When ATRP of styrene was investigated with 1-phenylethyl bromide/benzyl a,a-dibromide mixture as initiator, the GPC chromatogram shows two elution peaks and the molecular weighs of the peaks are approximately in a 2/1 ratio. It suggests that benzyl dibromide is a difunctional initiator of ATRP of styrene. The analysis of end group using 1H-NMR also proves the result above.

采用1-苯基溴乙烷／α，α-二溴化苄混合引发剂进行苯乙烯的ATRP反应时，所得聚苯乙烯的GPC谱图为双峰，分子量相差一倍，初步证明了α，α-二溴化苄引发苯乙烯ATRP反应时是双官能引发剂，并用~1H-NMR对聚合物结构进行分析，进一步证明了α，α-二溴化苄引发苯乙烯ATRP时是双端同时增长的。

Based on the tissue culture, the effect of N-phenyl-N＇-1,2,3-thiadiazol-5-ylurea, 6- benzyla minoprine（6-BA） and 1-Naphthylacetic acid on spore germination, protonema develop- ment and bud differentiation in Entodon challenged was investigated in this paper. The whole process was observed and taken pictures. The results show that TDZ, 6-BA and NAA have no significant effect on the spore germination. During the process of protonema development, 1.0 mg/L NAA can promote the primary development of protonema significantly, and 0.4 mg/L TDZ promotes branches formation in inter- mediate stage of the protonema development.
