Terahertz radiation, which is a kind of electromagnetic wave between the infrared and microwave bands, belongs to far-infrared band. THz time-domain spectroscopy which developed in the 1980\'s has the advantages of high signal to noise ratio, obtaining the absorption coefficient and refractive index of the sample at one time , low energy that can not distroy the biology organise and so on.

太赫兹辐射是指频率位于微波和红外光之间的电磁波，属于远红外波段；20世纪80年代发展起来的THz时域光谱技术，具有信噪比高，能同时获得样品的吸收系数和折射率，能量低，不会对生物组织造成破坏等优点，在材料和生物学等领域得到了迅速的发展和广泛的应用。

The aromatics having carbon number of n are retained after n-Cn+3 on the FFAP pre-column, and were cut and back flushed after the elution of n-Cn+3, onto an a apolar analytical column and were separated according to their boiling points.

由于在FFAP毛细管预柱上芳烃在比高它三个碳数的烷烃之后出峰，可以通过阀切换操作把芳烃反吹入非极性OV-1分析柱中按照沸点进行详细分离。

By mechanical test of the steel strip and simulation of strip deformation in tension leveling using finite element method,characteristic features of the strip were obtained,such as;high yield stress,high yield ratio and low plastic elongation as the basic reason of difficulty in tension leveling and shape control.

通过对全硬钢的力学性能的测定和拉矫变形行为的有限元仿真，发现屈服应力大、屈强比高以及断裂时塑性延伸小等特性是造成镀锌后全硬带钢拉矫困难和板形难以控制的根本原因。

Hence it was that the Spanish Rite was much more regulated than the Gallican, and Toledo at times, though not very successfully, tried to give liturgical laws even to Gaul, though probably only to the Visigothic part of it.

因此，这是西班牙仪式更是调节比高卢圣，并托莱多有时，虽然不是非常成功，试图让礼仪法律甚至高卢人，但大概只有到Visigothic的一部分。

The advantage of the product is separation process evenly,easily control,and feeding chromes adjustable high,high concentrate.recovery ratio high,less space,water saving,simplestructure,no motor,dealing amount large,fix easily,convenient operated,small inves etc.

本设备具有选别过程稳定、容易控制，给矿浓度允许变化范围大，富集比高、回收率高，占地面积小、耗水量少，结构简单，无需动力，处理量大，安装简易，操作方便，投资小见效快等优点。

It found that ninety-seven percent happen in low and middle income countries.

撒哈拉以南非洲的死亡率为世界最高，比高收入国家的死亡率高出7倍。

Then through series experiment of coupling beams only add diagonal bars on the basis of traditional reinforcement with Zhanlin, we can conclude this plan for steel bar can satisfied the ductility demand of short-span coupling beams in tube body structure of Chongqing area. Through the computer simulation we can know: Procedures outputs coupling beams'ductility demand mainly in 1.5 to2.0 (maximum value 2.2), comparing the simulation of 8 or 9 degree , we can see the response of the whole structure and yielding degree are much small.

计算机分析程序输出的连梁的转角延性大多在1.5到2.0之间(最大值2.2)，对比以往本学科点对8度和9度等高烈度区的同类型结构的地震作用模拟分析可以看出，6度区大震作用下不管是结构的整体反应还是各杆件的屈服情况都比高9度和8度区小很多。

The design and manufacturing processes of ultrasonic TR probes for manual and automatic inspection of the wheel rim s were introduced.

介绍了用于车轮轮辋超声波检测用的手动和自动探伤TR探头的设计和制造工艺，制造出了灵敏度高、盲区小、信噪比高的TR探头，在现场轮辋探伤中取得了良好的结果。

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。
