dens = dens(变浓厚) = 变浓厚→稠密的
condensation = con(全部) + dens(变浓厚) + ation(表名词) = 全部结起来变厚→凝结
accreditation = ac(加强) + cred(相信) + ity(表性质) + ate(表动词) = 加强信用→委派
acidity = acid(酸) + ity(表性质) = 酸的性质→酸性
稠密,密度
density
常考释义
Its mass is only one-third as great, which means its density must be only one-third as great as well.
但它的质量仅为水星的三分之一,这也意味着它的密度应该也只有水星的三分之一。
