对一类具有第二类约束的p膜模型进行了BRST量化。在相空间进行BFV扩展后，p = 1时约束代数与空字符串的约束代数重合。结果表明，在这种情况下，可以或不可以获得空串的临界维数，这取决于算子序的选择和相应的真空状态。当p > 1时，不允许在p = 1的情况下导致临界尺寸的算子排序。可容许序对嵌入时空的维数没有限制。最后，对超对称零膜进行了推广。
BRST quantization is carried out for a model of p-branes with second class constraints. After BFV extension of the phase space the constraint algebra coincides with the one of null string when p = 1. It is shown that in this case one can or can not obtain critical dimension for the null string, depending on the choice of the operator ordering and corresponding vacuum states. When p > 1, operator orderings leading to critical dimension in the p = 1 case are not allowed. Admissable orderings give no restrictions on the dimension of the embedding space-time. Finally, a generalization to supersymmetric null branes is proposed.
