1.The material has a high plasticity number, which means it can easily be deformed.
这种材料具有高塑性指数，意味着它很容易变形。
-
2. In engineering, the plasticity number is used to determine how much stress can be applied before the material fails.
在工程中，塑性指数用于确定在材料失效之前可以施加多少应力。
-
3.The engineers found that increasing the temperature could increase the plasticity number, indicating that the material was more flexible at higher temperatures.
工程师们发现，提高温度可以提高塑性指数，这意味着材料在较高的温度下更加柔软。
