Abstract：
According to the principle of "Uniform magnetization", the field-shape of plane head quadrupole of "coil replacement" and "Quasi coil replacement" is analysed by means of series expansion. The magnetic field and gradient expression are given in the plane y=0. The optimization relations of height-width ratio of the magnetic piece are also presented.
