In addition, the curve of terahertz absorption coefficients can be fitted by a straight line with a slope of 1.92. From the results of scanning electron microscope, the ranges of inner diameter and outer diameters of the sample were from 5 to 15 nm and from 15 to 25 nm, respectively, and its length was in the order of micrometer.

检测结果显示，在0.2～2.0 THz内，样品折射率随着频率的增加而减小，吸收系数却随着频率的增加而增加，并可以拟合斜率为1.92的直线；样品的内径为5～15 nm、外径为15～25 nm，且长度达到了微米级，样品含C量大约为94%，其他为O和Cl杂质元素。

For armoured or copper-tape-screened cable, not less than 12 times of cable diameter

无铠装或铜带屏蔽结构的电缆，应不小于电缆外径的12倍

Meanwhile, the origin and the adjacence of the basilic vein were also observed.

用游标卡尺来测量贵要静脉的长度和外径。

The basilic veins were exposed carefully; their diameter and length were measured with vernier caliper.

用游标卡尺来测量贵要静脉的长度和外径。

According to the present invention, there is an advantage in that an outer diameter of the piston (20) is not changed during its assembling process, since the piston pin (30) can be fastened to the piston (20) merely by causing only the caulking portions (26) of the piston (20) to be subjected to the plastic deformation.

根据本发明，有一个优点就是，既然活塞销(30)仅仅通过活塞(20)的箍紧部分(26)的塑性变形就能够被固定在活塞(20)上，因此活塞(20)的外径在其装配过程中不会变化。

Experiments showed that mixing property in pipe fluidized bed with relative distance of blowpipe equal to 3.2 is better than that of traditional platefluidized bed.

结果表明，当布风管间距与布风管外径比为3.2时，管式布风流化床比板式布风具有更好的混合效果。

As with all wheel brushes, you should use the largest diameter spindle possible because with a large wheel brush at the proper RPM, a great deal of force is exerted at its periphery.

和其他轮刷一样，您也可以使用外径较大的扁轮刷，若转速恰当，轮刷外围可以发挥尽可能大的作用力。

The stator inner diameter of Powerformer is calculated according to the bend radius of cable and the slot shape is determined by the outer diameter of cable, a rated voltage 35kV and rated power 2550kW Powerformer is designed on the basis of this design method.

即根据电缆的弯曲半径计算电机的定子内径，由电缆的外径确定电机的定子槽形，在此基础之上设计了一台容量2550kW，额定电压35kV 的Powerformer。

Radius of a bend: take the biggest radius of a bend of a cable, oil pipe, gas pipe or water pipe as a reference value and leave 10% of the space as a margin.

内宽：选择较粗的一些电缆油管气管水管等，其外径之和作为拖链内宽的参照，并留有至少10%的宽度空间。

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。
