Objective to analyze the clinical value of peak myocardial velocity gradient (MVG) as a noninvasive indicator of left ventricular (LV) systolic or diastolic function.
目的探讨心肌速率阶差m VG评价左室舒缩功能的价值。
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。
