Arbor Acres (AA) and Beijing Fatty Chickens (n=200, respectively) were raised under the same condition and were slaughtered at 28 d, 56 d and 90 d to assay the content of IMP and IMF in breast and leg muscle. The results showed that the IMP content of Beijing Fatty Chicken was significantly higher than that of AA (P<0.01), and also significant difference existed between them in IMF (P<0.01). The IMP content in breast muscle was higher than that in leg muscle (P<0.01), while the IMF was inverse (P<0.01). IMP content of female was a little bit higher than that of male (P>0.05). IMF content varied with growth rate, and showed no association with sex. IMF content increased with age, while IMP did not.展开更多
This paper introduces and comments the Data Quality Assessment Framework of IMF.Based on these,it provides an idea about the application of DQAF in our country.
在管道泄漏检测中,采集信号中的噪声会影响泄漏检测的准确性和泄漏定位误差。已有的管道泄漏去噪方法依赖经验参数的设置,去噪效果受管道条件和环境影响大。本文提出使用不依赖经验参数的EMD用于管道泄漏声信号增强。现有的EMD去噪方法...在管道泄漏检测中,采集信号中的噪声会影响泄漏检测的准确性和泄漏定位误差。已有的管道泄漏去噪方法依赖经验参数的设置,去噪效果受管道条件和环境影响大。本文提出使用不依赖经验参数的EMD用于管道泄漏声信号增强。现有的EMD去噪方法需要知道有用信号或者噪声的特征,不适用于特征随管道工程条件及环境变化较大的泄漏信号的去噪增强。提出改进的EMD信号增强方法,该方法不需要知道泄漏信号和噪声特征就可以提取与泄漏信号相关的IMF。在改进的EMD信号增强方法的效果分析中,信噪比提高可达16 d B。在大量实际工程管道泄漏信号处理中,使用改进的EMD信号增强方法之后得到的时延峰值更明显,漏点定位精度更高。展开更多
