论文摘要
我们回顾了原始磁盘的最新观察结果以及相关的理论研究，重点是挥发物的演变。在过去的几年中，Atacama大毫米/亚毫米阵列（ALMA）提供了谷物生长，气盘去耦和诸如粉尘连续性中的环和间隙等子结构的证据。分子线观测结果揭示了分子丰度的径向和垂直分布，并且还对诸如湍流等气体动力学的限制提供了重大限制。虽然亚毫米和毫米观测主要探测几个AU半径外的气体和灰尘，但在较短的波长下研究了冰和内部温暖气体。气体和灰尘动态是连接这些观察结果的关键。新兴趋势之一是元素丰度的不均匀分布，这很可能是由于粉尘 - 气体解耦。
We review the recent observations of protoplanetary disks together with relevant theoretical studies with an emphasis on the evolution of volatiles. In the last several years Atacama Large Millimeter/submillimeter Array (ALMA) provided evidence of grain growth, gas-dust decoupling, and sub-structures such as rings and gaps in the dust continuum. Molecular line observations revealed radial and vertical distributions of molecular abundances and also provided significant constraints on the gas dynamics such as turbulence. While sub-millimeter and millimeter observations mainly probe the gas and dust outside the radius of several au, ice and inner warm gas are investigated at shorter wavelengths. Gas and dust dynamics are key to connecting these observational findings. One of the emerging trends is inhomogeneous distributions of elemental abundances, most probably due to dust-gas decoupling.
