Spacecraft orbit evasion is an effective method to ensure space safety. In the spacecraft’s orbital plane, the space non-cooperate target with autonomous approaching to the spacecraft may have a dangerous rendezvous. To deal with this problem, an optimal maneuvering strategy based on the relative navigation observability degree is proposed with angles-only measurements. A maneuver evasion relative navigation model in the spacecraft’s orbital plane is constructed and the observability measurement criteria with process noise and measurement noise are defined based on the posterior Cramer-Rao lower bound. Further, the optimal maneuver evasion strategy in spacecraft’s orbital plane based on the observability is proposed. The strategy provides a new idea for spacecraft to evade safety threats autonomously. Compared with the spacecraft evasion problem based on the absolute navigation, more accurate evasion results can be obtained. The simulation indicates that this optimal strategy can weaken the system’s observability and reduce the state estimation accuracy of the non-cooperative target, making it impossible for the non-cooperative target to accurately approach the spacecraft.

2019年美国小说家科尔森·怀特黑德以作品《镍币男孩》再次获得普利策奖,成为美国历史上第四位两获普利策奖的小说家。怀特黑德自上世纪九十年代开始文学创作,恰逢新现实主义获得学界高度关注和热烈讨论的时期,因此其创作或多或少受其影响。新现实主义继承了传统现实主义真实再现社会现实的主题以反映当代人的生存困境,舍弃其固定单一的叙事手法,取而代之的是丰富多变的后现代主义的叙事技巧,以贴合当代读者阅读和审美需求。《镍币男孩》具有鲜明的新现实主义特征,作者在真实再现吉姆克劳时代美国南部历史现实的同时引导更多读者将目光转移到当代社会以关注在美愈演愈烈的种族矛盾和暴力问题。目前,批评界虽然注意到该作的新现实主义特征,分别对该作品的内容或是叙事做出了初步分析,但是仍未结合内容创作和叙事技巧分析该作。本文作者认为,对新现实主义作品的批评研究而言,这两者缺一不可,因此本篇论文将结合这两方面从新现实主义的角度对该作进行更为全面分析以此为现有的科尔森·怀特黑德和《镍币男孩》的研究作出补充。本文以新现实主义的角度,从以下三个方面对《镍币男孩》进行研究。在角色塑造上,本文分析了《镍币男孩》中体现的新现实主义小说的典型人物形象,具体以“为实现平等而战的斗士”的埃尔伍德和“仍挣扎于生存的小人物”特纳为主要研究对象。通过完整分析这两类人由启蒙到成熟的人生经历,笔者具体分析吉姆克劳时代在白人统治下的美国社会图景,进而对吉姆克劳乃止当代社会仍普遍存在的问题进行更为深入的剖析。在表现手法上,《镍币男孩》是现实主义和后现代主义的完美融合。笔者具体分析了作者怀特黑德如何使用简洁直白的语言在虚构的作品中再现了一段真实的历史事件,有效地强调了黑人悲惨命运的必然性。同时还将具体分析“间接性和偶然性”等后现代主义特征与现实主义特征的“直接性和必然性”融合在一起所达成的生动阅读效果。事件发生于偶然,但黑人的命运却早已注定,新现实主义的表现手法更加衬托出黑人的宿命感,加深悲剧的氛围,对糟糕的社会现实进行有力的批判。在艺术特征上,怀特黑德融合了多元的后现代叙事技巧,使得行文不再呆板和刻意,创造了新现实主义独特的审美体验。《镍币男孩》双线并织,在交错的时空中,以外部坏境和心理描写的双重叙述视角真实反映了在备受压迫的时代中黑人们的行为和内心挣扎。张弛有度的叙事节奏伴随着参差有致的篇幅形成本作的另一大亮点,节奏由前期的缓慢渐近到中期的紧张,暗示着埃尔伍德的主观意志从被压抑到释放;由前期舒缓的情节描写渐进到后期紧促的心理描写,暗示着黑人们试图摆脱创伤的艰辛过程。张弛有度的叙事节奏由表层痛苦深入到内心创伤,增加了作品的厚重。
