With the rise of the water transport industry and the development of the shipbuilding industry, the ship load has become larger and larger, and the transportation capacity has also been greatly improved, so the requirements for channel navigation have also been improved.
Nam canalis etiam in plures gradus dividitur. Praeteritis, aquae profunditas requisita canalis non poterant occurrere navigationi exigentiis aquae areae, ideo necesse est ut puncta positionem praemonere in canali aquae vadoso admonere salutem navium navigantium. Talia signa plerumque utuntur plastic
buoys to ensure that only ships on water can see them. At night, the buoys are equipped with solar beacon lights to ensure that they can be seen from afar and work. Some channels will be connected to the LAN according to the use requirements, and displayed on the radar, so that passing ships can be displayed and marked on electronic equipment, so that the preparation time can be adjusted in advance to avoid danger.
Aquae canalis plastici saxum efficiunt altae fortitudinis polyethylenae plasticae per technologiam rotativam corona. Patet utilitas huius materiae est quod bonam corrosionem habet resistentiam et resistentiam gerunt, et in asperis marinis ambitu diu adhiberi potest. Cum subsidiis navigationis ferro primis comparatis, canalis onera plurima multa commoda habent, ut sustentationem gratuitam, gravem gratuitam ac diuturnam vitam serviunt.
