利用镜像对称性，我们确定并总结了IIA型弦的Calabi-Yau三重紧化中超多重态模空间度规的一类膜瞬子修正。这些修正与IIB侧的D1和D（-1）-膜瞬子是镜像的，并且在射影超空间中以单个函数的形式明确给出。相应的四维有效作用量由镜像卡-丘的欧拉数和亏格为零的Gopakumar-Vafa不变量完全固定。
We use mirror symmetry to determine and sum up a class of membrane instanton corrections to the hypermultiplet moduli space metric arising in Calabi-Yau threefold compactifications of type IIA strings. These corrections are mirror to the D1 and D(-1)-brane instantons on the IIB side and are given explicitly in terms of a single function in projective superspace. The corresponding four-dimensional effective action is completely fixed by the Euler number and the genus zero Gopakumar-Vafa invariants of the mirror Calabi-Yau.
