And then we compare the two testing methods, R2 and x2, with their capacity of discernment towards several Non-pareto Distributions. 同时通过考察两种数值检验方法R~2检验法和X~2检验法对常用非Pareto分布的识别能力,对二者进行了模拟比较。
An Intelligent detecting method of SMT solder joint fault is implemented depending on the above process. The samples indicate LMBP neural networks have better capacity of discernment about faults and improve the intelligent detecting precision and speed in comparison with standard BP neural networks. 经验证,对几种常见的缺陷,所建立的LMBP网络模型具有较好的鉴别能力,与标准的BP网络的鉴别结果相比,提高了智能鉴别精度和速度。
