超聲波焊接原理

“超聲波”可以通過什麽進行傳播？

声波频率是一种能够在气体、液体、固态中传播的类型机械波。依据频率，声波频率可分成次声波，声波和超聲波。声波频率在16Hz-20kHz中间，是人耳能够听见的机械波；次声波是频率小于16 Hz的设备，而超聲波是频率高过20kHz的机械波。

超聲波的特點是高頻率，短光波長和繞射狀況小。它最明顯的特性是方向性好，在液體和固態中的衰減系數不大，穿透工作能力大，碰到物質頁面的時候會造成顯著的反射和映射，因而在工業生産上獲得了普遍的運用。

超聲波的传播速率：超聲波一般具备纵波，横波与面波，其传播速率在于物质的延展性参量和相对密度。仅有纵波能够在气体和液体中传播。气体中的声速为342m / s，液体中的声速为900-1900M / s。在固态中，纵波，横波和面波的声速具备一定的关联。一般而言，裁切波速率是竖向波速率的一半，而表面波速率大概是裁切波速率的90％。

當超聲波在物质中传播时，伴随着传播间距的提升，动能慢慢衰减系数。动能的衰减系数在于超聲波的蔓延，透射和消化吸收。

应用超聲波做为检验方式，它能够转化成超聲波并接受超聲波。实行此作用的机器设备是超聲波感应器。

超聲波具备以下特点：
　　1、超聲波可在气体、液态、固态、固溶体等物质中合理散播。
　　2、超聲波可传送较强的动能。
　　3、超聲波会造成反射面、干预、累加和共振原理。
　　4、超聲波在液态物质中散播时，可在页面上造成明显的冲击性和空蚀状况。

‘Oh, yes, you could. Now do just as I tell you, Alice. When you’ve eaten, we’ll talk again.’ "Not a sign of a sign! And yet I'll swear it! Do you know where she's gone?" "Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel." "I am...." “Bad news?” Larry asked, climbing to the turf. Larry braced himself against the slap of the wheels into the surface water. That might offer just enough resistance to nose them in. However, it ended, as soon as Mr. Everdail had sailed on the yacht to join his wife at their lakeside camp in Maine, uncanny light, odd noises and other strange things had become evident again, as an excited local correspondent had notified the paper. Reporters, searching, and watching, had found nothing so far but the public would be informed as soon as they discovered the secret. He believed that he had no ties now, that friendships, the love of woman, and the kiss of children all had missed him, and that his, thenceforth, must be but vain regret. So far as he knew, Felipa had gone away without ever having received his letter. The man he had intrusted it to had been killed in the Aravaypa Ca?on: that he was certain of; and it never entered his head that his papers might have fallen into other hands, and the note have finally been delivered to her. She was leading the sort of life that would most quickly put him entirely out of her mind. He was taking the Washington papers, and he knew. She had gone away, not even sure that he had given her a thought since the night in the Sierra Blanca when Black River had roared through the stillness, and they had been alone in all the wild world. What a weird, mysterious, unearthly scene it had been, quite outside the probabilities of anything he had imagined or contemplated for a single minute. He had never regretted it, though. He believed in impulses, particularly his own. Yet she not only loved Cairness as much as ever, but more. Her church had the strong hold of superstition upon her, but she might have thrown it off, grown reckless of enforced conventions, and have gone to him, had not faithfulness and gratitude held her yet more powerfully. "Yes, that is she; glad to see you back, Missy," said the General, patting the cow on the back. "Take her back and give her a good feed, if you can find it, for probably she's pretty hungry." Have you never heard of AMP burning them, you silly damn fool? Her young face bowed to his neck, and suddenly his lips crept round and lay against the coolness of her cheek. She did not move, and he still walked on, the grass splashing under his feet, the rabbits scampering round him, showing their little cotton-tails in the dark.
