The amount of fertilizer used in the exponentialexperiment was only 57% of that used in the traditional way.
同时，指数施肥方式肥料用量较少，仅占常规施肥的5 7% 。

In column experiment the salt release flux from different sediment can be expressed as a negative exponential function and decrease in the order of silty clay, medium-fine sand and pelitic silt.
静水实验中沉积物向上覆水体盐分释放通量符合负的幂指数形式，并按粉质粘土、中细砂、泥质粉砂顺序递减；

The result of this experiment reveals that the tangential modulus is exponential with axial stress, and varies with rock block size and rock property.
