測硫儀（定硫儀）的分析原理

发布时间：2012-09-14 点击次数：1244次

煤中的含硫量是評價煤炭質量重要的指標，也是對大氣汙染的主要成份之一。煤炭生産部門和化肥、發電、民用、煉焦和建材等部門都非常重視在所用煤中對全硫含量的分析。

主要分析原理：

煤样在1150度的高温条件下，在净化过的空气流中燃烧，煤中的各种形态的硫被燃烧分解出来，被空气流带到电解池内与水化合成了H₂SO₃，由于其破壞了電解池內的原有碘—碘離子對的動態平衡，便儀器立即輸出電流電解碘化鉀溶液而生成碘，恢複原來的動態平衡，這也就是GB/T214—1996中的庫侖滴定。其具體恢複到原的動態平衡時所消耗了多少電流，這是與煤樣中燃燒分解出硫的多少有直接的關系。它可由微機處理器測量並計算出，這樣就可以得出煤中的全硫的含量。

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?" HoME 色色新妈妈电影 ENTER NUMBET 001051qihuo.org.cn
