研究了广义条件期望下量子晶格系统的马尔可夫性。指出了量子马氏场的一般性质(特例)，即具有多维指标的量子马氏过程。这样，与KMS边界条件的深层联系以及相变和对称破缺现象就自然而然地出现了。
The Markov property for quantum lattice systems is investigated in terms of generalized conditional expectations. General properties of (particular cases of) quantum Markov fields, i.e. quantum Markov processes with multi-dimensional indices, are pointed out. In such a way, deep connections with the KMS boundary condition, as well as phenomena of phase transitions and symmetry breaking, naturally emerge.
