在此研究中，本實驗室建構一套精密之超聲波速度與衰減之量測系統，研究攙雜α-alanine 之 triglycine sulphate 晶體 (α-alanine-TGS) 在室溫及相變區之超聲波速度與衰減，將結果與無摻雜之 triglycine sulphate 晶體比較，發現有相異之處，其相異行為與參考文獻中之理論預測符合。接著我們將α-alanine-TGS 暴露在紫外線照射下達一定的能量密度，我們發現，相變區之超聲波衰減以及相變溫度沒有因紫外線輻射而有顯著改變，相變時超聲波速度陡升之高度亦無顯著的變化趨勢，表示本研究所用之紫外線能量密度到達9379(J/cm^2)時對以上這些特性不造成影響，然而發生超聲波速度陡升的溫度範圍隨著能量密度的增加而增加，此與參考文獻中γ射線造成晶體中的缺陷，而使相變現象改變之情形相似。

In our work, we constructed an ultrasonic system for studying the lattice structure of materials. We measured the velocity and the attenuation of ultrasound in α-alanine doped triglycine sulphate (shortly α-alanine-TGS) in the room temperature region and in the phase transition region. We found notable differences between the behavior of α-alanine-TGS and pure TGS, and they conform to the cited references. After applying ultraviolet irradiation, we measured the velocity and the attenuation of ultrasound in α-alanine-TGS in the phase transition region. The attenuation anomaly with respect to the temperature was without change, and the change of the magnitude of the velocity anomaly had no particular tendency. The phase transition temperature Tc of α-alanine-TGS crystal was not affected when the ultraviolet energy density reached 9379 (J/cm^2). We found that the width of the velocity anomaly increases with the irradiation energy density. This phenomenon is similar to the case of ferroelectrics being exposed to γ-irradiation.
