The space elevator is exactly what its name says it is: a long cable anchored at one end to the ground and at the other end high in space, protruding from the planet like a spoke in a rotating orange.
顾名思义，太空升降梯是一根很长的电缆固定在地面的一端，另一端高高地延伸到太空中，就像一条从旋转的橙子中伸出的辐条那样伸出地球。
We use this method to assign a long-form breed name to each enumeration value, which is what the Value.toString method returned in the output above.
我们使用这个方法来给每一个枚举值赋一个长的品种名称，也就是上面输出中的Value . toString方法所返回的值。
There are lots of flavors of this, but the basic idea is that you put a tag at the beginning of a variable name saying what type it is. (So all unsigned long variables begin with ul, etc.)
其种类很多，但基本的理念是在变量名的开始添加一个标记以表示其类型（例如，所有无符号长型变量都以 ul 开头）。
