To overcome this problem, many authors proposed some biased estimators to alternate the least squared estimator. In some sense, these estimators improved the least squared estimator.However, the biased estimator was apart from the true value of parameter, so some statisticians proposed the notation of the almost unbiased estimator.
人们发现设计阵的"病态"是导致Stein现象的根源，为了克服共线性性，人们在文献中相继提出了许多有偏估计来替代最小二乘估计，这些估计从某种意义上讲，都改进了最小二乘估计。

While dealing with the multicollinearity of design matrix X , the ordinary least squares estimation is always helpless.
基于最小二乘法处理病态阵X共线性问题上的不足，线性有偏估计是改进最小二乘估计最直接的方法。

In Chapter 2, we introduce the new root power estimator of regression coefficients B when the design matrix present ill-condition.
具体工作如下：(1)针对设计阵A与C至少有一个病态时的情况提出新根方估计？

Wave front：波阵面
近来一些电生理资料表明,在电传导速度差异界面,波阵面(wave front)会出现向传导速度慢的一侧弯曲,而使波阵面轨迹呈螺旋状(spiral wave)[11]. 由于心肌病态和心肌的不匹配连接导致的各向异性[12],也会出现上述的波阵面向传导减慢区折弯.
