秋季更換家用暖氣片的注意事項

聖蒂羅瀾散熱器建议，如果所居住的小区为分户供暖，市场上的散热器基本都可选用。

若爲集中供暖，則需根據小區的水質來做選擇，比如，水質含堿量高就不宜采用鋼鋁散熱器，宜選用鋼制散熱器。

而水中含氧量較大，就不宜選用鋼制的，宜選用內層做過防腐處理的鋼制散熱器或者是鋁質散熱器等。

聖蒂羅瀾散熱器一般情况下铜铝复合散热器和新型铸铁的对水质要求不严。另外，各个房间所用散热器材质最好是相同或相近的，以避免由于不同材质之间产生电化学反应而腐蚀。

新型采暖散熱器，按材料的不同分爲鋼制散熱器、鋁合金散熱器、銅制散熱器、銅鋁複合散熱器、鋼鋁複合散熱器、不鏽鋼散熱器等;按産品外形特點又分爲鋼制柱式散熱器(二柱、三柱、四柱)、排管式散熱器(單排管、雙排管)、翼片式散熱器(雙面翼片、單面翼片)、翅片式散熱器(環形翅片、方形翅片)，按散熱方式分爲輻射散熱器、對流式散熱器等。常用的新型采暖散熱器是鋼制柱式散熱器、鋼制排管散熱器、鋁合金柱翼型散熱器、銅鋁複合柱翼型散熱器。

聖蒂羅瀾散熱器材料自身的特性，铝合金耐酸、耐氧化，但易发生碱性腐蚀;钢的强度高，能耐一定的碱性，但易发生氧化腐蚀;铜的耐腐蚀等综合性能较好，但水中硫化物过多或是杂铜也会腐蚀，且铜的机械强度偏低。国家要求铝合金散热器和壁厚在2.5mm以下的钢制散热器，必须进行内防腐处理，涂布内防腐涂层，且铝合金散热器必须采用专用非金属或双金属复合管件，不得使铝制螺纹直接与钢管连接，防止电化学腐蚀。

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.
