請幫我校正有關噪音的英文。

we demonstrate that it is possible to improve the sound attenuation obtained from a mass of trees by arranging them in a periodic lattice.

他們證明了從一集中樹裡透過在一個週期性的格子裡可能改善噪音衰減。

we present experimental results which show that a belt of trees organised in a periodic array produces peaks of attenuation at low frequencies (fo500 Hz) not as a consequence of the ground effect but as a result of the destructive interference of the scattered waves.

我們實驗結果顯示樹的傳送帶在一週期性排列內產生衰減在低頻(fo500赫茲)的高峰 不是由於地面影響而是由於被散佈的波干擾破壞。

Moreover, the results reveal that with this type of arrangement we get more attenuation than with classic tree belts using less width, and that therefore these not extensive periodic arrays of trees can be used as green acoustic screens. 而且, 結果顯示使用較少寬度的優秀樹帶相比較,用這類安排我們得到更多的衰減, 並且這些不廣泛的規律樹能被用作為綠色音響屏幕。

    we demonstrate that it is possible to improve the sound attenuation obtained from a mass of trees by arranging them in a periodic lattice.

    我們證明了﹐藉著將相當數量的樹木以特定間隔週期做格子狀排列以改進對聲音的衰減是可能的。

    we present experimental results which show that a belt of trees organised in a periodic array produces peaks of attenuation at low frequencies (f<500 Hz) not as a consequence of the ground effect but as a result of the destructive interference of the scattered waves.

    我們提供的實驗結果顯示﹐依特定間隔週期排列的帶狀樹林對小於500赫茲的低頻聲波產生最大衰減的結果並非來自地面效應﹐而是對分散波的破壞性干擾所造成。

    Moreover, the results reveal that with this type of arrangement we get more attenuation than with classic tree belts using less width, and that therefore these not extensive periodic arrays of trees can be used as green acoustic screens.

    此外﹐本實驗結果還揭示﹕這種形態的排列要比傳統上較為狹窄的帶狀樹林具有更好的衰減效果﹔所以我們這種非寬廣間隔週期的樹木排列可以做為綠色的隔音屏障。

    註﹕此處的“periodic”雖翻成“週期性”﹐但在本文中不是指時間的週期而是樹木種植間距的週期﹔比方說("1"代表樹木﹐"-"代表種植間距單位)﹕1---1---1---1---1---.....; 1-1--1---1----1-1--1---1----1...; 1-1---1--1----1--1---1-1---1--1----1--1---1-1....等等﹐凡能“週而復始”的排列都屬於“週期”的性質。
