为了使检测并最大化紧凑型二进制系统引力波观测的物理输出，这至关重要，至关重要。目前的工作旨在概述重力波数据分析中用于紧凑型二元合并的（灵感）波形的非专家。我们首先提供了简单的牛顿轨道动力学和线性重力理论的重力辐射物理学的基本要素，描述了应用于二进制系统的绝热近似：在实践中构建理论引力波形的关键要素。接下来，我们将重力波形在牛顿后的近似值中列为一般相对性，并突出显示了缓慢发展，旋转，旋转，非衰减的，非循环的二进制黑色孔的灵感波形的基本输入，不错，牛顿后的能量，磁通量，磁通量和（吸收校正）平衡。然后在时间和频域中呈现牛顿后的灵感模板。最后，包括合并和后续的响声阶段，我们简要调查了LSC算法库仿真中当前实现的紧凑型二进制合并的完整波形模型的两个家族：有效的一体方法和现象学频率域模型。
To enable detection and maximise the physics output of gravitational wave observations from compact binary systems, it is crucial the availability of accurate waveform models. The present work aims at giving an overview for non-experts of the (inspiral) waveforms used in the gravitational wave data analysis for compact binary coalescence. We first provide the essential elements of gravitational radiation physics within a simple Newtonian orbital dynamics and the linearized gravity theory, describing the adiabatic approximation applied to binary systems: the key element to construct the theoretical gravitational waveforms in practice. We next lay out the gravitational waveforms in the post-Newtonian approximation to General Relativity, and highlight the basic input for the inspiral waveform of the slowly evolving, spinning, nonprecessing, quasicircular binary black holes, namely, post-Newtonian energy, fluxes and the (absorption-corrected) balance equation. The post-Newtonian inspiral templates are then presented both in the time and frequency domain. Finally, including the merger and subsequent ringdown phase, we briefly survey the two families of the full waveform models of compact binary mergers currently implemented in LSC Algorithm Library Simulation: the effective-one-body approach and the phenomenological frequency domain model.
