OBJECTIVE To compare the equivalence and safety between reference preparation and test preparation of alprostadil injection in patients with chronic lower extremity arterial occlusive disease.
目的本试验旨在观察种市售前列地尔注射液在治疗下肢慢性动脉闭塞症的等效性和安全性。
The Stepwise Equivalence t-Test can also be used to determine the safety of drugs used and to compare the drug effects, etc.
逐步等效性t检验也可用在确定仿制药的食用安全区间、比较药效等等。
Lastly, the relationship curve about mining safety and rock blasting can be got through applying Sadov's formula and the equivalence of blasting vibration velocity and acceleration.
最后，应用修正萨道夫斯基回归公式和爆破震动速度与加速度的等效性，求得矿山岩土液化程度与爆破用药量的关系曲线。
