31. In the gun-type fission weapon two subcritical pieces of fuel are rapidly brought together. 32. If a reactor is exactly subcritical . 33. In general, supercritical flows are shallow and fast and subcritical flows are deep and slow. 34. Can you create a scenario where bringing together subcritical fissile masses results in a small explosion? 35. In subcritical experiments, plutonium is blasted with explosives too weak to set off an atomic explosion. 36. Implosion used explosives to crush a subcritical sphere of fissile material into a smaller and denser form. 37. In fact, the subcritical value of the stress intensity, designated as " K" 38. Depth values on the E y curve greater than the critical depth correspond to subcritical flow depths. 39. In a supercritical regime, in contrary to the subcritical regime the network has a giant component. 40. It follows that, in two dimensions, the supercritical phase is dual to a subcritical percolation process.
