本实验中，25%被选用作为含水率是因为25%含水率被一系列预实验证明能

In this experiment, 25% was selected as the moisture content because 25% moisture content was proved by a series of pre-experiments to achieve better experimental results; and the selection of moisture content in clay experiments in the papers of scholars such as Peng and Shen was also For reference, for example, clay with a water content of about 19% is selected by Peng, and clay with a water content of 21% is selected by Shen.

In this experiment, 25% was selected as water content because 25% water content was proved to achieve better experimental results by a series of pre-experiments, and Peng, Shen and other scholars' papers on the selection of water content in clay experiments were also referenced, for example: about 19% water content of clay selected by Peng, 21% water content of clay was selected by Shen.
