Testing method for water absorption, bulk density, apparent specific gravity and apparent porosity of fired whiteware products observation hole 陶瓷吸水性、毛体积比重、表观比重、表观气孔率测定方法(窑炉)观察孔,看火孔
Production practice on casting the round tube blank of steel 20 with round tube blank continuous caster testing method for bulk specific gravity of light weight castable refractories ( method for molded goods) 圆坯连铸机浇铸20钢铸坯的生产实践轻量型可浇灌耐火材料毛体积比重试验方法(铸型制品试验法)
Testing method for bulk specific gravity of light weight castable refractories ( method for molded goods) 轻量型可浇灌耐火材料毛体积比重试验方法(铸型制品试验法)
The soil bulk density and specific gravity increased and porosity of wetland soil reduced in O and A soil layers after fire. 火烧后小叶章湿地土壤草根层和腐殖质层容重和比重增加,孔隙度下降,土壤潜育层变化不大;
The lessen of the input and strength of the decomposition rate of SOM resulted in the accretion of soil bulk capacity and specific gravity, its changing trend was similar to the changing of the soil organic carbon ( SOC) loss. 土壤有机质输入量的减少及分解作用加强导致土壤持水量降低,其变化趋势与土壤有机碳损失趋势相一致。
Soil texture, moisture, bulk specific gravity, ground temperature and irrigation water temperature are the major factors which influence the infiltration capacities of frozen soils. 土壤质地、容重、含水量、地温和灌溉水温是影响冻融土壤水分入渗的主要因素。
According to the analytical result, test method and average specific gravity from bulk specific gravity and apparent specific gravity of aggregate were recommended to calculate the theoretical specific gravity. 根据分析结果,推荐用实测法或毛视平均密度法确定理论密度。
