Due to the extent of ground disturbance in warfare during World War I, corn
poppies bloomed in between the trench lines and no man's lands on the
Western front. They were immortalized in the poem In Flanders Fields by
Canadian poet and soldier Lt Col John McCrae. Similarly, it is a symbol of
the blood of Polish soldiers killed in the Battle of Monte Cassino in the
Polish war song Czerwone maki na Monte Cassino (Red Poppies on Monte Cassino

上面的三个概念,因为这是我的专业,所以我来给大家说说。这第一个概念叫做
elastic vs. plastic;第二个概念叫做creep;第三个概念叫做ductile to brittle
transition。
先说第一个概念 elastic vs. plastic。弹簧在其设计的弹性范围之内的伸缩都应属于
elastic区域,也就是说是不会有永久的形变导致弹簧失效的。而如果你在三十发的弹
匣里压了三十一发或者故意把弹簧拉长一节,那就会导致plastic deformation,也就
是弹簧的长度会有永久性的变化,这时候弹簧可能就会有不给力的情况了。
第二个概念creep是指的弹簧在长期受力情况下tensile stress和yield stress都会慢
慢变小,也就是说plastic deformation会提早发生。可是注意一点,假如是在室温情
