amplitude of annual variation

From this model section, a formula is obtained for calculating the amplitude of relative apparent annual variation of resistivity at a station characterized by two resistivity layers.

从此观点出发，导出以二层电性剖面为特征的台站正常地电阻率相对似年变化幅度公式。

It is also analyzed that amplitude and phase changes of annual term in mean sea level variation with latitude.

进一步分析了海平面上升速率及周年项振幅和相位随纬度变化情况。

Different ways of stabilizing the outside temperature were employed. A slow periodic annual variation of its readings was observed with amplitude of about 500 microgals.

使用不同恒温条件，发现以一年为周期的缓慢变化，幅度可达500微伽。
