幾種常見家用暖氣片常識分享

對于暖氣片，很多來到北方求學的南方學生都是第一次親眼見到，往往會不明所以，心生奇怪。下面我們就對幾種常見的家用暖氣片分別進行講解，希望能對初次接觸暖氣片的人有所幫助。

鑄鐵暖氣片

鑄鐵暖氣片价格便宜，热惰性好、机械强度大、耐腐蚀、使用寿命长，但是由于生产制造不环保，目前国家已经不再提倡使用，很少有家庭安装鑄鐵暖氣片了。

鋼制暖氣片

鋼制暖氣片主要是从欧洲引入的生产技术，对制作工艺要求比较高，具有金属强度高、耐压能力强、外型美观整洁、安装维修方便、散热效率强等优点。在水温低的情况下，鋼制暖氣片照常能散出热来，是目前市场上应用十分广泛的暖气片种类之一。

鋁制暖氣片

鋁制暖氣片具有升温迅速、外型美观、节能节材，不受小区采暖系统的限制等优点。若发现室内温度不够，还可以在采暖季之后加装鋁制暖氣片。但铝材料怕碱水腐蚀，进行内防腐处理可提高使用寿命。

銅鋁複合暖氣片

銅鋁複合暖氣片比较适用范围广泛，具有耐酸腐蚀、轻便灵活的特点，比较适合在独立供暖系统中与燃气壁挂炉等独立供暖设备配合采用。与其它材质的暖气片相比，銅鋁複合暖氣片要用到相对稀少的铜材料，因此价格相对较贵。

暖气片种类主要有以上四种，对家庭用户来说什么材质的暖气片好，圣蒂罗澜建议用户选择鋼制暖氣片和銅鋁複合暖氣片。这两种暖气片比较适合家用，根据圣蒂罗澜市场调查和十多年的售后跟踪服务来看，使用效果非常符合广大消费者的生活需求。

Norah brought him over the typed letter. "We walked by the side of our teams or behind the wagons, we slept on the ground at night, we did our own cooking, we washed our knives by sticking them into the ground rapidly a few times, and we washed our plates with sand and wisps of grass. When we stopped, we arranged our wagons in a circle, and thus formed a 'corral,' or yard, where we drove our oxen to yoke them up. And the corral was often very useful as a fort, or camp, for defending ourselves against the Indians. Do you see that little hollow down there?" he asked, pointing to a depression in the ground a short distance to the right of the train. "Well, in that hollow our wagon-train was kept three days and nights by the Indians. Three days and nights they stayed around, and made several attacks. Two of our men were killed and three were wounded by their arrows, and others had narrow escapes. One arrow hit me on the throat, but I was saved by the knot of my neckerchief, and the point only tore the skin a little. Since that time I have always had a fondness for large neckties. I don't know how many of the Indians we killed, as they carried off their dead and wounded, to save them from being scalped. Next to getting the scalps of their enemies, the most important thing with the Indians is to save their own. We had several fights during our journey, but that one was the worst. Once a little party of us were surrounded in a small 'wallow,' and had a tough time to defend ourselves successfully. Luckily for us, the Indians had no fire-arms then, and their bows and arrows were no match for our rifles. Nowadays they are well armed, but there are[Pg 41] not so many of them, and they are not inclined to trouble the railway trains. They used to do a great deal of mischief in the old times, and many a poor fellow has been killed by them." To see the whole of Tokio is a matter of no small moment, as the area of the city is very great. There seems to have been no stint of ground when the place was laid out, and in riding through it you find whole fields and gardens so widely spread that you can readily imagine yourself to be in the rural districts, and are rather surprised when told that you are yet in the city limits. The city is divided into two unequal portions by the Sumida River, and over this river is the Nihon Bashi, or Nihon Bridge, which is often called the centre of Japan, for the reason that all the roads were formerly measured from it. It has the same relation to Japan as the famous "London Stone" has to England, or, rather, as the London Stone had a hundred years ago. "Yes--well--what of him?" As to the manner of cutting out or planing up the lumber for patterns, and the manner of framing them together, it is useless to devote space to the subject here; one hour's practical observation in a pattern-shop, and another hour spent in examining different kinds of patterns, is worth more to the apprentice than a whole volume written to explain how these last-named operations are performed. A pattern, unless finished with paint or opaque varnish, will show the manner in which the wood is disposed in framing the parts together. IV. Do you play golf or hunt or ride horseback or just sit in the sun “She did take the string, as the letter says,” Jeff nodded. “It was a secret—they didn’t broadcast it that the necklace was in the captain’s cabin, locked up in his safe. Nobody knew it, not even the lady’s personal maid, as far as anybody supposed.” He knew the answer to the puzzle of the missing emeralds! “Now we’ll shelve this mystery.” Mr. Everdail led the way to the tender which would transfer them to the yacht for the evening run around illuminated Manhattan. “Eat, and have a good time, Sky Patrol.” Forbes explained their early return, and spoke of the ranch. "It might be a garden, this territory, if[Pg 315] only it had water enough," he said; "it has a future, possibly, but its present is just a little dismal, I think. Are you greatly attached to the life here, Mrs. Cairness?" He was studying her, and she knew it, though his glance swept the outlook comprehensively, and she was watching the mail-carrier riding toward them along the road. It was the brother of the little girl who followed along behind them, and who ran off now to meet him, calling and waving her hand. "Oh, well, if you d?an't choose to tell me ... But I've eyes in my head." "We won't tell him that, though, Davy—we'll make out as it's pure patriotic feeling on our part." "Either you fetch him here or I send fur the police." Calverley made no reply; but, without looking either at Holgrave, or the man who had so fiercely and tauntingly addressed him, took the advantage offered—passed through the door of the foundry, and through the yielding ranks of sneerers and jibers outside; and mounting his horse, galloped rapidly away from the scene of his defeat, with the shout of a hue and cry following his track as far as the foresters considered their legitimate domain.
