If R satisfies =0 for any elements x ,y in R then ⑴when k =1, R is commutative;⑵when R has the unity, R is commutative;⑶when R has at least one right regular element and f 2 (t 1,t2) has no terms with degree1 such that Fn= F then R iscommutative when R has at least one right regular element. Here we would like to point out that the above results generalized the results of Fu changlin ,moreover generalized some results of other references . This results enriched the commutative conditions of any ring.

The nonobvious relation is between the register state R of the original program and the location state R′ of the transformed program. Given that each pseudo-register r is mapped to the location j, we could naively require that R = R′j(r for all r.
原始程序的寄存器状态R和变换后程序的存储状态R′之间的关系并不那么明显,假定每个伪寄存器r映射到分配单元j,我们可以简单地要求对所有r有R = R′j
