寻找空间/时间的非对易性，我们重新考虑开弦在一个恒定的背景电场。这种情况与磁对应情况的主要区别在于，这里存在一个临界电场，超过这个电场，理论就没有意义了。我们表明，这一关键领域阻止我们找到一个限制，在该理论成为一个非对易时空的场论。然而，对临界场的适当限制会导致非对易时空上的新颖非临界弦理论。
Searching for space/time noncommutativity we reconsider open strings in a constant background electric field. The main difference between this situation and its magnetic counterpart is that here there is a critical electric field beyond which the theory does not make sense. We show that this critical field prevents us from finding a limit in which the theory becomes a field theory on a noncommutative spacetime. However, an appropriate limit toward the critical field leads to a novel noncritical string theory on a noncommutative spacetime.
