Discussions are given of the fate of Ms2 during translocation in the hexoploid triticale, the exchange of the names for 4A and 4B chromosomes in common wheat and the possible expoitation of the new locus Ms2 (4BS), and the following speculations are made: In geneic genes of allopolyploid organisms the donor chromosomes tend to be intergenomically translocated to their phylogically and evolutionarily close chromosomes with the same order number and the same arm; it is cofirmed that the 7th International Conference of Wheat Genetics was right to exchange the names between chromosomes 4A and 4B of common wheat in 1988; and as a new genetic marker and a breeding tool for all the chromosome B-carrying species in the tribe of Tritceae, Ms2 (4BS) may have wide application in building and expanding the gene pool of germplasm resources of various species of wheat.

对 Ms2基因在六倍体小黑麦与原太谷核不育小麦远缘杂交中易位时的走向，普通小麦4A与4B染色体的互换更名以及 Ms2(4BS)新位点的开发利用进行了讨论：认为异源多倍体生物核基因的组间易位倾向于从供体染色体向进化亲缘关系较密切，且染色体序数与染色体臂相同的部分同源染色体易位；1988年第7届国际小麦遗传学会对普通小麦4A与4B染色体的互换更名是正确的； Ms2(4BS)作为一个新型的遗传标记，作为小麦族内所有携带B染色体组的物种的育种工具和在拓建各类小麦种质资源的基因库等方面均有广泛的用途。

The main objective of this project is to research and develop a novel and high efficient video codec framework based on wavelet techniques, especially to address the heterogeneousness of video networks, the fluctuation of transmission bandwidth and the diversity of video-stream receivers.

If the tectonic uplift is not considered, the relief of Dabie orogen will reach at least 3km in Late-Cretaceous. As to the value of the relief reduction factor in Dabie orogen at 90Ma, the largest value appeared in northeast region, followed consecutively by the core and southeast Tanlu fault zone, with the smalleast value appeared in northwest and southwest region. The results reflect the strong uplift difference between core and North Huaiyang flank in Dabie orogen during doming extension period. Relief in the core region and southeast Tanlu fault zone is higher than those in the peripheral regions, northwest and southwest flanks are more stable than other regions.
