頻率比 例句

1. Ceviar living cells, which undergo devision 200 times faster than normal cells, contain a great variety of activated factors that stimulate fission of both organism and cells, and regeneration of cells, improving micro circulation and supply of nutrients, reducing melanin, and thus growing vitality and skin springiness, resulting from less wrinkles and shrinking pores
   魚子活細胞有旺盛的生命力，它的細胞分裂 頻率比 成熟細胞強200倍，內含多種活性因子，可啟動人體組織細胞的分裂和活化，刺激老化細胞更新再生，改善微循環，淡化黑色素，其高分子蛋白質有效的補充人體細胞和皮膚細胞的養份，增強機體活力和皮膚的彈性，修護鞏固基底層細胞組織達到去除皺紋、收緊毛孔、提升皮膚的顯著美容效果。
2. Female courtship signal of the brown planthopper was made of many continuous regular pulses and male ' s signal was made of similar syllabics and had two types with different time domain characteristics. second male vibrational signal differed from male courtship signal with wide spectrum range and regular syllabics frequency. time domain characteristics of signals in different individuals even the same individual were different
   頻 域特徵分析知，褐飛虱雌蟲求偶嗚聲信號的 頻 域特性較穩定，個體內 比 個體間差異小；雄蟲求偶嗚聲信號s 、 e片段 頻 譜范圍較寬，但主振 頻率比 較接近，差異不顯著； m片段 頻 帶較窄，主振 頻 率 mvf略小於s 、 e片段，變異較小； m片段脈沖重復 頻 率 prf為幻
3. When the frequency approaches zero, the factor approaches zero correspondingly ; 2 ) the amplitude of interaction factors changes with the incident angle of rayleigh waves and reaches maximum when is zero. moreover, with the increase of, the wave period shortens apparently ; ( 3 ) the amplitude of interaction factors decreases as the pile spacing increases and approaches to zero when the pile spacing is 15 ; 4 ) the amplitudes of interaction factors increase clearly with the increasing stiffness ratio of pile to soil ; 5 ) the lat eral seismic response of fixed - head pile groups is much smaller than that of free - head pile groups. moreover, the pile - group effects induced by rayleigh waves can be neglected ; 6 ) the lateral seismic response of piles at different location differs from each other
   得到了以下結論： 1 ）樁的相互作用因子隨 頻 率 呈周期性變化，在振動 頻率比 較低的情況下，樁的橫向相互作用因子也較低，當 頻 率 趨近於零時，相互作用因子也趨近於零； 2 ）樁的相互作用因子的幅值隨瑞利波入射角度的變化而變化，在= 0情況下幅值最大，且隨入射角度的增加，波動的周期明顯縮短； 3 ）樁的相互作用因子的幅值隨著樁與樁間距的增加而減小，至s d = 15時，樁的相互作用因子基本趨近於0 ； 4 ）在 頻率比 較低時，相互作用因子幅值隨樁土相對剛度 比 的增加而顯著增加； 5 ）樁頂固接可以有效地降低群樁的橫向地震響應幅值，由瑞利波產生的群樁效應可以忽略不計； 6 ）群樁中不同樁位的樁的橫向地震響應是不同的，每根樁所在的樁位對其橫向地震響應有很大的影響；刀樁數的增加並不能減小樁的橫向動力響應。
4. In order to reflect the characteristics of amplitude increase and frequency changing of seismic signal, a new automatic recognition method of seismic phase is developed based on the instantaneous amplitude and instantaneous frequency
   摘要為了充分反映地震信號振幅增大和 頻 率 改變的特徵，發展了一種以振幅和瞬時 頻率比 乘積為特徵參量的震相自動識別方法。
5. Measurements include frequency, frequency ratio with optional channel 2, period and peak voltage
