利用等效欧几里得晶格场理论，证明了通过断裂和连接相互作用的闭合Nambu-Goto弦的路径积分表达式是病态的。讨论了纠正这一问题的一类相互作用。导出了弦真空期望值的Dyson-Schwinger方程。
A path integral expression for closed Nambu-Goto strings interacting by breaking and joining is shown to be pathological by using an equivalent euclidean lattice field theory. A class of interactions which correct this problem is discussed. Dyson-Schwinger equations are derived for string vacuum expectation values.
