摘要
受限制扦值空间的约束条件形式有两类，一类是对多项式系数的约束方程，每方程系数对应于一向量C，另一类是限定基函数形式，每个基函数构造形式中的组合系数组成一个向量Q。将扦值的唯一可解性要求转化为对C或Q的约束条件。
There are two forms represent restricted conditions. First is restricted equations for coefficients of polynomial. The coefficients of a equation correspond with a vector C. Another form is to restrict the combinatioanl form of a basic functions. whichcombinational coefficients correspond with a vector Q. In this paoer the conditions of the unique solvability are tramslated into the restricted condition for C or Q.
