智能微機量熱儀熱容量標定時的正確操作方法

发布时间：2014-04-24 点击次数：1447次

智能微機量熱儀在做熱容量時是怎麽標定的，是由苯甲酸標定熱容量的，它是指熱量計的量熱系統升高1°c所吸收的熱量，如果在于標定熱容量
完全相同條件，令單位質量煤樣在氧彈中完全燃燒，從而根據內筒水的升溫，就可計算出煤的發熱量。
热容量标定是发热量测定中最为重要的环节，提高可靠的热容量的标定值，是获得准确发热量的前提条件，另一方面，发热量的测定于热容量的标定的操作几乎完全相同。下面就由鹤壁华通分析仪器有限公司为大家简单介绍一下

智能微機量熱儀熱容量標定時的正確操作
3.1 保證有足夠的充氧時間，不得少于15s。當氧氣瓶中壓力降到5.0 MPa以下時，充氧時間應酌量延伸，壓力降到4.0MPa以下時，應更換氧氣;
3.2 要確保點火絲綁好後與接線柱接觸良好，棉線應緊貼苯甲酸表面放置;
3.3 充氧完成後要檢測氧彈是不是漏氣。檢測方法爲：充氧結束後，將氧彈放入裝滿水的大容器中，水面以過氧彈爲宜，看氧彈上有無氣泡冒出，若無即可判定氧彈不漏氣。可進行下一步試驗;
3.4 氧彈放入內桶前要用專用毛巾擦幹淨，防止桌面上的點火絲等雜物帶入內桶，構成內桶出水口堵塞;
3.5 放入氧彈後，輕輕的蓋上內桶蓋子，進入試驗。

煤炭熱值化驗設備常用的有：微機全自動智能微機量熱儀、數顯鼓風幹燥箱、密封式化驗制樣粉碎機、錘式破碎機、天平">電子天平等儀器，鶴壁華通分析儀器有限公司專注研制煤炭化驗設備，免費培訓實驗員，免費保修一年。

The great ship steamed onward, day after day and night after night. There was no storm to break the monotony; no sail showed itself on the horizon; no one left the steamer, and no new-comers appeared; nobody saw fit to quarrel with any one else; and there was not a passenger who showed a disposition to quarrel with his surroundings. Stories were told and songs were sung, to while away the time; and, finally, on the twentieth day, the captain announced that they were approaching land, and the voyage would soon be over. "I could go on with a long account of the tortures in China, but they are not very pleasant reading, and, besides, some of them are too horrible for belief. I will stop with the torture known as 'the hot-water snake,' which consists of a coil of thin tubing of tin or pewter in the form of a serpent. One of these coils is twisted around each arm of the victim, and another around his body, in such a way that the head of the snake is higher than any other part. Then they pour boiling water into the mouth of the snake, and the flesh of the prisoner is burned and scalded in the most terrible manner. This punishment is said to be used rarely, and only[Pg 374] on persons accused of crimes against the government. It is too horrible to be popular, even among the most cold-blooded people in the world. "No, Lieutenant, she nearly cried. Oh, I wish we were on some dangerous errand to-night, instead of just camp and bed!" One glance at the dim mirror and Leona Lalage flew down the corridor. The music of the band was like the sound of mocking demons in her ears. As she flew up the stairs she could see the blank windows of the Corner House staring dreadfully in. Then she locked the door behind her and flung herself headlong down on the bed. . . . Surely they were a long time getting that hot water. In such a case as this hurry was everything. Bruce crept from the room and looked over the banisters. The whole place was in darkness! "Just a moment," Leona said eagerly. "Suppose I deny that. How are you going to prove that I did so?" It was weary work sitting there and pretending to drink, but patience has its reward at last. Gradually the shy swindlers became accustomed to the seedy shop assistant, who even went out of his way to give them hints as to credulous firms. It seemed to Prout that he knew all the gang at last save one. 162 "I told you to go," she repeated, raising her brows. "Come here, Shorty, you dirty little rascal," said the Deacon, assuming a severely maternal tone, at which Si laughed feebly but cheerily, "and let me wash your face and comb your hair." a-courtin', as you will know if ever you was a widower, and he "Could the gunner knock a man's head off, or one of his legs, just as he pleased?" "But—" "You can't go by yourself—he wudn't like it." "Not if we stick to the farm. Did you notice that ring on his little finger?" "Can't you mortgage?"
