结合环上NK_1（R）的无挠性
Absence of torsion for NK_1(R) over associative rings
摘要：
当R是有单位元的交换环时，若k是自然数且kR = R，则C. Weibel证明了SK_1（R[X]）没有k-挠。对于任意有单位元的结合环R，当kR = R时，我们重新证明了他的结果.
英文摘要：
When R is a commutative ring with identity, and if k is a natural number with kR = R, then C. Weibel proved that SK_1(R[X]) has no k-torsion. We reprove his result for any associative ring R with identity in which kR = R.
