例句與造句

1. ( 三 ) under the dynamic load of the explosion , the numeric analysis has been done and achieve the rule as follow : ( 1 ) when the frequency of vibration is 0 . 3hz , the acceleration of the slopes top gets the maximum ; so 0 . 3hz is believed the natural frequency of the slope as a whole ; ( 2 ) the vibration of explosion can been magnified because of the condition of the landform , when the relative altitude is up to 45m , the acceleration of horizon gets the maximum ; when the relative altitude is up to 100m , the absolute value of acceleration and the deformation of horizon is larger than that in the bottom of the slope ; ( 3 ) in the period of forced vibration , at the top of the slope , the acceleration of horizon become larger and larger ; at the middle part of the slope , it becomes smaller ; ( 4 ) when the explosion velocity of is much little , the shallow part destruction is the primary deformation of the slope
   (三)采用模態(tài)疊加法針對爆破動力作用，進(jìn)行邊坡的動力響應(yīng)分析，得出了以下結(jié)論： ( 1 )振動頻率為0 . 3hz時，坡面頂部水平向加速度峰值最大；綜合考慮，可認(rèn)為該邊坡的自振頻率為0 . 3hz左右； ( 2 )地形對爆破地振動存在放大作用，研究剖面的坡面，水平向加速度及位移在地形相對高差45米左右最大，而后隨相對高差的增高而減小，相對高差為100米時，水平向位移及加速度絕對值均大于坡腳； ( 3 )強(qiáng)迫振動段，水平向加速度值隨時間變化的規(guī)律為：坡頂節(jié)點(diǎn)總的變化趨勢是越來越大，而坡體中部節(jié)點(diǎn)的變化趨勢是越來越小； ( 4 )當(dāng)爆破振速較小時，變形破壞的形式表現(xiàn)為坡頂表面滑塌型。
2. It's difficult to find explosion velocity in a sentence. 用explosion velocity造句挺難的
