Results: compared with the control group, the amplitude and conduction velocity of biphasic action potential were gradually and significantly reduced in the hyperosmotic dextroglucose sub groups (concentrations at 20% and 40%), hyperosmotic mannitol sub group (concentration at 20%) and hyperosmotic sorbitol sub groups (concentrations at 20% and 40%) in a time dependent manner.

结果：与对照组比较，20%、40%葡萄糖组，20%甘露醇组和20%、40%山梨醇组的动作电位幅度有显著降低，传导速度有显著减慢，呈时间依赖关系；10%葡萄糖组、10%甘露醇组和10%山梨醇组高渗溶液均可使蛙坐骨神经干动作电位幅值有不同程度上升，传导速度略微减慢。

The resonant frequency fr was found to be indepen-dent of Am in the measured amplitude range. We considerthat the variation of fr with Ba is mainly contributed bythe diamagnetism of the specimen, and the motion of fluxlines in the specimen plays only a role of perturbation.

共振频率〓在振幅测量范围内未发现振幅效应，认为〓随磁场的变化主要是由于材料的抗磁性的贡献，内部的磁通线运动只起着一种微扰的作用。

The diffraction efficiency of a phase grating is compared with that of an amplitude grating with same grating constant.

引 言基于多普勒效应的激光测速、测振技术是 60年代初从流体测速研究发展起来的[1] 。

Most electroencephalogram appeared no main rhythm,middle or high amplitudeθ,δwave diffusibility.

患者脑电大部分表现为无为主节律，中高幅θ、δ波增多的弥散性慢活动。

The dioptric equivalent of the near point of emmetropiais the amplitude of accommodation.

1正视眼近点的等效焦度称为调节幅度。

We also study the CP-violating asymmetry in nonleptonic decay Λ→ pπ. By employing the Skyrme model to calculate this decay amplitude contributed by the gluonic diploe operator, we find a possible large CP-violating asymmetry could be expected, which is consistent with the previous study.

在计算supersymmetricextensions of the standard model中Λ→pπ衰变过程中CP破坏不对称性时，我们使用了Skyrme模型计算了其中关于强子振幅部分，结果显示相对于标准模型的预言有较大的放大效果，这个结果和前人研究结果一致。

Chronic stress could induce disaccord of time to peak value of PS amplitude with EPSP slope.

慢性应激引起PS幅值和EPSP斜率峰值时间不同步，表现为PS幅值达到峰值时间较EPSP斜率提前。

The traditional analog frequency-sweeping instrument, which mostly uses the LC circuit as the frequency oscillator, is more expensive, too much bigger and heavy to carry. It can only display the curve of amplitude-frequency, but can't used to measure the phase-frequency, and can't used to print the curve of frequency response characteristic either. It brings many discommodity to the user.

传统的模拟式扫频仪大多是用LC电路构成扫频振荡器，它不仅价格昂贵，体积庞大，而且只能显示幅频特性曲线，不能得到相频特性曲线，更不能打印被测网络的频响曲线，给使用者带来诸多不便。
