负偏差,英文名称叫negativedeviation,负偏差是当溶液的蒸气压小于具有相同组成的理想溶液的蒸气压时的现象。产生的原因是由于溶液中不同组分分子间的相互作用较纯物质的分子间相互作用为强,或由于在不同组分分子间互相缔合,因而使分子从溶液中逸出的能力降低。
钢材产品实行负偏差轧制是企业提高经济效益的有效措施。
The minus tolerance rolling of steel products is an effective measure for increasing enterprises profit.
当声波是空间位置和时间的周期函数时,平面波误差项永远是一负偏差项。
The plane wave error is always negative windage, when the sound wave is the cycle function of space and time.
而从具有最低恒沸点的混合溶剂中吸附溶质时,吸附量与溶剂组成的关系与直线呈负偏差。
From constant boiling mixtures with a minimum, the adsorption of solutes also varies with the composition of mixed solvents, but a negative deviation is observed.
