最值得注意的是，包含顺磁性物质的普通硅酸盐水泥是不应该应用在低场核磁共

The most notable thing is that ordinary Portland cement containing paramagnetic substances should not be used in low-field nuclear magnetic resonance studies, because the paramagnetic substances in them will change the position and intensity of the relaxation spectrum, so the author should not Have you compared the effects of white cement and ordinary Portland cement on the results?

Most notably, ordinary silicate cement containing a flux magnetic substance should not be used in low-field MRI studies, because the flugic substances in it change the position and strength of the relaxation spectrum, so did the authors compare the effects of white cement and ordinary silicate cement on the results before the study?

It should be noted that ordinary portland cement containing paramagnetic materials should not be used in the study of low field nuclear magnetic resonance, because the paramagnetic materials will change the position and strength of the relaxation spectrum. Therefore, did the author compare the influence of white cement and ordinary silicate cement on the results before the study?
