Two models have been proposed to explain molecular mechanism of Dkk's inhibition role in canonical Wnt pathway: in the first model, Dkk1 competes for binding of Wnt co-receptor LRP6; in the second model, Dkk1 can form a ternary complex with LRP6 and Kremen at the presence of Kremen, and triggers the endocytosis of this ternary complex quickly. The controversies between these two models exist during these years.

现今有两种模型分别解释Dkk抑制经典Wnt信号的分子机制：在第一种模型中，一些研究者认为Dkk1主要通过在细胞外与配体Wnt竞争受体LRP6从而抑制Wnt信号；在第二种模型中，另一些研究者们则认为在Kremen存在的情况下，Dkk1通过诱导形成Dkk1-LRP6-Kremen三元复合物，并迅速诱导这个三元复合物的内吞从而发挥抑制功能。

After studying this phenomenon, the author finds that, the covariance matrix of the complex expressions of horizontal gradients of the disturbing gravity field elements has a structure of blockwise repetitive Toeplitz matrix, though the covariance within the disturbing gravity field elements is still anisotropic. Therefore, the collocation problem of the complex combination of horizontal components is similar to that of gravity anomaly, which makes the degradation be able to be completed by FFT transformation matrix.

作者研究发现，利用水平梯度的复组合，即复数表示后，扰动重力场元复组合之间的协方差函数尽管还是各向异性，但它们对应的协方差矩阵却具有分块 Toeplitz 循环阵的结构，因而水平分量复组合的配置问题与重力异常的配置问题相似，可以利用傅立叶变换矩阵进行降阶处理。

After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.
