。

简介：在3D抵抗力倒置最小化答案的数字，在倒置的一个固有的问题，考虑的数据的数量不得不大，优先的限制需要被使用。关于一个地质的异例的程度的地质、地球物理的数据是重要优先的信息。我们在3D建议形状限制的使用电的抵抗力倒置。三加权的直角的向量(正常和二正切向量)被用来在异例的边界控制抵抗力差别。异例的边界上的异例和限制的空间形状因此被建立。我们在3D抵抗力倒置的客观功能合并了空间形状限制并且与空间形状限制构造了3D抵抗力倒置方程。随后，我们使用了抑制方向向量和3D抵抗力倒置的重量的基于优先的空间形状数据的数字建模。我们建立了在方向向量和重量之间的一个合理范围，并且验证了使用空间形状的可行性和有效性在减少过多的结构和答案的数字的优先的限制。我们使用了优先的空间地抑制形状的倒置方法在广州地铁定位含水土层。空间形状限制从渗透雷达数据的地面被拿。含水土层的地点和形状的倒置结果与钻倒置的数据，和数字同意解决方案显著地被减少很好。
