摘要
采用DASP小波分析模块,对反刍动物(绵羊、黄牛)的前胃各测点(瘤胃、网胃、网瓣口和瓣胃大弯)在4种生理状态下(采食、食后、反刍和正常)的舒缩应变时域曲线进行小波分解,给出不同频段谐波舒张和收缩应变幅值统计量,小波分析结果表明各测点在4种生理状态下主频与谱分析结果一致。
In this paper the time curve of extend and contract strain under four physiological situations (collect food,after food,ruminate and normal)of each measuring point(rumen,net stomach,ostium reticuloomusium and plait stomach is big curved) for the ruminate animals(sheep,ox)forestomach proceed decomposition through DASP analysis mold piece .Then statistics measure of amplitude value of extend and contract strain of different frequency band resonance wave were given out.The analysis result of small wave state clearly showed that each measuring point under four physiological situations main frequency and spectrum analyse are the same.
