Ku prattled away, even dragging in the bed plank incident

反射波振幅与入射波振幅的比率称作反射率或反射系数。

This paper discusses the classification of seabed sediment using normally incident, high frequency sound pules.

本文提出一种垂直入射声脉冲遥测海底表层沉积物类型的方法。一些作者已经指出，海底反射系数可以作为特征量用于识别沉积物类型。

A new method based on proportional-integral-derivative control is proposed to measure photoionization cross sections in GaN materials by analysis of release and recaptures carriers of deep centers by incident light.

Thus the absorption of a system is the fraction of the incident radiation which is absorbed by the system.

因而一个系统的吸收率就是被系统吸收的入射辐射的份额。

Finally, the parameters, such as density, thickness of porous media, thickness of steel of each material in air and porosity, pore size, thickness of porous materials, thickness of steel and incident angles in water were investigated and also the influence on the sound absorption and insulation were discussed.

最后，分别就空气中以及水中的材料参数，分门别类的观察其对吸音与隔音的影响。在空气中所讨论的参数，有多孔材密度、多孔材厚度、钢材厚度。在水中所讨论的参数，有多孔材孔隙率、孔隙尺寸、多孔材厚度、钢材厚度、声波入射角度。

According to the formulae on radiation and radiation resistance in antenna theories, the radiation characteristics are illustrated that the radiation of under considered can be neglected.

运用小波矩量法求出导线中的电流分布，进而给出两个尺寸不同的圆形电感在平面入射波作用下的辐射方向图，并进行分析比较。

The analysis on the numerical simulation results of the azimuth characteristics of the acoustic field generated by the transmitter showed that the acoustic energy generated by the phased arc array transmitter could radiate onto the sidewall of oil well in a certain azimuth range.

对模拟声场的方位特征进行的分析表明：相控圆弧阵声波辐射器产生的声波能量基本向某一周向角范围的井壁入射，进入地层的声波在一定周向角范围内传播。

The numerical simultion results were analyzed on azimuthal characteristic of acosutic field. The analysis results show that the acoustic energy generated by the phased arc array transmitter radiates onto sidewall in certain azimuthal range.

对模拟声场的方位特征进行的分析表明：相控圆弧阵声波辐射器产生的声波能量基本向某一周向角范围的井壁入射；进入地层的声波在一定周向角范围内传播。

Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.

而后，采用200kHz至350kHz频段的入射波进行了实验验证，并每隔10kHz绘出一条峰值一时间的曲线，通过拟合峰值点，找到对应的时间，从而准确的计算出了缺陷的所在；应用锥形探头的热交换水管的实验表明，超声导波可以在管道中传播了近50米的距离，且不受弯头的影响，从而使得长范围、大规模检测成为可能，水载管实验说明了离面位移和能量可能会发生泄漏的特性，为导波的深入研究和应用作了铺垫。

All these accessories, plus a model rifle, were tagged with retroreflectors, which can reflect a beam of radiation back to its source regardless of the angle of incidence.

这些配件以及一把模型步枪上，全装著复归反射器，可以把任何角度的入射光束反射回原来的发射点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
