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。

Besides that, we presents the gravitational wave energy density under the weak field situation and gives the x - y plane numerical calculation to curvature scalar R and energy density .

还有计算了在弱场条件近似下引力驻波的能量密度，并给出曲率标量R和能量密度平面的数值计算。

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。
