It can be expressed mathematically as the product of the density of the rock, the height relative to sea level or another reference, and a constant, in units of mGal: Strictly interpreted, the Bouguer correction is added to the known value of gravity at the reference station to predict the value of gravity at the measurement level.

严格说来，在参考点的已知重力值上加上布格校正可以预测在测量高度上的重力值。真实值和预测值之间的差是重力异常，重力异常是由测点下方的真实地球和参考模型之间的密度差异引起的。

In mountainous area, gravity survey external corrections, including terrain and Bouguer corrections, are the prerequisites for gravity data processing and interpretation.

In this paper, we put forward a 2.5D model based on the hexahedron and developed an inversion method of constraint gravity-vertical fault. The inversion result is better than that the 2D model through the model tests. Based on this model, we quantitatively interpreted the Bouguer gravity anomaly of the Sierra Nevada Region in the USA.

本文从六面体模型出发，将二度体模型修改为似二度体模型，建立了一个带约束的重力－垂直断层反演模型，经过理论模型试验，证明效果要优于二度体模型的反演结果，在此基础上对美国内华达州的圣安德烈斯地区的布格重力异常资料做了定量解释。

Terrain correction is needed when we do research on the internal structure of the Earth, the Lunar, and Mars by use of satellite gravity measurements, then calculate global Bouguer gravity anomalies. It is effective to carry out terrain correction in spherical coordinates.

利用卫星重力测量资料研究地球、月球与火星等星体的内部构造时，需要进行重力地形校正，计算全球布格重力异常，而在球坐标中实现地形校正计算是一种有效的途径。

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
