极期

A novel Belousov-Zhabotinskii type oscillating reaction was observed in a closed serine-BrO^-~3-Mn^2^+- H2SO4 system(Ser-BZ system), which exhibited the followign characteristics:(1)Although Ser is unable to be brominated, the sustained oscillations could still be observed in the above system under batchreactor conditions even in the absence of either acetone or inert gas flow.(2)The present oscillations displayed extremely short induction period(0) and very few oscillation number(1).(3)Cl^-, acrylonitrile, or Br^- could effectively inhibit the oscillations. However, in the case when enough Ag^+ was addedinto the system to completely inhibit the oscillations in , the oscillations on the Pt-electrode could still be observed.

首次报道了间歇釜中以丝氨酸-BrO^-~3-Mn^2^+-H2SO4为体系的新型BZ类振荡反应，其特征如下：(1)虽然Ser不能发生溴代反应，但即使在无丙酮或惰性气体流时也能在间歇釜中观察到持续振荡；(2)振荡诱导期极短(～0)，振荡次数较少(1次)；(3)振荡反应受到Cl^-，Br^-，丙烯腈等的抑制；但当加入足够量Ag^+使的振荡抑制后，仍可在Pt电极上观察到振荡现象。

Exposure ages of bedrock samples taken from two nunataks in the Grove Mountains, interior East Antarctica, are studied by dating in situ produced cosmogenic 10Be and 26Al. The results indicate that the minimum exposure time of the five samples are all about 2Ma, much older than that of Last Glacial Maximum.
