举几个例子，1）分子量，由于水泥样品中含有大量的纳米孔隙，若有机溶剂的

To give a few examples, 1) Molecular weight. Since cement samples contain a large number of nanopores, if the molecular weight of the organic solvent is too large and exceeds water molecules, it may not enter the gel pores and interlayer pores.

To give a few examples, 1) molecular weight, because the cement sample contains a large number of nano-pores, if the molecular weight of organic solvents is too large, more than water molecules, it is likely to be unable to enter the gel hole and inter-layer holes.

For example, 1) molecular weight, because the cement sample contains a large number of nano pores, if the molecular weight of organic solvents is too large, it will probably not be able to enter the gel pores and interlaminar pores.
