weak gravitational field

基本解释

As an example, the critical condition for the streaming gravity mode instability is discussed in a weak gravitational field.
作为一个例子，还讨论了弱重力场情况下激发流动重力模不稳定性的临界条件。
Finite motion of massive scalar particle in gravitational field of a black hole with weak relativistic approximation is discussed.
讨论了弱相对论近似下黑洞引力场中重质量标量粒子的有限运动。
In chapter two, it explains gravitational radiation, especially the linear solution in gravitational field. That means it gives explanation to weak field.
在第二章中，介绍了引力辐射，主要是对引力场的线性化求解，即弱场近似作了介绍。
