The result demonstrates that the correlated weight matrix must be applied to solving transformation parameters according to least square adjustment.
其结果表明，按最小二乘平差求转换参数时，必须使用相关权阵。
The least Square estimates are not reliable when there exists multicollinearity in adjustment model.
当平差模型中存在复共线关系时，未知参数的最小二乘估计很不可靠。
