The principle of hot-air balloon is very simple, manufactures to have two difficulties \; first, combustion train \; second, air bag. 热气球的原理很简单,制作起来只有两个难点,一是燃烧装置,二是气囊。 The first point in not having pressure vessel provides the gaseous fuel under situation, depends on the fuel or the charcoal only heats up the air, the efficiency did not say lowly, cannot be flown by the fuel limit far. This was historically very much long time ago had also discovered hot-air balloon principle, but in the actual combat put into the utilization is actually the hot air balloon reason. Therefore Roland simply gives up the combustion train, lets Anna the ignition heating. 第一点在没有压力容器提供气体燃料的情况下,单靠柴火或木炭来加热空气,效率低不说,受燃料限制也飞不了多远。这也是历史上很早就发现了热气球原理,但在实战中率先投入运用的却是氢气球的原因。所以罗兰干脆放弃燃烧装置,让安娜来点火加热。 The air bag difficulty lies in the stopping property, Roland that but regarding drawing on the predecessor has experienced, this issue is very easy to solve-- to use the band cotton material then. air bag most outer layer for wear-resisting canvas, middle lining has ox Chang the epithelium, the inner layer for the facile gauze, like this sutures then to prevent the air leakage, simultaneously does not fear the pecking of birds to strike. 气囊的难点在于密闭性,不过对于借鉴了前人经验的罗兰来说,这个问题很容易解决——采用夹层布料即可。气囊最外层为耐磨的帆布,中间衬有牛肠皮膜,内层为轻便的纱布,这样缝合起来即可防止漏气,同时不惧怕鸟类的啄击。 Roland opens bottom of air bag, making Anna spout the temperature and ordinary flame close black fire toward inside, the air bag ballooning gets up slowly, seems like one full is the fold winter melon. Considered that the hot-air balloon needs to carry two people to lift off, the air bag widest place diameter has five meters fully, has used up 12 good intestines epithelia, sews work close one week. If no jurisdiction over place feudal lord, but also varies to make to order like this big toy. 罗兰撑开气囊底部,让安娜往里面喷出温度和普通火焰接近的黑火,气囊慢慢鼓胀起来,看上去就像一只满是褶皱的冬瓜。考虑到热气球需要搭载两人升空,气囊最宽处直径足有五米,用掉了12头牛的肠皮膜,缝制工作接近一周。如果不是管辖一地的领主,还真不一定造得起这样的大玩具。 „It flies with the aid of the buoyancy that the steam does provide?” Anna asked that „I remember that in book once had mentioned, hot air always to rise.” “它是借助热气提供的浮力飞起来吗？”安娜问道,“我记得书里曾提到过,热空气总是向上升的。” „Right, the hot air rises, the cold air submersion is the common natural phenomenon. Explained with the particle theory, is hot air small ball movement intensifies, spreads ability that to all around, after volume expansion , the density will change will be small. Regarding peripheral does not have the air of change, its quite in Bianqing, will therefore rise.” “没错,热空气上升,冷空气下沉是常见的自然现象。用粒子理论来解释,便是较热的空气小球运动加剧,向四周扩散的能力强,体积膨胀后密度会变小。对于周边没有变化的空气来说,它相当于变轻了,因此会上升。” After Roland lecture principle, discovered that besides Anna reveals " So that's it " expression, other three people are bewildered, making him secretly sigh importance of talent. 罗兰讲完原理后,发现除了安娜露出「原来如此」的表情外,其他三人都是一脸茫然,让他不禁暗自感叹天赋的重要性。 When the air bag complete expansion upwardly floats off, the traction rope was flared-out slowly, Roland turns into the hanging basket, afterward received to turn crawls Anna. 当气囊完全膨胀并向上浮起时,牵引绳索被缓缓拉直,罗兰率先翻入吊篮内,随后接过翻爬中的安娜。 „I am somewhat was worried,” Nightingale restless say/way, „, or you make me come up to try first.” “我还是有些担心,”夜莺不安道,“要不您让我先上去试一试吧。” „Believes me, will not have an accident,” Roland smiled with ease, „, and has the accident/surprise, Lightning.” “相信我,不会出什么事的,”罗兰轻松地笑了笑,“而且就算发生意外,还有闪电在。” „I will catch their, relax.” Lightning has patted striking one's chest. “我会接住他们的,放心吧。”闪电拍了拍胸脯。 „me too gu!” Macy studies the Lightning appearance to strike one's chest to say. “还有我咕！”麦茜学着闪电的模样拍胸脯道。 As sways, the hot-air balloon pulls the hanging basket to leave the ground, gradually climbs upwardly. Shortly, two people then crossed the castle peak, small town complete one by one presents before them. 随着一阵摇晃,热气球牵着吊篮离开地面,逐渐向上爬升。没多久,两人便越过了城堡顶端,小镇的全貌一一呈现在他们面前。 To Roland, such scene is not strange, after all he has also seen the person in modernization, but in the Anna eye, was type and the past angle of view entirely different brand-new experience. She lies near the hanging basket the probe head looks around outward, a hand firmly holds the arm of Roland, appears is excited and anxious. 对罗兰而言,这样的景象不算陌生,毕竟他也是见过摩天大厦的人,但在安娜眼里,便是种与以往视角截然不同的全新体验了。她趴在吊篮边探头向外张望,一只手牢牢抓住罗兰的胳膊,显得即兴奋又紧张。 This is Roland first time sees her to show such facial expression, the general both feet has never been far away from the person in ground, when flies for the first time to the sky, will have the slight high sensitivity perhaps. 这还是罗兰第一次看到她露出这样的神情,大概双脚从未远离过地面的人,首次飞向天空时,都会产生轻微的恐高感吧。 Before long, under the hanging basket for tying up the hemp rope of hot-air balloon by pulling the limit, the rise was stopped. Hemp rope approximately 50 meters, is the altitudes of later generation 15-16 buildings. Roland makes Anna reduce the firepower, hot-air balloon finally hovering in airborne. 不一会儿,吊篮下方用于拴住热气球的麻绳被拉到了极限,上升停止了。麻绳约50米长,也就是后世十五六层楼的高度。罗兰让安娜减小火力,热气球最终悬停在空中。 When Lightning from the beginning also proximally defends near the hanging basket, after seeing the basket stability, feels relieved, played the chase game with Macy around the hot-air balloon. 闪电一开始时还寸步不离地守在吊篮边,见到篮子稳定后也放心下来,跟麦茜绕着热气球玩起了追逐游戏。 Looks downward from here, can see Scarlet Water River that small town that clearly castle roof, everywhere constructed, flows from west to east, as well as riverside emerald green farmland. 从这里向下望去,可以清晰地看到城堡屋顶、到处都在施工的小镇、由西往东流淌的赤水河,以及河边翠绿的农田。 „How feels?” “感觉如何？” Until the Anna retracting head, Roland with a smile asked. 直到安娜缩回脑袋,罗兰才笑着问道。 „Gift thank you,” she was excited said, „originally I can also fly to be so high.” “谢谢您的礼物,”她兴奋得说,“原来我也能飞这么高。” „Also can be higher,” Roland pastes the rattan hanging basket sidewall to sit down, „, if following hemp rope again long, flies ten times not to have the issue in this's distance, but upward the air current is more complex, the security was hard to safeguard. Moreover this is only the primary flight vehicle, waited later to make the piston machine, the average person has also been able to fly to be quicker than the bird, was higher than the bird,......” he will look up the eye deep blue sky again in the future, „people even can depart this world, went to the limitless outer space.” “还可以更高,”罗兰贴着藤条吊篮侧壁坐下,“如果下面的麻绳再长点,飞个十倍于此的距离都没问题,不过越往上气流越复杂,安全性就难以保障了。而且这只是初级的飞行器,等以后造出了活塞机,普通人也能飞得比鸟更快,比鸟更高,再往后……”他抬头望了眼蔚蓝的天空,“人们甚至可以飞出这个世界,前往无边无际的太空。” „......” Anna has turned very quiet, in her eye pupil sparkles to shine, has any thing to be vivid. “……”安娜屏住了呼吸,她的眼眸里闪闪发亮,有什么东西呼之欲出。 „Departs the world I unable to guarantee,” Roland provoked smiling by her appearance, „, but makes the piston machine, letting the average person can look like the bird to soar generally, the lifetime should be able to achieve.” In fact some Anna, working capacity did not have the bottleneck, the current short board exists in the material characteristics. Inferior pig iron can assemble is making Steam engine, the wrought iron can produce the artillery, makes the revolver weapon issue not to be big with the steel that the black fire smelts, perhaps but the words of internal combustion engine, must need the high qualitative cast iron, cast steel or the aluminum. „Border Town can have the present appearance, all these are your merit, " Miss Anna " .” “飞出世界我不敢保证,”罗兰被她的模样逗笑了,“但造出活塞机,让普通人能够像鸟儿一般飞翔,有生之年应该还是能做到的。”