Abstract: The present application relates to a synthesis method for N-methyl-3-substituted methyl-4-pyrazolamide derivative and N-methyl-3-substituted methyl-4-pyrazolic acid, including the following steps: step S1: synthesis of intermediate E; step S2: synthesis of intermediate D; step S3: synthesis of intermediate C; step S4: synthesis of N-methyl-3-substituted methyl-4-pyrazolamide derivative; and synthesis of N-methyl-3- substituted methyl-4-pyrazolic acid by decomposition of N-methyl-3-substituted methyl-4-pyrazolamide derivative.

Abstract: Disclosed is an electromagnetic prediction method for concealed orebodies. A factor associated with an observation direction and a factor associated with a frequency are retrieved from tensor impedance data after static shift recognition and correction. An electromagnetic recognition factor including anisotropic characteristics is constructed. A probability of a developed orebody in a particular underground depth range of a target area is then inferred by using the electromagnetic recognition factor alone or as a component of comprehensive prediction information. Due to the full use of a potential correlation between anisotropic characteristics of frequency domain electromagnetic fields and an apparent metal factor and two-dimensional (or three-dimensional) extended concealed orebodies, the success rate of predicting spatial locations and attributes of the concealed orebodies is improved.
