in this context, the following parameters should be measured: specific gravity, bulk density, shear strength and grain size as well as the sediment depth of change from oxic to suboxic conditions.
为此应测量下列参数:比重、松密度、剪应力和颗粒大小,以及沉积物从充氧变化到低氧状态的深度。
288. sediment properties, such as clay percentage, liquid limit, plastic limit, plasticity index, activity, specific gravity solids and clay mineralogical composition were studied.
288. 研究了沉积物属性,如粘粒百分比、液限、塑限、塑性指数、活动、比重固体和粘粒矿物成分。
in the drop tests for liquids, when another substance is used, its relative density (specific gravity) and viscosity should be similar to those of the substance to be transported.
在液体的跌落试验中,在使用其他物质时,其相对密度(比重)和粘度,应接近于拟运输的物质。
in this context, the following parameters should be measured: specific gravity, bulk density, shear strength and grain size, as well as the sediment depth of change from oxic to suboxic, or suboxic to oxic, conditions.
为此应测量下列参数:比重、总密度、剪切强度和粒度大小,以及从氧化到亚氧化状态或亚氧化到氧化的沉积物深度。
the sediment should be sampled by at least four stations and measured for water content, specific gravity, bulk density, shear strength and grain size as well as the sediment depth of change from oxic to sub-oxic conditions.
沉积至少应从四个站点取样,并测量其含水量、比重、松密度、剪应力和颗粒大小,以及沉积从充氧变化到低氧状态的深度。
metals having a specific gravity (i.e., weight in comparison to weight of an equal volume of water) of 5.0 or over, and generally toxic in relatively low concentrations to plant and animal life.
比重(即与同等体积水相比的重量) 为5.0或以上的金属,并且相对较低的浓度一般就对植物和动物生命具有危害。
