inner region

It is shown that the inner and outer regions of Tropical Cyclone have different governing equations. The inner region is governed by the cyclonic wind and an evolution equation, the outer region is governed by the gradient wind and another evolution equation.

研究表明，热带气旋内区和外区有不同的控制方程，内区受旋转风和一个演化方程制约，而外区受梯度风和另一个演化方程制约。

The results show that the perturbed peak density of linear density wave grows to the same order as the basic state density during merely tens of million years, the spiral pattern emerging which has barred structure in its inner region.

数值计算结果表明，线性密度波将在几千万年时间内增长到与基态同量级，形成在中心区域具有棒形结构的螺旋图样。

QPO is believed to be an effective approach to detect the accretion process near BHs since its time scale is equivalent to the dynamical time scale in the inner region of an accretion disk.

由于其时标与黑洞吸积盘内区的动力学时标相当，QPO被认为是探测黑洞附近吸积过程的有效途径。
