连续快速灰分測定儀操作步骤

1、接好電源線和熱電偶線，檢查熱電偶是否插好。

2、打開连续快速灰分測定儀加熱開關，加熱指示燈亮，爐體開始加熱。

3、設定工作溫度：將測量/設定選擇開關置于“設定”處，旋轉溫度設定調節旋紐，使顯示器上顯示的預定溫度爲815℃。再將測量/設定選擇開關置于“測量”處，此時，顯示器上顯示的是爐膛內的實際溫度。

4、當爐膛內溫度達到815℃時，調節儀上的紅燈亮，爐體自動斷電，加熱停止。

5、打開连续快速灰分測定儀电机开关，运行指示灯亮，电机开始运行。如需调整链条的运行速度，应将电机电压先调到最大，然后向低电压调，使电机运行速度达到所需要值。

6、檢查鏈條是否偏離軌道，運轉時是否有打滑或傾斜現象。通過調整支架兩側的調整螺釘，可以改變鏈條的松緊程度和平整度。

7、稱取樣品，並將裝有樣品的灰皿放在鏈條進口處，可並排放置兩個灰皿，且可連續放置。

8、試驗結束，應先關閉加熱開關，停止對爐體加熱。電機連續運行半小時後關閉電機運行開關，關閉總電源。

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?"
