英文摘要	We analytically calculate the scalar induced gravitational waves (SIGWs) and find a log-dependent slope of SIGW in the infrared regions (f < f(c)), namely n(GW)(f) = 3 - 2/ln(f(c)/f), and nGW(f) = 2 - 2/ln(f(c)/f) near the peak if the power spectrum of scalar curvature perturbation is quite narrow, where f(c) is roughly the peak frequency. Such a log-dependent slope can be taken as a new template for distinguishing SIGW from other sources.
