After the symmetry breaking, the first operator ${\mathcal O}_{t1}$ directly modifies the strength of the Yukawa coupling of $t \bar t H$ without changing the relation between the top quark mass and the SM top-Yukawa coupling. The second one ${\mathcal O}_{Dt}$, which includes the covariant derivative $D_\mu$, describes the momentum dependence of the effective top-Yukawa coupling. These two operators determine the behavior of the effective top-Yukawa coupling below $\Lambda$, so that it is important to separately measure these operators to determine the direction of fundamental theories which describe higher scales above $\Lambda$. The effect of these dimension-six operators has already been discussed for the process $e^- e^+ \to t \bar{t} H$ by Han et al[@han]. In this paper,
