Consequently, under voluntary contributions, the only equilibrium park size is S0.

这样在自愿捐款条件下，公园的均衡面积为S0。

That is, for any park size smaller than S0, citizens will voluntarily contribute to make the park larger.

这样，对于任何小于s0的公园，居民将增加捐款以增大公园面积。

So, in Listing 6, step S0 is executed followed by steps S1 through S4, which are executed simultaneously.

所以，在清单6中，执行完步骤s0之后执行步骤s1到S4，它们是同步执行的。
