摘要：
Some new moderate degree cubature formulas for tetrahedra are derived. The suitability of various types of rules for the finite-element technique is discussed exhaustively. Consequently, the newly developed formulas supplemented by lower degree known ones are tabulated for the purpose of direct application in finite-element programming. All the formulas are presented in a virtually machine-independent form.
