The two-parameter MVG model yields the largest errors among the five models, and therefore is not suitable for describing soil particle-size distributions in Fengqiu area.
在这五种参数模型中，MVG模型的误差最大，不能精确描述封丘地区壤土类土壤的颗粒大小分布。

Conclusion MVG is more sensitive than myocardial velocity for detecting ischemic myocardium.
结论M VG是比心肌运动速度更敏感的反映局部心肌缺血的指标。
