原恒星盘在垂直于盘平面的方向上对热对流是本质上不稳定的。我们构造线性化控制方程的非轴对称解，以确定无粘绝热圆盘中对流不稳定性的性质。我们发现可能存在导致角动量向外输运的不稳定扰动
Protostellar disks are intrinsically unstable to thermal convection in the direction normal to the plane of the disk. We construct nonaxisymmetric solutions of the linearized governing equations in order to determine the properties of convective instabilities in inviscid adiabatic disks. We find that there can be unstable disturbances which result in outward transport of angular momentum
