传递性推理的心理效应主要包括端点锚定效应、系列位置效应、符号距离效应、一致性效应、转换效应、方向效应。
MENTAL EFFECTS of transitive inference, mainly include end-anchoring effect, translation effect, directional effect, serial position effect, and symbolic distance effect.
该模型采用二值化水平集方法实现，避免了传统实现方法水平集函数需要重新初始化为符号距离函数，从而导致稳定性差、计算量大、实现复杂等缺点。
The model was implemented by level set method with a binary level set function to reduce the expensive computational cost of re-initialization of the traditional level set function.
