| Abstract: | The linear symbol is classified according to the demand for symbol expressing, besides the data-structure of pattern cell of linear symbols is given combining with its visual variable. The paper bring forward the method of placement for linear symbols based on the characteristic of decomposition and combination about pattern cell of linear symbol. |
