We make a comparison in tailpipe noise between straight pipe and muffler, it is seen that there is a sharp peak in low frequent.
由于隧道开挖采用多段微差爆破,所以多数实测爆破地震波中存在多个优势频率峰值,能量带分布很宽。
Multi-millisecond blasting is used in tunnel excavation, so there are several dominating frequency peak values in actual observation blasting seismic, and the energy distribution belt is wide.
大的峰值会使功率放大器饱和,在子载波间产生交调干扰和导致能量的带外弥散。
These large peaks cause saturation in power amplifiers, leading to intermodulation products among the subcarriers and disturbing out of band energy.
研究结果:滑带土的峰值强度和残余强度比较接近,成线性关系;塑性指数能较好的用来估算残余强度。
Research results:Residual strength of slip soil has linear regression with peak strength; plastic index can be better used to estimate residual strength.
在平面应变压缩条件下,砂土在峰值应力状态附近出现应变局部化现象,在残余状态最终形成一条V型剪切带。
Under plane strain condition, the strain localization starts around the peak stress state; and a V-shaped shear band is formed at the residual stress state.
对应于磁阻抗峰值的频率随快淬速率的增加而趋于高频,这归因于薄带厚度减小的缘故。
The frequency where maximum magnetoimpedance occurs shifts to high frequencies with an increase of quenching speed, which is attributed to the drop of ribbon thickness.
拉曼光谱要么不显示金刚石1332cm - 1峰,要么显示的峰很弱。但D带和石墨峰值却清晰可见。
The Raman spectra either did not show the diamond 1332 cm-1 peak or the peak was very weak, while the D-band and the graphite peak appeared clearly.
对带底圈重力式网箱在纯波浪作用下的锚绳受力进行了研究,获得了锚绳受力峰值及相位关系的基本规律。
The force mechanics of the wave and current acting on the Gravity Cage is rather complicated since the Gravity Cage is a kind of flexible floating structures.
此外,岩石材料的剪切带分叉发生在峰值应力之后,随围压增加而逐步远离峰值点。
Furthermore, the localization shear band bifurcation takes place at the point in the strain softening area, and the point would be far from the peak point with the increment of lateral pressure.
