    摘要: A goniometer base for X-ray crystallography comprises a magnetic steel part with a cylindrical hole, a compliant cylindrical part that is inserted into this hole, and a cylindrical tube that is press-fit into the hole and holds the compliant part in place, such that when a crystal mounting tool is inserted through the concentric holes in each part, it is positively gripped and held in place at both T=300 K and T=100 K.
