摘要

Gravitational waves (GWs) are a marvelous prediction of general relativity.The GW waveform from a compact binary coalescence is theoretically predictable,and different binary systems emit GWs in different frequency bands.The fre-quencies of GWs emitted by stellar-mass binaries fall within the detection band of ground-based detectors (10-104 Hz).GWs at lower frequencies (10-4-1 Hz) emitted by massive black hole binaries (MBHBs) have wavelengths larger than the earth itself.Deploying a GW detector large enough to efficiently detect them requires going to space.To achieve this goal,several space-based GW detection projects,such as LISA,Taiji,and TianQin,are proposed,planning to launch spacecraft to space in the early 2030s.
