几何重数 meaning in Chinese

geometric multiplicity

First we consider the spectral properties of the operator corresponding to this system and obtain that all points on the imaginary axis except for zero belong to resolvent set of the operator , zero is an eigenvalue of the operator and its adjoint operator with geometric multiplicity one
先讨论了对应于该系统的主算子的谱特征并且得到了在虚轴上除了0点外其它所有点都属于该主算子的豫解集， 0是该主算子及其共轭算子几何重数为1的特征值。
