查询词典 metacentric

6 The caryotype of giant panda's fibroblasts can be divided into two groups based on centromericindex.Group one of No.l-17 and X chromosomes is metacentric or submetacentric;Group two ofNo.18-20 is acrocentric little chromosomes.

第四代大熊猫皮肤成纤维细胞(PF4)染色体组型：2n＝42，根据着丝粒指数，总体可将其分为两种类型，1-17号常染色体和X染色体为中部或亚中着丝粒，18-20号常染色体为小型近端着丝粒。

The chromosome number is 2n=96, belonging to hexaploid species (2n=6x=96), and the morphological difference is not obvious among the 96 chromosomes. All the chromosomes are metacentric and submetacentric. Relative length ratio of the longest to the shortest chromosomes is 2.10. There is no satellite chromosome in all the 96 chromosomes. The karyotype formula is 2n=96=60m+36sm, the karyotype type is 2B, a higher karyotype evolution.

结果表明，该入侵种的染色体数为2 n=96，属六倍体物种，各染色体间形态差异不明显，均为中着丝粒或近中着丝粒染色体，最长与最短染色体相对长度比为2.10，全套染色体未见随体，核型公式为2 n=96=60 m+36 sm，核型类型为进化程度较高的2B型。

Thirty six homologous Pairs of chromosomes were autosomes, in which chromosomes, Pairs of 1 to 8 were metacentric.9 to 36 . And X was metacetric, Y chromosome terminal.

其中，1—8对常染色体为中间着丝粒染色体，9-36对常染色体为端部着丝粒染色体，X为中着丝粒染色体，Y为最小的为端部着丝粒染色体。

X chromosome was a large submetacentric chromosome. Y chromosome was a small metacentric chromosome.The relative length of chromosome was measured by AutoCAD software. The relative length of autosomes ranged from 1.545% to 4.921% in Yanbian yellow cattle and from 1.637% to 5.855% in Liyan hybrid cattle.

结果表明，延边黄牛和利延杂交牛二倍体染色体数目2n=60，公牛核型为2n=60，XY，母牛为2n=60，XX，其中29对常染色体均为端着丝粒染色体，X染色体为较大的亚中着丝粒染色体，Y染色体为较小的中着丝粒染色体。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
