Both the data of nature earthquakes and experiments in laboratory show that the relation between magnitude and logarithm of frequency is not a rigid straight line.

天然地震资料和实验室资料均表明，震级与频度对数之间的关系不是一条严格的直线。

Experiment results showed that the relation between exciting voltage and induced velocity magnitude was linear, but the influence of supply frequency was not evident.

实验结果表明，等离子体激励作用主要集中在近壁面附近；激励电压与诱导速度近似为线性关系，激励频率对诱导速度的影响不大。

The G-R relation between the earthquake magnitude and frequency has been an important premise in seismological study, but its actual distribution often deviates from its theoretic result.

地震震级频度的古登堡·里克特关系式(简称g - R关系式)一直是许多地震学问题研究的重要前提之一，然而实际分布常常与这一关系式有一定的偏离。