事实上有安娜在,加工能力已不存在瓶颈,目前的短板存在于材料性能上。劣质生铁可以凑合着造蒸汽机,熟铁可以造炮,用黑火冶炼出的钢造转轮枪械也问题不大,但内燃机的话,恐怕得需要高品质的铸铁、铸钢或铝了。“边陲镇能有现在的样子,这一切都是你的功劳,「安娜小姐」。” After hearing these words, Anna was startled. Crossed some little time, she depends to sit, opens the mouth to say in a soft voice, „my mother dies of a fire, but I not only have not been buried in the thick smoke and raging fire, instead became witch. Has a long time, I once think that was my awakening has caused this fire , the extreme loathing was witch. When was closed in the jail, is thinking like this could welcome the extrication, you have actually saved from the firmness me, taught how I use the ability...... I have not thought, the flame besides bringing to burn down with the pain, but can also have so many uses.” Anna paused, „can meet you, I should feel extremely satisfiedly, but I discovered that now my idea changed, sometimes will think that at heart is much more oppressed, hopes to obtain.” 听到这句话后,安娜怔住了。过了好一会,她才靠坐过来,轻声开口道,“我的母亲死于一场火灾,可我不仅没有葬身于浓烟和烈火中,反而成为了女巫。有很长一段时间,我曾以为是我的觉醒导致了这场大火,也极度厌恶身为女巫的自己。被关在监牢里时,本想着这样或许能迎来解脱,您却把我从牢中救了出来,教导我如何使用能力……我没有想到,火焰除了带来焚毁和痛苦外,还可以有如此多的用处。”安娜顿了顿,“能遇上您,我应该感到万分满足的,可现在我发现自己的想法已经变了,有时候会觉得心里憋闷得难受,希望得到更多。” She climbs up the shoulder of Roland, „, even if in this case, you also do want to hire me?” 她攀上罗兰的肩膀,“即使这样的话,您还想要聘用我吗？” In her lake blue color eye wave light is clear, the breath blows on the face, somewhat itchy feeling. Is away from the frail clothing, he can feel the opposite party soft body and bang bang the heartbeat. Nevertheless, she has not avoided vision orthoptic--, when does not have Nightingale, she is always soulful and initiative. 她的湖蓝色眼睛里波光粼粼,呼吸吹在脸上,有些痒痒的感觉。隔着单薄的衣物,他能感受到对方柔软的身躯和砰砰的心跳。尽管这样,她也没有避开目光的直视——在没有夜莺的时候,她总是充满热情和主动。 „Outside has......” “外面有……” Roland has not said, Anna has sealed up his lip. 罗兰还未说完,安娜已经封住了他的嘴唇。 After separating, he gasped for breath gently, „I want to hire you, continuously. Miss Anna.” 分开后,他轻轻喘了口气,“我想要聘用你,一直。安娜小姐。” „Yeah.” “嗯。” This time, he lowered the head on own initiative, pastes to gather together with her in the same place. 这一次,他主动低下头,和她贴拢在一起。 ...... …… „Well, wait/etc.,” Macy pursued Lightning a while, suddenly sharply stops in airborne one, looks to the empty hanging basket, „they disappear gu!” “咦,等等,”麦茜追了闪电一会儿,忽然在空中一个急停,望向空荡荡的吊篮,“他们不见了咕！” „Ah?” Lightning looked at one, „they sat.” “啊？”闪电偏头望了一眼,“他们只是坐下来了啦。” „Couldn't such see outside scenery?” “那样不就看不到外面的风景了吗？” „Scenery momentarily can look, but such opportunity are not many.” “风景随时都能看,但这样的机会可不多。” „Opportunity?” Macy shakes the wing, falls on the Lightning shoulder, „is not very clear gu, can have a look at their gu?” “机会？”麦茜抖抖翅膀,落在闪电肩头,“不是很明白咕,要不要去看看他们咕？” „That is not good,” Lightning holds in the arms the pigeon, „this is a sacred ceremony, cannot be broken.” “那可不行,”闪电一把搂住鸽子,“这是一场神圣的仪式,是不能被打断的。” „gu?” “咕？” „In brief, later you understand that at this time, when so long as has not seen well, this is my father-- greatest explorer tells me.” Lightning ejects Macy, forks the waist saying that „the present runs, changed me to pursue you!” “总之,以后你会明白的,这种时候,只要当没看到就好,这可是我爸爸——最伟大的探险家告诉我的。”闪电抛出麦茜,叉腰道,“现在快跑吧,换我来追你了！”
