  Development and application of streakline visualization in hypervelocity flows

  摘要：

  A method for visualizing streaklines in hypervelocity flows has been developed. The method uses the high temperatures produced in hypervelocity flows to ablate small amounts of sodium deposited onto a wire stretched across the flow and to broaden the lines in the sodium spectrum. By using a dye laser, tuned to a wavelength close to one of the sodium D-lines, as the light source in shadowgraph or Schlieren visualization, streaklines seeded with sodium become visible through absorption and/or enhanced refractivity. The technique has been used to investigate the stability of the shear layer produced by the curved bow shock on a cylindrically blunted wedge. The results suggest that the shear layer is unstable, exhibiting structures with a wavelength that is comparable to half the nose radius of the body.

  The Rearrangement of Tropones to Dihydrobenzene Derivatives

  摘要：

  光谱数据阐明了 1-苯基环己二烯-1,2-二羧酸中双键的位置，该双键是之前通过 2-苯基托品酮-7-羧酸的碱性重排得到的。还观察到托品酮衍生物与二氢苯衍生物发生了类似的重排反应。托品酮-2-羧酸可生成 2,5-环己二烯-1,2-二羧酸，而 2-苯基托品酮-5-羧酸可生成 1-苯基-2,4-环己二烯-1,4-二羧酸。2-phenyltropone 还能通过碱重新排列为 2-苯基-2,5-环己二烯-1-羧酸。

  Complexation of cyclohexadienes with Fe(CO)3 as the entering group are subject to classical steric hindrance by alkyl groups, but CO2R and related groups introduce a competing factor because they favour sterically the entering group, probably through an intermediate complex. Increase of π-electron availability in the initial 1,4-diene by the attachment of OMe reduces this influence, probably because

  环己二烯与Fe（CO）3作为进入基团的络合会受到烷基的经典空间位阻，但是CO 2 R和相关基团引入了竞争因素，因为它们在空间上更倾向于进入基团，可能是通过中间配合物。通过OMe的连接增加初始1,4-二烯中π电子的利用率可减少这种影响，这可能是因为它有利于直接烯烃络合。非极性条件增加了CO 2的导向作用R，但是除非通过额外的烷基取代，否则无法实现完全的立体特异性。然而，许多立体异构体对可以分开，并且该路线导致许多空间确定的产物的前体，否则它们不易获得。
