With ILO-92 Otodynamics Analyzer,distortion product otoacoustic emissionsat the 2 f1-f2 frequency were recorded from 86 normally hearing ears in response to four groups of different primary levels (L1=L2=75 dB SPL ; L1=L2=65 dB SPL ; L1=L2=60 dB SPL ; L1=65 dB SPL , L2=50 dB SPL).The average DPOAEs-gram demonstrated a bilobed contour with two peaks at approximately 1.5 kHz and 5 kHz and a "notch" between 2.5 kHz and 3 kHz.Moreover,the contour of DPOAEs-gram had no obvious changes with sex,ear or primary stimulus levels differences.

The spectrum peaks nearby 530nm and 480 nm are corresponding with BTSD and BMD respectively. It is found from measurement that the luminescence peak from BMD is bluely shifted. The atoms of BTSD nearby dislocation core are affected by tensile stress along the Burger's vector direction leading to its band gap narrowed. In addition, there is the effect of part quantity of edge dislocation in BMD existed. Part of atoms in BMD are strained by compressive stress leading to its band gap narrowed, in other words, the wavelength from BMD is shorter than that from BTSD.

从测试结果中还发现BMD 的发光位较BTSD有所蓝移，分析认为BTSD位错芯附近原子沿伯格斯矢量方向只受到拉应力，致使禁带宽度变窄，BMD由于除了具有螺型位错的分量外还具有部分刃型位错的分量，而刃型位错中有部分原子受到压应力的作用，导致禁带宽度增宽，从而使得BMD的发光波长比BTSD短
