塑料资料机械功能中DRY/COND是什么意思？
DRY是英文单词，枯燥的意思，COND就是湿润的。
这两个词普通出如今尼龙塑料的物性表当中，在该表中枯燥条件下的强度会高一些，然而在COND条件下韧性会好一些。

MECHANICAL PROPERTIES OF METALS金属的机械功能 Mechanical properties are the characteristic responses of a material to applied forces. These properties fall into five broad categories: strength, hardness, elasticity, ductility, and toughness. 金属的机械功能是金属遭到外力作用时所体现进去的特色。
这些功能关键分为五类：强度，硬度，弹性，塑性，韧性。
Strength is the ability of a metal to resist applied forces. 强度是金属接受外加力的才干。
Strength properties are commonly referred to as tensile strength, bending strength, compressive strength, torsional strength, shear strength and fatigue strength. 强度功能普通触及到抗张强度，笔挺强度，耐压强度，抗扭强度，切变强度和疲劳强度。
Tensile strength is that property which resists forces acting to pull the metal apart. It is one of the most important factors in the evaluation of a metal. 抗张强度是金属抵制被分别的才干（功能）。
是评估金属的关键起因之一。
Compressive strength is the ability of a material to resist being crushed. Compression is the opposite of tension with respect to the direction of the applied load. Most metals have high tensile strength and high compressive strength. However, brittle materials such as cast iron have high compressive strength but only a moderate tensile strength. 耐压强度是金属抵制被压碎的才干（功能）。
压力是张力的反方向外加负载。
大局部金属具备较高的抗张强度和较高的耐压强度。
然而，像铸铁这种脆金属虽有较高的耐压强度，却只要较中等的抗张强度。
Bending strength is that quality which resists forces from causing a member to bend or deflect in the direction in which the load is applied. Actually a bending stress is a combination of tensile and compressive stresses. 笔挺强度是金属抵制所受负载方向的笔挺和歪斜的才干（功能）。
实践上笔挺应力是压力和张力的综合。
Torsional strength is the ability of a metal to withstand forces that cause a member to twist.抗扭强度是金属抵制被改动的才干（功能）
