A lot of vector fields are not gradients.───很多向量场都不是梯度。
But in 2d cell cultures, such gradients aren't present.───但在2d的细胞培养基中，这样的梯度就不存在了。
The key with gradients is not to overdo them.───运用渐变的关键是不要做得太过了。
A teat-bed is set up to measure the surface velocity of ethyl alcohol layer at different temperature gradients of the wall.───通过对无水乙醇进行的实验测定，测得了液膜表面流动速度与液膜温度梯度之间的关系。
New tools have been used to reveal the basis of cell polarity, morphogen gradients and regulation of signaling in developing animals.───新的工具已被用来揭示了基础细胞极性，形态梯度和调节信号在发展中国家的动物。
During a fault, the flow of current to earth will result in voltage gradients on the surface within and around a substation.───在故障期间，电流流入地中时会在变电站内及周围地面上形成电位梯度。
Some of these make logical sense, in terms of different temperature gradients.───不同的温度梯度或许可以部分解释这种多样性。
Several tests can be taken along a board in less than a minute to alsodisclose any gradients or wet streaks.───几个木板测试可以在不到一分钟内完成并显示其变化或湿度变化倾向。
Just as water will run downhill, so heat, if left to itself, flows down the temperature 'hill' (gradients).───就象水总是流下山一样，热（若听其自然）也是沿“热坡而下”。
With regard to the gradients, Leathart must have had in mind the steep section of the Deep Level.
The effect of these gradients s to cause the nuclear magnetic resonance signal to form a series of spin echoes.
He widened it, evened out the gradients and put in sweeping curves.
Palaeoclimate reconstructions indicate that the meridional temperature gradients decrease, and poleward heat flow increases, as global mean temperature increases.
It may be wondered if gradients in some chemical might guide cells to their destination.
We found striking gradients in both short and long spells of sickness absence, with higher rates among employees with lower status.
The similarity between the Carboniferous maturity-depth gradients for these two areas is therefore not surprising.
Such effects owe their origin to gradients in the field and are called tidal effects.
There were some steep gradients, particularly Anerley Hill, leading up the Crystal Palace.
