As an example, the global displacement and stress fields are computed for the Preliminary Reference Earth Model (PREM) proposed and suggested by IGS and IUGG in 1981. The distributions of displacement and stress within the earth are plotted.

• 作为例子,文中对1981年IGS及IUGG公布并建议采用的“初步参考地球模型”(简称PREM模型)计算了引潮力引起的全球位移场及应力场,给出了模型地球的内部位移及应力的分布曲线。
