A linkage map was constructed using 151 polymorphismic markers.The map spans1841.9 cM covering 12 rice chromosomes with an average interval of 12.1 cM,which wellintegrated the markers from the high density linkage maps of rice.

以151个多型性标记位点构建了12条染色体的遗传连锁图谱，该图谱以标记间平均间距为12.1cM覆盖了水稻基因组的1841.9cM，该图谱较好地整合了目前已发表的水稻遗传图谱上的分子标记。

By use of some atom parameters in optical-field-ionized plasmas obtained from the extended Cowan program based on Maxwell to suit any electron distribution with the help of additional program, the peak gain coefficient of Ni-like Kr system is calculated for the ion densities of 1×10 17 cm -3 and 3.2×10 17 cm -3 respectively after considering Doppler broadening and natural broadening.
