請幫我看看這篇關於噪音跟樹的文章

由於對物理這方面的知識不足.希望有那位先進可以把翻譯錯誤的地方糾正出來.謝謝幫忙唷。

The measurements were made at the end of winter and at times when background noise and wind levels were weak enough to have no effect on them. 在冬天末測量和有時被當做背景噪音和風水平,微弱得足以對他們沒有影響時。

The sound attenuation depends on the direction from which the sound impinges on the sample, thus we measured two different directions of the k wave vector, 0 and a degrees for the two-dimensional arrays, changing the position of the source and the microphones.噪音衰減取決於聲音碰擊這個樣品, 因此我們測量k波矢量的兩個不同的方向, 為二維的陣列的0和一度,改變來源和話筒的位置。

The values 0 and a degrees correspond to two of the high symmetry directions of each array analysed.這兩個中符合0和一度數標準,分析每個陣列的高對稱方位

The sound attenuation is obtained over a range of frequencies that depends on the lattice constant of the array (p and a), and is given by Bragg's law for diffraction [12].: 獲得噪音衰減取決於陣列(p和a)的點陣常數的頻率範圍內,並且用於布拉格的法規為折射 [12].

原來我翻的沒問題唷~

不然怎麼都沒改~ㄏㄏ

    The measurements were made at the end of winter and at times when background noise and wind levels were weak enough to have no effect on them.

    測量都在冬季尾聲﹐每當風速與噪音背景值弱到不足以影響測量正確性的時候才進行。

    The sound attenuation depends on the direction from which the sound impinges on the sample, thus we measured two different directions of the k wave vector, 0 and a degrees for the two-dimensional arrays, changing the position of the source and the microphones.

    噪音衰減取決於聲音從那個方向碰擊樣品, 因此我們藉著改變聲源與麥克風的位置﹐從二維陣列的“0”及“a”度的兩種不同方向來測量k波的矢量。

    The values 0 and a degrees correspond to two of the high symmetry directions of each array analysed.

    此“0”與“a”度是對應到每個受分析陣列所有高度對稱方向的其中兩個。

    The sound attenuation is obtained over a range of frequencies that depends on the lattice constant of the array (p and a), and is given by Bragg's law for diffraction [12].

    在某一頻率範圍上獲得了噪音衰減成果﹐此頻率範圍取決於陣列p與a的格子常數﹐而且是Bragg的繞射法則所給予。
