令人有点吃惊的是，这样一个公认较好且广泛使用的差分格式竟然具有上述严重缺点，而且以往一直未见有人公开指出。 - Moving even slightly backwards , irregular or jerky steps with the hind or font legs , no clear diagonal steps , crossing either the fore or hind legs , or swinging either the forehand or the hindquarters from one side to the other , getting wide behind or in front and too many forward steps are serious faults

最后，针对外载与自重共同作用下，传统光弹性分析法中采用离心力场模拟重力场获得自重应力的试验投资耗费大、技术复杂且难度大和不安全等严重缺点，按照结构相似的模型理论，本文提出模型外载与自重并存变动外载的光弹性分析法，导出处理这个问题具体的相似律和试验原理及方法，进行了典型实验验证，指出仅用外载作用的模型试验，即不用离心力场模拟重力场的模拟试验，就可以获得上述两种载荷共同作用下的应力分析结果。
