我们调查的一般问题，实施手征MSSM一样的D-膜部门在IIB型orientifold模型通过F-项诱导通量和时空瞬子，分别Gaugino凝聚完全模稳定。原型例子是KKLT和所谓的大体积紧致化。我们表明，首先通过F-项稳定所有模量，然后引入标准模型模块是误导，作为一个手征部门臭名昭著的影响结构的非微扰效应，并诱导D-项潜力。为了更具体地研究大体积情形，我们给出了swiss-cheese型Calabi-Yau流形P_[1，3，3，3，5][15]_（3，75）的几何结构，并分析了通过F-项和D-项的组合是否能实现可控的和唯象上可接受的Kaehler模稳定化。
We investigate the general question of implementing a chiral MSSM like D-brane sector in Type IIB orientifold models with complete moduli stabilisation via F-terms induced by fluxes and space-time instantons, respectively gaugino condensates. The prototype examples are the KKLT and the so-called large volume compactifications. We show that the ansatz of first stabilising all moduli via F-terms and then introducing the Standard Model module is misleading, as a chiral sector notoriously influences the structure of non-perturbative effects and induces a D-term potential. Focusing for concreteness on the large volume scenario, we work out the geometry of the swiss-cheese type Calabi-Yau manifold P_[1,3,3,3,5][15]_(3,75) and analyse whether controllable and phenomenologically acceptable Kaehler moduli stabilisation can occur by the combination of F- and D-terms.
