在弦的第一种量子化方法中，众所周知，弦耦合常数由膨胀场的真空期望值决定。然而，这种性质从未在弦场论的框架内得到证明。在闭玻色弦的光锥场论中，我们构造了一个与玻色子真空期望值和弦耦合常数的位移有关的弦场的显式重参数化，它表现出上述性质.
In the first quantized approaches to strings, it is well known that the string-coupling constant is determined by the vacuum expectation value of the dilation field. This property, however, has never been demostrated within the framework of string field theory. An explicit reparametrization of the string field associated with the shifts of the dilaton vacuum expectation value and the string-coupling constant is constructed exhibiting the above property in the light-cone field theory of the closed bosonic string.
