显式构造了一种相似变换，它将一类特定的N=1串带入N=0的串中。它使我们能够为Berkovits和Vafa最近提出的论点提供一个简单的证明。将N=1的BRST算子转化为相应的N=0 BRST算子与另一个拓扑扇区的直和。结果表明，这些N=1真空的物理谱与N=0谱和仅由真空组成的拓扑区的张量积同构。这种变换明显地保持了算子代数。
A similarity transformation, which brings a particular class of N = 1 strings to those with N = 0, is explicitly constructed. It enables us to give a simple proof for the argument recently proposed by Berkovits and Vafa. The N = 1 BRST operator is turned into the direct sum of the corresponding N = 0 BRST operator and that for an additional topological sector. As a result, the physical spectrum of these N = 1 vacua is shown to be isomorphic to the tensor product of the N = 0 spectrum and the topological sector which consists of only the vacuum. This transformation manifestly keeps the operator algebra.
