发布时间：2012-05-26 点击次数：1849次

快速灰化法

1、快速灰分測定儀法

(1)方法及要點。

将装有煤样的灰皿放在预先加热到（815±10）℃的灰分快速测定仪的传送带上，煤样自动送入仪器内完全灰化送出。称重带灰灰皿，以残残留的质量质量占煤样质量的百分数作为灰分的分产率。

(2)測定步驟

将快速灰分測定儀预先加热至（815±10）℃。开启传送带并将其传送速度调节至17mm/min左右或者其他合适的速度。称取（0.5±0.01）g空气干燥煤样（称准至（0.0002g)，摊平后放在快速灰分測定儀的传送带上，灰皿自动送入炉中。灰皿从炉口送出时，取下并放在耐热瓷板上或石棉板上，在空气中冷却至5min左右后，移入干燥器中冷却至室温后，称重。

2、馬弗爐法

(1)方法與要點

將裝有有煤樣的灰皿由爐外逐漸送入預先加熱至（815±10）℃的馬弗爐中灰化並灼燒到質量恒定，以免殘留物的質量影響點煤樣質量的百分數作爲灰分産率。

(2)測定步驟

馬弗爐升溫到850後，打開爐門，把放有灰皿的耐熱瓷板或石棉板緩慢的推入馬弗爐中，使第一排灰皿中的煤樣灰化。停5—10min之後，煤樣不再冒煙時，以不大于2mm/min速度把二、三、四排灰皿順序推進爐內熾熱部分（注意不能使煤樣爆燃，否則所作的試驗作廢）。關上爐門，在（815±10）℃的溫度下灼燒40min，取出灰皿，放在耐熱瓷板或石棉上，在空氣中5min左右，移入幹燥器中，冷卻至室溫，稱重量。

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 0010balflo.org.cn
