查询词典 chromosome number

MRF-MBNN is also robust to different preassigned class number, the network will convergence to nearly same results in few iterations. The segmentation results for chromosome images is far better than those in the thesis are. It is same for Lena image.

MRF-MBNN网络除了具有MBNN网络对预定类别数的强鲁棒性和对不同类别数网络收敛快的特点外，将之用于染色体图像的分割效果远优于本文中所述的其他方法，而对Lena图像也获得了优于MBNN的结果。

Five pairs of 45S rDNA loci and two pairs of 5S rDNA signals were detected on chromosomes of Cucurbita moschata Duch. Luffa cylindrical Roem. contained five pairs of 45S rDNA loci and one pair of 5S rDNA loci. In Benincasa hispida Cogn., two pairs of 45S rDNA sites and one pair of 5S rDNA site were detected. In this species, 5S rDNA and one pair of the 45S loci were collocated closely in chromosome 7S. 45S rDNA chromosomal distribution patterns were highly conserved among the three species, althoufh their number varied markedly. The 5S rDNA sites on chromosomes among the three species were highly polymorphic.

南瓜有5对45S rDNA位点， 2对5S rDNA位点；丝瓜具有5对45S rDNA位点， 1对5S rDNA位点；冬瓜具有2对45S rDNA位点， 1对5S rDNA位点， 5S rDNA位点与其中一对45S rDNA位点都位于7号染色体短臂上，并在物理位置上紧密相邻。45S rDNA在这3种作物染色体上数目变化较大，但在染色体上都倾向分布在短臂末端，其分布模式较为一致。5S rDNA在这3种作物染色体上数目相对保守，但在染色体上分布的位置变化较大。

Results: observed typical changes of apoptosis(chromosome condensation, karyorrhexis, apoptotic body ) by TEM and Fluorescence microscopy. The number of apoptosis was increased with elevation of LPS concentration under the microscope.

结果 Hoechst荧光染色及电镜观察到脂多糖处理后滋养细胞染色体浓缩，细胞核裂解，见凋亡小体等典型凋亡表现，镜下随着脂多糖浓度的增加凋亡细胞数量显著增加。

The analysis of these data shows that in the process of evolution the X chromosomes are as conservative as those in other mammals and the intraspecific and interspecific changes of autosomes follow such a rule:the increase of one chromosome in 2n number is always accompanied by the increase of two acrocentrics and the decrease of one metacentric or submetacentric,and vice versa.

对这些材料所进行的分析表明，鹿属动物在进化过程中，X染色体是很保守的，而常染色体的变化，无论是种间还是种内，全是2n数每增加1条，中部或亚中部着丝点染色体数就减少1条，而端着丝点染色体数就增加2条，反之亦然。
