Wide provided suitable for busy trunk, also can be laid in tunnel and station floor maintenance difficulties, stone or soil subgrade are laid, but the mud pumping in the diseases of roadbed must be laid on the roadbed diseases after renovation. The main advantages of the wide sleeper circuit are: the suborbital sinking is small. The vibration acceleration is smaller than the concrete sleeper line, which gradually slows down and stops after laying. So the line maintenance work is greatly reduced, about a third of the general concrete sleeper line. The track is easy to keep clean. Dirt is not easy to break into the bed and prolong the repair cycle of the route. The line is smooth and stable, which is conducive to high-speed operation and the laying of seamless circuit. The disadvantage is that the cost is higher, and it is more difficult to change the shop on the busy trunk line
Americans value teamwork, and tolerance is one of their most cherished cooperative foundations, because they know it's a real team strategy to retreat. Hugo once said, "the broadest sea is the sea, the sky is wider than the sea, and the sky is more broad than the sky." This is true whenever and wherever, even in a competitive job market, tolerance is a shortcut that allows you to fit in as quickly as possible. Tolerance is the best lubricant in teamwork, it can eliminate conflicts and wars, enable team members to weight each other, each other, harmony, and focus on their work, experience the joy of cooperation. Just think, if you're furious at someone, even if it's your fault, no one can guarantee that he won't retaliate against you in the same manner. In this way, the contradiction is inevitable.
