BRepLProp：（local property 局部性质）

• These global functions compute the degree ofcontinuity of a curve built by concatenation of twoedges at their junction point.
  BRepGProp ：（global property 全部性质）
  -Provides global functions to compute a shape’s globalproperties for lines, surfaces or volumes, and bringthem together with the global properties alreadycomputed for a geometric system.The global properties computed for a system are :- its mass（质量）,- its center of mass（质心）,- its matrix of inertia（惯性矩阵）,- its moment（惯性矩） about an axis,- its radius of gyration（回转半径） about an axis,- and its principal properties of inertia such as principal axis, principal moments, principal radius of gyration.
