Making use of the momentvector and radius vector of rotation, the lateral buckling of thin-walled members are analyzed.
以弯矩矢量和转角向径为工具,分析了薄壁构件的弯扭屈曲。

The statistical average value of electronic polarization vector, magnetic moment, energy and paramagnetic susceptibility, which are proceeded under constant magnetic field, is discussed.
In such case, it is proved that, for the unique existence of solution, there must be given in addition the principal vector and the principal moment of the external forces on each boundary contour.
