In Vertebrate, mtDNA is generally a 15-22 kb circular genome. mtDNA is arranged in the same relative order in almost all vertebrate species from teleost fishes to eutherian mammals.

脊椎动物线粒体DNA是一个长度约为15-22kb环形结构。mtDNA呈母系遗传，在大部分的脊椎动物中具有相对保守性。

In animals, mitochondrial DNA is generally a 15-22 kb circular genome containing 37 genes: 13 protein-coding genes, two rRNA genes, and 22 tRNA genes, as well as a control region. All 37 genes are arranged in the same relative order almost in all vertebrate species from teleost fishes to eutherian mammals. In recent years, mtDNA has been widely used as a useful marker system in numerous phylogenetic analyses in vertebrate relationships.

脊椎动物线粒体DNA是一个环形结构，长度约为15-22kb.mtDNA呈母系遗传，具有相对保守性，已被广泛应用于分析动物个体鉴别和动物类群间的系统发生关系。

In the axisymmetric section, the axial strain in excircle is maximum, but the maximum radial strain is in inner bore, and the radial strain contrast is used to reflect the variation trend of wall thickness in this ring section.

在轴对称截面的外圆上轴向拉应变最大，内孔处径向压应变最大，并用径向应变对比度来反映该环形截面壁厚的变化趋势。

The method of multiple scales was used to solve the Duffing equation, the solutions were used to analyze qualitatively the effect of boundary conditions, ratio of damp, external excitation, and ratio of inner radius to outer radius on the second-harmonic resonance of an annular thin plate.

用多尺度方法求此振动控制方程的3次超谐共振解和1/3亚谐共振解，并且定性地探讨边界条件、内外半径比、激振力和阻尼对环形薄圆板在这两种次谐共振下的动态响应。

Bonnet joint varies from flat face gasket-joint to ring-type bonnet joint, depending on class.

阀盖连接方式从平面垫圈连接到环形阀盖连接，压力等级不同，连接方式也有所不同。

Probably the most problematic situations are the naturally fractured formations where the operator may face total loss with no mud return in the annular.

大概是最有问题的情况下，是自然形成的裂缝所在的营办商可面对全损无泥回报，在环形。

Wavelength requirements, fair factor and wavelength reusability of ring and real networks are systematically analyzed under uniform and non-uniform traffic patterns. Numerical results show that the heuristics can achieve a great performance of load balancing and wavelength resources are utilized efficiently.

我们以环形网络和实际网络为例，对均匀和非均匀业务模式下网络的波长需求、网络的均衡因子和波长重用度进行了系统的分析，数值结果表明本文的启发式算法能获得良好的负载均衡性能并有效地利用了网络的波长资源。

Besides the uninterrupted ringed mountains, a couple of small hills in the center have the soil surface. Inside these small hills, there are one or more smaller hills, some are made up of rocks, and the shape is like a big barrier, just like the fin of whale emerging from the water.

除了连绵的环形山外，在中心区有一些由几个小山组成的半环抱的表面是土壤的山体，它们的中间有一座或几座更小的小山包；有的主要以岩石为山体，造型是一座巨大的屏障，好象鲸鱼的背显露了出来。

Besides, the factors which affected the distance between the two positions and the size of the flattop profiles were studied.

此外，还研究了对于不同的聚焦透镜焦距和环形光阑中心拦截比，不同空间相干度对平顶光束的影响。

The experimental investigation shows that the size of the flattop profiles and the distance between the two positions decrease with the increase of the spatial coherent length and the obstruction ratio of the annular aperture .

研究表明，两处平顶光束的大小及两处平顶光束之间的距离随着空间相干长度和环形光阑拦截比的增大而减小，随聚焦透镜焦距的增大而增大。
