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。

We found that the microstructures and magnetic properties were not influenced with depositing temperature and sputtering power. The magnetic properties were only affected by Fe layer thickness. When the Fe layer thickness is thinner than 5 nm, weak exchange coupling raised between Fe cap layer and FePt recording layer. When the thickness reached 10 nm, the strongest exchange coupling formed. Film coercivity didn't distinctly vary as Fe layer thickness is thinner than 15 nm. Consequently, we measured DCD curves and had the same conclusions. Indeed, the appearance of exchange coupling is confirmed with 10 nm Fe cap layer.

我们并发现溅镀Fe之温度与瓦数，并不会对结构或是磁性质有显著的影响，Fe厚度的改变虽然也不会改变结构，但是对Cr/Pt/FePt/Fe磁性质却有明显的变化，当Fe厚度薄时(3、5 nm)，在Fe和FePt界面仅有弱的交换耦合力产生，Fe厚度是10 nm时，此时交换耦合力为最强，厚度再增加到15、20 nm时，Hc反而略为上升，同样的我们量测DCD曲线，也证实了Fe厚度10 nm的确有交换耦合力存在。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
