This null finding should not be a surprise given that the transformation of the original poll results was just to add a constant of 100 to each previous poll outcome.
考虑到最初民意测验结果的转换只是通过向前面每个民意测验结果添加常数100完成的，那么这种零发现也不应当有什么令人吃惊的地方了。
It transforms the double-differential carrier observation equation using null space transformation so that it need not to resolve real-time three-dimensional position parameters.
对单个历元的双差载波相位观测方程进行零空间变换，避免了实时变化的三维位置参数求解；
