inflexion point meaning in English

反曲点
拐点
回折点

The instability in the natural convection boundary layer initiates with the buoyancy eigenmode and develops into non - linear stage with the turbulization of the buoyancy eigenmode . in the mean time , the invisid eigenmode at the inflexion point appears and begins to increase at the outer layer . experimental results show that the turbulent layer near the maximum velocity point can be detected while the reformed grashof number
自然对流边界层的稳定性由浮力振型失稳开始，并随着浮力振型的湍流化进入非线性阶段，与此同时，无粘性振型在外层开始失稳。实验结果表明，修正格拉斯霍夫数grashof
Compared to the basins in east guangxi , the basin of north guangxi is characterized by lower depositional and tectonic subsidence rate during rifting , longer thermal subsidence , later inflexion point from rifting to foreland buckling , as well as later inflexion point separating stable stage from active stage during foreland - buckling
但与桂东大瑶山地区相比，桂北兴安地区在裂陷阶段的沉积速率和构造沉降速率明显偏低；热沉降阶段的持续时间偏长；裂陷阶段与前陆挠曲阶段的分界拐点偏晚；前陆挠曲阶段，由构造宁静期的缓慢沉降向构造活动期的快速沉降转化的分界拐点也偏晚。
