point symmetry

基本解釋

Firstly, we calculate the Lie point symmetry of 1+2-dimensional nonlinear evolution equation:Which arises from the motion of plane curves in affine geometry.
我們首先計(jì)算了來自射影幾何的平面曲線運(yùn)動(dòng)的非線性發(fā)展方程：所容許的李點(diǎn)對稱群。
Firstly, the Green function's source point and field point symmetry and geometry symmetry are discussed, and based on these, symmetry properties used in the matrix solving are discussed.
首先分析了格林函數(shù)的場點(diǎn)源點(diǎn)對稱性和幾何對稱性，并由此入手，對對稱性在速度勢求解矩陣中的應(yīng)用進(jìn)行了分析。
They belong to C_(2V) local symmetry. From the point of view of point-charge model the ligand field semi-quantitative calculation is applied to molecules with C_(2v) point group symmetry.
指出它們均具有C_（2v）局部對稱性，并從晶體場點(diǎn)電荷模型出發(fā)對具有C_（2v）對稱性點(diǎn)群的分子進(jìn)行了配位場半定量計(jì)算。
