antiradical

The purpose of the study was to investigate whether the small fiber evoked dorsal root reflex (DRR) can be obtained by electrical stimulation of the peripheral nerve in rats.

在距脊髓约 15mm处切断大鼠L5背根 ,将中枢端分成 4～ 5条细束 ,电刺激腓肠神经在背根细束上记录背根反射 (dorsalrootreflex ,DRR)。

In this paper, we study graded radicals and reflected radicals of general groupgraded rings.

Stewart在文[1]中讨论了六种分次根与相应自反根的关系，作为该文的继续，本文首先定义了分次Koethe根并讨论它与Koethe自反根的关系，其次，进一步给出Levitzki自反根的刻画，最后，我们指出文[1]的两个错误结论，证明分次vonNeumann根与vonNeumann自反根恰好相等。
