随着第二代完整稳性衡准的制定，作为一种独特的波浪中稳性问题，纯稳性丧失衡准即将在未来几年内作为建议性要求被国际海事组织（IMO）颁布执行并应用于实船设计。而当理论研究成果向实际工程应用转化时，有必要进行大量适用性研究以便勘验、提高该方法的鲁棒性。论文介绍了基于经验公式的Level 1衡准和基于分析波浪中考虑物面非线性影响 GZ 曲线特征的 Level 2衡准方法，通过分别采用这两种方法针对不同类型38条实船的数值预报研究，分析了不同船型、尺度和装载工况的实船设计对于纯稳性丧失衡准的敏感性。在此基础上介绍了适用 Level 2衡准的两种进水角计算方法，通过对比分析了两种进水角计算方法对于敏感性预报结果的影响及其适用性。根据以上研究，对 IMO 现有衡准方案存在的问题提出了若干改进建议。

Pure loss of stability criteria has been developed and contained in the second generation intact stability criteria, and will be applied in the design of full-scale ships in the next few years. It is necessary to improve the robustness of the criteria through large number of sample calculations. In this paper, Level 1 and Level 2 criteria are introduced. Based on numerical sample calculations for 38 full-scale ships, the vulnerability of pure loss of stability is analyzed with different types, scale and loading conditions. Two possible methods of calculating inlet angle are introduced and compared. Some improvement recommendations for IMO’s draft criteria are put forward.
