一、通信管內壁靜摩察系數廠家産品簡介：
是測量通信管內壁靜摩察系數而設計和生産的，具有用性廣、測量精度高、測量安全及可靠性好等特點。符合中華人民共和國交通行業標准JT/T496-2004《公路地下通信管道高密度聚乙烯矽芯塑料管》相關技術標准的要求。技術標准的要求。

二、通信管內壁靜摩察系數廠家技術參數：
?測量範圍：0°～45°
?测量精度： 2.0′
?試棒重量：270±10g
?表層材料邵氏硬度：HD59±3
?表面粗糙度R a 值：0.20μm～0.50μm
?外形尺寸：600X750X1200mm
? 重量:150kg

三、操作步驟：
? 将试样固定在V型铁上，从右端插入试棒使一端露出20mm，拴好链绳。
? 轻微摇动手轮使V型铁上水平泡处于水平位置。
? 打开角度尺紧固栓，转动角度尺使角度尺与副尺归零，拧紧紧固栓。
? 顺时针摇动手轮，使V型铁缓慢倾斜，直至试棒滑动为止。
? 记录下角度尺示值。
? 逆时针摇动手轮，使V型铁水平为止。
? 将试棒拉出通信管外露20mm。
? 按照以上操作步骤连续9次，计算出9次平均值。（倾斜角度≤14°4′依据JT/T683-2009《通信管道静摩擦系数测量仪》之规定要求）

THE GOD OF THE KITCHEN. THE GOD OF THE KITCHEN. It's like farming. You can have extensive farming and intensive I can read your secretary's letter now: And at this day the high road passes Secundra Bagh in ruins, and on the ground where Nana Sahib's soldiers fell, huge flowers are strewn of "flame of the forest" fading into hues of blood. The stranger had a pleasant, round face, with eyes that twinkled in spite of the creases around them that showed worry. No wonder he was worried, Sandy thought: having deserted the craft they had foiled in its attempt to get the gems, the man had returned from some short foray to discover his craft replaced by another. “All right, buddy,” admonished Jeff. “Stick to your job. Sandy or Dick will read the dots and dashes—if he’s using Morse code——” In Europe, Pitt was still bent on those attacks on the coast of France which long experience had shown were of little use as means of successful war, but highly objectionable, as fraught with excessive inhumanity to the innocent people of the seaboard. This, his second expedition, was aimed at St. Malo. A fleet of eighteen ships of the line, thirteen frigates, with sloops, fire-ships, and bomb-ketches, was put under the command of Lord Howe; but as Sir Edward Hawke, his senior, struck his flag, and refused to serve as second, Lord Anson, to get rid of the difficulty, put himself nominally at the head of the squadron. The command of the troops was given to the Duke of Marlborough, a brave man, but destitute of the genius of his father, and Lord George Sackville and Lord Granby were under him. There were fourteen thousand troops of the line and six thousand marines. With these went a number of aristocratic volunteers, amongst them Lord Downe, Sir John Armitage, and Sir John Lowther, the possessor of fourteen thousand pounds a-year. On the 5th of June, 1758, the transports anchored in Cancale Bay, and next day the troops were landed and led against St. Malo. This town, built on one of a cluster of granite rocks which rise out of the sea on that iron-bound coast, they found too strongly fortified to storm, but they burnt a hundred and thirty privateers and a great quantity of small craft in the harbour, and then returned to their ships. They then sailed for Le Havre, but were prevented by the wind from doing the same damage, and so continued their voyage to Granville and Cherbourg, whence they were driven by storm; and thereupon coasting a considerable way farther, but to no purpose, the fleet returned to Portsmouth, the main result being a heavy expense. Fox and the Opposition in the Commons called it breaking windows with guineas; and the old king, who had expressed his dislike of this sort of warfare, said we should brag of having burnt the French ships, and the French of having driven us away. When the boys were properly washed and combed, Mrs. Klegg, her kind, motherly face beaming with consciousness of good and acceptable service, would enter with a large tray, laden with fragrant coffee, delicious cream, golden butter, her own peerless bread and bits of daintily-broiled chicken. "Open it and read it, Maria," said Si, to whom reading of letters meant labor, and he was yet too weak for work. "Come, now, be reasonable," pleaded Bob. "Why can't you and I go along together and run the thing? We'll pull together all right. You know I've been a Sergeant for a long time, and know all about the handling of men." "No, no; give him a show for his life," answered Shorty, laying his hand on Pete's gun. "That old-time religion." HoME 销售台湾食品是否要换中文标签ENTER NUMBET 0019www.27129.com.cn
