在弱耦合I型弦理论中构造SO（32）旋量态作为快子场在D弦-反D弦对上的扭折解，并计算其质量。我们还给出了一个精确的边界共形场论的描述，并表明，在这种描述中，这种状态可以被视为一个非超对称的D 0-膜在I型弦理论。这种构造可以推广到把IIA型弦论中的D 0-膜表示为膜反膜对上快子场的涡旋解，把I型弦论中的D-弦表示为D5-膜反D5-膜对上快子场的拓扑孤子。
We construct the SO(32) spinor state in weakly coupled type I string theory as a kink solution of the tachyon field on the D-string - anti-D-string pair and calculate its mass. We also give a description of this system in terms of an exact boundary conformal field theory and show that in this description this state can be regarded as a non-supersymmetric D0-brane in type I string theory. This construction can be generalised to represent the D0-brane in type IIA string theory as a vortex solution of the tachyon field on the membrane anti-membrane pair, and the D-string of type I string theory as a topological soliton of the tachyon field on the D5-brane anti- D5-brane pair.
