weak dimension

The study shows that salt-water change in field dimension of soda saline soil have the following features: high-spatial variation of salt content, exist of both saline and alkaline, poor hydraulic characteristic, and weak in transfer between soil water and groundwater.

研究表明田块尺度苏打盐渍土水盐变化具有如下特征：土壤盐分含量高度空间变异性、盐化和碱化共存，水力性质极差，土壤水和地下水的转化关系非常微弱。

The Dimension of the Strong and Weak Variation of Generalized Brownian Sheet

广义布朗单的强变差与弱变差的维数

To separate a weak deterministic signal from a chaotic background of which the dynamic mechanism is unknown is a different problem from the noise reduction for a chaotic signal since the mixed signal is also a chaotic signal with higher dimension than the original chaotic system.

混沌信号与确定性小信号叠加生成的混合信号是一更高维的混沌信号，因而不能用一般的混沌信号噪声抑制的方法进行分离。
