GB/T 17144残炭测定仪的测定方法

发表时间：2020-04-13 17:55作者：得利特

油品的殘炭值，是指油品在特定的高溫條件下，經過蒸發及熱裂解過程後，所形成的炭質殘余物占油品的質量百分數。殘炭值的大小與油品的化學組成及灰分含量有關。除灰分外，油品中的膠質、瀝青質及多環芳烴等物質是殘炭的主要來源。故通常情況下，石油産品殘炭測定值可用來表征油品的相對生焦傾向的大小（含有生灰添加劑的油品除外），用于指導原料的選擇及油品的生産工藝。康氏法是世界各國普遍采用的一種標准方法；微量法是近些年國內外普遍采用的一種簡便而高效的殘炭測定方法，我國于1997年正式列爲國家標准方法；電爐法源于原蘇聯，使用的國家很少；蘭氏法因其殘炭數據與康氏殘炭間只存在近似關系，故較少被采用。鑒于不同殘炭測定方法的工作原理、實驗裝置、操作條件等因素均存在一定差別，利用不同方法得到的測定結果間的相關性如何一直是油品分析工作者關心的問題，

得利特北京科技有限公司推出A1260微量残炭测定仪是按照中华人民共和国标准GB/T 17144《石油産品殘炭測定法》所規定的要求設計制造的，適用于按此標准所規定的方法測定石油産品經蒸發和熱解後留下的殘炭量，以提供石油産品相對生焦傾向的指標。

石油産品殘炭測定主要技术参数及指标：

1、測量範圍：0.0℃～+1372℃

DANGEROUS PLACE ON THE SUWO NADA. DANGEROUS PLACE ON THE SUWO NADA. "Richard, it helps the wrong way; I know that story. After hearing that story she is, yes! the one woman of all women to send me this." Another day arose. A courier brought passes for our three or four other wounded to go home as soon as they were fit to travel, and by night they were all gone. At early bedtime came two surgeons of high rank all the way from Johnston's army up in Mississippi. General Austin had asked this favor by telegraph. Harry had been gone thirty-six hours, and Ferry was just asking if he had not yet got back, when the surgeons came in to the room. A pleasantry or two consumed a few moments. Then the surgeon in charge of us told of a symptom or two, to which they responded only "hmm," and began the examination. Miss Harper sent her three nieces away. I lay and listened in the busy stillness. Presently one of the examiners murmured with a certain positiveness to the other, who after a moment's silence replied with conviction; Miss Harper touched our surgeon's arm inquiringly and he looked back in a glad way and nodded. Miss Harper nodded to me; they had located the ball! Now the conversation turned upon men and events of the day, while one of the visitors, with his back to the patient, opened a case of glittering knives. Presently the professional heads came so close together as quite to hide the patient; they spoke once or twice in a manly soothing tone. Miss Harper stroked my temples to keep me down, one of the busy ones spoke again, and lo! the thing was done, there was the ball in the basin. As the men of blood sped through their kind after-work the news flew to and fro; Camille wept,--since she could not hurrah,--Cécile told Charlotte, the heavenly-minded Estelle was confirmed in her faith, Miss Harper's black eyes, after a brief overflow, were keener and kindlier than ever, and as the surgeons spoke the word "done," Ferry asked again if Harry had not got back yet. Pretty soon Harry did arrive, with news of great feats by our cavalry against our old enemy Grierson, in which Austin's brigade had covered themselves with glory, and in which he had had his own share; his hand was swelled as big as his heart. In all the Confederacy no houseful went to sleep that night in sweeter content. I sank into perfect bliss planning a double wedding. "Well, I can name several! I don't call Scott Gholson anybody, but there's Major Harper--No, I'm not talking too loud, Ned isn't hearing a word. Major Harper's so hot against this thing that he brought it up, with me, yesterday on the battlefield." Mrs. Flack held the greater part of herself in a semicircle of red arm. "You are a one," she declared. Then she looked at Mr. Flack, who sat unmoved. "Why don't you laugh. It would do you good. You take everything so serious." "Certainly, captain." The final defeat of polytheism proved, in some respects, an advantage to Neo-Platonism, by compelling it to exchange theological controversy for studies which could be prosecuted, at least for a time, without giving umbrage to the dominant religion. At Alexandria the new spiritualism was associated, on genuinely Platonic principles, with the teaching of geometry by the noble and ill-fated Hypatia. In all the Neo-Platonic schools, whether at Rome, at Alexandria, at Constantinople, or at Athens, the writings of Plato and Aristotle were attentively studied, and made the subject of numerous commentaries, many of which are still extant. This return to the two great masters of idealism was, as we have already said, the most valuable result of the metaphysical revival, and probably contributed more than any other cause to the preservation of their works amidst the general wreck of ancient philosophical literature. Finally, efforts were made to present the doctrine of Plotinus under a more popular or a more scientific form, and to develope it into systematic completeness. [Pg 50] Beyond the "deadening" came a horde of pursuing rebels, firing and yelling like demons. The sight and sound swelled the boys' hearts with the rage of battle. "Why, what in the world have I got on that's military?" asked Billings, looking himself over. "Stephen, you were not used to answer me thus. I charge you, by the authority and love of thy mother, and in the name of the blessed saints, to tell me what has happened." HoME 飞鹰伦理影院ENTER NUMBET 004yijiajz.com.cn
