The most easily observed example of such gravity waves is that of waves in the lee of mountains . 最容易观测到的这种重力波是产生在山背冈的重力波。
By this electric repulsion and attraction he was able to counterbalance the influence of gravity . 通过这种电的排斥和吸引，他能够将重力的影响抵销。
Let us trace out in greater detail this computation of acceleration due to gravitational forces . 让我们详细追查这些由重力所引起的加速度的计算方法。
If the gyro tilts, the mercury is subjected to components of gravity which vary harmonically . 如果陀螺转子发生倾斜，水银受按简谐运动变化的重力分量的作用。
Such variations are in many ways similar to the large-scale regional anomalies observed in gravity work . 这种变化在许多方面与重力测量观察到的大范围区域异常接近。
The force of gravity is not constant everywhere for elliptical form and rugged surface of the earth . 由于地球的椭圆形状及其高低不平的表面，重力不是到处都一样的。
The work of the gravitational force, therefore, depends only on the initial and final elevations and not on the path . 所以，重力的功仅取决于初高度和末高度，而与路径无关。
It is often impossible to differentiate between structure and density contrast in determining the source of a gravity anomaly . 在确定重力异常源时，不可能在构造与密度差之间作出抉择。
The value of gravimeter surveys for gravity change detection lies in the fact that gravity change indicates elevation change . 用重力测量检测重力变化的意义在于，重力变化表示高程变化。
Finally, the hatch opens and, unaccustomed to the force of gravity, you stagger out amid venting waste gases . 终于，舱门打开，你蹒跚着（由于不习惯于重力作用）随舱内涌出的污浊气体走了出来。
