Oxygen

氧(Oxygen),元素符號(hào)O,位于元素周期表第二周期ⅥA族。1774年英國(guó)科學(xué)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(fā)現(xiàn)一種能強(qiáng)烈?guī)椭紵臍怏w。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(gòu)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(zhì)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(gè)功能強(qiáng)大、使用方便且支持各種操作系統(tǒng)和編程語言的代碼文檔生成系統(tǒng)。DOxygen由荷蘭人Dimitri van Heesch.開發(fā),并且在GNU公共許可證(GPL)下發(fā)布,目前已經(jīng)成為各主要的Linux發(fā)行版的附帶組件。眾多重量級(jí)的軟件項(xiàng)目(如KDE,Qt、ACE庫(kù)等)都選用DOxygen作為其編檔工具生成項(xiàng)目文檔。 DOxygen最初在Linux下開發(fā),但已經(jīng)被移植到多個(gè)操作系統(tǒng)平臺(tái)下,包括Unix的各發(fā)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(fēng)格),對(duì)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.
