ABSTRACT
Taking the construction project of the national weak magnetic reference laboratory of China Academy of Metrology as an example, the material selection and construction technology application in the construction of buildings, power distribution, and heating are systematically expounded. The technical problems of iron, cobalt, and nickel, or building materials with magnetic strength greater than 5nT (nanoteslas), which are not allowed to be used in the weak magnetic reference laboratory, are solved, and a feasible scheme for the construction of the weak magnetic reference laboratory is proposed.
