一、制樣

1. 先把提取的爐渣（煤矸石）進行縮分，樣品顆粒3~6毫米

2. 把缩分好的炉渣（煤矸石）样放入制樣机内运行一分钟，取出制好的炉渣（煤矸石）样，放入存样瓶中备用样品颗粒200克

二、稱量

1. 使用万分之一电子天平稱量校验后，称取1克煤樣,並專用包紙包上.

2. 捏團，放在石英坩埚內

三、標定包紙熱

1. 把承載包紙的石英管過放在氧彈內架上

2. 接好點火絲點火棉線

3. 充入98%的氧氣，充氧時間爲25秒，充氧壓力爲2.8-3.0兆帕

4. 把氧彈放入量熱儀中，按測定程序操作

5. 15分鍾後機器自動打印出包紙熱量數值

6. 連續操作4次，並算出4次包紙熱量的平均值，輸入到機器內。

四、測定爐渣（煤矸石）熱量

1. 將備用爐渣（煤矸石）樣拿出。

2. 在電子天平上取一張包紙並記錄包紙重量

3. 在包紙上稱取一克爐渣（煤矸石）（煤矸石）料，記錄樣重

4. 用包紙把爐渣（煤矸石）料卷包起來

5. 用點火棉線把卷包好的爐渣（煤矸石）料系上點火絲，放入石英坩埚上

6. 將准備好的石英坩埚放到氧彈內架上

7. 充入98%的氧氣，充氧時間25秒，充氧壓力2.8-3.0兆帕

8. 把氧彈放入量熱儀中，按測定程序操作

9. 15分鍾後機器自動打印出爐渣（煤矸石）樣引發煤的低位發熱量，及單桶發熱量，按計算鍵可以自動打印出高位發熱量和

實驗結束，得出爐渣的發熱量。

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 001017jz8.com.cn
