A six people s rushing replies an implement, use some s switches in toggle switch K0 ~ K5 is that ON accomplishes when rushing to reply button , nobody rush to answer, 6 numerical code circulation takes turns at demonstrating 1 ~ 6 (horse races) , who rushes to reply the numerical code stops having a ride on a horse , first, whose serial number, has simultaneous light of 6 numerical codes again afterwards the key presses down. System denies responding to, until this place is OFF batch , the wheel restoring 1 ~ 6 horse races starting time as soon as rushes to answer.
％ A 2D homogeneous convection-diffusion case (u=exp(-ex*deta*x-ex*deta*y) with a square with
％ all Dirichlet boundary, note that reaction coefficient is not zero
％ by indirect BKM
