The size of the picture of the whole foundation is too tall in precision (specific size has reached 0.01 millimetres), far go beyond the national standard, and unable to reach this precision at all in the参考资料：http://tran.httpcn.com/ 已赞过已踩过<
The size of the entire foundation plans high precision , leaving the country far exceeds the standard, but also in civil engineering construction simply can not reach this precision, we propose to retain the dimensional accuracy to the centimeter level.
