The invention provides a material management method and device. According to the material management method, the in-storage position of materials to be put into a storage and the out-storage position of materials to be delivered out of the storage can be known by scanning the materials to be put into the storage and the materials to be delivered out of the storage through a recognition technology; workers can directly put the materials into the storage and deliver the materials out of the storage through the in-storage position and the out-storage position; by scanning the materials to be put into the storage and the materials to be delivered out of the storage through the recognition technology, the number, in a data base, of the materials to be put into the storage and the number, in the data base, of the materials to be delivered out of the storage can be modified automatically. The shortcoming that the materials to be put into the storage and the materials to be delivered out of the ...

The invention discloses a neural network method for precisely determining tropospheric delays in a region; the neural network method comprises the following steps of: A1. obtaining an approximate true value of a tropospheric wet delay in a control point observation station; A2. establishing a tropospheric wet delay computation module in the region through the analogy computation of a neutral network; A3. computing a tropospheric dry delay in the region; A4. computing a tropospheric total delay in the region; and for other points in the region, obtaining delta 0, delta + and delta through respective computation according to formulas (5), (7) and (8) as long as four ground meteorological parameters (P0, T0, h0 and e0) are obtained through meteorological observation, then obtaining delta through computation according to a formula (9), and finally obtaining delta according to the formula (10). The invention puts forward a method for precisely determining a tropospheric delay modification ...
