Therefore, the variation of air temperature is not the main factor affecting the displacement of the slope.

因此，气温变化不是边坡位移起伏的主要因素。

The artificial "stone", a thin layer of translucent resin shaped to a wavy form, will float (hung by transparent wires) in the air, with spotlight on top to strengthen the variation of the thickness.

人造石的“水”悬浮于空中（以多根极细的鱼丝悬挂），半透明树脂的极薄片层呈现水波状，正上方的人工光照使地面呈现粼粼波光。

So, instead of having the periodic variation of water, or the periodic variation of air density here we're talking about an electric field.

不像水或者空气密度的,周期变化，我们这里,讨论的是电场。

An ideal one would keep the same rate regardless of variation in power supply, temperature, air pressure, magnetic fields, or any other disturbing influences.
