1. The silo-based DF-31 has a reported accuracy of 100m CEP, which is sufficient to destroy hardened missile silos if equipped with one of the higher yield MIRV warheads. 据称发射井式DF-31精度达到100米圆概率误差（CEP），如果装备使用一枚高当量MIRV弹头，足够摧毁硬化的导弹发射井。
2. The missile was fueled within the protection of its silo, and was raised to the launch position through doors at the top of the silo just minutes before launch. 导弹在其发射井的保护下加燃料，并在发射前几分钟通过发射井顶端的舱门升至发射位置。
3. The missile is expected to have an accuracy of at least 300m CEP, though it is reported that the silo and TEL-based version have 100 and 150m CEP respectively. 导弹精度期望具有至少300米圆概率误差(CEP)，虽然一些报道称发射井和竖立式运输发射架(TEL) -基分别具有100米和150米的圆概率误差(CEP)。
4. But in the actual silo measurement, the photograph of the missile is fuzzy because of the camera's quiver, the object's movement, and the defocus diffraction and so on. 实际井下测量过程中，存在相机振动、目标运动、离焦衍射等问题，导致拍照的图像模糊不清。
