Some ship introductions:
1, raft age
Humans use rafts as a tool for transportation, hunting and fishing, which originated at least in the Stone Age. 1956 The ancient wooden paddle unearthed by China in Zhejiang was identified as a Neolithic relic 4,000 years ago. Explain that the history of rafts can be traced back to prehistoric times.
2. The age of navigation
According to records, there were sailboats in ancient Egypt as far back as 4000 BC. The history of China's navigation can also be traced back to BC. 15th century to19th century is the heyday of sailing development. /kloc-at the beginning of the 5th century, Zheng He, a China navigator, sailed to East Africa./kloc-at the end of the 5th century, C. Columbus discovered the New World, and their fleets were all made up of sailboats.
In the history of sailing development, Mediterranean coastal areas, northern and western Europe and China have made great contributions. /kloc-in the middle of the 0/9th century, American sailing was the last climax in the history of sailing development. Sailing boats in different areas have their own characteristics in structure, form and sails.
3, the steam engine ship era
/kloc-after the invention of the steam engine in the 0/8th century, many people tried to use the steam engine on ships. 1807, American R. Fulton sailed successfully on the Hudson River for the first time by using a steam engine to drive paddle wheels installed on both sides of the clermont. From then on, mechanical force began to replace natural force, and the development of ships entered a new stage.
4. The era of diesel ships
After the diesel ship came out, it developed rapidly and gradually replaced the steam ship. After World War II, the rapid economic recovery and development of industrialized countries, the unprecedented prosperity of international trade, and the massive development of oil in the Middle East and other places have promoted the rapid development of transport ships.
