首先推导出纵向弛豫和横向弛豫与磁化强度矢量偏转角关系的数学表达式。
A mathematical formula of the relation between longitudinal relaxation or transverse relaxation and the flip Angle of magnetization vector was deduced and its programme was designed.
本文推出了磁化强度矢量与极化强度矢基的相对论变换关系，证明了M和P可构成两个洛伦兹不变量，从而可加深对M和P的理解。
The transformation of polarization vector and magnetization vector is derivedand thereafter two Lorentz invariants containing M and Pare proved.
