The observed clinal variation in the frequency of serotinous cones may be described as a fairly regular decrease in all directions . 所观察到的晚熟球果的频率梯度变异可描述如下：向四周相当有规律地渐次减少。
A number of overall correlations have been developed for the prediction of the pressure gradient in the vertical flow of gas-liquid mixtures . 为了预测气液混合物垂直流动的压力梯度，已经得出了许多整体相关规律。
Even if the pressure gradient is partly balanced by the fluid acceleration, its order of magnitude is usually no larger than the hydrostatic gradient . 即使压强梯度部分地被流体加速度平衡，其数量级通常也不大于静压梯度。
Measuring the differences emphasizes anomalies from shallow sources having steep gradients at the expense of low-gradient variation of the type . 测定两点之间临近的差只需以牺牲低梯度变化为代价而突出浅层源引起的具有陡梯的异常。
Differential rates resulting from temperature gradients in the material introduce stresses which can't be removed by later heat treatment . 由材料内部的温度梯度引起的速度差将导致产生应力，这种应力是无法用以后的热处理来消除的。
We may assume that there is no correlation between the local velocity of a liquid particle at a mathematical point inside the void space and the concentration gradient . 我们可以假定，在空隙空间的一个数学点上液体质点的局部速度和浓度梯度之间无相关性。
