减弱作用 meaning in English
attenuation
Examples
- Simulation on abated effect of nylon net with different porosities on wind - blown sand in wind tunnel
不同孔隙度尼龙网对风沙流减弱作用的风洞模拟 - The deceleration occurs with initial asymmetry in outside region of rmw with 13h period and the amplitude reduces with time
Rmw外围扰动使tc强度减弱，这种减弱作用也表现出震荡形态，震荡周期约13h ，其震荡强度随时间具有减弱的趋势。 - The results indicated that the centrifugal force reduces the localization ; when the young ’ s modulus of all blades are in the tolerance of 5 % , the blade - disc can regarded as an cyclic symmetry system
结果表明,离心力对失调叶片轮盘系统局部化振动有减弱作用;所有叶片弹性模量在5 %误差范围的随机失调系统,其固有频率与非失调相差很小,即失调叶片?轮盘系统可以按照循环对称结构进行模态分析。 - The obtained results indicate that compared with the clay layer , the liquefied sand layer takes a decreasing effects on the short period component of the surface ground motion and the effects increase with increasing of the thickness 、 depth and width of the liquefied sand layer ; the liquefied sand layer takes a increasing effects on the long period component of the surface ground motion but the effect is not obviously ; to the input earthquake wave , the demarcation point of strengthens and weaken is about 0 . 6s
主要结论为:和同样的粘土层相比,液化层的存在对地表上地震动的短周期分量主要起减弱作用,且减震效果随着液化层埋深、厚度的增加而变强;对长周期分量主要起加强作用,但是效果不太明显;对所输入的地震波来说加强减弱的分界点所对应周期为0 . 6s左右。
