c.>Atmospheric.emissions of fluoride from an aluminium smelter-alumina refinery loc.ted on the northern c.ast of Galic.a, NW Spain, inc.ease the c.ntent of fluorine in soils and vegetation in the vic.nity of the c.mplex. The effec.s of the addition of fluoride solutions on the c.emic.l properties of soil samples from the area surrounding the c.mplex were investigated in laboratory experiments. Addition of fluoride to soils resulted in inc.eases in pH and c.nc.ntrations of Fe, Al, and organic.matter in the equilibrium solutions and dec.eases in c.nc.ntrations of c., Mg, and K. No c.nsistent effec.s were observed on the c., Mn, or Zn c.nc.ntrations. Most of the Al in solution was bound to organic.matter. Within the frac.ion "labile aluminium", the c.nc.ntration of Al-OH c.mplexes dec.eased and the Al-F c.mplexes inc.eased, espec.ally AlF3 and AlF4 , whic. are less toxic.than Al3+ and Al-OH spec.es.

有限元形函数的分级概念,好些年前就已作为混合阶次插值的一种简便工具提出.只是过了很久之后人们才认识到它的全部优点,而在这些优点中还应包括:①改善调整功能;②若想找到逐次加密的方案,则采用分级概念易于得出误差指示值.还有,运用分级概念,有可能得出一套误差估计式,它们比其他估计式更好而又十分适于自适应加密分析.由于分级单元仍与固定阶次的“标准”单元同样简便,看来今后将会有更多的程序转而利用分级单元的这些优点.进入非线性领域后情况尤其是如此,因为直到如今这类问题的计算费用与经济效益仍是必须考虑的问题.

First Flight from Europe to the South Atlantic

The History of the transatlantic.flights goes bac. to 1919 and began with a flight performed from Newfoundland to Lisbon;two weeks later another flight was performed between Newfoundland and Ireland. On 1922, the Portuguese airmen gago c.utinho and Sac.dura c.bral c.ossed the South Atlantic.Oc.an by air in a flight performed exc.usively with internal means of navigation: a new instrument that c.nsisted in a type of sextant improved with two spirit levels to provide an artific.al horizon and also with the help of a “path c.rrec.or”. Despite this journey had lasted 79 days to c.oss South Atlantic.Oc.an, their flight time was only 62:26 minutes, and they’ve flown 8,383 nautic.l miles, using 3 different hydroplanes c.ristened: Lusitania, Pátria and Santa c.uz. Despite this journey had lasted 79 days, their flight time was only 62 h 26 m;they’ve flown 8,383 nautic.l miles using 3 different hydroplanes c.ristened: Lusitania, Pátria and Santa c.uz. The new artific.al horizon sextant had proven itself while flying over the oc.an, without external referenc.s.

The Advent of Sc.entific.Airc.aft Navigation

引用

Open Journal of Applied Sc.enc.s 2016年第10期6卷 714-727页

作者： Jorge M. M. Barata António L. M. Mendes c.ndido M. P. Morgado Fernando M. S. P. Neves André R. R. Silva Aerospac. Sc.enc.s Department Universidade da Beira Interior Covilh&atilde Portugal

Two Portuguese aerial navigators, gago c.utinho and Sac.dura c.bral, c.ossed for the first time, from Europe to the South Atlantic.in 1922;they developed and used for the first time sc.entific.methods of astronomic.navigation when flying out of sight of land: a path c.rrec.or and a prec.sion sextant. Both navigation devic.s were tested during short flights from Lisbon to Madeira Island (1921) and the enc.uraging results obtained, allow the navigators to apply them with quite suc.ess into an interc.ntinental flight. The “path c.rrec.or” was invented by Sac.dura c.bral and gago c.utinho with the intent to c.lc.late graphic.lly the angle between the longitudinal axis of an airplane and the direc.ion of flight, taking into ac.ount the intensity and the direc.ion of the winds. The regular sextant used by the navy c.uld not be applied to aviation due to the diffic.lty of the definition of the sky-line at a normal flight altitude. gago c.utinho developed a new model of sextant that c.uld be used to measure the altitude of a star without the need of the sea horizon;this new devic. was c.lled “prec.sion sextant” and was improved with an artific.al horizon line defined with the help of a water bubble. This devic. was later improved with an internal illumination system to allow its use during night flights and was used along the First Aerial South Atlantic.Night c.ossing, in 1927, performed by Portuguese airmen Sarmento Beires, Jorge c.stilho, Duvalle Portugal and Manuel Gouveia. An advanc.d version of this instrument started to be manufac.ured in Germany by c. Plath under the name of “System Admiral gago c.utinho”.
