If there are four equations and only three variables, and no one of the equations is derivable from the others by algebraic manipulation then there is another variable missing.
如果有四个方程，只有三个变量，而且没有一个方程可以通过代数运算从其他方程中推导出来，那么就少了另一个变量。
Standards wars involve lots of variables, and understanding them often seems more an art than a science. They generally involve just two big players, and end in a winner-take-all situation.
标准之战涉及到很多变量，理解这些变量往往更像是一门艺术，而不是科学。他们通常只涉及两个大玩家，并最终在赢家通吃的情况。
