| 摘 要： | 根据线性方程组病态问题的几何特性,分析了导致汽车碰撞事故再现模型病态问题的原因.分析结果显示：病态的原因在于应用中模型的某些方程存在线性相关性.在此基础上,建立了确定存在线性相关性方程的方法,通过实例验证了该方法的有效性,为模型病态问题的处理提供了理论基础.

| Abstract: | Ill-condition in vehicle collision model was analyzed on the basis of geometric characteristic of ill-condition in linearity equations.The analysis result illustrates that the ill-condition reason is the linear relativity between certain equations.A method of determining the linear correlation was created according to above mentioned methods.An example proves that the method is effective and becomes a theoretical basis of solving ill-condition. |
