Based on a hypothesis of function-equivalence which occurred not only in the mental folding but also object folding for individuals, this research indicated that individuals will search a fixed undersurface to fold up adjacent surfaces. Therefore, the type of unfold cube which had less undersurfaces and more adjacent surfaces could be more quickly for individuals to identify its undersurface, complete the mental folding and have better performance.

研究者以个体心像摺合时会与实物摺合存在功能相等性的假设，认为个体在心像摺合时会先寻找一个固定底面，再一起摺合所有邻面，因此底面数较少、邻面数较多的展开图类型会较快判定底面并完成心像摺合，而有较佳的表现。

Presenting the calculating method of the space displacement model of skewed box girder, whit main ideas of: dispersing the skewed box girder into some skewed beam segments and further dividing those segments into some plate pieces according to their forms; describing the displacement functions in the plane of plate piece by assuming that the space displacements of any point in the joint line between the plate pieces are described by using Hermite interpolation functions and that two displacements in the plane of plate piece are linear in the cross direction; Using Hermite interpolation functions to describe the bending the displacement of the unit length transverse frame cutting longitudinal from the skew box girder segment; Finally, describing the space displacements of a point in the plate pieces by two displacements in the plane of the plate and one bending displacement of plate.
