Oxygen

氧(Oxygen),元素符號O,位于元素周期表第二周期ⅥA族。1774年英國科學家約瑟夫·普里斯特利(J.JosephPriestley)用透鏡把太陽光聚焦在氧化汞上,發現一種能強烈幫助燃燒的氣體。安托萬-洛朗·拉瓦錫(Antoine-LaurentdeLavoisier)研究了此種氣體,并正確解釋了這種氣體在燃燒中的作用。氧是地殼中最豐富、分布最廣的元素,也是構成生物界與非生物界最重要的元素,在地殼的含量為48.6%。單質氧在大氣中占20.9%。[1]

  • DOxygen的詞根來源于Document(文檔)和Oxygen(氧氣)

    DOxygen的詞根來源于Document(文檔)和Oxygen(氧氣),它是一個功能強大、使用方便且支持各種操作系統和編程語言的代碼文檔生成系統。DOxygen由荷蘭人Dimitri van Heesch.開發,并且在GNU公共許可證(GPL)下發布,目前已經成為各主要的Linux發行版的附帶組件。眾多重量級的軟件項目(如KDE,Qt、ACE庫等)都選用DOxygen作為其編檔工具生成項目文檔。 DOxygen最初在Linux下開發,但已經被移植到多個操作系統平臺下,包括Unix的各發行版本、MS Windows和Mac OS。DOxygen目前最新的版本是1.3.6,支持的編程語言包括 C++,C,Java,IDL(CORBA和MS風格),對Objective-C, PHP, C#和D語言也有部分支持。

  • A Single-Chip Pulsoximeter Des

    This application report discusses the design of non-invasive optical plethysmographyalso called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). Thepulsoximeter consists of a peripheral probe combined with the MCU displaying theOxygen saturation and pulse rate on a LCD glass. The same sensor is used for bothheart-rate detection and pulsoximetering in this application. The probe is placed on aperipheral point of the body such as a finger tip, ear lobe or the nose. The probeincludes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) andthe other in the infrared spectrum (940nm). The percentage of Oxygen in the body isworked by measuring the intensity from each frequency of light after it transmitsthrough the body and then calculating the ratio between these two intensities.

  • Thin Film Metal-Oxides

     This chapter surveys the high temperature and Oxygen partial pressure behavior of complex oxide heterostructures as determined by in situ synchrotron X-ray methods. We consider both growth and post-growth behavior, emphasizing the observation of structural and interfacial defects relevant to the size-dependent properties seen in these systems.

  • 血氧儀核心硬件電路設計及Multisim仿真

    為了實時檢測血氧量,能使缺氧特別敏感的腦組織或心臟類疾病患者得到及時治療,采用近紅外雙波長透射式光電脈搏血氧測定法,以H橋電路對發射光源進行控制及通用運算放大器搭建濾波電路。運用參數理論計算和計算機仿真結果相對比的方法,通過Mu ltisim軟件對所設計電路進行仿真,仿真結果與理論參數計算相吻合,證明了電路參數設計的可行性,為血氧儀的實物制作提供參考。For real-time detection of Oxygen saturation for timely treatment of the brain or heart,which are very sensitive to Oxygen inadequacy,the near-infrared wavelengths double photoelectric pulse oximeter transmission method is adopted.The illuminant is controlled with the H bridge circuit and the filter circuit is built with general op-amps.Parameters by theoretical calculation is compared with the computer simulation results in Multisim and satisfactory results are obtained.It is shown that the design of the circuit parameters is feasible and can be a help in making the physical blood-Oxygen monitor.
