Standard test method for volume weights , water - holding capacity , and air capacity of water - saturated peat materials 水饱和泥炭物质的容重吸水量和含气量的标准试验方法
In cold areas , concrete is always deteriorated by freezing and thawing cycle . the durability and the corrosion of concrete are directly affected by the water - saturated degree of concrete 寒冷地区冻融循环破坏往往是导致混凝土劣化的主要原因,而混凝土内部的水饱和程度又直接影响了混凝土本身的抗冻性和耐腐蚀性。
The charac teristics of homogenization temperature and salinity data also reports that this high - salinity inclusions were not generated by aqueous fluid immiscibility or boiling in ore - forming processes , but generated directly from a water - saturated crystallizing magmatic melt and that the main mechanism of ore deposition is the mixing of magmatic fluid and underwater not boiling of hydrothermal solution 均一温度和盐度特征还表明,高盐度包裹体不是由热水溶液的不混溶作用或沸腾作用形成的,而是由岩浆熔体直接分离的卤水形成的;沸腾作用对矿质沉淀的作用不大,而流体的混合作用是银山矿床矿质沉淀的主要机制。
Based on the results from both laboratory test and field application of vacuum preloading it can be concluded that soil is water - saturated in the processes of vacuum consolidation or vacuum preloading . thus , the consolidation properties in negative - pressure area cannot be calculated by using the theory based on non - saturation soil . negative pore - water pressure and suction were specified 在室内试验及现场试验基础上,证明真空预压加固地基过程中,负压区土体仍是饱和的,不能用非饱和土理论来计算负压区的固结性状,并辨析了负压与吸力的概念。
Using the rock resistivity meter with simulating in - situ conditions , the relations between rock resistivity and temperature were observed from 6 sandstone samples with different porosity and permeability , while samples were brine water - saturated and subjected to certain confining pressure . it is found that the resistivities of water - saturated rock samples decrease in the form of power expression with the temperature increase . although the resistivity of brine water decreases with temperature in the same rule , it can not entirely account for the decreasing of rock resistivity . the cementation factor 利用模拟地层条件岩芯电阻率测量仪,对6块孔隙度渗透率各不相同的砂岩岩芯,在一定围压条件下,岩芯完全饱和盐水时,考察了岩芯电阻率随温度的变化。发现饱和盐水岩芯的电阻率随温度升高,以幂函数形式下降。虽然岩芯中饱和盐水的电阻率同样随温度以幂函数形式下降,但岩芯电阻率的下降不能完全用岩芯饱和盐水的下降表征。
