发布时间：2014-06-24 点击次数：1468次

(1)電解池要保持清潔、氣密。在儀器安裝、使用和維修過程中，不能用手觸摸電極。
(2)電解池使用一段時間後或在電解池中，底部或邊緣産生汙迹時，要進行清洗--取下電解池蓋，關閉放液口，取出攪拌子；加入洗液至淹沒汙迹，或反複倒斜池體，使洗液反複接觸汙迹，直至汙迹除去，然後用水洗淨池體。
(3)鉑電極片清洗：電解極片不幹淨或有汙垢時，及時用棉球酒精擦洗；指示電極片汙染，可以用酒精燈的氧化焰灼燒電極鉑片，切勿燒玻璃部分，或將電極鉑片浸入洗液中清洗。
(4)玻璃熔板過濾器清洗：熔板出現黑色沈積物時，可先在池體中加入少量水（不淹過熔板），用滴管從熔板的支管中注入少量洗液並使之浸遍熔板，待洗液流盡後，再加入洗液，直至黑色物除盡，熔板潔白如初。
(5)電解液的制備和更換：在更換電解液時，不要把電解液灑到其他物品上，以防腐蝕；如灑上，則一定要用乙醇或丙酮擦洗幹淨。
(6)電解液的加入和放出：加液時，將電解池的放水管捕人盛有電解液的容器中，開戶電磁泵，便能將電解液自動吸人電解池中，然後用止水央爽住放水管即可；也可以直接打開電解池上蓋裝入電解液。放液時，將放水管止水夾松開，便可放出電解池的電解液，放完之後用止水夾再將放水管夾好。

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 00101855.org.cn
