课题小组选择了140个活动星系核，或简称agns，这些星系都放射出大量的X射线，X射线能穿透阻挡观测的气体和尘埃。
The team chose 140 active galactic nuclei, or AGNs, by selecting galaxies that emit a lot of X-rays, which can Pierce the galactic gas and dust that might otherwise block the nuclei from view.
为了同时兼顾穿透深度、成像对比度和信噪比三方面的需要，选择微波辐照频率时应该采取折中选取的原则。
As for the choice of the microwave irradiation frequency, the trade-off must be made in order to insure the penetration depth of the microwave signal, imaging contrast and signal-to-noise ratio.
在工业CT设计中，为了选择闪烁体的种类和几何尺寸，需要知道韧致辐射光子穿透闪烁体的能量和通量分布。
In the design of industrial ct, the knowledge of energy and flux distributions for bremsstrahlung photons through crystals is necessary to select scintillator's type and dimension.
同样重要的是，它的操控性能评估以确保其选择桩所需的能力和穿透深度可在一个合理的行驶阻力。
It is also important to assess the driveability of the selected pile to assure that the required capacity and penetration depth may be achieved at a reasonable driving resistance.
只选择出面向窗户的，可能被从玻璃中穿透的光线所打亮的面。
Select only the surfaces facing the window that would be hit by the light coming through the glass.
在海冰覆盖的条件下，PAR的观测结果与无冰海水的PAR有明显差别。由于海冰选择性的吸收，穿透海冰进入海洋的PAR组分已经不同，海水对PAR的衰减系数也会相应变化。
But under sea ice, the attenuation coefficient of PAR is little bit different, as the spectrum of the light has been changed by selective absorption through the sea ice.
制备的腐殖酸键合硅胶用于固相萃取时，表现出穿透体积大，单位质量吸附量高，选择性高的特点。
The humic acid bonded silica gel has characteristics of larger penetrating capacity, high adsorbance per unit quality and high selectivity when it is used for solid phase abstraction.
