gas by-passing 中文意思是什麼
gas by-passing
解釋
天然氣竄流-
As explained by the following figure, gas in low pressure and low density will alter the light that passes through it. it is because the gas will absorb light at some particular wavelengths and re - radiate it in random directions. thus, after passing through the low pressure gas, the spectrum of the original white light will have dark lines, called
並不是所有光譜都是黑體輻射光譜，如下圖所示，低壓下的低密度氣體會改變通過它們的光線，這是由於氣體會吸收特定波長的光波並隨機向不同方向把所吸收的光線輻射出來，結果光線在通過低壓氣體后，原本的光譜上會出現很多稱為 -
Pulses of radiation are emitted when free electrons in the gas are accelerated by passing ions.
當氣體中的自由電子被掠過的離子加速時，將發出輻射脈沖。 -
The former one is a product of the pressure pulsation resulting from the fan blade periodically cutting the air, with the blade passing frequency as its base frequency and accompanied by higher harmonics. the wide - band turbulent noise is formed when the rotating fan forces the surrounding air to produce turbulent throw - outs and results in gas thickening and thinning processes
旋轉噪聲是由於風扇的葉片周期性地切割空氣，引起空氣的壓力脈動產生的，以葉片通過頻率為基頻，並伴有高次諧波。湍流噪聲是由於風扇運動導致的周圍空氣發生湍流脫體，使空氣發生擾動，形成氣體的壓縮與稀疏過程而形成的，是一個寬頻帶噪聲。
