They are movable recently. We should often pay attention to the problems found in the use of the experimental machine. 4. Experiments and data processing can be carried out according to GB, ISO, ASTM, JIS and other standards
it is understood that after the completion of the project, the Hasi highway bridge to dajingjia section of national highway 202 will be changed from the current 4 lanes to 6 lanes. The total length of the project is 8.63 kilometers, the width of the red line is 124 meters, and the design speed is 40 kilometers per hour. For a 2V signal, it can only provide 6A current instead of 30/2=15a Li to 80 kilometers per hour. The estimated investment of the project is 370million, and it is expected to be completed and opened to traffic before the end of the year
