IIB型弦理论的s -对偶对称性预测了IIB型弦理论的轨道五平面上存在一个稳定的非bps态，如果轨道群是由（−1）FL的同时作用和与轨道平面横向的四个坐标的符号反转产生的。我们从一对携带与该状态相同电荷的d弦开始计算该状态的质量，然后在模空间中确定这对d弦发展出速子模式的点，标志着该构型的束缚态进入非bps状态的出现。
S-duality symmetry of type IIB string theory predicts the existence of a stable non-BPS state on an orbifold five plane of the type IIB theory if the orbifold group is generated by the simultaneous action of (−1)FL and the reversal of sign of the four coordinates transverse to the orbifold plane. We calculate the mass of this state by starting from a pair of D-strings carrying the same charge as this state, and then identifying the point in the moduli space where this pair develops a tachyonic mode, signalling the appearance of a bound state of this configuration into the non-BPS state.
