The as-received material had an average grain size of 12µm determined by the linear intercept method.
According to the earlier work, an efficiency of 40% represents the DRX for low stacking fault energy materials like Mg alloys [4].
Ziegler [5] has shown ξ(ε& ) which, when negative, indicates microstructural instability in the material.

Because Shangyu-Longquan Sinian-Paleozoic uplift belt has special double bonanza layer overlay structure; for its lower part is the Fig. 1 Structure sketch map of xiachen-wangchangmu fluorite mine Chencai group basement metamorphic rocks series(Anzch) which have high-grade metallogenic material (F) ; its upper part is Mesozoic Jurassic Period(J3) volcanic rocks series and Cretaceous Period(K1-K2)volcanic sedimentary rocks series (J3-K/Anzch) which have high-grade metallogenic material (F); all of these determined that it is the fluorite ore enriched most favorable tectonics-formation environment[2].

Some teaching materials combine these two parts together[1] and others describe them separately in two parts [2] [3], but there are no substantial differences.
The USA started research on geo-environmental engineering earlier, and the famous Journal of the Soil Mechanics and Foundations Division of ASCE (American Society of Civil Engineers) was renamed the Journal of Geotechnical and Geo-environmental Engineering with the constant development of the subject of soil mechanics.
Soil mechanics is an experimental science.
