She had never realized the passage of the years, she had never imagined that her youth was waning . 她从未意识到年华的流逝，她从未想象过自己的青春正在衰减。
Whether the decreased solar activity was somehow responsible for the little ice age is still unknown . 太阳活动的衰减是否会以某种方式引起小冰川期，这还不清楚。
In benzene or ethyl acetate solution rates increase linearly with methyl methacrylate concentration . 在苯或乙酸乙酯溶液中其衰减速度随甲基丙烯酸甲脂浓度呈直线地增大。
Two color pyrometers were developed to solve the problem of signal attenuation by intervening smoke or fumes . 为了解决由烟或气所引起的信号衰减问题，研制出了双色高温计。
The optimum design of detector arrays for the attenuation of surface waves and of ambient noise is a complex subject . 为衰减面波和外界噪声作检波器组合的最佳设计是一件复杂的事情。
If the sample absorbs at the frequency of the impinging light, then the light leaving the prism will be attenuated . 如试样吸收一部分入射光，那么离开棱镜的反射光，将衰减一小部分。
If we were to try burying our detectors in order to attenuate the surface waves, we would soon grow discouraged . 如果企图用埋置检波器的方法来衰减面波，很快就会发现这种做法是徒劳的。
Because the larger the event, the larger the number of oscillations of the transducer before they decay below the trigger level . 因为事件越大，传感器在它衰减到低于触发器电平之前的振荡次数越多。
To obtain an accurate measure of the precessional rate one has to attenuate the signal proportional to torquing current by cosβ . 为了准确测量进动角速度，必须使与加矩电流成比例的信号衰减cos倍。
The beacon will have a limited beamwidth and if the body-to-beam angle exceeds this a serious loss of signal will result . 这个信标器的波束宽度有限，如果弹体波束角超过了它，信号就会发生严重的衰减。
