The results show that there is perfect Linear correlation relation between gravityvalue and elevation under the conditions of areal small scale and perfect isostatic compensation.
通过分析，认为在区域性小比例尺及均衡补偿基本完善的条件下，重力值与高程有极好的线性相关关系；

In Xi 'an area, because the groundwater has excessively been exploited, the press-dense effect of strata appears so that the ground subsides and the gravityvalue increases sharply.
西安地区由于过量开采地下水，引起地层压密效应，造成地面急剧下沉与重力值急剧增加。

In January 2009, bilateral trade value dropped 21.6% year on year. The gravity and speed of the decline are unprecedented indeed.
