論文摘要是對論文的簡短陳述；它具有不讀原文就知全文，短、精、完整三大特點。它一般在全文完成之后形成；論文摘要由目的、方法、結(jié)果和結(jié)論四部分組成；以供讀者確定無誤的閱讀全文。論文摘要翻譯主要語種比較廣泛，有英語翻譯，韓語翻譯，法語翻譯，日語翻譯，德語翻譯，俄語翻譯，阿拉伯語等60多種語言，不過最主要的還是英文翻譯 。
    論文摘要的英文翻譯分為兩大類：
    指示性摘要：只通報論文主題，不介紹研究的材料、方法和結(jié)果，用一般現(xiàn)在時表述。
    資料性摘要：告訴讀者研究的總體情況，使他們了解研究的目的、材料、方法、結(jié)果、結(jié)論以及存在的問題。
    英信翻譯總結(jié)出，論文摘要翻譯無論何種形式的陳述，都包含主題、目的、方法、材料、結(jié)果、結(jié)論這幾點基本要素。 One subsystem critical to the performance of a precision electro-optical line-of-sight (LOS) pointing system is a wide-band inertial stabilization reference. This paper compares, in terms of relative performance of LOS stabilization in the presence of vehicle jitter, three inertial LOS stabilization reference mechanizations for space-based optical systems. The three mechanizations are: an inertially stabilized platform, the Inertial Pseudo-Star Reference Unit (IPSRU) under development at Draper Laboratory; a device called the Optical Reference Gyro (ORG), also developed at Draper Laboratory; and a strapdown wide-band inertial sensor assembly. Each of the three stabilization reference mechanizations generates a collimated alignment beam that is injected into the entrance aperture of the optical system.
    對于電-光視軸（LOS）瞄準(zhǔn)系統(tǒng)精度性能而言，寬頻帶慣性穩(wěn)定參考是一個至關(guān)重要的子系統(tǒng)。本論文從存在飛行器抖動情況下LOS穩(wěn)定的相對性能方面，比較了天基光學(xué)系統(tǒng)三種慣性LOS穩(wěn)定參考機械化。這三種機械化分別為：由德雷帕實驗室開發(fā)的一種慣性穩(wěn)定平臺，即慣性偽星參考裝置（IPSRU）；同樣由德雷帕實驗室開發(fā)的光學(xué)參考陀螺儀（ORG）設(shè)備；以及捷聯(lián)寬頻帶慣性傳感器組件。這三種穩(wěn)定參考機械均能生成注入光學(xué)系統(tǒng)入口孔徑的準(zhǔn)直校準(zhǔn)光束。
    In the stabilized platform mechanization, the alignment beam emanates from a platform inertially stabilized from vehicle jitter in two axes, and thus the alignment beam becomes a jitter-stabilized pseudo-star. An alignment loop closed around the pseudo-star image and a steering mirror in the optical path stabilizes the LOS against vehicle jitter. The ORG alignment beam projects from the gyro rotor, which is decoupled from case motion and is effectively inertially stabilized. The ORG spin-speed noise is compensated with phase-lock technology. In the strapdown mechanization, the alignment beam source is hard-mounted to the vehicle. Inertial measurement of the local vehicle motion is fed forward, open loop, to a steering mirror in the optical path to compensate for alignment beam jitter.
