Therefore, in this research we attempt to use the mean value and a linear interplant to modify the threshold. By using this method, many meaningful results as well as the absolute threshold are conserved.

有鉴於此，本研究尝试利用算数平均数的原理并配合线性内插公式订定门槛値，这个方法不但具有相对门槛値的意义且节省电脑运算时间，同时也具备绝对门槛値之意义。

The image is first reduced in dimension by Gaussian pyramid, and the Hu moment is applied to the fixed sized overlapping blocks of low-frequency image. The eigenvectors are lexicographically sorted. Then, similar eigenvectors are matched by a certain threshold value. Finally, the area threshold value is proposed to remove the wrong similar blocks. The mathematical morphology operations are performed to locate the tampered part.

该算法首先将图像进行高斯金字塔分解，将低频图像进行块分解，提取每块的Hu矩不变特征，并将特征向量排序，然后为每个特征向量搜索符合阈值的相似特征向量；最后利用区域面积阈值去除错误的相似块，并结合数学形态学定位篡改区域。

Therefore, with considering threshold pressure gradients and the maldistribution of threshold pressure gradients caused by reservoir heterogeneity, it will be more objective and better to forecast the production performance of gas wells and guide low-permeability gas reservoirs practical production.

因此，考虑启动压力梯度和由储层非均质性引起的启动压力梯度非均匀分布能更为客观的预测气井单井生产动态，为气田合理开发提供可靠的决策依据。

Results The patients were predominently female teenagers with a history of gradual onset of bilateral hearing loss, pure tone audiometry revealed symmetric ascending audiograms with moderate hearing loss at frequencies below 1 kHz, but relatively normal hearing at 2 kHz and above. Speech reception thresholds were between 40 to 85 dB HL, discrimination score was from 29% to 68%. Stapedial reflex, auditory brainstem response and compound action potentials were absent or threshold elevated disproportionately to the pure tone threshold. All of the patients had normal cochlear microphonics and robust spontaneously and transiently evoked otoacoustic emissions, the TEOAE showed no contralateral suppression effects as seen in normal subjects.
