Analysis to date has assumed that the atmosphere is calm and fixed -Rarely true since we must contend with gusts and winds -Need to understand how these air motions impact our modeling of the aircraft. Must modify aircraft equations of motion since the aerodynamic forces and moments are functions of the relative motion between the aircraft and the atmosphere, and not of the inertial velocities

1.人民币实行汇率并轨在1994年实际外汇改 革之前,我国基本上实行的是固定汇率制度, 其中还曾有过双轨制汇率时期。 1993年11月14日,党的十四届三中全会通过的 《中共中央关于建设社会主义市场经济体制若 干问题的决定》中要求“改革外汇体制,建立 以市场供求为基础的有管理的浮动汇率制度和 统一规范的外汇市场,逐步使人民币成为可兑 换货币”。根据全会精神

rganometallic compounds are compounds that have a carbon-metal bond; they lie at the place where organic and inorganic chemistry meet. You are already familiar with at least one organometallic compound, sodium acetylide (NaC=CH), which has an ionic bond between carbon and sodium. But just because a compound contains both a metal and carbon isn't enough to classify it as organometal-

ou have already had considerable experience with carbanionic compounds and rgani their applications in synthetic organic chemistry. The first was acetylide ion in Chapter 9, followed in Chapter 14 by organometallic compounds-Grignard reagents, for example-that act as sources of negatively polarized carbon. In Chapter 18 you learned that enolate ions-reactive
