While we were trying to understand the origin of subcontinental mantle anisotropy by SKS splitting measurements in Qinghai-Xizang plateau, we were perplexed for answers to the following questions:(1) why the inefficient Sn propagation region correlates with the large delay time (1.91-2.40s) of SKS splitting,(2) why very strong δt variations occur at the edges of this region, and (3) what results in the abnormal delay time.

当人们试图解释青藏高原异常的剪切波分裂成因时，以下的问题让人们感到困惑：为什么异常大的SKS分裂延时(1.91-2.4s)出现在青藏高原北部Sn波缺失区；(2)为什么分裂延时突变（1.47s和1.09s）出现在Sn波缺失区的边缘；(3)为什么快波极化方向与地表大规模的构造走向之间存在约20°-30°的偏差。

Intracellular pH change did not influence the actions of ketamine while superfusion of NMDA .

在pH 6.81的人工脑脊液中，ketamine抑制放电频率增快的药效减弱了35 %，在pH 8.1的人工脑脊液中，ketamine抑制去极化的药效减少了29 %，而胞内酸化或碱化则不影响ketamine拮抗NMDA的药效。

Ethanol inhibition was not affected by 5 nM and 20 nM calyculin A (a phosphatase 1/2A inhibitor). Prior superfusion of 5 nM and 20 nM KT5720 also attenuated ethanol inhibition of NMDA-mediated depolarization. 1 μM and 3 μM chelerythrine, a selective protein kinase C inhibitor or 20 nM calyculin A did not affect ethanol inhibition of NMDA-induced response.

当以表面灌流方式，事先给予5 nM或20 nM KT5720时，同样可以减少乙醇抑制NMDA引发的去极化作用；分别给予1 μM或3 μM chelerythrine或20 nM calyculin A则不会影响乙醇抑制NMDA所引发的反应。

The increasing firing rate and depolarization of LC neurons produced by superfusion of 10嵱 NMDA was decreased by 91.7 % and 89.0 % when pre- superfusion of 100 嵱 ketamine.

我们灌流10 microM NMDA，结果造成蓝斑核神经元的放电频率增加约430.0 %，去极化约11.8 mV。

In the first part of this study, the nonlinear optical susceptibilities, which includes three topics, are studied.
