氣密性試驗裝置的工作原理是利用气压差来测试产品的密封性能。具体来说，就是用一定压力的气压模拟一定深度的水压来检测产品的防水等级。其工作流程如下：

1、將被測産品放置在測試工裝治具中。

2、通過工廠氣源或增壓泵輸送氣體來增加測試治具腔體內部的壓力。

3、用傳感器檢測測試腔體內部氣壓的變化情況。

4、根據氣壓狀態方程計算出泄漏量是否在設定範圍內，從而判斷産品是否泄漏。

根據檢測方式的不同，氣密性試驗裝置又分爲直壓型氣密儀和差壓型氣密儀。直壓方式檢測相當于用電子天平進行微量稱量，若有一個充滿氣的氣球（相當于被測工件），在電子天平上稱出質量後，若氣球（被測工件）有泄漏則電子天平稱出的質量會減少，這兩次稱量有一質量差，這個質量差就是氣球（被測工件）的泄漏量。若被測容腔有泄漏，則兩次壓力示值有一個差值。只要此差值在允許範圍內，即可認爲被測工件合格。

"Yes, a beautiful story is a thing Ned Ferry loves with a positive passion." In gratitude for Charlotte's word she sank backward in a long obeisance. "May it please your ladyship, dinner is served. Oh, Mr. Smith, I've been listening to Mr. Gholson talking with aunt Martha and Estelle; I don't wonder you and he are friends; I think his ideas of religion are perfectly beautiful!" As she left me, Ned Ferry came out with a sad face, but smiled gladly on me and caught me fondly by the arm. On hearing my brief report he saddened more than ever, and when I said I had promised Jewett he should hand his sword to none but him, "Oh!"--he smiled tenderly--"I don't want to refuse it; go in and hang it at the head of his bed as he would do in his own tent; I'll wait here." "But I thought the' was fi-ive letters," said the Squire as we were about to leave the board; at which Mrs. Wall mumbled to him to "hush up;" for the fifth was to Cécile. The constable laughed gently and stroked his moustache. His theory about the condition of the individual before him slowly developed. "I am not here about that," he said, "at least, not for the present. I am afraid I have some bad news for you. I am speaking to the lady who is known to people generally as Countess Lalage." and declare my principles in my next. to die. There were plenty of strong, willing hands to help carry Si from the caboose to the wagon. It was strange how tender and gentle those strong, rough farmers could be in handling a boy who had been stricken down in defense of his country. Annabel's face was as red as a hollyhock over the way that everybody assumed her right to be next to Si, and those who could not get a chance at helping him helped her to a seat in the wagon alongside of him, while the dethroned Maria took her place by her father, as he gathered the reins in his sure hands and started home. Maria had to expend some of the attentions she meant for Si upon Shorty, who received them with awkward confusion. "Should think they was bride and groom, if they wasn't so old." "'Tention!" commanded Si. "Fall in single rank 'cordin' to your size. Tall boys on the right, short ones on the left, medium in the center. Gid Mackall, you're the tallest. You can go there to the corner o' the platform and let the others form on you." At the word the boys made a rush for the man who was quietly walking off. As they ran they threw stones, which went with astonishing precision and force. One of them struck the man on the head and felled him. Then the boys jumped on him and began pounding and kicking him. Si and Shorty came up, pushed off the boys and pulled the man to his feet. He was terrified at the onset which had been made upon him, and could not understand its reason. "The regiment will go on," reported Orderly-Sergeant, "but Co. Q will stay behind to bury the dead, gather up the arms and things, and then bring up the brigade ammunition train." "Do you know why there isn't?" Dodd's voice was a shock, stronger than before. PUBLIC OPINION SIX Before committing the body to the ground, he said a few words in praise of the dead man. He spoke of his generosity to his neighbours, his kindness to his dependents, his excellences as a husband and a father. "This, brethren, was indeed a man after God's own heart. He lived simply and blamelessly, contented with his lot, and seeking no happiness that did not also mean happiness to those around him. The call of the world"—by which Mr. Barnaby meant Babylonish Rye—"fell unheard on ears attuned to sweet domestic sounds. Ambition could not stir him from the repose of his family circle. Like a patriarch of old, he sat in peace under his vine and his fig-tree...." "Aye, Master," said another, "he is laid up but I fear he has forgot the shrieving. However, he will never again say guilty or not guilty in a jury-box, or kiss the book in justification of bail!" HoME 京香julia与翔太 mide ENTER NUMBET 0015www.kalahari.org.cn
