Abstract 摘要	Through 21cm intensity mapping observation, large scale structure of matter distribution can be obtained quickly. By observing the baryon acoustic oscillation signal, one can determine the equation of state of dark energy. Such an experiment could be done in China quickly and with relatively low cost.
