Princess Catalina Kafu smiled and said: "And that phone Qingguo is still running a telegraph office, we not only already have telegraph technology, but also telephone technology" President Meng nodded: "Yes, this is also one of the most satisfying places for me this time, when Professor Nikola Tesla develops plastics, when the time comes, I want to make the entire Danzhou connected to electricity, telegraph, telephone, hundreds of kilometers away, I have a phone call, you can clearly know what I am thinking." ”Rob Cles Chief of General Staff admired Xuan Yuemeng's foresight, "President, this not only makes people's livelihood convenient, but also the cross-era progress of the army. ”President Meng nodded and said with a smile: "That's very good, Chief of General Staff Rob Chris, you participated in the American Civil War, and the army and navy are very familiar with it, and you have to pay more attention to the army construction in Danzhou in the future" Comrade Rob Criss Chief of General Staff was complacent, "President rest assured, don't dare to say anything else, among the middle and lower-level officers in the United States, my combat experience is very rich." ”President Meng smiled faintly, a middle and lower-level officer, I also dragged it badly, but it can only let you drag, two years of the army, five years of the navy, even if Danzhou has no military foundation at all, the speed will be doubled, and there should be no problem to cultivate a navy of its own within ten years, the key is still the problem of warships, or the problem of industry, and the people who operate a lot of people, and then what to do without warships As a colony, how difficult it is to buy armaments, President Meng has already learned that the telephone was invented by the Americans.Two wires are used to connect two transmitters and receivers with the same structure and a vibrating diaphragm on the electromagnet, and the two ends of the communication are realized first.However, the call distance is short and the efficiency is low.The charcoal essence microphone greatly improves the efficiency of the telephone transmitter.The receiver structure has also been improved.The earliest telephones were magnet telephones, powered by their own batteries and sent call signals by hand-cranked generators.President Meng needs the technical staff under him to transition the telephone to the common telephone as soon as possible, and change the power supply to the common power exchange, eliminating the need for hand-broadcast generators and dry batteries.Otherwise, the telephone in this era is still battery-powered, the distance is short, the signal is not good, and it is impossible to use the rotary dial pad automatic telephone in a large area, which can send out DC dialing pulses, control the automatic switch action, select the called user, and automatically complete the exchange function.Thus pushing telephone communication to a new stage.Not to mention that it suddenly looks like a modern telephone, at least it has to be like the young master Meng in the modern TV series, the hand-cranked style of ah as soon as possible to the dial-up style, you can promote it across the board, President Meng knows what the telephone opportunity has become, and it also saves the process of technical personnel taking detours, and the telephone is not a high-end technology in the first place, and President Meng's idea can increase the research and development speed of the telephone for ten or twenty years "President, we haven't named our warship yet" Princess Katrina Kafu suddenly thought of something and hurriedly reminded President Moe.President Meng thought for a while, "It's called Danzhou 1872 No. 1, it's easy to remember." ”Princess Katrina Kafu nodded, "It's okay, it's very easy to remember, but, let's just one warship, do you need to call it No. 1 No. 2" President Meng smiled: "I hope there can be No. 2, if not, it will be called Danzhou 1872 warship in the future." ”The middle and late nineteenth century was an extremely important stage for the development of the world's ships, and almost all later works on the history of warships and navies will mention this colorful golden age to a greater or lesser extent.During this period, with the rapid development of the industrial revolution, new technologies and inventions such as steam engines, steel armor, and breech guns continued to emerge, and the wooden sail warships that had dominated the seas for centuries reluctantly began to withdraw from the stage of history in the face of new technologies.People who are accustomed to admiring sail warships naturally find it difficult to accept this kind of "monster", at first, these strange-looking "magic ships" that spew black smoke and occasionally emit some fire were once used as a joke to laugh at and ridicule after dinner.In his famous book Maritime Laborers, the great French writer Victor Hugo, who described the struggle between man and nature, took the trouble to describe the details of this "magic ship" over and over again, as well as the views of people at that time.This makes it possible for us today to vividly and intuitively understand what happened to the ugly duckling when it came out.As you can see from the book, the great writer was fascinated by the "magic ship", but in those days, there were far more people standing on the shore waiting to see the ugly duckling come out of the ocean than to applaud.Fortunately, the wheel of history always moves forward, and the ugly duckling will one day become a proud white swan, and the days to come belong to them.Change seems to have happened overnight, and ship designers from all over the world are somewhat overwhelmed by the new technology, and they must now learn to constantly update their knowledge to meet this unprecedented challenge, or competition.In this competition, there is no precedent to follow, everyone is groping forward, trying to give full play to creativity and imagination, competing with each other, and occasionally there may be some "piracy" and "plagiarism".Perhaps it is for these reasons that today's people look back at the warships of that transitional period, and they will feel a little weird, and it is not an exaggeration to describe the various warship designs of this era.It is precisely with the exploration, development, experience and accumulation of technology in this ugly duckling era that the warship design ideas of various countries gradually matured and unified at the beginning of the 20th century.Coincidentally, the construction of the Chinese Navy also began in this era of ugly ducklings, and the era when the world's navies were renewing their warships with great fanfare was the age of the Chinese Navy.Like all warships in that era, the warships of China's modern navy also have a deep imprint of the times, and some of them have special designs that can be used as a model in the history of the development of ships in the world.In that era, ironclads were undoubtedly the overlords of the seas.This kind of iron-clad warship, which was developed from the battleships of the sail warship era, played the role of the main battle warship in the navy, and was used to participate in regular large-scale naval operations, and was the backbone of the navies of various countries and a symbol of national strength.t1706231537:
