使用量熱儀測定煤炭熱值後，應經常進行下述檢查和維護，可使儀器經常保持良好的工作狀態，同時也能延長量熱儀的使用壽命。
1.量熱筒：試驗結束後應將筒中水排放到外筒，擦幹並保持清潔。

2.氧彈：除每次試驗後對氧彈進行清洗和幹燥外，對以下幾點也應該注意和檢查：
（1）.氧彈只能用手擰動，當手感到有阻力即應停止，切忌用工具硬擰，每天試驗完畢後，應進行一次清洗。
（2）.彈帽和閥座，用完後應沖洗幹淨並擦幹。
（3）.彈杯沖洗幹淨，擦洗螺紋，並檢查彈杯上是否有機械損傷，注意不許將彈杯倒置。
（4）.檢查密封圈是否磨損和燃燒時的損傷，如密封不嚴有漏氣現象，則應更換 .
（5）.檢查絕緣墊和絕緣套是否良好，有無破損，可定期作絕緣性能檢查。
（6）. 定期對氧彈進行 20.0Mpa水壓試驗，每次水壓試驗後，氧彈的使用時間不得超過一年（或不得超過5000次試驗）。

3.試驗用水：最好是純淨水，並且要定期更換，確保試驗可靠性和成功率。
注意：爲了安全使用該系統，計算機設備必須可靠接地。

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 0010www.cmcsoft.cn
