The average interspecific divergence was 3.860%, and special sites were found in each chicken breed which was the bases to identifying chicken breeds. The DNA taxonomy of Bar1 used NJ was consistent with morphological taxonomy among the six indigenous chicken breeds. However, the analysis of Bar2 sequences of COⅠindicated that they were lower polymorphism and no special site in most chicken breeds which was not benefit to identify chicken breeds. The DNA taxonomy of Bar2 used NJ was not consistent with morphological taxonomy among the six indigenous chicken breeds.
本研究选择的2段序列中,以Bar1序列648bp(712位点到1359位点)多态性最高,突变位点最多,为24个,品种间平均多态性为3.860%,6个鸡种在此序列中有各自不同的特异位点,NJ聚类分析6个品种基本被聚为不同的类别,与形态学分类基本一致,该COⅠ基因的Bar1序列用于这些品种鉴定是可行的;而Bar2序列进行序列多态性分析,由于其多态性低,大多品种没有其特异位点,NJ聚类分析6个品种基本被聚为不同的类别,与形态学分类基本一致,不利于品种鉴定。

Five main stalk crops planted in northern China including wheat, corn, broomcorn, soybean, and millet, were chosen to be the samples of the experiments. About seven morphological traits (such as plant height, ear length, ear weight, moisture content and so on) were measured in the crop mature period. The maximum shear force during shearing process, through static test equipment, at the second internode of the basal stalk, was recorded. And shear strength of each crop was calculated to find the differences of shear strength among different crops. The optimal regression models of shear force and morphological traits were obtained by multiple linear regression method with Statistics Analysis System. The equation based on the regression models was constructed.
本文以北方主要茎秆作物(小麦、玉米、高粱、大豆、谷子)为研究对象,试验测定了成熟期茎秆基部第二节间的最大剪切力及株高、穗长、穗重、含水率等七种形态特性指标,获得了静载情况下相关样本的剪切强度;分析比较了不同茎秆作物剪切强度的差异性,并利用SAS软件对茎秆作物剪切力与形态特性指标进行了多元线性回归,得到了剪切强度对形态特性指标的最优回归方程。

Due to its good effect in the reservation of information of signal abrupt change, mathematical morphology is often applied in the detection and location of short-term power quality disturbance, however, there is still a defect of invalid detection existing in partial detection methods based on mathematical morphology while some zero-crossing disturbances are detected. In this paper three mathematical morphology based disturbance detection and location methods, i.e., the method based on first-order derivation and morphological gradient, the method based on morphological gradient and soft threshold processing and the method based on dq decomposition and top-hat transform, are analyzed, that is, by means of simulation the adaptability of these methods in the analysis on the signals of voltage sag, voltage swell and electromagnetic transient oscillation is compared.
数学形态学因其在保留信号突变点信息方面有很好的效果,因此常用于短时电能质量扰动的检测和定位,但基于数学形态学的部分方法仍存在对某些过零点扰动检测失效的缺点,文章分析了3种基于数学形态学的扰动检测和定位方法,即基于1阶求导和形态梯度的方法、基于形态梯度和软阈值处理的方法、基于dq分解和高帽变换的方法,通过仿真比较了3种方法在分析电压暂降、电压暂升、电磁暂态振荡等信号方面的适应性,结果发现基于dq分解和高帽变换的方法在检测过零点扰动时具有很好的效果,因此选取这种方法对实测扰动数据进行了检测和定位分析。
