密度測定儀怎麽測量液態石油密度？

发表时间：2020-03-03 00:06作者：得利特

1、密度測定儀在通電前，必須先在浴缸內加好水、油或混合液體。浴缸內未加液體時，切不可通電工作！加熱器切不可在無液體的空氣中使用！

2、密度測定儀使用時應注意安全，接入儀器的電源線應有良好的接地端，相線與接地線不要搞錯，保證儀器外殼與電源線接地端接觸良好。

3、在更換保險絲管或其它電器元器件時，應先切斷電源（保險絲管置于電源插座內），切不可帶電操作。

4、在使用密度測定儀前应注意各接插件接触良好。温度传感器损坏或与机箱未连好，温控仪PV显示窗将无数字显示。

5、溫度傳感器由三線引出接到插頭上，環境溫度20℃時,其中二根插針間電阻爲零,與另一插針間電阻約爲107.79歐姆。

6、密度測定儀出廠時，溫控儀自整定參數已設定好，開機後即自動進入自整定狀態，用戶無須再重新設定。當控溫效果變差時，可參照溫控儀說明書重新整定。

7、保持良好的散熱通風條件。

8、若控溫效果較差時請檢查600W加熱管或控制該加熱管的可控矽。若經檢查或更換確定該加熱管或可控矽完好後，再重新調溫控儀自整定狀態。

9、若攪拌電機不轉，則應檢查電容是否損壞。

注意：當浴缸內加水時，室溫低于0℃時請將浴缸內的水放盡，防止結冰損壞器件！

警告：密度測定儀若出現故障應及時切斷電源，請專業技術人員檢修並排除故障後方可繼續使用，防止發生意外！

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 004greenart888.com.cn
