【摘要】 束缚水的密度>lgcm-3,而且在饱和水和毛管水中不能忽略束缚水占有的重量。1g最大束缚水占据的平均体积≈0.776cm3。因此,饱和水的克数不能视为毫升数,最大毛管水的克数也不能视为毫升数。如果把该克数视为毫升数,那么总孔隙度和毛管孔隙度的测定将有不可接受的误差,而且测定结果高于真值。更多还原

【Abstract】 The density of bound water > 1g cm^-3,and the weight occupied by the bound water cannot be neglected in saturated water and capillary water. The mean volume occupied by l gram of maximum bound water is about 0.776cm^-3. Therefore, the grams of saturated water cannot be regarded as the cubic centimeters, and neither can the grams of maximum capillary water be regarded as the cubic centimeters. If the grams are regarded as the cubic centimeters, then the determination of total porosity and capillary porosity will have an unacceptable error ,and the determination results are higher than the true values.更多还原
