The Duke of Medina Sidonia now sent a message to the Duke of Parma in Dunkirk:"I am anchored here two leagues from Calais with the enemy's fleet on my flank. They can cannonade me whenever they like, and I shall be unable to do them much harm in return." He asked Parma to send fifty ships to help him break out of Calais. Parma was unable to help as he had less than twenty ships and most of those were not yet ready to sail.That night Medina Sidonia sent out a warning to his captains that he expected a fire-ship attack. This tactic had been successfully used by Francis Drake in Cadiz in 1587 and the fresh breeze blowing steadily from the English fleet towards Calais, meant the conditions were ideal for such an attack. He warned his captains not to panic and not to head out to the open sea. Medina Sidonia confidently told them that his patrol boats would be able to protect them from any fire-ship attack that took place.Medina Sidonia had rightly calculated what would happen.

1577年，他再次从英国出发，乘着旗舰"金鹿"号直奔美洲沿岸，一路打劫西班牙商船，西班牙人做梦也想不到，竟然有人敢在"自家后院胡闹"，当他们派出军舰追击时，德雷克早已逃往南方，但由于西班牙的封锁，他无法通过狭窄的麦哲伦海峡，在一次猛烈的风暴中，"金鹿"号同船队其它伙伴失散了，被向南吹了5°之多，来到了西班牙人也未曾到过的地方，自从麦哲伦海峡被发现以来人们一直认为海峡以南的火地岛就是传说中的南方大陆的一部分，但此时呈现在德雷克面前的是一片汪洋大海，德雷克被这意外的发现惊呆了，他很高兴的向大家宣布"传说中的南方大陆是不存在的，即使存在，也一定是在南方更寒冷的地方，"(直到今天我们还称这片广阔的水域为"德雷克海峡")，但德雷克却一直向西横渡了太平洋。1579年7月23日，他到达了马里亚纳群岛，8月22日穿过北回归线，9月26日回到了阔别已久的普次茅斯港，再次成为了"民众的英雄"，这次航行是继麦哲伦之后的第二次环球航行，但德雷克却是第一个自始至终指挥环球航行的船长(众所周知，麦哲伦在菲律宾被土人做成三明治吃掉了)。

At the same time, combining with the actual condition of delivery pipeline of our country and some prevalent leak detection and location methods, this paper raised a method, which is based on wavelet analysis and negative- pressure-wave to detect and locate the leakage. Jobs in the paper are as follows:As affected by gas density, pressure, specific heat and pipe material, the velocity of negative-pressure-wave improved depending on the energy conservation. At one time, taking the affection of velocity of gas flow, the location formula was modified in some degree.When locating the leaks with location formula, the iterative approach algorithm was adopted as a new method to increase the location accuracy level of system.Multi-scale decomposition and reconstruction of wavelet transform is utilized to filter the noise of negative-pressure-wave, which was brought by leakage.

The method is to choose a wavelet by regularities of the wavelet and the signal.Finally, a plan, which bases on SCADA system for inspection and detection of natural gas leakage, is proposed in the article.
