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.
作爲一個例子，還討論了弱重力場情況下激發流動重力模不穩定性的臨界條件。
Finite motion of massive scalar particle in gravitational field of a black hole with weak relativistic approximation is discussed.
討論了弱相對論近似下黑洞引力場中重質量標量粒子的有限運動。
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，介紹了引力輻射，主要是對引力場的線性化求解，即弱場近似作了介紹。
