In this paper,the statistical technique is employed to establish a model for the precision estimation of the gravity and deformation variation caused by barometric pressure loading calculated with Green's function method.Using the data of atmospheric pressure recorded in China and its adjacent areas,we obtain the error constants of the data and the estimation of precision of the atmospheric gravity and deformation signals.Our results agree with those of detection of the atmospheric gravity signals using tidal gravity observations with high precision in different weather condition.This method can be also used in other similar physical models.At first,based on the comprehensive analysis of the Green's function of the earth's response to air_pressure loads and the errors caused by the numerical calculation,a statistical technique is used to set up the error estimation model of the barometric pressure data and their noise at every individual station.And then,this model is generalized to the case for a plane.The model of observing errors,expressed with average air_pressure data,is obtained.The method of error estimation in Stokes formula,developed by Moritz,is employed to establish the model of error transformation caused by convolution.In consideration of the errors of air_pressure data,the model of error transformation and the statistical characteristics of barometric pressure data,we obtain the relationship of the Earth's response to the barometric pressure loads and the air_pressure signals,errors due to discretion and observing errors.Finally,in the calculation of the Earth's response to the barometric pressure loads,the effects of different kinds of errors on the final results are determined. The continuous air_pressure observations,with four samples a day,recorded at more than 700 stations,selected from over 2 000 ones,were employed in this study.The period of the observations spans January 1,1990 to December 31,1994.The covariance of the air_pressure variations between each two stations is analyzed,with the air_pressure variations as the random variables.The estimated values of the covariance (EVC) of the air_pressure variations between Wuhan and the adjacent stations were obtained.The surface distribution of EVC was derived based the station locations and their EVC.A transformation parameter Δ,defined in this paper,and obtained by numerical integration of the surface distribution function of the covariance and division by the autocovariance estimation at a given station,is about 10 6 km 2.We got the calculation deviations σ 1,reflecting the effects of the standard deviation of average atmospheric pressure upon the atmospheric gravity and deformation signals during sampling and unsampling periods,and σ 2,describing the effects of the atmospheric averaged signals standard deviation upon the atmospheric gravity and deformation signals.And then,the precision estimation of the calculation for the effects of barometric pressure upon the gravity and deformation is obtained. The results show that the precision of atmospheric correction to gravity is about ±0.103μGal for sampling period,and ±0.639μGal for unsampling period,respectively.Considering the fact that the observation precision of superconducting gravimeters is about ±0.2μGal,we can reach the conclusion that the former correction is effective,while the later one unreasonable.This agrees with the analysis of the Earth's tides in variant condition.

Similar material simulation is to study similar specific property between prototypal and imitable system through setting up similar physical model, and observing and studying the specific property of the system which can't be described in mathematics. The differentiation of model and prototype is only that there is a fixed proportion between the sequence structure and characteristic figure of the essential factors of the system, but the nature of controlling the system doesn't change. Setting up similar physical model is called similar physical emulated imitation from the point of emulation of the system.

The cable-stayed pipeline bridge is the typical long-span oil and gas transimission pipeline. Owing to its natural super-stationarity and high flexibility, compound dynamic load may be caused at the front and rear ends of the compensator by the fluid column in the pigging operation. Based on the similar physical model, the vibrating acceleration, displacement, tensile force of the cable will be confirmed by using the INV-306 intelligent signal gathering system.

The cable-stayed pipeline bridge is the typical long-span oil and gas transimission pipeline. Owing to its natural super-stationarity and high flexibility, compound dynamic load may be caused at the front and rear ends of the compensator by the fluid column in the pigging operation. Based on the similar physical model, the vibrating acceleration, displacement, tensile force of the cable will be confirmed by using the INV-306 intelligent signal gathering system. Therefore the original cable-stayed pipeline bridge canbe calculated. This is meaningful to understanding the dynamic response character of the pipeline bridge and avoiding the pipeline bridge's damage or failure caused by the dynamic load.
