"Big brother, the New Year is coming soon, and we have a new little nephew in our family, I think we should celebrate the New Year this year." Yang Hu is now organizing sports competitions, and there are some other gatherings that are becoming more and more convenient, naturally, thinking about the opportunity for Yang Heng to add a new child, the Yang family has a good celebration.

"Oh, how do you say you celebrate?" Yang Heng looked at Yang Hu with interest, he liked the appearance of these younger brothers, they all began to have their own say in their respective fields, and they were all aggressive, it seems that the Yang family would prosper for fifty years without Yang Heng.

"Big brother, isn't there a time when there is no curfew, now for the New Year, you can apply to Your Majesty, and ask Your Majesty to allow the curfew in Chang'an City to be released for a few days during the New Year, and our family can organize a few big parties, which will be held in the big stadium, and it will be a good time, and it can be regarded as a celebration for the little nephew."

"Cheng, you can do this, for the New Year, it is estimated that I have no time at home, that is, I will come back once in a few days, I want to go to the ship, I have not paid attention to the construction of the railway for a long time, and it seems that some problems have accumulated, and the shipyard is waiting for me to cut the ribbon for the opening of the shipping train."

"Nacheng, I hope that when the eldest brother comes back, he can take a look at the party we held, and then the younger brother will hold it according to this meaning." "You go and hold it, I will send a fold to Your Majesty, it is estimated that he can allow the curfew to be lifted during the New Year, by the way, I think you can add some things like the garden lantern festival, it is best to hold it until after Shangyuan." Our Yang family is not bad for those money, remember, don't advertise to others this time. Only do our family, there are also advertisements for Changle and Yuzhang, if the royal family needs it, you can also do some advertising for the royal family. ”

Since it is some big event, it is naturally the best time for advertising, Yang Heng naturally can't miss it, and he knows it. This opportunity is only this once, and after this time, Li Er will definitely focus on this matter. At that time, if it is held at home, it will be unlikely, and it will definitely be dominated by the imperial court.

But. Yang Heng believed. This first session must be the best, and then the next, just like the spring party in the previous life, is not as good as the year, although there is no TV now.

"Big brother, don't worry, I will definitely be able to make this party beautiful, you can do your business with peace of mind." "Yang Hu. This evening, I think. You should find Xiaoniang, as well as the baby and others to ask some of their opinions, you don't underestimate the baby, for the child's thoughts, or listen to the baby. Suddenly, Yang Heng remembered that Xiao Niang was a big part of the content, and she could add a lot of programs after her, and the baby, they were able to add some children's programs, you know, since it is a party, there are some other activities, naturally there are children indispensable, if there is no content that children like, there will be a lot fewer people to watch.

"Xuewen, you're here, quick, come with me first, this is the first time that this ship has been fully combined, and only two boats have been combined before, and those technicians are in a hurry to carry out a full combination test?" As soon as Yang Heng arrived, the uncle anxiously pulled Yang Heng to the scene of the dock.

"Uncle, uncle, you let me take a breath first, let me warm up first, okay, I'm in a hurry to take a balloon." Yang Heng said with a helpless smile.

"Haha, look at me, I'm also in a hurry, okay, you can go to the room to warm up first, when you're warm, I'll tell you about the winter situation here." As he spoke, he let Yang Heng into the house, and as soon as he arrived in the house, Yang Heng took off the thick clothes on his body, in the sky, but he froze him, although he was guarding the steam engine, the heat of the boiler could make him warm, but he could only keep warm on one side, and the other side was cold and cold, this is really two layers of ice and fire.

"Xuewen, we ignored one thing, that is, this section of the river is also frozen in winter, but fortunately, I asked a lot of people around me, the memory of the past fifty years is that the ice here will not be very thick, in this way, we built a separate icebreaker, that is, this ship, to break the ice once a day, otherwise, there is really no way to let the train open, you know, the train is not divided into winter and summer, must be opened, there is another problem, that is, there is a dry period, and there is a high water period, This is another problem, so, on the ship, we also installed some counterweight facilities, that is, add a few water tanks, once it is in the dry season, we will pump out the water in the water tank, and in the high water period, we will fill the water tank, so as to ensure that at any time, the rails on the ship are in a horizontal state with the rails on the shore, so that there will be no accidents, you know, the transport train, there are people on it, once an accident happens, this train can carry one or two thousand people, if it is three trains crossing the river at the same time, There would be more of that. "Uncle, I said a few things, these are some of the main problems he has noticed during this period of time, these are really not expected by Yang Heng, it can be seen that Uncle is already quite serious about doing things now.

"Uncle, you still have a question that you haven't noticed, what if there is a boat walking on this river, and it happens to meet our boat carrying trains, this matter is not nothing." "Ah, this, I really didn't expect it, would they bump into it?" "Uncle this can't help but prevent, you haven't hit it for a month, once you haven't hit it for two months, it's not broken, so, I think, we should install a few interception nets in the upstream and downstream, every time the ship is opened, we have to pull up the interception net, the downstream is basically nothing, the upstream, just let the interception net be stopped, and the main thing is to pay attention to the upstream ships, their momentum is the greatest."

"Cheng, I wrote down this matter, if you don't say it, you really ignore it, if there is really a ship that has no time to dodge, then something big will happen." Uncle thought about it, but also shocked a cold sweat, this, he really didn't think of it, even the people in the shipyard didn't think of it, this is a misunderstanding of thinking, they will think that the river is so wide, naturally there will be nothing, they will naturally avoid the past, just did not expect the appearance of accidents, in this way, the upstream ship will be the most dangerous, and the downstream to the upstream ship, there is no danger, but, in the future, after the steam engine is installed on the ship, the upstream and downstream will also have the risk of collision.

But if you add the interception net, it will be different, although this interception net is a little too long, but for safety reasons, it is still necessary to develop, and initially, it is completely possible to arrange several ships on duty upstream and downstream.

"Or, uncle, you can set up a few traffic command boats on the river, upstream, when a boat comes, let them command, let it avoid our boat far upstream, and then pass by from the side, I know, this interception net is not a day or two can be done, this also needs to let the scientific research part of the academy conduct some research, what kind of materials are used in this interception net, how to collect and release, how to use for communication, these are all things that need to be developed."

This interception net will not be used for a long time in Yang Heng's mind, Yang Heng estimates that in a few years, maybe there will be new technology, and you can build a bridge directly in the river, and at that time, this ship to transport trains will not be used.

"Xuewen, there is another question, that is, about the problem of the marine steam engine, now, the propeller or something can be used, but, as a steam engine, it is not too suitable for use on the ship, now the steam engine we use, are the steam engines on the train directly moved to the ship, I think, you should avoid these steam engines for improvement, transform the steam engine suitable for the ship, but also have a variety of different sizes of models, this ship is really different from the train, the ship is divided into sizes, However, there is no difference in size of the train, so the steam engine used on the ship is the size of the power and the size of the body, which are all related. ”

"Well, I've made a note of this, and I'll have the Train Factory Power Plant add a research on a marine steam engine project, or maybe we'll make a steam engine for land use and put it on a wagon." Well, in that case, there should be a small steam engine, which can make cars at all. (To be continued......)
