You can make the blade from a spring leaf from an old Ford.

你可以用一辆旧福特牌汽车上的钢板做矛头。

Two or three locking screws are placed specifically at the ends of the plate. This 'spring leaf' like construct allows micro-motion at the fracture site.

在钢板末端固定两个或三个锁定螺钉，这种类似“跨越的钢片”的结构允许骨折部位产生微动。

By the variational method, the governing equation of the plate non-linear theory is solved, and he relationship between load and deformation of a single spring leaf is obtained.

应用薄板非线性理论的变分方法求解基本方程，得到了单片碟形弹簧的载荷和变形关系以及应力分布及其计算公式。

In Europe, for instance, spring flowerings in 2000 occurred about 8 days earlier than they did in 1971 on average, and autumn events, such as changes in leaf colour, about 3 days earlier.

例如在欧洲，2000年春季开花的时间比1971年平均开花时间早8天，而在秋天，植物的变化如叶子变色等，则早了3天。

The trees come into leaf in spring.

春天，树木吐芽长叶。
