| Abstract: | The paper is intended to give the data table of the component link calculation element based on the summary of the logical structure of data. This table is used as an object of calculation and a method to meet the needs for solution to assembly diamensional chain. With the fixing adjustment, the relation of calculation data is deduced. |
