圆环

Tower about 2 meters, Taki prototype for the flat stone base, the tower is spherical, hollow, surrounded by ring of five small hole, to make gourd-shaped tower.

塔高约2米，塔基为扁原形石座，塔身为球形，中空，四周环有五个小圆孔，塔顶作葫芦形。

Ma chain of title, such as two-phase sets, the two ends flat button ring wearing an external ladder. 1991-94 in Bali Township Luocun Guo Rong people have unearthed the tomb of copper Ge, such as cutting and traveling more than 80 pieces of equipment, vehicles軎III are nail holes, such as the long-barreled, or waist-shaped cylinder, the first軎or collect, such as taper or round drum hemisphere.

In place of gears, most CVTs use one or more cones, discs, balls, belts, toroids or other shaped devices for gradually changing ratios.

代替齿轮，多数电容使用一个或多个圆筒，圆盘，球，皮带绕环或其他形装置，逐步改变比例。

The effects of gap size, shape, inclination angle, pressure and form losses of two ends of annuli were discussed. Based on experimental data and theoretical analysis results, a new half-empirical correlation was also derived which can accurately predict the CHF of vertical annuli, circle tube and rectangular channel in a very wide range of H/De values.

在实验和理论分析的基础上，提出了一个新的，可用于计算竖直环隙、圆管及长方形流道内自然对流沸腾临界热负荷的半经验公式，其计算精度和适用范围较现有的计算公式有显著提高，原则上不受H/De值大小的限制。

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。
