测试结果表明：Si3N4薄膜的热导率随温度的升高而增大；高频段下，热导率受频率影响大，误差大；在低频段下薄膜热导率与频率变化基本无关；基于电子与声子的局部热平衡运输方程假设，S i3N4薄膜的热导率具有极度非平衡性；通过比较电阻、热导率与温度的关系可以看出加热器的尺寸大小会影响薄膜的热导率，最佳加热器的宽度选用20μm左右。

Improvement of MT migration tomography technology Based on the immanent relationship between tomography purpose and suitable frequency segment selection, we raise an entire frequency segment multi-parameter tomography scheme of MT finite difference migration. We establish a mathematical relationship among apparent electromagnetism reflectance, migration reflectance, background resistivity and the true resistivity distribution. After the introduction of TE/TM mode superpose rate, we carry out the associated resistivity tomography of two polarization mode to adapt the practical data interpolating situation.

If it is so easy to economise on spectrum, Mr Mittal says, then perhaps the government's own phone companies, BSNL and MTNL, would like to surrender some of their spare capacity and show the rest of the industry how to make do with so little.
Mittal先生表示，如果政府觉得解决频段问题很简单的话，政府可以让政府自己的电信公司BSNL和MTNL试一试，他们可以交出多余的频段，然后让大家看看能不能用很少的频段解决问题。

The main peaks of the EEG power spectra were in delta and theta frequency range. In the stage of ethanol exposure, the rats exhibited much more act of attack than the control, the alpha waves of EEG decreased, while the delta waves increased. The EEG power spectra analysis showed the delta power increased and the theta power decreased. In the stage of ethanol withdrawal, the rats showed some withdrawal behaviors such as wet dog shakes, sniffing, groomingand tonic-clonic seizures for audiogenic stimulus. Spikes and spike-slow waves were found in the EEG. In power spectra analysis, the delta power decreased while the alpha and the theta power increased, the EEG frequency band moved to the high-frequency rang. These changes were found obviously on the sixth day and disappeared on the 1 Oth day after the ethanol was removed.
