The amount of spatial correction at each point can be derived from the average velocity and dip of the stratum at each corresponding point.

Vacuum Check Design of the Low Temperature Liquefied Petroleum Gas Tanks;

Static correction in mountainous area using space-time correction method;

Its vacuum calibration range is from 10~(-1) to 5×10~(-7) Pa, with an uncertainty of the standard for combined calibration up to 0.

Multi-sensor data fusion is one of the indispensably key technology of radar network,from the view of radar network project realizing,the text states the LU-Bang estimate method of single sensor toward target-track,and based on this fact states space-time adjusting question of multi-sensor data fusion,deduces calculation method of best fusion estimate.
