惡臭指一切刺激嗅覺器官使人産生不愉快並損害生活環境的氣體物質。惡臭濃度是空氣質量的一個綜合表征因子，其數值是對混合空氣質量的一種綜合反映。惡臭的來源很多，惡臭的成分也很複雜，需要用一個綜合指標來進行限制，而我國的惡臭限制方法是按照國家《惡臭汙染物排放標准》和（GB14554-93）的規定進行的，廠界環境惡臭濃度的限定值爲200U。

我國作爲世界養豬大國，養豬業在整個畜牧業中占主導地位，養豬業已成爲我國經濟中十分重要的支柱産業之一。據統計，中國養豬業産業化、規模化水平不高，年出欄500頭以上規模豬場不到一半，普通老百姓吃的豬肉一半來自年出欄500頭以下散養農戶、小型養殖場。但是傳統的養殖方式不僅生産效率低，目汙染治理以及惡臭排放等方面也存在著較大的問題。

近年來由于惡臭排放導致居民和企業間沖突日益加劇，居民上訪現象越來越頻繁。環保整治尤其是惡臭整治已經成爲一項事關社會穩定和諧的大事。而惡臭排放的時效性與不確定性也使得環保部門取證難、執法難，因此迫切需要建立實時、高效的，快捷惡臭自動監控系統對惡臭情況進行全天候監控。

汙染源惡臭自動在線監測系統的建设不仅可以解决目前监测采用人工采样和送样到实验室分析费工费时的问题、样品捕获率较低，分析费时费力，数据上报速度慢，信息量少，无法及时反应污染源臭气污染变化现状及规律，并且通过对具有国际先进技术水平的恶臭自动监测系统的介绍，其能够有效推动我区环境管理水平提升，为科学制定环保法规和城市规划提供了准确可靠的数据。

恶臭监测目前采用国家标准分析方法“三点式比较式摺袋法，（GB/T14675-93）”.它是基干人所依赖的觉感官生产实验，采样和分析过程全靠手工操作，导致检测人员工作量及其大，嗅辨别分析时对检测人员限制性条件大，其存在工作效率低下，时效性差，数据客观性差，人工成本高的一系列问题。所以建设汙染源惡臭自動在線監測系統已势在必行。

While they were discussing him, he returned suddenly and said: "And what is sa-kee, please?" "Life is strife indeed to her," I said. Both thanked me and buckled on their belongings, but Ferry's look was peculiarly intelligent; "I was in the small parlor, looking for you," he said; "I thought you would be near the music." And so he had seen Gholson with his revolver on him, and must have understood it! Bruce kissed her behind the demure corner of a Japanese screen. His eyes were dancing with mischief and pleasure. However large the crowd, it was silent as death when the priest Jacobs addressed them. He spoke words of encouragement, hope, and confidence, and urged them to send up their prayers to God Almighty—prayers for peace. When he had ended, these thousands sang the "Hymn to Mary," in18 such perfect order as if only one superhuman body sent forth an immensely powerful sound from earth to Heaven. collars and the material for a new blouse and a jar of violet cream Accession of George II.—Characters of the King and Queen—Adroit Tactics of Walpole—Rise and Fall of Compton—Attitude of the Opposition—Congress of Soissons—Causes of Dispute with Spain—Stanhope's successful Negotiations with King Philip—Retirement of Townshend—Walpole Supreme—Peace Abroad and at Home—Walpole's System of Wholesale Bribery and Corruption—The Public Prisons—Duel between Pulteney and Lord Hervey—The Excise Scheme—Great Outcry—Withdrawal of the Bill—Walpole's Vengeance—Attack on the Septennial Act—Wyndham's Speech—Depression of the Opposition—Definitive Peace of Vienna—Gin Act—The Porteous Riots—The Prince of Wales and the Opposition—Application for an Increase of his Allowance—Birth of George III.—Death of Queen Caroline—Attempt to Reduce the Army—Disputes with Spain—"Jenkins' Ear"—Walpole's Negotiations—Secession of the Opposition—Further Difficulties with Spain—Declaration of War—Privateers and Reprisals—Vernon's Victory—Frederick invades Silesia—Assistance of England—Parliament Meets—Sandys' Motion—Walpole's Defence—Disasters of Maria Theresa—She throws herself on the Magyars—Misfortunes of the English Fleets—Vernon Repulsed from Carthagena—Power slips from the Hands of Walpole—His Last Battles—The Chippenham Election Petition—His Fall. "I say, tell that engineer to uncouple his engine and bring it back up here where the head-light'll cover the other side," said Shorty.
